Support materials have never been so easy to use. Scaffold is for dedicated support structures, and either peels away easily (in the case of Scaffold Snap) or dissolves away in water. For use in dual extrusion systems.

Hi Ray,

The recommended settings for scaffold soluable are as follows:

  • Print Temperature: 215°C
  • Bed Temperature: From 20°C to 55C ideally, but will cope with bed temperatures as high as 110°C
  • Print Speed: ~50mm/s
  • Support Infill: ~15%
  • Support Angle: 45° & -45° (create a crosshatch pattern)
  • Dense Solid Layers: 3
  • Dense Solid Infill: 90%
  • Upper & Lower Separation Layers: 0
  • X/Y Separation Distance: 1.0mm to 0.50mm depending on the material and how well calibrated your nozzle offset is
  • Support Angle: 46° and up
  • Support Pillar Resolution: 1mm
  • Raft: Yes

You will also want to make sure that you keep the PVA dry i.e always store in a airtight container with silica gel. Also avoid keeping the hotend at an idle temperature when waiting for the other filament to be printing as this can degrade the filament.
