Metal SLM / DMLS — 3D Printing Process

Direct metal printing for end-use metal parts in stainless steel, aluminium and titanium.

A high-power laser fuses metal powder (SLM/DMLS) into fully dense metal parts with excellent mechanical properties, ideal for jigs, brackets, tooling and end-use components.

Engineering parameters

Metal SLM / DMLS parameters

Layer Height	0.02 - 0.05 mm — Fully dense metal parts, typically 99.9% dense.
Minimum Wall Thickness	0.5 mm — Recommended 1.0 mm for structural parts.
Minimum Feature Size	0.4 mm — Small holes may require post-drilling.
Tolerance	+/-0.1 mm — Or +/-0.2% for dimensions over 100 mm.
Support Structure	Required — Supports are removed by CNC or EDM.
Max Build Size	250 x 250 x 325 mm — Larger parts can be split and welded.
Lead Time	From 5 days — Includes support removal and post-processing.

• SLA - Stereolithography (High-detail resin printing with a smooth surface - the standard for figurines, prototypes and consum)
• SLS - Selective Laser Sintering (Durable nylon parts with no supports required - ideal for functional prototypes and batch production)

• FDM - Fused Deposition Modeling (Low-cost, strong and large-format printing with PLA / PETG / ABS / TPU.)

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.
