PolyCast™ is a filament designed to produce investment patterns for investment casting applications. 3D printing significantly cuts down both the cost and lead time by eliminating the tooling process.


PolyCast™ features Polymaker’s Layer-Free™ technology and Polymaker’s Ash-Free™ technology:

Layer-Free™ – Layer-Free™ technology involves exposing a 3D printed part to an aerosol of micro-sized alcohol droplets, generated by a rapidly vibrating, perforated membrane called the nebulizer. The aerosol will then be adsorbed by the surface of the 3D printed part and render it smooth and layer-free.

Ash-Free™ – Ash-Free™ technology allows Polymaker’s filament which has been designed for investment casting to burn off cleanly without any residue, enabling defect-free metal parts. 3D printing has been used to produce investment casting patterns as it cuts down both the cost and lead time for small-volume production runs.




No Ash – PolyCast™ burns off cleanly without any residue, enabling defect-free metal parts

Low Cost – PolyCast™ is a cost-effective solution, with a lower cost compared to other 3D printing technologies (e.g. SLA/DLP/SLS).

Effortless Post-processing – PolyCast™ can be effortlessly post-processed in the Polysher™ (sold separately) reducing layering and delivering superior surface quality.

Easy-to-print – PolyCast™ is compatible with most 3D printers, printing under similar conditions to PLA with no heated bed or chamber required.

Uncompromised Quality: Polymakers leading quality control process and rigorous in-house testing, ensure reliable printing and consistency across spools and batches.
