The technology of 3D printing would fit seamlessly into an episode of Star Trek. The process works via additive manufacturing; by putting several layers of a material on top of each another they are able to create a three-dimensional product. The possible applications for 3D printing are seemingly endless.

There are several different processes used in 3D printing; systems that use selective laser sintering or fused deposition modeling melt or soften materials into layers. One application for this process is for clothing manufacturing. By using recycled plastic powder, designers are able to make seamless clothing with almost no waste.

Another process uses the same concept as an inkjet printing machine. By spraying level upon level of a powder 3D printing is used to create models and prototypes. Jewelry makers were among the first to take advantage of this technology; using 3D printing they would create a model of a piece of jewelry, and the model to produce a cast. From there they are able to pour metal into molds, creating new pieces. Because of the ability to create molds, many manufacturing prototypes are now being created; crime scene investigators are using this process to recreate crime scenes.

3D printing is taking an even more advanced turn; high tolerance engine parts are being printed to incredibly exacting specifications, and joint replacement implants are becoming available. Because of the ability to create very specific, and very exact products, joints can be created as an exact fit for each patient, rather than a one size fits all approach. Even more amazingly, medical scientists are printing living cells which they use to create arteries and other tissues. The expectation is that eventually they will be able to create replacement organs, such as hearts and kidneys, using this process.
