🧵 Filament
3D Printer Filament
If you are 3D-printing your arm, filament is the raw material for every link, bracket and gear. PLA is the easy default — stiff, dimensionally accurate and forgiving to print; PLA+ adds toughness for joints that take repeated stress. Dimensional accuracy (±0.02 mm) matters more than colour here: tight tolerances mean bearings and servo horns actually fit. Grab a reliable spool and a multi-colour pack for detailing.
