Direct Metal Laser Sintering (DMLS) / Selective Laser Melting (SLM)

What are the benefits of DMLS / SLM?

Benefit #1

Parts weight optimization - topology

Benefit #2

Geometric structures production that can be made only by 3D printing - e.g. cooling channels for tools (conformal channels)

Benefit #3

Difficult-to-cut materials processing - e.g. nickel alloys

Benefit #4

Meeting high-quality requirements for advanced industries - aviation, medicine

Materials

Aluminum alloys - Product description

These are alloys based on the ALSi10Mg and AlSi7Mg0.6 from casting. 3D printed parts made of this material are often used as functional prototypes and serial parts in industries such as machinery, aviation or automotive.

Costs and Lead Time

What affects costs and lead time in DMLS/SLM

  • Part volume
  • Used material
  • Used parameters (e.g. layer thickness)
  • Bottom brackets - check other technologies without support
  • Production series size
  • Applied postprocessing - more information in postprocessing
  • Choosing express execution options

DMLS/SLM design guidelines

For the DMLS / SLM technology, we recommend the following rules:

Minimum bore diameter 2 mm

Minimum wall thickness from 0.8 mm depending on the geometry

For geometries above 35 deg, the manufacturing is possible without a support structure

Provide access to areas with support to remove it

The positioning pins should be at least 2mm thick / diameter
