3D printing of metals is suitable for the creation of functional prototypes where high mechanical loads are expected or very high temperature resistance is required. Parts produced by the SLM method from metal powders can be further modified by conventional methods such as machining, grinding, polishing, welding or heat treatment.

The metal 3D printing process using the SLM method has an advantage over other 3D methods (e.g. SLS) in the overall melting of the powder into a liquid state, which guarantees excellent print homogeneity and better mechanical properties compared to other methods. The SLM method achieves a reduction in porosity and better control over the crystal structure of the material used.

3D metal printing is today a generally accepted part of engineering production. If you are interested in learning more about the quality of our printing, or would like to see specific laboratory tests, please contact us.

3D printing of metals from atomized metal alloys

We primarily print parts from stainless steel 316L (1.4404). Proven mechanical properties, impact work, porosity in the longitudinal and transverse direction and achievable roughness parameters can be found here.

At the customer's request, we are also able to print in larger volumes from other powder metals certified by Trumpf and Renishaw:

  • high-strength steel (maraging steel - M300)
  • aluminum alloy (AlSi10Mg)
  • titanium alloy (Ti6Al4V)
  • stainless steel (316L)

Characteristics of powdered metals (mechanical, physical and chemical properties) are available on the manufacturer's website. As part of engineering production, we also offer post-processing in the form of machining, milling or heat treatment for further refinement.

If you are interested in 3D printing from powder metal or for consultations on this topic, do not hesitate to contact us.
