What is PolyCast™ Used For?

PolyCast™ is a 3D printing filament developed specifically for investment casting (also known as lost-wax casting) of metal parts.

Advantages of PolyCast™ for Investment Casting

• No tooling required: Traditional casting requires expensive metal tools to create wax patterns. PolyCast™ eliminates this step, saving both time and cost.
• Complex geometries: 3D printing allows for shapes and designs that are impossible with traditional tooling.

PolyCast™ is ideal for:

• Rapid production of small-volume metal parts
• Metal parts with intricate designs

How PolyCast™ is Different from Other Filaments

Superior Surface Quality

PolyCast™ can be polished in the Polysher™ using Polymaker’s patented Micro-Droplet Polishing™ technology. This creates smooth, layer-free surfaces essential for high-quality metal casting.

Clean Burnout

Unlike most polymers, PolyCast™ fully decomposes without leaving residues. This ensures defect-free metal parts during the casting process.

Ease of Use

• Prints under PLA-like conditions, compatible with most filament-based 3D printers.
• Offers excellent printability, dimensional stability, and easy support removal.
• Printed parts can be polished in Polysher™ to significantly improve surface quality and prepare them for precision casting.
