Polymaker PolyCast Filament for Metal Casting (Lost-PLA), 1.75 mm, 0.75 kg

Print a pattern, then cast it in aluminum, bronze, silver or another metal. PolyCast is made for investment casting: you print the part, cover it in casting plaster, and burn the plastic out in a kiln so molten metal can take its place. No tooling or rubber molds needed.

• Made for investment casting (also called lost-PLA casting).
• Burns out cleanly, according to Polymaker.
• Prints on standard FDM printers.
• Natural color, 1.75 mm, 0.75 kg spool.

Metal casting safety: molten aluminum and bronze cause severe burns, and they can explode on contact with water or damp molds. Work outdoors on dry ground, keep plaster molds completely dry, and wear a full face shield, leather foundry gloves, natural-fiber long sleeves (no synthetics) and leather boots. Burnout makes smoke, so vent your kiln well.
