Metal 3D printing materials: stainless steel, aluminium, titanium and die steel
All of VEYSEN’s metal 3D printing is done by SLM, and six metals are available now. The tables below give build sizes and mechanical properties so you can compare them against what your part needs.
The six metals
Stainless steel
316L
Corrosion resistant and ductile. A general-purpose stainless steel that also suits parts exposed to moisture.
420 × 420 × 450 mm
Stainless steel
17-4PH
Higher strength and hardness, which heat treatment raises further. It suits mechanical parts and fixtures.
420 × 420 × 450 mm
Aluminium alloy
AlSi10Mg
Lightweight and well suited to thin walls and complex shapes, such as housings and brackets.
420 × 420 × 450 mm
Aluminium alloy · anodizing grade
6061
The choice when the part needs anodizing, which is available on request.
420 × 420 × 450 mm
Die steel
18Ni300
Reaches 54–57 HRC after heat treatment. It suits mold cores, mold inserts and tooling parts that need high strength.
250 × 250 × 280 mm
Titanium alloy
Ti6Al4V (TC4)
Strong, light and corrosion resistant. It suits lightweight structural parts.
250 × 250 × 280 mm

Heat treatment is optional and depends on the application.
A dash (—) means no value is available.
Values are typical data-sheet values for reference. Actual results depend on part geometry and print settings.
Surface and post-processing
Supports and support marks are removed from every metal part, and some layer lines will still be visible. Heat treatment, CNC finishing of critical surfaces, thread tapping, polishing and sandblasting are available on request, as is anodizing for 6061.
