2. Bones and cartilage

But they are already used by surgeons in real life. For example, 3D implants are used tosubstitutions100 000 Patients Later, the 3D‑Printed Hip Is a Decade Old and Going Strong / Orphopedia Design & Technologythigh bones. There are also good examplestransplants75% of a human skull replaced with 3D‑printed material / ExtremeTechprinted skull bones and cartilageauricleDoctors Transplant Ear of Human Cells, Made by 3‑D Printer / The New York Times. The next step in the application of this technology may be the replacement of small damaged areas right inside the person. This 3D printing method, according to the researchers,will allowS.

3. Dentures

Hands, feet and other parts of the body. Due to the simplified production process of the 3D prosthesisstandScientists Create Fully Automated 3D Printed Prosthetic Production Line / 3D Printing Industrycheaper and faster to create. In the standard scheme, you first need to make a cast of the remaining part of the patient’s limb, then cast a trial version from plaster, then try it on, correct inaccuracies, and only then proceed to create the finished product. In the 3D version, it is enough to collect measurements, correct the model on the screen and print it.

However, such prostheses do not necessarily perform an exclusively cosmetic function. 3D hands withtouch controlThese bionic arms make kids feel like superheroes / Insider, that is, a reaction to body signals, or withvibration response3D printed prosthetic arm providing feedbacks / Sculpteofor touching objects already exist. In addition, it is easier to replace a printed artificial limb after wear with a similar one by re-creating it according to the saved layout.

3D prostheses can be used not only in humans. For example, in Australia on a printercreatedMillie The Dog : Australia’s First Pup To Receive a 3D Printed Prosthetic Leg / HuffPostartificial leg for a dog

The speed and cost of producing 3D prostheses is a chance for many children: conventional options are too quickly rendered useless due to the active growth of the child. And a printed model can be created even for a one-year-old patient who is just learning movements: such a development has alreadypresentedFirst 3D‑Printed Sensor‑Operated Prosthetic Arm for Toddlers / University of Lincolnscientists from Lincoln University.

4. Food

But the choice of appearance is not the only plus of 3D food printing. Due to the possibility of virtual programming of the composition, the dishes created by the printer are easy to adjust to the desired nutritional value: control the calorie content, the amount of proteins, fats, carbohydrates, fiber, vitamins. This will make life easier for people who are on a strict diet for medical reasons. Also, the printer will allow you to cook the usual food, but from budget ingredients. For example, to form a fish fillet from seaweed. It’s in theoryshould helpSolving World Hunger with 3D‑Printed Food / The American Society of Mechanical Engineersin solving the problem of world hunger.

In the future, 3D printers can make the diet more ethical. For example, they will make it possible to stop killing animals for the production of meat products. One of the alternatives is herecreationWould you eat a steak from a 3D printer? / SBSmeat is completely based on vegetable ingredients.

Another way is to form “ink” for a 3D printer from a meat sample taken from an animal by biopsy. A device for printing using this technology was created at the Moscow State University of Food Production (MGUPP). True, for a 3D printer to be able to make a whole steak from a tiny piece of fabric, it takes several months. First, the sample is cultured in a bioreactor. When there are enough cells, they begin to form the base – from ingredients of plant origin. After that, animal and vegetable “ink” are alternately applied to it. As a result, the product retains both taste and texture.

The MGUPP 3D printer is capable of printing not only meat, but also, for example, chocolate or dough. University researchers plan to experiment with the technology further to expand their product range.

5. Clothes and shoes

3D printing in fashion expands the creative possibilities of designers, allowing for futuristic shapes that are difficult to achieve with conventional sewing methods. However, this is not the main advantage of the technology. 3D printerreduces3D Printing: The Solution to Fashion’s Waste Problem? / ÀLA.HAUSSEresource consumption: a thing or its element immediately appears in the right size – no extra shreds and threads remain. In addition, 3D fabric requires less water to make than cotton, and it can also be quickly created from recycled or recycled materials. In the future, printing things maydestroyCould 3D printing clothes be the future of fashion? / Thredfast fashion, allowing you to create them individually, ideally suited to the parameters and requests of the client.

6. Laboratory instruments

Printed instruments, due to the speed and cost of production, can help in research in poor countries. Now there are several projects that create budgetmicroscopesOpenFlexure: an open‑source 3D printed microscope / The Company of Biologistsfor diagnosing malaria in Tanzania.

3D technologies make science more accessible to amateurs as well. For example, Australian researchersdevelopedWant to do some science?

3D printing expands the creative possibilities: the machine can print curved walls, helical supports and other complex shapes. And the variability of building materials in this technology is large: concrete, sand, volcanic ash or eco-materials likerice husksThe Firts 3D Printed House «Gaia» Built With Soil, Rice Husks, and Straws / Surfaces Reporter.
