Custom Polycarbonate 3D Printing Services

Polycarbonate (PC) is the strongest thermoplastic you can 3D print. With virtually unbreakable impact resistance, transparency, and heat tolerance up to 130°C, polycarbonate is the choice for safety-critical, high-stress, and optically clear applications.

Why Choose Polycarbonate for Your Parts?

Polycarbonate is the same material used in bulletproof glass, safety goggles, and riot shields. Its impact resistance is 30x greater than acrylic and 250x greater than glass. When your parts absolutely cannot fail under mechanical stress, polycarbonate is the answer.

Beyond impact resistance, PC brings high heat tolerance (130°C), natural flame retardancy, and the ability to print in translucent/clear for light-pipe and optical applications. It's the most demanding FDM material to print — requiring very high temperatures and enclosed chambers — but the performance justifies it for critical applications.

Advantages
  • Highest impact resistance of any printable thermoplastic
  • Excellent heat resistance — continuous use up to 130°C
  • Naturally flame retardant — UL94 V-2 rated
  • Available in transparent/translucent for optical applications
  • Good UV resistance for moderate outdoor exposure
  • High tensile and flexural strength
  • Dimensionally stable under load and temperature
Considerations
  • Highest printing temperature — requires industrial-grade equipment
  • More expensive than ABS, PETG, and ASA
  • Prone to warping on large parts — requires careful setup
  • Poor chemical resistance to some solvents and fuels
  • Moisture-sensitive filament — must be dried before printing

Common Applications for 3D Printed Polycarbonate

Safety & Protective Components
Machine guards, protective shields, impact-resistant covers, and safety enclosures for industrial equipment and machinery.
High-Temperature Housings
Enclosures for electronics, sensors, and components that generate significant heat. PC handles 130°C where ABS and PETG would soften.
Light Pipes & Optical Parts
LED light guides, lens covers, indicator windows, and translucent panels. Clear PC transmits light while providing impact protection.
Flame-Retardant Components
Parts in environments with fire safety requirements — electrical enclosures, panel components, and equipment near heat sources.
Automotive Under-Hood Parts
Components exposed to engine heat, vibration, and mechanical stress. PC handles the harsh under-hood environment better than most polymers.
Structural Load-Bearing Parts
Brackets, mounts, and structural components where failure isn't an option. PC's combination of strength and impact resistance provides a safety margin.

Frequently Asked Questions

FDM-printed PC is translucent rather than optically clear due to layer lines. Light transmits through, making it excellent for light pipes and indicator windows, but you won't get window-glass clarity. For fully transparent parts, our SLA clear resin is a better option.
PC filament costs more than ABS or PETG, and it requires higher printing temperatures which increases energy costs slightly. Expect parts to cost 20–40% more than equivalent ABS parts. However, for applications requiring extreme impact resistance or high heat tolerance, no other material matches PC's performance.
PC has good UV resistance — better than ABS but not quite as good as ASA. For moderate outdoor exposure, it performs well. For maximum UV longevity in direct sun, ASA is still the better choice. PC excels outdoors where impact resistance is the primary concern.
PC requires nozzle temperatures around 270–310°C and bed temperatures of 110–130°C, plus an enclosed heated chamber. It's prone to warping and layer delamination without proper setup. Our industrial printers and controlled environment are specifically designed for high-temp materials like PC.
