Direct Metal Laser Sintering (DMLS) and Selective Laser Melting (SLM) are powder bed fusion technologies that use a high-powered fibre laser to fuse metal powder particles layer by layer into fully dense, structural metal components.
A high-power fibre laser melts and fuses metal powder particle by particle — building fully dense structural metal parts from the ground up.
Your STL, STEP, or OBJ file is reviewed by our engineers for metal-specific DfAM (Design for Additive Manufacturing) considerations — wall thickness, support strategy, thermal management, and build orientation are all optimised before printing begins.
The build chamber is flooded with inert argon or nitrogen gas to prevent oxidation. The selected metal alloy powder (15–45 µm particle size) is loaded and the build platform is heated to the material-specific pre-heat temperature.
A 200–1000W fibre laser scans the powder bed according to the sliced cross-section, fully melting and fusing metal particles at temperatures exceeding 1600 °C. Each layer is typically 20–80 µm thick. The build platform descends after each layer and fresh powder is rolled over.
After printing, parts undergo a mandatory stress relief cycle inside the build chamber at elevated temperature. This relieves residual thermal stresses introduced during the rapid heating and cooling of the laser fusion process, preventing warping and cracking on support removal.
Parts are separated from the build plate via EDM wire cutting or band saw. Metal support structures are removed by hand tools, CNC machining, or EDM depending on geometry. All residual powder is removed by bead blasting.
Parts are inspected dimensionally and visually against the 3D model. Optional post-processing (CNC machining, polishing, anodising, PVD coating, or heat treatment) is applied before final quality sign-off and shipment.
All alloys delivered in natural metal finish. CNC machining, polishing, and surface coating available on request.
Low-carbon austenitic stainless. Excellent corrosion resistance, good ductility, and broad chemical compatibility.
Lightweight aluminium-silicon-magnesium alloy. High strength-to-weight ratio, good thermal conductivity, and thin-wall capability.
Precipitation-hardened nickel-chromium superalloy with exceptional strength retention up to 700 °C. The go-to alloy for extreme environments.
Exceptional strength-to-weight, excellent biocompatibility, and outstanding corrosion resistance. 60% lighter than steel.
High-strength cobalt-based superalloy with excellent wear resistance, corrosion resistance, and biocompatibility. Ideal for high-temperature and medical applications.
Low-carbon iron-nickel steel known for exceptional toughness, hardness, and dimensional stability after heat treatment. Excellent for tooling and aerospace applications.
Martensitic stainless steel combining high strength, good corrosion resistance, and excellent mechanical properties after heat treatment. Widely used in industrial and aerospace sectors.
Commercially pure titanium offering excellent corrosion resistance, lightweight performance, and outstanding biocompatibility. Suitable for medical and chemical processing applications.
Metal additive manufacturing compresses timelines, eliminates tooling, and unlocks geometries impossible with any other manufacturing method.
Eliminate die-casting, forging, and CNC fixture costs. Go from digital file to production metal part without a single piece of tooling — dramatically reducing upfront investment for low-to-medium volume production.
Internal conformal cooling channels, topology-optimised lattices, undercuts, and organic shapes are all achievable in a single print — without assembly or additional machining steps.
DMLS/SLM produces parts with >99% density and mechanical properties that match or exceed cast equivalents. Fully dense microstructure with fine grain size yields excellent fatigue resistance.
Metal powder bed fusion uses only the material required to build the part — generating up to 80% less material waste compared to CNC subtractive machining from billet, particularly valuable for expensive superalloys.
From digital file to finished metal part in as few as 5–7 business days. No casting lead time, no tooling manufacture, no minimum order quantity constraints.
Ti6Al4V, CP Titanium, and CoCrW are all ISO 10993 biocompatible — enabling direct production of patient-specific surgical implants, dental prosthetics, and orthopaedic components.
