SLS Nylon
3D Printing
Tough sintered nylon, including a glass-filled grade with near-machined stiffness.
What SLS Nylon is good at
Selective Laser Sintering traces a laser across a bed of nylon powder, fusing each layer into the one below while the unsintered powder supports everything around it. Like MJF it needs no supports, but the material range leans harder towards structural work — including a glass-bead-filled grade stiff enough to stand in for machined or moulded components on short runs. It is the lane for brackets, housings and mechanisms that have to take load and heat.
| Layer thickness | 0.10–0.12 mm typical |
|---|---|
| Dimensional tolerance | ±0.3 mm on features under 100 mm; ±0.4% above 100 mm |
| Hole tolerance | ±0.3 mm |
| Minimum wall | 1.0 mm on small parts, scaling to about 2.0 mm on large panels |
| Maximum part size | 350 × 350 × 400 mm (minimum 5 × 5 × 5 mm) |
| Minimum feature | Holes from 1.5 mm; embossed or engraved detail 0.8 mm wide, 0.8 mm deep; powder escape holes 2.5 mm |
| Minimum clearance | 0.5 mm between moving or nested parts, or they sinter together |
| Surface finish | Grainy matte texture, bead-blasted as standard |

What people print with SLS Nylon
A cross-section of the work that lands in this lane.
Where it wins, and where it does not
Every process trades something away. Read the right-hand column before you commit a design — it is the part most services leave out.
Advantages
Why this lane gets picked
- No support structures, so complex, interlocking and internal geometry prints cleanly
- Genuinely tough parts — the general-purpose grades take impact and repeated flexing well
- The glass-filled grade approaches machined-part stiffness for short-run substitution
- Heat resistance far beyond anything FDM or SLA can offer
- Large build volume at 350 × 350 × 400 mm
- Parts nest three-dimensionally in the build, so batches are efficiently priced
Limitations to design around
Told straight, before you order
- The surface is grainy and slightly porous by nature. Bead blasting evens it out but does not make it smooth — this is not a cosmetic finish without sealing or painting.
- Colour choice is limited to white, greyish white and greyish black. Anything else means painting or dyeing.
- The glass-filled grade buys stiffness at the cost of ductility — it is noticeably more brittle, so avoid it for snap-fits and impact parts.
- Nylon takes up moisture from the air, which shifts dimensions marginally and reduces stiffness over time in humid conditions.
- Unfused powder gets trapped in sealed cavities. Add escape holes of at least 2.5 mm.
- Large flat, thin sections can bow slightly as the build cools. Ribbing or a thicker section is the fix.
- Heat-deflection numbers here are measured at low load (0.45 MPa); the safe working temperature under real stress is substantially lower.
