|Hod Lipson has developed a 3D fabrication-on-demand printer that can be built from a $3,000 kit. How cool is that?|
Fabbers build 3D objects by carefuly depositing materials drop by drop, layer by layer. Slowly but surely, with the right set of materials and a geometric blueprint, you can fabricate complex objects that would normally take special resources, tools and skills if produced using conventional manufacturing techniques.
Lose a chess piece? Need a new pair of flip flops? Make it yourself with a 3-D printer. You may have seen similar technology used on American Choppers, but now you can afford to bring it on home. This rapid kind of prototyping takes a CAD design, transforms into horizontal cross-sections and then creates each cross-section in physical space, one after the next until the model is finished.
