Issue Converting SLA/DLP Supports to Solid - Not Connecting to Mesh

Hey everyone!


I've been having an issue since I installed MeshMixer. Whenever I generate supports for a mesh and use the "SLA/DLP" preset, everything works fine at first. However, when I convert those supports to a solid, then none of the supports connect to the mesh, and they even seem to avoid the mesh as if it had a force field around it. It's easiest to show this on the miniatures I'm trying to print, but it happens on every mesh I can import, including the default ones.


I've already tried:

  • Reinstalling MeshMixer 3.5
  • Installing MeshMixer 3.3
  • Installing MeshMixer 3.3 and 3.5 on a different computer (Both are Windows 10)
  • Restarting/Updating my computers
  • Messing with every setting individually
  • Choosing "New Object" and "Replace Existing" when deciding how to convert the supports


Is there something I can do to fix this issue or at least work around it?

Most up to date SLA/DLP slicers handle MM's raw supports just fine. Please check if you really need to convert the raw supports to a solid support.


Making supports solid in Overhangs MM merges the different support elements based on a certain voxel grid which may smooth small stuff as the supports' tips. You might get a better solid result accepting the raw supports, separating them as a separate object and running EDIT/MakeSolid on it with a higher SolidAccuracy and MeshDensity at file size costs.
