3D printing could never be called an inexpensive hobby unless your last name starts with a “Rocke” and ends in a “feller.” While 3D printers themselves are rapidly dropping in price the plastic filament required as of yet hasn’t really budged much.

However, if you’re a high-volume maker then you might want to consider making your own filament with an at-home filament extruder.
