3D metal printing explained

3D metal printing, also known as selective laser sintering (SLS) or selective laser melting (SLM), is an additive manufacturing technique that allows the rapid manufacturing of prototypes directly from 3D CAD files. Broadly speaking, 3d metal printing frees the designer from previous manufacturing constraints, opening a new world of possibilities for your wished designs.

The 3d metal printing of designs is a combination of powder material and laser power in a layer by layer basis:

  1. The metallic powder is applied as a thin layer (30 to 80microns thickness)
  2. The Laser melts the powder at the required locations
  3. The process is repeated until the height of the part is reached
