Polymaker PolyCast Filament – 1.75mm Castable Filament for Investment Casting
Polymaker PolyCast is a specialised castable 3D printing filament engineered specifically for investment casting and lost-wax style manufacturing processes. Designed to produce precise casting patterns, this material enables users to create complex geometries directly from a 3D printer, eliminating the need for traditional wax tooling.
Built for foundries, jewellery makers, and engineering applications, PolyCast combines easy printability with clean burnout performance, making it an efficient and reliable solution for producing high-quality metal casting patterns.
Key Benefits
Designed for Investment Casting
PolyCast is formulated to produce accurate casting patterns that can be used directly in investment casting workflows, helping streamline production and reduce preparation time.
Clean Burnout with Minimal Residue
The material features ash-free technology that allows printed patterns to burn out cleanly during the casting process, leaving extremely low residue levels that help prevent defects in final metal parts.
Eliminates Traditional Tooling Requirements
By 3D printing casting patterns directly, PolyCast reduces the need for mould tooling and wax injection, saving time and lowering production costs.
Easy to Print with PLA-Like Settings
This material is designed for excellent printability using common PLA-style settings, making it accessible on most FDM/FFF 3D printers.
Smoothable Surface for Better Casting Results
Printed parts can be smoothed using isopropyl alcohol to reduce visible layer lines, improving the surface quality of the final cast metal component.
