One cycle, start to finish.
Parts go into the front-loading chamber on processing racks. The SFX then runs conditioning, processing, curing and drying in one automated cycle. Consumable loads from Safe-Pour cartridges, with a quick-change recovery cartridge in the machine.
- 01
Conditioning
Parts are conditioned in the chamber to reach the right processing conditions.
- 02
Processing
Vaporized consumable is injected into the chamber and smooths part surfaces under controlled conditions.
- 03
Curing
The consumable is removed from the surface and the surface resolidifies.
- 04
Drying
Parts are dried so no consumable remains in the chamber, ready for use.
Cycle
up to 2 h
One automated cycle, from as-printed to finished.
