The bee is the first 3D printer in the world.
They work with a material made of their own body, which is formed at body temperature and has safe, biodegradable or even recyclable materials for consumption.
I started creating a 3D printing system that allowed me to generate collaborative sculpture objects using the best material in nature without hurting bees.
When I explained how I developed B-
Code, bio-polymer, live printer.
3D printing is now known as this process, but in the engineering and prototyping industries, the additive manufacturing that the technology was originally envisioned has been around for more than 40 years.
The word \"3D printing\" simplifies the concept so that one can imagine a traditional printer that prints on a plane consisting of an X-axis and a Y-axis, then add the vertical printer up and down motion on the plane, z axis, so that when the material is printed, it adds a layer on the other to make it a 3-dimensional one. Simple as that.
Additive manufacturing is similar to the way things are formed in nature, because the parts are built together, not like more traditional subtraction manufacturing techniques (such as cutting, stamping, and gouging.
Take the Heat, shoot, when the method of the industrial revolution, you understand the subtraction manufacturing.
A variety of additive manufacturing systems make it interesting.
For my readers, I won\'t go into it here in depth, but I know that there are print heads that store the heated monofilament and use a laser to heat and sintering the powder into a solid printer, an extruder that deposits Concrete and Clay, even systems that glue and cut a lot of paper, one by one to form their \"prints \".
At the Autodesk Pier 9 workshop, we have engineers, artists and designers working on all conceivable additive manufacturing systems.
Andreas Bastian, a former artist at Pier 9, joined a team that developed Autodesk Ember printer systems, printing plates hanging in liquid polymers and shining through UV light, telling the polymer where to solidify.
Madeline Green, a resident of my project at residential artists, is making 3D printed forms for people, life, and live, and huge robotic arms can \"see\" people, and built around them. Chei-
Wei is working on a system that allows people to print forms in the middle
As a 3D drawing system, people can draw tables on the goair.
Louis rodeitz designed a 3D printer for printing food.
Allen and Clayton have developed a 3D printer that works in clay and concrete. The B-
Code bio-polymer PrinterI was involved in additive manufacturing for the first time in the prototype industry about a decade ago.
At the time we called it part of \"growth\", which was a great way to convey the concept, very similar to what nature is building it.
It was the idea of planting parts that became the basis for me to develop a bio 3D printer.
The 3D printer I designed follows the principles of additive manufacturing and pushes the technology to a more sustainable, eco-friendly printing form approach. B-
The code is revolutionary because printing is made using completely edible, biodegradable, and completely sustainable bio-polymers that do not rely on oil, do not emit carbon, and do not produce waste. With the B-
Code printer, the bio-polymer is squeezed out of the nozzle, in this case the mouth of the Bee, \"stretched\" with a long line, one layer deposited on the other, and the air solidified.
The extruded bio-polymer is made of beeswax, which is a long
Chain alcohol plastic similar to ethylene, formed by fatty acids secreted by the glands of young adult bees.
The chemical formula of beeswax is C15H31COOC30H6I, which contains more than 300 separate chemical components, including Palm acid salt, Palm acid salt, fatty acid ester and long chain
This bio-polymer is similar to other early thermoplastic plastics used by humans before more toxic and persistent Petroleum
Basic plastics including latex, shellac, Gutta are beginning to be used
Gum, Horn and distortion.
The bees are printed with 2mm deviations of hexagon, which are gradually deformed into a circle.
The shape of the hexagon and circle is not accidental, but after millions of years of trial and error, due to its tensile strength and reduced overall surface area, these shapes are the most effective and strongest use of any material.
This allows the hive to maintain more than 50 times its weight in honey, pollen, and bees.
Bees work with simple logic similar to the code used in modern computing, including binary code
Then the statement, then the statement.
I call this set of instructions B-code.
When the number of available nectar exceeds the demand of the population, a set of feedback signals prompting bees to start building combs include triggers such as nectar streams, and the population begins to grow due to these additional resources.
The first signal of the flow of nectar is crowding, binary yes or no output.
The Yes output results in the next set of choices, which are determined by a very certain set of programs that are difficult to change.
The nearest comb, cell depth, and cell width are determined by the algorithm generated by the size of the bee itself, which is a real Vitruvian architecture.
The space between the Combs is equal to the distance the bees can reach from where she standsspace.
The cell width is determined by bees measured with the forearm, and the cell depth is determined by the length of the Queen, the length of the Queen\'s abdomen.
Building comb is just one of many tasks performed by bees, who undertake various tasks as guilds that are plastic and determined by factors such as age, available resources and population.
The work of young bees is to form wax scale, consume a lot of honey, and produce bio-polymers from the long chain fatty acids of processed honey.
The wax glands of the bees are located under the plates, which form the abdominal shield of the outer skeleton of the bee\'s abdomen, called the chest abdomen.
Liquid Wax is pushed out from these glands onto the plate under the outer skeleton and then stamped in a proportional shape before the air dries.
These stamps are called mirrors.
Wax scales are clear colorless, 3mm wide and 1mm thick. after bees chew wax scales with their lower jaw, wax scales become opaque.
The beeswax is feasible at temperatures between 91 and 97 degrees Fahrenheit, and the hive is usually kept at 92-
93 degrees, especially where the chicks are.
When bees need to make changes to the hive, they just need to chew and remodel the old comb and generate a new hive configuration as needed.
Think about it: bees use bio-plastics made by their bodies, build homes, nurseries and factories with their own body temperature and body chemicals, and for reusable materials, there is no need for other ecosystems or resources.
The honeycomb is almost colorless when it is initially formed, but over time, it will present more colors with oxidation, the Life of Bees
Cycle activity, contact with pollen.
I want to record the comb.
So I built a couple of prototypes, including a camera in the lid of the hive.
Bees are as wide as humans, but their color range is between UV and orange, and they do not see the red spectrum.
I want to record the comb.
Build the process without interfering with bees, so I chose to light it up with a red LED in the 655 nm range.
The early prototype used cheap bar LEDs and used a clear acrylic box to hold the bees, in addition to a dark lid to hold the camera and let the inside of the bee\'s Hive
There are a lot of problems with this system, and the worst is that the lights are enough to heat the hive.
Because the hive must remain 92-
93 degrees, condensation begins to accumulate and cause problems.
In addition, the led emits glare that is difficult to eliminate.
Finally, the focal length of the camera is too short, nothing but gopro, it turns out that this is a problem for what I want to achieve in terms of quality.
So I went back to the drawing board and redesigned the whole system with better lighting settings.
So I developed the light tube, which is located in the center of the hive, allowing the recording of files without extra heat, because the LEDs are located outside the transparent housing.
The light is evenly distributed throughout the core, and this material is called \"Endlighten \".
The color can vary depending on the LED color and for this item I chose an LED chip for a red and white LED.
I also used a potentiometer to dim the lights, a 700 mA step down so they don\'t blow up, and an oversized radiator to keep them cool.
All items are purchased online from luxstar star.
This light tube becomes part of the internal structure of the 3D printing, and once the printing is removed, it emits white color.
In addition to the color, a key feature here is that the heat of the lamp will drain out of the print space, so bees can live without the need for hard cooling.
I would like a multi-functional base to provide multiple forms and configurations for a more dynamic printing platform.
The base serves as a platform for the building, plus landing strips, a closed entrance to the building bed, and a feeding station that supplies honey to stimulate the wax building process.
I used cherry wood in this project because it is a plant that relies on bee pollination and breeding as a hardwood floor that can be used as a printing platform.
To cut the cherry, I used a 400 W laser cutter and nested my parts together so I could reduce the waste.
Then glue and Polish, laminate and finish it.
Bees naturally like wood and will cover the inner surface of the wood with propolis to seal the wood and produce habitable biofilm that repels harmful fungi, viruses and bacteria, colonies that grow beneficial biological groups, such as lactic acid bacteria.
To seal the exterior of the wooden base, I used a sealing device made of mineral oil and beeswax.
In this case, the print bed is a shell that surrounds the printer and limits the bee to this space.
The transparent housing is made of petg, a somewhat slippery material that prevents bees from connecting the comb directly to the housing.
The Petg is formed by heating by a vacuum heater, which pulls the material down to a plug mold made of a density board and uses a 5-axis CNC router for milling.
In the process of milling the two molds for the shell, I developed a better milling technique and wrote a manual for it, linked here.
I would like to explain some of the features of the shell.
The inside of the hive must be balanced, about 92 degrees Fahrenheit, with a humidity of 50-60%.
I have controlled the temperature by putting the case at temperature-
But as you can imagine, a plastic case won\'t breathe.
To make up for this, I ventilated the housing in several places where there was a shield opening.
I start with a lot of vents and know that bees will make their own adjustments as needed to reduce ventilation, Propolis is a plant
They collect resin-based glue in the wild.
Next, when bees come in and out of the printer, I designed a special interface for them, and for them, it\'s like a strange and familiar hive.
The printer will be placed in a storage room that can be ventilated to the outside world.
A tube extends from the bottom of the printer to the outside, but this material brings a problem with the presence of water
Tight, no ventilation.
Bees release moisture when they breathe out, similar to mammals, although the organs they breathe in oxygen are not lungs, nor are they breathing through the mouth, but air is treated by four helices located on both sides of the abdomen.
Intense social activity takes place at the entrance of the hive, where the bees are protected from checking every returned foraging when entering the hive, resulting in an increase in moisture released in this place.
I need a solution to put a circular tube into a flat opening at the bottom of the printer, so I designed an interface for the double
There is also duty and ventilation.
When I unplug the pipe and make adjustments, a special door can slide into the interface to keep the bee present, which allows me to work in the printer without being stung.
The second set of interfaces allows for gentle evacuation of bees after printing is completed and ready for harvesting.
This interface is-
Let the bees leave but not come back.
This is a slow game of consumption, when the bees are hungry, they leave and never come back.
This ensures that honey and chicks are completely removed before the print is harvested.
Bees will find that although they can\'t return to their old home, they are a new home within the sensing distance.
Bees will soon give up and start using the new hive as their home.
Once a sufficient number of bees have been evacuated from 3D printing, the print bed will be opened and the remaining bees will be manually reunited with their queen and spawn in the new hive.
