Nylon for Gears, Bushings & Functional Parts in Singapore
Nylon is the material we reach for once a functional part stops being about looking right and starts being about surviving thousands of cycles. Its fatigue resistance and self-lubricating surface make it the standout choice for gears, bushings and hinges that move against another part repeatedly — PETG or ASA will crack under that kind of repeated flexing long before Nylon shows fatigue. It also handles higher heat than PETG, at roughly 90°C, so it copes with a motor housing or a part near a warm enclosure that would soften in PLA.
The catch is that Nylon is genuinely the hardest of our materials to print well. It pulls moisture out of the air quickly, and a part printed from damp filament comes out weaker and rougher than one from properly dried stock, so every Nylon job gets dried and printed close to that drying cycle rather than off a shelf spool. It also warps more than PETG or ASA without a controlled, enclosed print, which is one more reason we treat every Nylon functional part as a small engineering job rather than a standard print.

Nylon (PA) is one of the toughest FDM materials, offering exceptional fatigue resistance and self-lubricating properties. Ideal for gears, hinges, and parts subject to repeated stress. It is hygroscopic and must be stored dry for reliable printing results.
The strongest functional plastic we print — engineered for gears, wear parts, and load-bearing assemblies.
Where Nylon shines
- ▸Gears & bearings

Tips for Nylon functional parts
- ▸Expect a slightly rougher, more matte surface than PETG or ASA — that's the trade-off for Nylon's toughness, and it's rarely worth sanding smooth on a part that's meant to take load, not sit on a shelf.
- ▸For a gear or bushing that meshes with another part, ask for the mating surface printed at a fine layer height — Nylon's self-lubricating property works best on a surface that isn't rough enough to grind against its partner.
- ▸Bushings and living-hinge parts print best with the hinge or wear axis aligned across layers, not along them, so repeated flexing works with the print rather than trying to peel layers apart.
- ▸Because Nylon absorbs moisture so readily, don't leave a finished part sitting in a humid store for weeks before use — Singapore's humidity will soften it slightly over time, the same way it affects the raw filament.
Example parts we print
- ▸Drive gears and idler wheels for a small mechanism
- ▸Bushings and bearing sleeves for a moving assembly
- ▸Living-hinge enclosure lids that flex without cracking
- ▸Tool handles and grips subject to repeated use
Recommended settings
| Setting | What we use |
|---|---|
| Infill | 30–40% for gears and bushings that carry real mesh load; lower for a living hinge, which relies on flex rather than density |
| Perimeters | 3+ walls on any tooth or wear surface so the load-bearing edge isn't just infill |
| Orientation | Print gear teeth and bushing bores flat on the bed where possible, so the load runs across strong layer bonds rather than trying to split them |
| Drying | Filament is dried immediately before printing — Nylon left exposed to Singapore's humidity for even a day prints noticeably weaker and stringier |
Starting points from our own machines — we tune per part before printing.
Frequently asked questions
Why is Nylon better than PETG for gears and bushings specifically?
Nylon's fatigue resistance and self-lubricating surface let it survive far more mesh or rotation cycles before wearing than PETG, which is tougher on a one-off impact but degrades faster under constant repeated motion. For a part that moves continuously, Nylon is worth its higher cost and longer print time.
Does Nylon need any special handling after printing?
Try to use or install the part reasonably soon after printing rather than storing it loose in a humid space for months — Nylon absorbs moisture over time, which softens it slightly. It isn't fragile, but if a part needs to sit in storage for a long period, PETG holds its properties more consistently.
