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.
