PC-PBT Gray

Description

3D Printing Filament PC-PBT New Formulation – High Stability for Open-Frame Printers

Recommended Printing Parameters

• Printing Temperature: 250–260 °C

• Filament Drying: 90 °C

• Heated Chamber: not required (OFF)

• Nozzle Type: brass

• Pre-extrusion Material Drying: 100 °C for at least 4 hours

Material Characteristics

The new formulation PC-PBT is a polycarbonate and polybutylene terephthalate blend designed for professional 3D printing. It is a very rigid material with excellent high-temperature resistance and dimensional stability, even in challenging environmental conditions. A key innovation is its printability on open-frame machines, thanks to low warping and excellent interlayer adhesion.

Main Technical Properties

• Tensile Modulus: 2600 MPa

• Tensile Strength: 60 MPa

• Elongation at Break: 3.6%

• Notched Impact Strength (23°C): 5.0 kJ/m²

• Vicat Softening Point (50 N): 130 °C

• HDT at 0.45 MPa: 107 °C

• HDT at 1.81 MPa: 80 °C

• Density: 1.25 g/cm³

Features and Benefits

• High structural rigidity

• Excellent chemical resistance to oils, solvents, fuels

• Heat-resistant and long-term stable behavior

• Compatibility with printers without an enclosed chamber

• Good surface quality of printed parts

• PFAS-free

• Non-abrasive: compatible with brass nozzles

Recommended Applications

The new formulation PC-PBT is ideal for:

• Mechanical and functional components for industrial use

• Automotive components and technical environments exposed to heat and chemicals

• Brackets, supports, and jigs for production or assembly

• Electronic enclosures or parts requiring dimensional stability

⚠️ Not suitable for contact with food, potable water, or for medical uses or in the production of toys.
