Manufacturers dye all sorts of 3D printer filaments on their factory lines; why can’t we? [Richard] takes this idea one step further by creating his own custom multicolored reels of nylon.

A filament of nylon may have a million or more molecules, each taking some of the strain when the filament is stretched. It was exactly what Du Pont had hoped for, and nylon was patented in 1935.

Different filaments will absorb water at different rates, depending upon their chemical composition and the environment, nylon being apparently particularly fond of a good soaking. It would seem ...

Japanese technology company Asahi Kasei and Italian manufacturer Aquafil are developing a novel materialfor 3D printing.

Other materials, like PETG, ABS, ASA, PC and Nylon are made from petroleum based sources. The first step to turn pellets into filament is drying, as the plastic readily absorbs moisture in its raw ...
