3D printing is an exciting technology that allows makers to create objects from spools of plastic or vats of resin. Fused-deposition modeling (FDM) 3D printers are cheap, versatile, and capable machines that can create everything from board game pieces to prosthetic limbs. 3D printers are becoming more and more common in the world, so it’s important to know how to use them. In FDM102, you’ll learn all about what FDM 3D printing is, how it works, what its strengths (and weaknesses) are, and more.
