Selective Laser Melting produces full-density metal parts directly from CAD in stainless steel, titanium, aluminium and tool steel. The benchmark process for complex metal geometries impossible to machine or cast.
SLM uses a high-power fibre laser to selectively melt and fuse metal powder layer by layer in an inert argon atmosphere. Parts emerge at near-theoretical density with mechanical properties equivalent to or exceeding wrought material. Complex internal channels, lattice structures and topology-optimised geometries impossible to machine are printed routinely.
✓ Full-Density Metal Parts
99.9% density. Mechanical properties match or exceed wrought material, suitable for structural, load-bearing and fatigue-critical applications.
✓ Complex Internal Geometries
Conformal cooling channels, internal lattices, undercuts and topology-optimised structures that cannot be produced by subtractive methods.
✓ Multiple Certified Alloys
316L stainless, Ti-6Al-4V titanium, AlSi10Mg aluminium and 17-4PH stainless. Aerospace and medical-grade certified powder stocks.
✓ No Tooling Lead Time
From CAD to finished metal part in days, bypassing casting patterns, tooling fabrication and minimum order constraints.

"I would highly recommend Pratik at 3D Printing — with his analytical mind he helped re-engineer a component for an electric scooter. The final design was cost effective, strong and an exact fit."
"Can't speak more highly of this Company. They overcame many difficulties through their tenacity and patience. I highly recommend this company for any 3D prototyping, design or development of your idea."
"Great service, quick turnaround — I needed parts scanned, a couple of design changes and printed. All done quickly, efficiently and A+ quality. Definitely recommend the team at 3D Prototyping."
"It was a pleasure dealing with 3D Prototyping. They are professional and their customer service is excellent. I would recommend these guys any time over any other players in this industry."
"This Company is good, efficient and easy to deal with. Their advice and knowledge around materials really helped us get what we needed. Great service provided. We will certainly use this company again."

Selective Laser Melting uses a high-power fibre laser to selectively melt metal powder in an inert argon atmosphere, building parts layer by layer at 20-50 micron resolution. Parts emerge at up to 99.9% theoretical density with mechanical properties matching wrought material.
We print 316L stainless steel, Ti-6Al-4V titanium, AlSi10Mg aluminium, 17-4PH stainless, Inconel 625/718 and tool steel (H13/M2). All powder stocks are aerospace and medical-grade certified.
All SLM parts require stress relief heat treatment and support removal. Options include CNC machining of critical surfaces, shot peening, electropolishing, HIP for highest density, and full material certification testing.
Minimum wall thickness is 0.3mm (recommended 0.5mm for structural integrity). Our engineers perform a full DfAM review on every metal print file before quoting, flagging support, distortion and geometry risks.
