SLS - Selective Laser Sintering — 3D Printing Process

Durable nylon parts with no supports required - ideal for functional prototypes and batch production.

A laser sinters powdered nylon layer by layer. No support structures are needed, which allows complex internal geometries, living hinges and moving assemblies to be printed in one piece.

Engineering parameters

SLS - Selective Laser Sintering parameters
Layer Height	0.1 - 0.12 mm — Consistent, isotropic mechanical properties.
Minimum Wall Thickness	1.0 mm — For moving parts or living hinges use at least 1.2 mm.
Minimum Feature Size	0.7 mm — Small features may fill in due to powder sintering.
Tolerance	+/-0.3% — With a minimum of +/-0.2 mm.
Support Structure	Not required — Powder bed self-supports overhangs and internal channels.
Max Build Size	380 x 380 x 580 mm — Larger parts can be split and assembled.
Lead Time	From 48 h — Batch lead time depends on quantity and finish.

How to order custom 3D printing

Samples start from 1 piece so the print can be approved before a bulk run.
Bulk pricing tiers start at 10 pieces and step down again at higher quantities.
A proof is sent for approval before the batch is produced.
Upload STL, STEP, STP, OBJ, 3MF, GLB or GLTF. Up to 20 files per request, 100 MB per file.
Keep walls above 1.2 mm and never below 0.8 mm for a reliable, printable part.
Your files stay confidential and are used only to quote and print your order.
Printed in our own factory, so no tooling is required and MOQ stays low.
Shipped worldwide by express courier, air or sea freight with tracking.
