For a long time, the cost of 3D printing “bite”, was available only to the “elect.” 3D printers for home use appeared on the market. The novelty was presented by the company Cube, which can purchase its own 3D printer on the network of American retailer stores Staples: the purchase will cost only $ 1,299. While it is difficult to guess who will buy home 3D printers for what purposes: Raj and Howard, for example, in one of the series “The Big Bang Theory”, creating their own reduced copies, but nowadays there are quite a few cases of the unusual application of this super modern technology. Here are ten of the most unexpected things created using 3D printing.
1. Real gun
Of course, it was like a toy weapon that was destroyed and destroyed. A year ago, Cody Wilson, a law school student at the University of Technology and the head of the Defense Distributed project, announced that a gun should be created using a 3D printer in early March. 3D weapon test called “Liberator”. With the exception of the metal trigger, the gun was completely made of plastic, its cost was $ 8,000. Wilson and his friends successfully made six shots with 380-millimeter bullets, after which the butt-neck cracked, and the Liberator stalled. This example, in fact, is a wake-up call: to buy a weapon, you need to be capable and buy a 3D printer that anyone can receive.
2. Homemade violin
The first violin printed on a 3D printer is half technical, half a handmade miracle. Alex Davis (Alex Davies) used 3D printing to create a plastic violin body, which was then taped, like papier-mâché, newspaper, neck, and neck of an unusual violin made of cardboard. In winter, a video appeared on YouTube in which the world’s first violin, printed on a 3D printer, sang. Of course, this is not the Stradivarius, but for a self-made musical instrument is quite good.
3. Stem cells
High hopes for 3D printing – using this technology, you can create orthopedic and dental prostheses: for example, a year ago an 83-year-old resident of Holland had already implanted a titanium jaw printed on a 3D printer. Recently, 3D printers for stem cells have been created, more precisely, they have developed a special technique for 3D printing of human tissues with the help of stem cells. It should be noted that 3D-bioprinters have been encountered before, but this is the first model that uses embryonic stem cells as “ink”. According to its creators, stem cells multiplied by 3D printing are necessary for testing new drugs. A 3D printer can be grown with whole bodies.
4. The Dead King
In the fall of the year, archaeologists from the University of Leicester discovered the remains of Richard III, the last king of the Plantagenet family, who died in 1485. After that, Caroline Wilkinson (Caroline Wilkinson), a reconstruction expert at the University of Denmark, decided to create a computer model of the English monarch together with her colleagues, then to print it on a 3D printer. Thanks to modern technology, history has come to life.
5. Part of the skull
As already mentioned, high hopes for the creation of organs and tissues using 3D-printing. Here is another example: in March of this year, 75% of a person’s skull is on a plastic prosthetic surgery, a 3D printer transaction. Note that the replacement of a part of the cranial bone with an implant was successfully completed earlier, but for the first time 3D printing technology was used for this. New modern implant company “Oxford Performance Materials”, which uses 3D printing to create biological prostheses and other parts of the body.
6. Bionic ear
Researchers at Princeton University have printed an ear on a 3D printer. BioUkho was created from calf cells, polymer gel and silver nanoparticles: all of these components, which are located in each other’s body, were able to perceive radio waves that are outside of human hearing (you can hear much more than before). According to scientists, such an ear can be connected directly to the neurons of the brain, although there is already a big step in the development of bioengineering.
7. Own embryo
Would you like to see what your child looks like? The Japanese company “Fasotec” can arrange it: with the armed pictures taken by the magnetic resonance tomograph, specialists will print out a 3D model of your fetus. “Angel figure” is an exact copy of the embryo, enclosed in a transparent “lump”, resembling the mother’s tummy. In general, Fasotec specializes in the creation of 3D technology, as well as in cooperation with the Parkside Hiroo women’s clinic, which allowed this very successful project to be launched from a commercial point of view, because one 3D figure will cost the future. parents almost $ 1,300.
Continuum studio designers Jenna Fizel (Jenna Fizel) and Mary Hong (Mary Haung) created the world’s first bikini swimsuit printed on a 3D printer. The set received the conditional name N12 and consists of small round nylon plates connected to each other by thin springs (a sort of rope-clasp). Unique models of this model: all bras and pants can be made exclusively for individual orders and take into account the peculiarities of ownership – thus, this is an ideal bikini that does not cause inconvenience and discomfort. Fashionistas can purchase 3D bikinis in black or white for as little as $ 88.
Employees at Cornell University have access to the new technology “Solid Freeform Manufacturing”, which consists of using hydrocolloids as a 3D printer, which have hydrophilic polymers that form hydrogels that are actively used in the food industry. Thus, the scientists managed to print chocolate, biscuits, an apple, cheese, marshmallows, whipped cream, bread, a banana, and many more different sweets. Perhaps today, 3D-food looks too futuristic, but for 50–100 years it will be easier to press a printer button than go to the store.
10. Egyptian hairstyles
In ancient Egypt, it was not only the external decoration. Egypt wore wigs, which, in addition to the socio-cultural, even performed a purely practical function – they protected from sunstroke. Wigs were made from animal hair, silk threads, ropes and plant fibers that were intertwined in tight braids. Modern women can hardly agree with the idea that they have all the possibilities: researchers from McGill University using computer-tomographic models and 3D printing with an exact copy of ancient Egyptian wigs.
