RE: [rp-ml] Cleaning internal cooling channels of SLS parts

Air and pipe cleaners for internal features is what seems to work best for
us. We use a low pressure air wand, a few small dental type tools, and pipe
cleaners for cleaning off the walls.

  Hi all,

  We are running a Sinterstation SLS machine with the Laserform ST-100
powder material that is working well.
  Cleaning the parts in their brittle green state prior to infiltration is
always a cautious job. Therefore I was wondering if somebody could give me
some best practices and recommendations for cleaning (removal of loose
powder) small and/or 3D holes like internal cooling channels etc. since we
often experience difficulties with this features.
  Thanks in advance!
