Description

DMLS is an advanced powdered bed fusion (PBF) technique where a re-coater blade or roller evenly distributes powdered metal across a substrate. A high-precision laser then selectively melts the powder layer by layer to build up the desired part. This method is highly regarded in the automotive and aerospace industries for producing high-performance metal components with exceptional precision and strength.

Materials Available

  • Aluminium Alloy (AlSiMg)
  • Aluminum
  • CO-CR Alloy (MPT)
  • Chromium Bronze (QCR 1)
  • Cobalt Chrome
  • Copper
  • Die Steel (MS1)
  • Inconel
  • Maraging Steel
  • NI Base Superalloy (In 718)
  • SS316
  • SS316 L
  • Titanium
  • Titanium Alloy (TC4)

Technical Details

  • Mechanical Properties: High strength and durability comparable to traditionally manufactured metal parts.
  • Surface Finish: Rough; typically requires post-processing for smoothness.
  • Dimensional Accuracy: High, within ±0.1mm.
  • Max Build Size: Typically up to 250 x 250 x 325mm.
  • Speed of Production: Moderate to slow.

Advantages

  • Can be used to print parts with lattice structures and topology optimized designs, which can reduce weight while maintaining strength.
  • Does not require support structures, which allows for more complex geometries and dimensional accuracy.
  • Excellent material properties suitable for functional parts.
