3D Printing for Good
3D printing is a form of additive manufacturing that can make use of a wide array of materials including metal, plastic, and glass to paper and ceramics. Interestingly, recent breakthroughs have shown that even living cells can serve as a medium for this technique. The process of additive manufacturing, in a nutshell, entails constructing objects layer-by-layer. This is wholly different from the use of molds and subtractive manufacturing methods.
While 3D printing has been around for the past 30 years, it remained inaccessible to the general public primarily due to the steep price tag. Fortunately, this is no longer the case as the technology has since become widely available. Now, consumer models can be purchased for as low as $1,000. For the longest time, the primary purpose of 3D printing has been for rapid prototyping. However, with recent advances in practices and the dramatic increase in its availability, 3D printing is now poised to make a great impact on production and the world economy.
