My Research Thus Far

What I've found out about 3D modeling that I didn't know before was that people have actually started research on uses in the medical area. They have found ways to make crutches, casts, etc. Just by using plastic materials. Another use is car parts. From cylinder heads, brake rotors, shift knobs, and vents. 3D printing can be used in the aerospace industry. NASA has been working with 3D printing to make a fuel injector for their most recent thruster project. It withstands 10x the heat that it could originally. There has also been 3D printed guns being produced by major companies. There are pocket-sized .38 caliber pistols that can fit pretty much anywhere. 3D printing has been used in the production of prosthetic limbs. People are using 3D printing all the way from weaponry to limbs that can change people's lives. There's plenty of debate on whether or not 3D printing is needed in everyday life. But if you ask me, I think it's going to help in the long run.
