Selective Laser Melting – SLM processes with marhellabs

Your contact for Rapid Prototyping with Selective Laser Melting (SLM)

In the process of Selective Laser Melting, a metal powder is applied as a very thin layer on a carrier plate. The 3D CAD model is melted into the powder with a laser. By lowering the carrier plate gradually, new and very refined powder coatings are applied. They are melted selectively and connected firmly to one another. This is how a tailor-made 3D component is created using the SLM method.

Advantages of SLM 3D printing

  • Selection of different materials for your area of application
  • High building depth
  • Optimal print quality
  • Mechanical resistance
  • High strength
  • Good mechanical properties
  • Thermal conductivity
  • Machine processing
  • Low weight thanks to topologically optimized components
  • Internal structures for lightweight construction concepts
  • Good corrosion resistance

Selective Laser Melting – Areas of application

Using aluminum for SLM, it is possible to manufacture functional prototypes, functional parts and serial parts. Sectors like lightweight construction, aerospace, engine and gearbox construction are using Selctive Laser Melting.
3D printing with steel creates serial parts and special tools. They are used in mechanical engineering, casting mold production and motor sport.
For surgical instruments and medical implants, 3D prints made of stainless steel and titanium are best suited. They stand out due to their mechanical properties as well as their very high strength.
