Can a 3D printer print hard plastic?

Your best choice for making strong plastic parts is undoubtedly a filament based 3D printer as no other affordable 3D printers can make structural 3D parts nearly as strong.

How much tolerance do you need for 3D printing?

General information about tolerances in 3D printing In most additive technologies, the dimensional tolerance is at least 0.1 mm. This means that the deviations in 3D printing are greater than in other technologies, such as injection molding or CNC machining.
