Filament is the material we use for FDM 3D printing, and it's pretty easy to find. However, there are many types of filament and several factors to consider, such as heat and chemical resistance ...
If you’ve got a suitably high-end 3D printer, one solution to this problem is doing the supports in a water soluble filament; just toss the print into a bath and wait for the support to dissolve ...
(See our primer on 3D printer filament types.) Another technology used in 3D printing is stereolithography, commonly ...
