3D printers are fairly simple: objects are produced layer by layer. 3D printers or fine powder (plaster, bioplastic, polyester, etc.) or liquids to print 3D models. The fine powders are connected to each other, so that they have a solid form. Liquids, such as photopolymer, are fixed by UV light. 3D printers are still too expensive for ordinary consumers, since the cheapest copies for approximately four to five thousand dollars on the counter. 3D printing is also not very fast. The printing of a 3D model sometimes takes hours or days.
Toch 3D printers offer many advantages. A 3D printer that can print parts of the body or skin is useful in a war zone. A computer can scan the wound of a soldier and then a 3D printer produces a layer of skin.
Food Printer
In the future, you might be a food printer in the kitchen. This means you never have to cook. Choose a recipe and the printer produces the food for you!
From Cartilage To Liver
The scientists begin to make cartilage. "It is formless and the internal structure is not very complex," explains Professor Hod Lipson of Cornell University from. "Then we produce complex tissue. Perhaps then followed a bone, or perhaps a liver."
Connecting
One of the biggest challenges is how scientists artificial tissue that was made with a 3D printer, to connect the human body. Take for example a new ear: that must be connected to small blood vessels. And we're not even talking about a complex component such as the heart or lungs.
