Sintering Refractory Ballast - Al2O3
Use: Refractory ballast for firing Filamet™ materials in a vacuum. May be used alone or combined with Powdered Graphite.
Place the print in this refractory, ensuring the entire print and all surfaces are completely covered and any protruding areas are fully supported. The print must be fully surrounded by the refractory. Complete firing instructions
Stainless Steel 316L and High Carbon Iron Filamet™ require an oxygen-free environment. Copper and Bronze Filamet™ may be fired in an open environment. In this case, use Magic Black Powder to shield the print from oxygen. See chart below.
