Selective Laser Sintering

Benefits

  • No supports required
  • High surface finish and details

Disadvantages

  • ​Limited material options
  • Slower print times

How it works

Selective Laser Sintering (SLS) printers utilize a high-powered laser to sinter powdered polymer together. Once an entire layer has been sintered, the build plate lowers and a fresh layer of powder is deposited and sintered to the previous layers. After parts have been printed, excess powder is removed using compressed air. Leftover powder is mixed with fresh powder and used for the next print.

Additional Considerations

  • SLS machines are expensive to run due to the high powered lasers and expensive machine and material costs.
  • Native material usually only comes in white or grey. However, white prints can be dyed other colors.
  • While material can be recycled, it must be mixed with fresh material at the appropriate ratio.
