Push Plastic PC-PBT Engineering Filament | 1.75mm | 10kg

The Engineering Blend Built for Production. 10kg. No Compromises.

PC-PBT isn't a single material — it's an engineering compound. By combining the high-impact strength and structural rigidity of Polycarbonate with the chemical resistance and ductility of Polybutylene Terephthalate, PC-PBT achieves a balance that neither material reaches alone. The result is a filament built for real industrial demands: parts that hold up under impact, survive repeated stress cycles, and don't degrade when exposed to motor oil, grease, and other harsh chemicals.

Push Plastic's PC-PBT comes on a 10kg (22lbs) bulk spool — designed for production environments, large-scale manufacturing tasks, and engineering teams who need a continuous, reliable material supply without the interruption of constant spool changes.

Material Performance Breakdown:

• Stiffness and Ductility — an uncommon combination in a single material. PC-PBT holds its shape under load while absorbing impact without catastrophic fracture — critical for components that need to flex before they fail
• Drop Impact Performance — excellent structural integrity under sudden impact, making it reliable for parts subject to rough handling, drops, or dynamic loading in the field
• Fatigue Resistance — designed to withstand repetitive motion and stress cycles without material breakdown, extending the service life of printed components in high-cycle applications
• Chemical Resistance — high resistance to motor oil, grease, and industrial fluids, maintaining both mechanical properties and surface appearance in harsh operating environments

Built for engineers and manufacturers working in demanding conditions — perfect for:

• Automotive components, underhood parts, and fluid-contact housings requiring chemical resistance
• Industrial tooling, jigs, and fixtures subjected to repeated mechanical stress
• Enclosures and protective covers for machinery operating in oily or chemically active environments
• High-cycle mechanical components — cams, clips, hinges, and snap-fit assemblies
• Transportation and logistics hardware requiring drop impact reliability
• Electronics and electrical housings requiring both rigidity and resilience
• Production runs where 10kg bulk spooling reduces changeover time and material cost per part

Printer Compatibility: Compatible with most 1.75mm FDM 3D printers capable of printing engineering-grade materials. An enclosure is recommended for best results with PC-blend filaments.
