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.

  • Information

    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 minimizing layer lines.

    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 inhouse testing, ensure reliable printing and consistency across spools and batches.
