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.

### Features

- **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 heated bed or chamber required.
- **Complex Geometry** - By 3D printing with PolyCast, you can manufacture metal parts with complex geometries that are simply not possible through tooling, casting or subtractive manufacturing.
- **Optimized for support** - Polymaker have engineered PolyCast™ to print with supports that can easily break away from your parts and once your model is polished there is no scar left on the surface.
- **Uncompromised Quality** - Polymakers leading quality control process and rigorous in-house testing, and rigorous in-house ensure reliable printing and consistency across spools and batches.
