PolyCast (3KG Spool)

The First 3D Printing Filament Designed for Metal Casting!

What is PolyCast™ used for?

PolyCast™ is designed specifically for investment casting (also known as lost-wax casting) of metal. You can use it with 3D printing to replace the wax patterns used in industrial investment casting processes.

What are the benefits of PolyCast™ for investment casting?

In traditional investment casting, you need to first make a metal tool to produce wax patterns. The tooling typically takes several weeks at least, with cost starting at thousands of dollars.   By using 3D printing and PolyCast™, you can eliminate the need for tooling, which saves you time and money greatly.

Another benefit of PolyCast™ is that you can use 3D printing to create complex geometries that are simply not possible by tooling.

In summary PolyCast is great for:

  • Rapid-production of small-volume metal parts

  • Metal parts with complex geometries

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

PolyCast™ is the first 3D printing filament designed specifically for metal investment casting.  To make this application possible, we have enabled the material with two key features:

Superior Surface Quality:

PolyCast™ can be polished in the Polysher™ (via Polymaker’s patented Micro-Droplet Polishing™ technology), eliminating the layers from filament-based printing processes and resulting in a very smooth part surface. This is critical to ensure the quality of metal parts.

Clean Burnout:

Most polymers leave residues when they decompose – this is a problem for investment casting and can lead to defects on the metal parts.  We have engineered the material to ensure that it decomposes completely at T > 600 C, leaving a clean mold ready for casting.

Is PolyCast™ easy to use?

The use of PolyCast™ is quite simple.  It prints under typical PLA conditions and is compatible with just about any filament-based 3D printer. Polymaker has engineered the material to feature excellent printability, dimensional stability, and easy removal of support.

The printed parts can then be polished in the Polysher™, to dramatically improve the surface quality.  Once polished the part is ready to be used in investment casting processes.
