PolyCast™

Features Polymaker's Layer-Free™ technology and Ash-Free™ technology

The Specialty family provides unique filaments from Polymaker to unlock new 3D printing applications. 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.

 

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.

Polymaker PolyCast

Technology

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


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™ 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.
