Metal 3D printing by Selective Laser Melting (SLM) builds fully dense metal parts layer by layer directly from a 3D file, with no mold and no tooling cost. It is the practical route for geometries that cutting and molding cannot reach – conformal cooling channels, lattice and micro-channel internals, consolidated assemblies – and for low volumes where a mold would never pay for itself.
Specification (Core Advantages)
- Process: Selective Laser Melting (SLM) on multi-laser production systems
- Build envelope up to 350 x 400 x 400 mm, plus a small-format cell (Ø100 x 100 mm) for micro and precision parts
- Relative density above 99.9%
- Mating and critical surfaces CNC-finished to ±0.05 mm
- Tool and special steels: 18Ni300 / 1.2709 maraging, M789, H13, SUS 420J2, 17-4PH, 4130, and high-thermal-conductivity mold steels
- Other materials: stainless 316L, aluminium AlSi10Mg and 6061, aerospace-grade Ti-6Al-4V, Inconel 718, pure copper, pure tungsten
- No tooling required: from 3D file to finished metal part in days, not weeks
- Economical from a single piece up to a few hundred: prototypes, spares, customised tooling
- Post-processing available: heat treatment and CNC finishing of critical features
Product Content
SLM uses a high-power fibre laser to selectively melt fine metal powder, one thin layer at a time, inside an inert gas chamber. Because the part is grown rather than cut away, geometry is close to free: cooling channels can follow the contour of a mold cavity, a cold plate can carry a lattice or micro-channel core, and a bracket can be reduced to only the material its load path actually needs.

Typical Applications
- Mold and die: inserts with conformal cooling, venting, or both, to shorten cycle time and reduce warpage
- Precision engineering: fixtures, jigs and tooling components
- Thermal management: pure-copper cold plates with lattice or micro-channel internals
- Aerospace and defence: lightweight brackets and structural components
- Semiconductor equipment components
- Automotive, motorcycle and bicycle performance parts
- Medical and veterinary: bone plates, fixation components and surgical planning models
- Consumer electronics and 3C: functional prototypes and small complex parts
