Filament ROSA-PLAST Rosa3D PC‑PBT 1.75 mm 0.5 kg — HT‑UV‑IMPACT, Black

ROSA-PLAST Rosa3D PC‑PBT 1.75 mm 0.5 kg — HT‑UV‑IMPACT, Black is a blended polycarbonate‑polybutylene terephthalate filament formulated for FDM/FFF 3D printers that accept 1.75 mm filament. The HT‑UV‑IMPACT modifier improves heat resistance, ultraviolet stability and impact performance compared with standard PC‑PBT blends. The filament comes on a 0.5 kg spool in a neutral black color intended for functional parts, prototypes and end‑use components that require dimensional stability under elevated temperature and exposure to sunlight.

Advantages

This PC‑PBT filament offers a balance of mechanical strength and toughness suitable for demanding functional parts. Improved heat resistance reduces softening and deformation near heat sources, while enhanced UV stability limits surface degradation and color shift during outdoor use. The HT‑UV‑IMPACT formulation increases impact resistance to reduce brittle failure in mechanical components. The 1.75 mm diameter ensures compatibility with a wide range of desktop and industrial FDM/FFF extruders configured for that size.

Suitable for

• Functional prototypes requiring higher thermal resistance and toughness
• Mechanical components such as hinges, mounts and brackets
• Outdoor parts exposed to sunlight and moderate weathering
• End‑use parts where impact resistance is critical
• FDM/FFF printers and projects compatible with 1.75 mm filament

How to use

Load the 1.75 mm filament into an FDM/FFF printer configured for PC‑PBT blends and set the extruder temperature according to the printer manufacturer's recommendations for PC‑PBT materials. Use a heated build plate and ensure good bed adhesion—options include PEI, glass with adhesive or compatible build surfaces. Print settings such as slower print speed, increased part cooling management, and appropriate retraction values help maintain dimensional accuracy and surface finish. Post‑print annealing can be considered where enhanced thermal stability is required; follow established annealing profiles for PC‑PBT blends if applicable.

Usage recommendations

Store the filament in a dry, cool place and, where possible, use desiccant or vacuum packaging to prevent moisture uptake. For best results, calibrate extrusion multiplier and first‑layer height before printing critical parts, and test small samples to fine‑tune temperature and cooling parameters for your specific printer and application.
