PolyCast
$49.99
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. Designed for investment and metal casting.
Filament diameter is 1.75mm.
Comes in one color only – natural.
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.
