Metal 3D Printing Using Laser Technologies (SLM and DED)

Our facility offers two advanced laser-based technologies for additive manufacturing of metal components:

  • Selective Laser Melting (SLM) – a powder-bed fusion method where fine metal powder is selectively melted layer by layer using a laser beam. This technology is ideal for producing highly detailed, fully dense parts from materials such as titanium alloys, aluminum, tool steels, and stainless steels.
  • Directed Energy Deposition (DED) – a method that uses metal wire as feedstock, which is melted by a focused laser during deposition. DED is suitable for fast fabrication, part repair, and the production of larger or hybrid components. We operate the Meltio M600 system for this technology.

Both technologies are widely used in aerospace, automotive, and general engineering applications, enabling flexible production of functional metal parts tailored to customer requirements.

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.

Metal 3D Printing from Wire Feedstock (DED – Directed Energy Deposition)

The Meltio M600 system enables additive manufacturing of metal components by directly melting metal wire using a high-power laser. This technology allows printing from technically pure metals and alloys with high density and excellent mechanical properties.

We primarily print with stainless steel 316L and can provide verified mechanical property data, detailed microstructural analysis, and evaluation of interlayer bonding quality.

Upon customer request, we can also print using other industrial-grade metal wires compatible with Meltio technology, such as:

  • Tool steels (e.g., H11)
  • Carbon steels (e.g., ER70-S)
  • Titanium alloys (e.g., Ti6Al4V)
  • Nickel-based alloys (e.g., Inconel 718)
  • Copper and aluminum alloys (depending on availability in the required diameter)

Material characteristics such as chemical composition, elongation, and tensile strength are available from the respective wire manufacturers.

We also offer post-processing services, including machining, blasting, tumbling, and heat treatments (such as annealing or HIP), to achieve the desired final properties.

Equipment used for 3D metal printing

Professional 3D printers Renishaw AM400 and Trumpf TruPrint 1000 are used for manufacturing metal components from laser-melted metal powder using SLM (Selective Laser Melting) technology. These printers are among the most advanced of their kind, as evidenced by the high quality of the printed parts.

We also use the Meltio M600 system, which operates on LMD (Laser Metal Deposition) technology with metal wire feed, further expanding our capabilities in metal additive manufacturing.
