This mini-review focuses on Fused Deposition Modeling (FDM) printers and what happens after acquiring your first 3D printer. In short, these printers melt plastic filament and deposit it layer by layer to create the final object. They are getting cheaper and easier to use, and nowadays it is not difficult to find good 3D printers for less than C500. At such a price, a 3D printer is one, if not the most, versatile piece of equipment you can have in a laboratory.
