Push Plastic PC-PBT Engineering Filament – 1.75mm, 1kg

Build tough, durable parts for demanding applications with Push Plastic PC-PBT Engineering Filament. This high-performance blend combines polycarbonate with polybutylene terephthalate to deliver a strong balance of stiffness, toughness, ductility, impact resistance, and chemical resistance.

PC-PBT is designed for functional parts that need to hold up to repeated use, mechanical stress, drops, oils, grease, and demanding shop environments. It is a strong choice for brackets, mounts, fixtures, machine accessories, tool holders, automotive components, CNC-related parts, and other engineering applications where PLA or PETG may not be sufficient.

Why You’ll Like It

• Balanced engineering performance: Combines stiffness with useful ductility for durable functional parts.
• Strong impact resistance: Well suited to parts exposed to drops, knocks, and repeated handling.
• Excellent fatigue performance: A practical option for components that experience repeated stress or movement.
• Chemical resistance: Resists exposure to motor oil, grease, and other common shop contaminants.
• Functional-part focused: Ideal for brackets, mounts, fixtures, tool holders, machine accessories, and automotive components.
• Three practical colors: Available in Black, White, and Orange.

Available Colors

• Black
• White
• Orange

Recommended Print Settings

• Nozzle temperature: 260–290°C
• Bed temperature: 90–110°C
• Nozzle: 0.4mm or larger
• Layer height: 0.16–0.28mm
• Print speed: 30–60mm/s starting range
• Enclosure: Strongly recommended

Drying and Printing Tips

• Dry the filament before printing to improve surface finish, layer bonding, and consistency.
• Use a printer capable of the required nozzle and bed temperatures.
• Print in an enclosed environment to help control warping and improve dimensional stability.
• Prepare the build surface carefully and verify first-layer adhesion before starting a long print.
• Use moderate print speeds when strength and repeatability matter more than cycle time.
• Allow the completed part to cool gradually before removing it from the bed.
