HIPS Filament – Strong, Versatile and Ideal as a Support for ABS

HIPS (High Impact Polystyrene) is a durable and lightweight 3D printing filament that serves two valuable roles: as a structural material for functional parts and as a dissolvable support material for ABS and other high-temperature filaments. Its strength, surface finish, and easy post-processing make it a popular choice in both engineering and design.

When paired with ABS in a dual-extrusion 3D printer, HIPS acts as a support material that dissolves cleanly in d-Limonene, leaving behind a smooth surface with minimal effort. This makes it ideal for printing complex geometries, enclosures, and overhangs that require reliable support structures.

As a primary filament, HIPS is easy to sand, prime, and paint — perfect for creating prototypes, models, and casings with a professional finish. It prints best in heated, enclosed 3D printers to prevent warping and ensure consistent layer bonding.

Bilby3D supplies high-quality HIPS filaments that are dimensionally accurate and consistent, tested to perform with both Raise3D and other open-material printers. Available in multiple colours and spool sizes for both industrial and educational use.
