PolyCast™ is specifically to print patterns for metal investment casting. PolyCast™ features Ash-Free™ technology typically leaving an ash residue of 0.003% when burnt out at temperatures >600°C. For quick design iteration, metal prototyping or unique one-off casts, PolyCast™ offers a solution. This 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. 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. Nozzle Temperature: 190˚C – 220˚C Printing Speed: 40mm/s – 60mm/s Bed Temperature: 25˚C – 70˚C Bed Surface: Glass with glue, blue tape Cooling Fan: ON Based on 0.4 mm nozzle and Simplify 3D v.3.1. Printing conditions may vary with different printers and nozzle diameters Other: It is highly recommended to use the PolyBox™ when printing with PolyCast™ and to store it in the resealable bag. *****(Advisable to store the filament into dry cabinet after use)***** Authorize Reseller and Distributor for Polymaker products Since 2017.
