SLA - Stereolithography — 3D Printing Process

High-detail resin printing with a smooth surface - the standard for figurines, prototypes and consumer parts.

SLA cures liquid photopolymer resin layer by layer with a UV laser, producing the finest detail and smoothest surface of any common printing technology. Ideal for collectibles, master patterns and visual prototypes.

Engineering parameters

SLA - Stereolithography parameters

Layer Height	0.05 mm (fine) / 0.1 mm (standard) — Finer layers give smoother surfaces and sharper details.
Minimum Wall Thickness	0.8 mm — We recommend at least 1.2 mm for reliable parts.
Minimum Feature Size	0.3 mm — Embossed or engraved details down to 0.3 mm.
Tolerance	+/-0.1 mm — Or +/-0.3% for dimensions over 100 mm.
Support Structure	Required — Supports are removed and the surface ground/sanded.
Max Build Size	600 x 600 x 400 mm — Larger parts can be split and assembled.
Lead Time	From 24 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.
