What is PolyCast ™ used for?

PolyCast ™ has been specially developed for investment casting (also known as lost wax casting) of metal.

What advantages does PolyCast ™ offer for investment casting?

For traditional investment casting, you must first make a metal tool to create wax patterns. The processing usually takes several weeks, the costs are very high. Using 3D printing with PolyCast ™ eliminates the need for these tools.

Another advantage of PolyCast ™ is that you can use 3D printing to create complex geometries that are simply impossible with tools.

In summary, PolyCast is ideal for:

  • Rapid production of small volume metal parts
  • Metal parts with complex geometries

How is PolyCast ™ different from other 3D printed filaments?

PolyCast ™ is the first 3D print filament specifically designed for metal investment casting. To enable this application, we have designed the material to have two main functions:

Superior surface quality
PolyCast ™ can be polished in Polysher ™ (using Polymaker's patented Micro-Droplet Polishing ™ technology), eliminating layers and creating a very smooth part surface. This is crucial for the quality of the metal parts.

Clean burnout
Most polymers leave residues when they decompose - this is a problem during investment casting and can lead to defects in the metal parts. Polymaker has designed the material to completely decompose at T> 600 C and provide a clean mold for casting.

Is PolyCast ™ easy to use?

Using PolyCast ™ is easy. It prints under typical PLA conditions and is compatible with almost any filament-based 3D printer. Polymaker has developed the material to provide excellent printability, dimensional stability and easy removal of the support material.

The printed parts can then be polished in Polysher ™ to significantly improve surface quality. After polishing, the part is ready for use in precision casting.
