Collection: PC-PBT Filament

PC-PBT filament blends polycarbonate with PBT for a material that stays tough even in the cold, remaining impact resistant down to around -30°C where standard PC can turn brittle. We stock it in Black, 1.75mm, held locally in Australia.

Why Choose PC-PBT?

The real reason to reach for this over standard PC is cold weather performance. Standard PC gets brittle as temperatures drop, PC-PBT stays tough and impact resistant down to around -30°C, which matters for anything that lives outdoors or in an unheated space.

  • Stays impact resistant down to around -30°C, unlike standard PC
  • Combines PC's strength and heat resistance with PBT's chemical stability
  • High toughness and dimensional stability under load
  • A genuine step up for cold climate and outdoor applications

What Prints Suit PC-PBT Best?

This one earns its keep on parts that face the cold, chemicals, or repeated mechanical stress:

  • Automotive components exposed to cold or vibration
  • Outdoor electrical housings and enclosures
  • Industrial fixtures and tooling
  • Parts exposed to chemicals or solvents

PC-PBT vs Standard PC

Both share PC's strength and heat resistance. The real difference is cold weather toughness. Standard PC is the better choice for maximum heat resistance and optical clarity. PC-PBT is the one to reach for when the part needs to survive genuinely cold conditions without turning brittle.

Printer Compatibility

Our 1.75mm PC-PBT needs an enclosed printer with a heated bed and high nozzle temperatures, the same demanding setup as standard PC. A hardened nozzle is not required for this material, but a stable, enclosed environment is essential to avoid warping.
