'Group projects' are redesigned by the teamwork of 80,000 hardworking honey bees

A beekeeper works with the bees and their honeycomb mold at Dewars "3-B" project.

The buzz about 3-D printing just got the attention of 80,000 designers: Highlander honey bees.

To celebrate the launch of Dewar’s Highlander Honey, the whisky producer will be releasing the 3-B Printing Project, a unique artistic creation of two honeycomb structures entirely built by 80,000 honeybees.

“The 3-B Printing Project is both symbolic of the craftsmanship that goes into making each bottle of the new Dear’s Highland Honey and the modern attitude of our consumer — ‘the Drinking Man’ — who is intrigued by the innovation of 3-D printing,” says Arvind Krishnan, vice president brand managing director for Dewar, in a statement.

The project starts with a blueprint that mimics the bees’ natural environment while allowing them to gather nectar and pollen to create honeycomb. Visitors to the Dewar’s Facebook page will be able to watch a collection of “Live in the Hive” videos of the bees’ process beginning today at 5 p.m. and can enter a sweepstakes to win the final project.

Dewar’s Highlander Honey is a unique infusion of hand-selected Scottish honey with the natural flavors of the original Dewar’s White Label blended Scotch Whisky. The suggested retail price is $23.99 per 750mL bottle.

We give these little guys an A for effort on their 3-B group project.

  • Scientists made a liquid resin out of polymers which are good shock absorbers
  • They used this liquid resin to 3D-print a lattice structure to mimic cartilage
  • It has properties similar to real cartilage and could be used to treat patients
  • May be able to help patients who have no cartilage left in some joints, including knees, hips and even between vertebrae

Published: 13:00 BST, 8 June 2020 | Updated: 14:13 BST, 8 June 2020

People with worn out hips, knees and vertebrae are commonly plagued by a lack of cartilage, which results in bone-on-bone rubbing, inflammation and discomfort.

Now, scientists have used 3D-printing to create an artificial analogue of cartilage which could be used to treat these patients.

The synthetic cartilage has the same properties as the real thing and could allow afflicted joints to once again be cushioned and protected.

Creating synthetic versions of cartilage has long been thought impossible due to the complexity of the material.

But scientists at the University of Colorado used the precision of modern 3D printers to make an analogue. They made a 3D printed lattice structure using liquid crystal elastomers (LCEs), which allows them to build materials similar to real cartilage (pictured)

But scientists at the University of Colorado used the precision of modern 3D-printers to make an analogue.

Their research focuses on manipulating liquid crystal elastomers (LCEs), which are known for their elasticity and extraordinary ability to dissipate high energy.

Role of cartilage in the human body

Real cartilage is very versatile and has a range of uses in the body.

There are three different types of cartilage:

Found in the nose, trachea and ribs.

This type of cartilage has a glassy appearance when fresh, hence its name, as hyalos is greek for glassy.

It is dispersed with collagen fibres but is the weakest of the three types.

That is why it is easier to break a rib or your nose than it is to damage the cartilage in a person's knee.

Elastic cartilage provides strength, and elasticity, and maintains the shape of certain structures.

Found inside joints and has a remarkable ability to absorb dissipate energy.

It is the presence of this which allows humans to jump and run as it acts as a shock absorber in the body.

This is the strongest kind of cartilage, because it has alternating layers of hyaline cartilage matrix and thick layers of collagen.

For example, recent research has looked at using them as a shock absorber for American football helmets, to prevent concussions and CTE.

LCEs are also what what phone displays are made of, and the same material is also used to make Kevlar.

In Kevlar body armour, the polymers can absorb the enormous amount of energy from a bullet. Researchers managed to make these polymers soft enough to be used as the 'ink' in a 3D printer.

Medical researchers have been experimenting with LCEs for a while, believing it may be possible to make the most of their properties.

Real cartilage is very versatile and has a range of uses in the body. There are three different types of cartilage: hyaline (nose, trachea and ribs), elastic (outer ear) and fibro.

The latter is the type found inside joints and has a remarkable ability to absorb and dissipate energy.

It is the presence of fibro cartilage which allows humans to jump and run, as it acts as a shock absorber in the body.

If it breaks down due to arthritis, injury or old age, the bones are left without a cushion between them and they rub and grate on one another, which can be extremely painful and debilitating.

The scientists turned the LCEs into a honey-like resin and inserted this into a specialised 3D printer.

This allows it to be precisely sculpted, before being set in place by bombardment with UV light.

The UV light firms up the liquid and the material forms its own bonds, becoming stable.

From here, the computer printed the resin in a specific lattice formation, similar to honeycomb, designed to mimic the structure of human cartilage.

The layer hardens and, the researchers say, could be used as a shock absorber in future.


Heating the printed object in an oven heated to 1,300°C (2,300°F) burns away any excess material - leaving behind tiny glass particles which melt together.

According to the paper, which is published in Nature, the precision is only limited by the accuracy of the printer.

Dr Rapp said creating bespoke structures from high-purity glasses is difficult owing to the need for high temperatures and harsh chemicals.

Heating the printed object in an oven heated to 1,300°C (2,300°F) burns away any excess material leaving behind tiny glass particles which melt together. Pictured is a three-dimensional pretzel created using this technique

A microfluidic Tesla mixer cascade chip was created by the new printing technique. These structures are smooth and transparent with features as small as a few tens of micrometres

The new technique overcomes this issue by using a free-flowing silica nano-composite called 'liquid glass'.

These are then heat-treated to produce optical-quality, fused silica glass structures.

These structures are smooth and transparent with features as small as a few tens of micrometres.

Dr Rapp said two previous ways to shape glass in a 3D printing process have been demonstrated using soda lime glass heated to around 1,000°C (1,800°F) and a manual approach in which a glass filament is melted using a laser beam.

This honeycomb structure was heat-treated to produce a high optical-quality. By adding metal salts coloured glasses can be created using his method

In both cases coarse structures with high surface roughness were obtained.

His new technique produces surfaces with sufficient clarity and reflectivity for a range of optical applications.

'Glass is one of the most important high-performance materials used for scientific research, in industry and in society, mainly owing to its unmatched optical transparency, outstanding mechanical, chemical and thermal resistance as well as its thermal and electrical insulating properties', said Dr Rapp.

'However, glasses and especially high-purity glasses such as fused silica glass are notoriously difficult to shape, requiring high-temperature melting and casting processes for macroscopic objects or hazardous chemicals for microscopic features.

Honeycomb structure printed in fused silica glass was exposed to a flame of 800°C (1,470°F) showing the high thermal shock resistance of the printed glass part. The new process could allow unprecedented control over shaping of glass

'These drawbacks have made glasses inaccessible to modern manufacturing technologies such as 3D printing.'

By adding metal salts coloured glasses can be created using his method.

'This work widens the choice of materials for 3D printing, enabling the creation of arbitrary macro and micro structures in fused silica glass for many applications in both industry and academia', he said.

'This process makes one of the oldest materials known to mankind accessible to modern 3D printing techniques.'

Six more 3D-printing innovations

Increasingly used in dentistry and facial reconstruction, the world's first 3D-printed skull transplant was recently carried out in Utrecht hospital, replacing a 22-year-old's malformed skull with a plastic cranium.

Designer steaks maybe coming your way thanks to US start-up, Modern Meadow, which has printed artificial raw meat using a bioprinter. It doesn't come cheap, though – a printed hamburger costs around £200,000.

Developed by open source firm Defense Distributed, the plans for the Liberator handgun were released online last May, and downloaded over 100,000 times in two days, before the US Department of State had them removed. The Victoria & Albert Museum now has a copy of the gun in its permanent collection.

Dutch designer Iris van Herpen has brought 3D printing to the catwalk, with complex geometrical outfits made using a multi-material printer, and clothing customised to individual body scans.

Nasa is planning to print satellite parts in orbit, and even build objects on the moon, while private firm Deep Space Industries has launched a project to print spacecraft parts using materials mined from asteroids in a “microgravity foundry”. Norman Foster has also been working with the European Space Agency to design a moon research base printed from lunar soil.

For that extra personalised touch, US adult novelty company, the New York Toy Collective, gives customers the chance to “scan your own”, while Makerlove offers open-source files for people to customise their toys before printing in the privacy of their own home.

Spring Ingredients from A to Z

Warmer weather means an abundance of fresh, bright fruits and vegetables. From seasonal produce to traditional foods that come with the season, here are 26 ingredients and recipes found on Honest Cooking to kick off your spring celebration.

A is for Asparagus and Artichoke

Asparagus and artichokes are some of the first sure signs of spring. Both vegetables are delicious when simply cooked and served with a rich, buttery hollandaise sauce. To combine the two greens together on one delicious spring pizza, try the Artichoke and Asparagus Thin-Crust Pizza.

B is for Broccoli and Butter Lettuce

When cooking with broccoli, be sure to use the whole thing, stem and all! Try Crispy Tofu and Broccoli Bowls with Spicy Hoisin Sauce to use the traditional florets. Butter lettuce arrives in early spring when gardeners and farmers pull out baby plants in order to allow other lettuces to come to full size. The versatile green stays true to its name with a mild, delicious flavor. Try making a lettuce wrap with its silky leaves or a simple salad using spring’s radishes, herbs, and avocados.

C is for Chives

The garlic or onion tasting plant is ideal for adding bright green color to a dish. A great topping for a soup, an appetizer or eggs benedict. Try making savory chive donuts for great garlic flavor.

D is for Dandelion Greens

If you are looking for a leafy green with a nutritious punch this spring, try dandelion greens. The foraged plant can be easily found in your own backyard or at your farmers’ market. The bitter, peppery green has a robust flavor that can add interest to a plain lettuce or grain salad, it can be a nutritious addition to a smoothie, or a toned down side dish when sautéed. Try adding it to pasta or risotto, too.

E is for Endive

What could be better than a bitter lettuce that is perfectly shaped to hold delicious appetizers? Fill the leaves with cold, marinated shrimp, avocados, herbs, and other seafood for a truly refreshing appetizer. Or, try endives stuffed with a quinoa, blueberry, and basil salad.

F is for Fennel and Fiddleheads

Fennel is either loved or hated for its interesting anise and licorice flavor. Serve the herb root fresh with this Fennel Salad Topped with Sesame-Orange Tofu. For a different flavor, try it caramelized. Totally rich, this Caramelized Fennel and Shallot Pasta with Creamy Burrata will turn you into a fennel lover (if you aren’t already).

G is for Green Garlic

Green garlic is a true highlight of spring. It also goes by spring garlic or young garlic. Just like butter lettuce, green garlic is produced when the garlic crop is thinned out in the spring. Pickle your green garlic for later, add it to sauces, spreads, your morning omelet or to top a pizza or sandwich. Try this green garlic pasta with rich brown butter and a fresh hint of lime.

H is for Halibut

Although available year round, Pacific halibut season officially kicks off in March and runs until the fall. The fresh flavor of this white fish makes it perfect to serve with spring vegetables or spring-inspired pastas. This fish cooks quickly and is great for your first grilling adventure of the season.

I is for Iceberg Lettuce

A popular leaf in American salads, this mild green is great for flavorful sandwiches (especially BLT’s) that don’t need a additional spice from something like arugula.

J is for Jicama

Rather than debuting in the spring, the season for jicama is ending soon. So, eat it up while you can! Similar to a turnip, but with a milder flavor, jicama can be enjoyed raw with some salt and lime juice. Try it for a nice raw crunch in a pineapple salsa or cook similar to how you would a potato.

K is for Kohlrabi

This root is truly a refreshing sign of spring. Enjoy it raw for a delicious and addictive crunch that almost reminds us of a cross between watermelon and cucumber. Try this recipe for kohlrabi fitters or keep it raw and add it to coleslaw.

L is for Leeks

Leeks are grown all winter and harvested in the spring. With a mild-onion flavor, the leek is usually enjoyed sautéed or fried, but may also be eaten raw. Use leeks in any recipe that you would normally use onions and garlic. For a fun baking project, try leek and rosemary pork sausage rolls.

M is for Morels

The honeycomb-shaped, earthy-flavored mushroom only pops its head out in spring when the temperatures are warmer and wet. Because of low levels of toxicity, always cook these mushrooms before eating and be sure to obtain them from a trustworthy source. Try this grilled ciabatta with earthy morel mushrooms.

N is for New Potatoes

These thin-skinned potatoes are smaller, younger and some of the first of the crop to be harvested. Because of their small size and delicate flavor, we suggest incorporating them into simple dishes like salads. They are also wonderful bite-sized appetizers when roasted with herbs.’

O is for (Green) Onions

Shutterstock: JIANG HONGYAN

Just like green garlic, green onions are undeveloped bulbs harvested early in the season. Being a familiar vegetable, we know what enticing, subtle flavor they can bring to a dish, whether served raw or cooked. Try them in scallion pancakes.

P is for Peas

We all know that spring peas in a variety of forms will be dotting our tables shortly, especially at Easter celebrations. If you have a garden you also know that it is far too easy to eat all of the peas you have collected before you make it back inside. Truly get into the spring spirit with mint and pea salad, or try this pea burrata. For a smashed pea recipe, treat it like you would avocado toast. We love this go-to recipe for a pea and chive spread on crisp bread.

Q is for Quiche

Please excuse the lack of ‘q’ named ingredients—a recipe will have to do. Quiche is far from being a strictly spring food, but it is easy to incorporate spring vegetables and flavors into its eggy structure.

R is for Ramps

When ramps arrive you can be sure it is officially spring. Growing exclusively on the East Coast of the United States and Canada, and only in season eight weeks out of the year, this elusive member of the onion family has created quite the reputation for itself. Try Honest Cooking’s favorite ramp recipes.

S is for Strawberries

The berry kicks off its season in April and will continue bringing delicious joy until about August. From savory salad preparations to sweet and summery strawberry shortcakes, these berries really put us in a warm weather mood. Put the strawberry into cakes, plop one in your next drink, or try a wild sorbet.

T is for Turnips

Turnips have a wide range of colors, shapes, and varieties that are available throughout the year. However, they are at their prime in the fall and spring. Their greens have a bold, mustard-like flavor, but the root is more mild and starchy. Try this Portuguese rice recipe to use turnip greens.

U is for Ugli Fruit

Get the last of the ugli citrus fruit before it leaves for the summer. Grown in Jamaica, the ugli fruit is teardrop shaped with a unique green, wrinkly skin until it ripens and becomes orange. Juice the citrus for your next smoothie, juice or cocktail or incorporate it into baked goods or salad dressings.

V is for Vidalia Onion

The Vidalia onion grows under the soil during the winter months and is ready to be enjoyed in early spring. This sweeter onion is used all year round in cooking, but it is fun to give it its special spotlight in the spring.

W is for Watercress

Take advantage of watercress during its spring harvest and add the delicate-looking leaf to your meals for a refreshing and peppery flavor. Check out this goat cheese dip that goes from plain to unique with the addition of the green and blueberries.

X is for X Marks the Spot

The spring season is where its at, but for this spot on the alphabet we are currently accepting submissions for spring foods that start or, let’s face it, even contain an ‘x’.

Y is for Yolks

There aren’t many spring fruits or vegetables that begin with the letter ‘y’. However, when you think about it (or really need a word that starts with ‘y’) you will notice that eggs, especially yolks take the spotlight in spring. Around Easter, eggs are deviled, pickled, dyed, and cooked every which way for brunch. Yolks become apparent in salads showcasing baby greens and steal the show in rich sauces drizzled over asparagus. Also, what kid hasn’t wondered if an egg will balance during the spring equinox?

Z is for Zucchini – Plant it

Zucchini is not ready to eat right now, but if you want to enjoy the squash and its blossoms later in the summer, now is the time to plant. Once they arrive, be sure to make these baked zucchini fries, or grate and freeze some for the winter months when you are craving this chocolate and yogurt zucchini bread.

The 3D Print Canal House is being printed using the KamerMaker, which means room builder and pipes plastic lines of molten plastic on top of one another according to computerised plans – just like a gigantic version of a home 3D printer.

The machine, which is made by Dutch firm Ultimaker, pipes lines around 10 times as large as a standard 3D printer and can create pieces of building that are 6ft wide, 6ft deep and 11ft tall (2metres by 2meters by 3.5metres).

The KamerMaker machine pipes thick lines of molten plastic (pictured) that are around 10 times as thick as the lines drawn by 'home' 3D printers

The 3D Print Canal House is being printed using the KamerMaker, which means 'room builder' and pipes plastic lines on top of one another according to computerised plans - just like a gigantic version of a home 3D printer

Construction has been under way for around one month and so far a 9ft (three metre) high corner section has been printed, weighing 397lbs (180kg), according to The Guardian.

Giant pieces like the corner will be used much like Lego bricks and stacked on top of one another to make the house, which is inspired by the traditional Dutch gabled town houses.

The design consists of a number of rooms – each with unique features - which will be designed separately on site, before being assembled into the house, so experts can test their safety.

Using computers to design and print the structure means that architects can create a house that has structural integrity, while also looking aesthetically pleasing so that the interior and exterior of rooms can be printed in one part.

There is space within the plastic block walls for cables, pipes and wiring because of a honeycomb lattice design.

The KamerMaker machine (pictured), which is made by Dutch firm Ultimaker, can create pieces of building that are 6ft wide, 6ft deep and 11ft tall (2metres by 2meters by 3.5metres)

Here a small-scale 3D printer quickly makes small, scale sections of wall, the likes of which will be built for real by a giant printer

The plastic used to print the house is ‘a renewable, sustainable, strong, tactile and beautiful material that can compete with current building techniques,’ according to the architects.

Scientists are currently testing different samples of materials to create the perfect one but the final ‘hot melt’ product will be approximately 80 per cent natural as it is a bioplastic mix made up of microfibres and plant oil.

Hedwig Heinsman from the architect firm said: ‘We’re still perfecting the technology. We will continue to test over the next three years, as the technology evolves… It’s an experiment.’

At the moment, the lattice blocks are being filled with less sustainable concrete, which would make the structure, hard to recycle, but this seems to be an intermediary step.

Here are some small examples of different types of walls, and the honeycomb cavities are easily visible

If the house is a success and the technology honed, the architects hope that 3D printing could mark a new era in building houses.

The cost of transporting materials and waste could be cut using the technique and the final buildings could be dismantled and moved in units, or completely recycled.

Mr Heinsman said: 'This could revolutionise how we make our cities. This is only the beginning, but there could be endless possibilities, from printing functional solutions locally in slums and disaster areas, to high-end hotel rooms that are individually customised and printed in marble dust.’

Areas of the City [ edit | edit source ]

Entrance and Basement Area [ edit | edit source ]

The City is entered via a large metal hatch at the bottom there are arrows painted along the foundation leading to this hatch. A decently sized raft, which the player will probably have at this point, cannot fit in this hatch, so it is necessary to anchor outside and swim in. From here, a large underground section must be explored to reach the upper, dome-encapsulated levels. Quite a few Lurkers can be found in these tunnels, and these ones are tougher than those encountered on Vasagatan, so preparations for combat are recommended (ideally a Machete or a Bow with Metal Arrows).

Once entered, the player will find signs that lead to different areas of the basement, although many doors will be locked from the other side. These will serve as an easy way to get back to the raft, once the areas have been fully explored. The first area encountered is the cafeteria, which is a large room with a few tables and cooking equipment. Some loot can be found here as well as a note. A Generator Part is found here, which is needed to repair the generator in the Storage Area.

Storage Area and Connected Rooms [ edit | edit source ]

One of the puzzle areas in Tangaroa is the Storage Area. Once the player reaches this area, they will see a room full of containers and a crane on top of them. To complete this puzzle, the player must have found three Generator Parts in the previous underground areas - these can be placed in the generator found by going up the ladder. Once done, this will power up the crane and activate the controls.

The goal of the crane puzzle is to move the containers in such a way that a path is created from where the player enters the room to the doorway marked "Surface Access". Containers can only be moved to adjacent empty spaces as they don't lift all the way to clear the neighboring ones, so care must be taken to build a path such that the player always has empty spaces to maneuver containers around. The initial empty spaces are in front of the storage access door, and there are two more right next to where the crane's initial position is. The last thing to note is that the containers with yellow-black striped lines on top of them are actually hollow in the directions the lines indicate, meaning they can be used in the construction of the path. There is a secret room directly underneath the control platform for the crane that contains Titanium, food, and a Machete, along with other loot. Upon entering this secret room, the player gets the hidden Steam Achievement Boxed In!

Once the player completes the puzzle and goes through the doorway, they will come into a room with the Water Pipe blueprint and a surface access hatch. However, the room above has been flooded, and water will start spreading to the basement area once opened, which will stop any more Lurkers from spawning in the basement. The room above this hatch is completely inaccessible, and the ladder leading to it becomes unclimbable upon opening the hatch. The player must head back to the Storage Area to climb a previously inaccessible ladder to the Plantation, now reachable with the help of the rising water level. There are air pockets on the roof along the way, but it is recommended to carry an Oxygen Bottle and Flippers into this area.

Plantation [ edit | edit source ]

The next area is where the Tangaroans attempted to grow their food, but were thwarted by a beetle infestation. It consists of a series of connected rooms, which have numerous crop plots sticking out of a flooded floor, and the occasional stack of boxes, bags, or other debris. The water in the floor becomes electrified every couple of seconds, zapping the player if touched. To avoid being electrocuted, the player must traverse the rooms by jumping from platform to platform, or running between them within the timing of the water being unaffected by electric current. In terms of items, the player can find two new consumables, namely Strawberries and Bananas - as well as their seeds.

The area is electrified due to four faulty electric panels located on the walls, that have to be fixed with 3 Tape each. These panels will also open certain doors when fixed. The player will find enough tape to fix the first panel in the plantation itself, but will need more tape which can only be found on the upper levels. Since the last location of the city can only be accessed through the plantation, the Tape is effectively a gate forcing the player to explore the whole city. Once the player has fixed all four panels, the water will become permanently safe to walk on and the door to the elevator will open. In the room connecting to the elevator, the Blueprint: Electric Purifier can be found.

The Plantation area also connects to the Surface Access tunnel, providing the player a way to get to the above ground area of the city.

Main City Area [ edit | edit source ]

Once the player reaches the surface, they will encounter a massive area that is very similar to most modern cities today. It is laid out with streets that have their own unique names and green areas with trees and benches, all centered around a tall black tower that represents the centerpiece of the city and the second to last location that must be explored. The streets are patrolled by the aforementioned Butler Bots, which cannot actually be killed but disabled, with the use of weapons. Four Metal Arrows will disable one of these robots, allowing the player to extract a Tangaroa Keycard from its head. One Keycard is needed to explore one skyscraper, since the door on its bottom floor is locked and can only be opened with a keycard, which is consumed on use. It is important to note that the robots eventually restart themselves, so if a player needs more keycards they can always disable the same robots multiple times.

According to the Story, which is revealed in the notes found around the city, a big riot took place on the surface before the fall of Tangaroa. As a result, the streets and green areas are littered with garbage and debris, none of which can be harvested for resources.

Around the city, the player can find five exits which can be activated by interacting with them. Once this is done, an emergency exit will open and an inflatable bridge will be deployed, allowing the player to access the city directly from their raft, without going through the underground area.

Skyscrapers [ edit | edit source ]

Surrounding the central tower, there are numerous concrete skyscrapers, which can be explored for loot and Tape, but may be guarded by a Lurker, so be careful. Seven of these can be accessed directly from ground surface, but one of them provides access to the central tower via Ziplines. To prevent the player from immediately exploring the tower, repairing the aforementioned electrical panels is required to enter it. It must be accessed underground through the Plantation, and only after all four panels have been repaired. To access the other seven skyscrapers, the player must use keycards and the readily available elevators. Some buildings only have one floor that can be accessed, while others have two or three. Most buildings have two doors on each floor, and these mostly lead to two different apartments. One of the skyscrapers in particular is an office building, which have the two areas connected. Apart from exploring the inside of these buildings, the player can usually access a balcony area of the apartments, which contains extra loot and access to numerous hidden areas. These locations are often hinted at with broken railings, electrical wiring that acts as Ziplines, or plank ramps, all of which allow the player to access otherwise unreachable areas.

In these apartments, which show different levels of luxury (although all indicate high standards of living some are more decorated than others) the player can find numerous rolls of Tape and Tokens. Occasionally, the player may find rooms sealed off with Tape. These can be cut with a Machete, allowing the player to find Loot Boxes, containing higher quality loot. These can be briefcases that contain Metal Ingots, Glass, and even the newly available Titanium Ore. The apartments themselves are repetitive (with some unique exceptions such as the office building and the birthday party apartment) but the loot can spawn in different places so the player should take care to explore everything thoroughly.

Shops [ edit | edit source ]

Around Tangaroa there are four shops: a VR games store (V Are Arcade), a barber shop (Sea Side Barber) a hamburger place (Chi's Burgers) and a fashion store (Floating Fashion). These can't actually be accessed or explored, but play a vital role in the story, as they are part of the last puzzle in the Second Chapter.

Main Tower [ edit | edit source ]

The large tower in the center of the city is where the player must go to finish the story of the Second Chapter. At the base, it has a door which is initially locked. Next to the door are four vending machines that require Tangaroa Tokens in exchange for a number of items, some of which are Tangaroa exclusive. Available items range from Bottle of Fresh Water to Tangaroa Paintings, to Tangaroa Plants and even a grand Piano. It is important to note that the tokens respawn once the player is far enough away from the city, making all items purchasable on a single save file.

The tower itself has three levels: the ground floor (0), the room in the middle of the shaft (1) and the top area (2). The tower must be accessed by a network of Ziplines (which in reality are cables connecting Electric Poles) these are reachable only through a specific Skyscraper, whose door has a "keycard reader malfunctioned" sign, and which can thus only be accessed through the Plantation elevator. To reach the elevator, the player needs enough tape to fix all electric panels in the Plantation. Once this is done, the elevator door will open and the player will be able to explore the last apartment building going to the balcony of this one will lead to the main attraction in the form of a cocktail party area. Going further up some stairs, the player is led to a zipline, allowing access to the bottom-most platform of the tower. The player must then find a ladder leading to the platform on top, from which they can call the tower elevator. The lower part of the tower is just a room with the street level door, which can now be opened for easy access into the tower.

When the player goes up via the elevator, they will reach a room with a door and a keypad to the left of it. The Blueprint: Large Storage can be found here. The keypad says "Emergency Bridge Launch" and its code must be deciphered with the help of the adjacent note to launch the bridge, which is the actual last location related to the city. The provided note names four streets with the drawings of the four aforementioned shops. To decipher the code, the player must visit the shops, and write down the respective numbers on their doors. The street names are mentioned in the note to help find the shops. Once all numbers are found, the code is revealed: the numbers, ordered from top to bottom. Entering the correct code will show "success" on the keypad and the bridge will be launched, landing in the ocean outside the city.

Bridge [ edit | edit source ]

When the player completes the code puzzle and the bridge launches, it will land in the water close to the city. The player must then locate it visually, swim/sail to it and climb a ladder on the side, leading to an access hatch on the top. The bridge is a circular structure with a pillar in the center and is filled with control panels, indicating this is the place where Tangaroa was steered. A couple of notes can be found here, both story related and the code note leading to the next area which will be added in the Third Chapter. Also found here is the Blueprint: Water Tank.

There are also a couple of paintings of the captain of the city and the founder of the Tangaroa project, James Tulley and Max Landshoff respectively.

Georgia Tech has made manufacturing a research priority, and the results are surprising

Published: Monday, April 2, 2012 - 13:18

I n a busy laboratory at the Fuller E. Callaway Jr. Manufacturing Research Center, a researcher from the Georgia Tech School of Mechanical Engineering is using a novel digital technology to cast complex metal parts directly from computer designs, dramatically reducing both development and manufacturing time.

Nearby, at the School of Industrial and Systems Engineering, researchers are working with a large U.S. avionics maker to speed new-product production using specialized software that automatically generates simulations of the manufacturing process. And across campus in the College of Architecture, a team is working with an international corporation on digital techniques that allow entire concrete walls to be custom-manufactured to architectural specifications.

The 3D SIP-CESE MHD model (Feng et al. 2007 Hu et al. 2008 Zhou et al. 2008 Zhou & Feng 2008 Feng et al. 2009) has been greatly improved from the consideration of the following aspects: grid system, CNIS method, time integration, magnetic field divergence cleaning procedure, and volumetric heating. For the grid system, we introduced a composite mesh that consists of six identical component meshes to cover a spherical surface with partial overlap on their boundaries. Like the Yin-Yang grid (Kageyama & Sato 2004) and the cubed sphere grid (Ronchi et al. 1996), the important features of the six-component composite mesh are that these identical component grids with overlapping boundaries can be obtained from each other by coordinate transformation that makes the coding more efficient and concise, and each component with the quasi-uniform grid spacing is just a part of the latitude–longitude grid avoiding mesh convergence and singularities at the pole regions. Meanwhile, the grid system allows easy-paralleling not only in the "(θ, )" directions but also in the radial direction. The CNIS method can reduce high numerical dissipation in regions with small CFL numbers and thus keep the accuracy of the solution.

In time integration, the multiple time-stepping method is used by dividing solar–terrestrial space into six subdomains. This method enhances the convergence stability and speeds up the calculation by easing CFL number disparity due to spatial grid size variations and the different orders of magnitude of solar wind parameters such as plasma density, the Alfvén velocity, and IMFs from the Sun to Earth. In order to fix the magnetic field divergence error caused by the numerical scheme, the F-cycle iteration can maintain the ∇ B error to an acceptable level of 10 −6 , and it has a proper time-cost/performance of about 40% CPU time in time step. The combination of CNIS and a multigrid Poisson solver is particularly efficient in enhancing solution resolution near the HCS. For the acceleration of solar wind, volumetric heating source terms are considered by using a 3D distribution profile based on the expansion factor fS and the angular distance θb. Although our definition of fS is slightly different from the original (Wang & Sheeley 1990 Arge & Pizzo 2000 Arge et al. 2004), its role has the same functions as claimed by Nakamizo et al. (2009) that is, this heating is weakened at the location where the magnetic field is in overradial expansion (fS>1.0), and also it is strengthened at the location where the magnetic field is in underradial expansion (fS < 1.0).

The use of angular distance θb, which can realistically specify solar wind speed at the boundaries and the interiors of coronal holes, can effectively distinguish the high-speed solar wind from the low-speed solar wind (high-speed wind emanating from the center of a coronal hole has large θb and low-speed wind from the hole boundary has a small θb). Our heating profile configuration can better lead to a non-uniform heating distribution reflecting the topology of the magnetic field in a key region of the solar wind generation. Meanwhile, our numerical results show that the Wang–Sheeley relationship yields higher predicted wind speed values at the source surface than the MHD model does. Also, the MHD model predicts speeds closer to the observation than those predicted by the Wang–Sheeley relationship.

Overall, our model can produce all the physical parameters everywhere within the computation domain. This may imply that the solar surface global heliospheric structure connection can be predicted by the simulation up to a generally acceptable level, although many unsatisfactory points remain as discussed here.

Differences occur due to many factors such as the uncertainties in photospheric magnetic measurements (especially in polar regions), the imperfection of the potential magnetic field approximation, the occurrence of some coronal mass ejections (CMEs) during CR 1911 (1996 June 28–July 25), 6 the shortage of more sound physical-based and observation-supported heating mechanism, and the neglect of interaction between solar wind and interplanetary discontinuities. Although our heating consideration gives favorable numerical results, we have reasons to believe that volumetric heating alone cannot be the only acceleration process acting on the solar wind and that other presently unknown sources are needed to act within the region between the lower corona and the source surface. Further characterizing and quantifying of the key physical processes/mechanism will clarify an operational route to more physically integrate realistic coronal heating modules into 3D MHD codes.

Incidentally, our model validations for some other CRs show that the numerical results for the CRs during solar minimum are usually better than those for the CRs during solar maximum, when compared with observations in the solar corona and at 1 AU. This may be due to the fact that the currently used initial input of a magnetic field based on the potential field model cannot take into account the observed heliospheric open flux from active regions and CMEs by way of interchange reconnection frequently occurring at solar maximum (Cohen et al. 2007).

More available spacecraft observations will of course equip us with new findings about the coronal heating mechanism, the causes and mechanisms of CMEs' initiation, CMEs' 3D structure, and the interplanetary evolution process. The recently launched Solar Dynamic Observatory (SDO) will help us understand the Sun's magnetic changes. SDO will determine how the magnetic field is generated and structured, and how the stored magnetic energy is released into the heliosphere and geospace. STEREO observations can provide new insights into the 3D structure of CMEs and their evolution in the heliosphere which can directly be compared with existing models and simulations. Comprehensive data and analysis with multiple spacecraft (such as SDO, STEREO, SOHO, ACE, WIND, or other future missions) will probably help us develop the ability of including physically realistic coronal heating modules into 3D MHD codes, improve the determination of the structure of the ambient solar wind, and further numerically characterize the 3D propagation of CMEs through the heliosphere. Other aspects for space weather event simulations in 3D MHD from the Sun to Earth can follow suggestions made by Dryer (1998, 2007) and Wu et al. (2006). These will be our avenue to future improvements. In particular, this model is being used for the propagation study of transient events from the Sun to Earth.

This is a really cool project, but how sturdy could those pieces possibly be? I can’t imagine the concrete is very strong when printed in layers like that. Unless he plans on filling the spaces in between the sidewalls I feel like you could demolish the walls with your bare hands using little effort. The big benefit from printing would be from how much less concrete you would have to use since you can do the same thing by filling wood molds of each piece you need to make. The printed concrete is essentially the wood mold you would make. Yes, it would be easier printing complex shapes that would be hard to reproduce with wood, but most thing can be broken down into simple parts. I just don’t see this being cost or time beneficial in most cases.

Either way, it is great to see creative thinking at work. I don’t know a lot about concrete in general so I may be completely wrong with my assumptions. I’d love to see more in the future.

Fiber reinforced concrete seems to be a thing in the building industry (but fairly pricy)…If one could get the fibers to stick out of the printed layer, the next one would have something to adhere to…

Or you could just fill the hollow structures with something like glass reinforced polyurethane foam :D

The layers make no difference. One layer bonds to the next just as concrete does without layers. The nozzle output is 20mm x 5mm, the bessa blocks in my house are only 20mm thick. Moving one step ahead and making it so that higher blocks have interlock tabs with blocks below would be a great time saver and you could have blocks of any shape.

Great! So now we need this in every hackerspace, to build new buildings and space for the folks there!

Very nice but china already print a house of concrete

Nice. Are these for ghost suburbs or ghost vacation homes?

The nice thing about using this for ghost houses is that, since no one is actually living in them, you don’t have to worry about how well this completely uncertified (and, likely, minimally tested) building method stands up against things like tornadoes, hurricanes, or earthquakes. Also, as Menno is suggesting, since the Chinese have done it any further development of similar technology is a complete waste of time and the guy in this Hackaday post should be ashamed of himself. /s

You should be ashamed of yourself for putting down his efforts. Nothing is perfect in the beginning, and he’s doing it in a garage without a bazillion dollars of venture capital behind him.

Umm, I can’ tell if you’re trying to be serious but the “/s” at the end of my post stands for sarcasm. I was knocking on the absurdity of Mennos suggestion that some company in China doing this already has anything to do with whether this guy should be bothering to spend time working on this project.

This system of Concrete Application has far reaching benefits to our global community. There are wonderful technologies coming online in the next few years that are going to bring about positive change utilizing this gentleman’s genius Concrete Printer.
Firstly the company has a publicly purposed plan to build food growing Concrete Domes called FARMDOMINIUM’s with Concrete Habitat Ring Environments for Community, Further the online video at teaches us that this Concrete Printing is about to change the world by providing safe long lasting malty generational homes and farms that will be impervious to outdoor environmental consequences. things like tornadoes, hurricanes, or earthquakes. .Really this Concrete Printing is very applicable and needed.

To the global business community I personally ask that we all support this man’s technology and his company please.

I’m a retired Concrete Finisher, I wish I was 19 again, I would have loved to worked Concrete Printing Domes for Food and Safe Clean Durable Homes.

Our creative director led this effort while working at a previous company. The LSU Football Operations Center visitor experience was an immersive branded sports environment which showcased their extensive achievements and awards. We worked closely with the football coaching staff, the athletic department and local newspapers to develop a series of curated historic displays with a distinctive graphic design style that would show consistently across many decades and groups within their storied football history. We also developed the 3-D trophy case design to fit into the existing architecture of the building. Integrated specialty team position feature displays were also created throughout the facilities to celebrate group achievements.

Our creative director led this effort while working at a previous company. Michael Waltrip Racing wanted an integrated fan experience at the front end of their massive race shop. We scripted an immersive visitor experience to showcase each team driver followed by a complete breakdown of race car design and assembly. From start to finish, we provided 2D and 3D design along with video content, motion graphics and interactive content for this immersive fan experience.
