There is a specific category of part that nothing else prints well: gears that mesh, hinges that cycle, bushings that rub, clips that get flexed a thousand times. PLA snaps. PETG wears. Carbon fibre composites are too brittle.
PA6 nylon is what that category is for. It is tough, wear-resistant, and slightly flexible under load, so it absorbs stress instead of accumulating cracks.
What makes nylon different
Most printed parts fail in one of two ways: they snap under sudden load, or they wear away under repeated contact. Nylon resists both.
- Toughness. Nylon deforms before it breaks. A nylon gear tooth under overload bends and recovers where a PLA tooth shears off.
- Wear resistance. This is nylon's signature property and the reason it is used for industrial bushings and gears. Surfaces that rub against each other last dramatically longer.
- Self-lubrication. Nylon has a naturally low coefficient of friction, so meshing parts run smoothly without grease.
- Chemical and heat resistance. It tolerates oils, fuels and solvents that would attack PLA or PETG.
If you want nylon's toughness with more stiffness, fibre-filled nylon is the usual step up. If you want stiffness without nylon's difficulty, see PLA CF.
EMBERFORM PA6 (Nylon 6) at a glance

Dry the filament thoroughly before printing. This is not optional advice with nylon. An enclosure is strongly recommended, and a glue or adhesive layer helps bed adhesion considerably.
What to print with it
Gears, bearings and bushings, hinges, living joints, brackets under load, jigs and fixtures, and functional end-use parts. It is the right answer whenever a part has to survive being used rather than just existing.
Moisture is the whole game
Nylon absorbs water from the air faster than any other common filament, and a spool left out overnight in humid coastal air can be unusable by morning. Wet nylon prints with visible steam, audible popping, a rough foamy surface, and drastically reduced strength.
- Dry before every print, not just when the spool is new. 70-80 °C for 6-12 hours in a filament dryer or oven.
- Print from a dry box if the print will run for more than a few hours.
- Store sealed with fresh desiccant, always. Silica gel that has stopped changing colour is doing nothing.
- If a nylon print comes out weak and foamy, the filament is wet. It is essentially never anything else.
