Nobufil PCx Filament – High-performance filament made from recycled industrial polycarbonate (made in Austria)

Nobufil PC filament (PCx) is a high-quality 3D printing material made from recycled industrial polycarbonate waste sourced in Europe.

PCx (modified polycarbonate) is a polymer blend based on PC. Thanks to a specially developed formulation, PCx is significantly easier to print than conventional polycarbonate – while offering excellent mechanical properties and high temperature stability. These PC filament properties make PCx the ideal technical filament for functional parts, prototypes, and heat-resistant components.

Thanks to its special formula, PCx prints with minimal warping and is compatible with many common desktop 3D printers (both enclosed and open-frame). The properties of PCx offer a perfect balance of strength, toughness, and easy processing – ideal for demanding 3D printing applications.

For even higher stiffness: Our PCx CF variant adds carbon fibers to the same sustainable base, delivering exceptional rigidity (3500 MPa flexural modulus) while maintaining heat resistance up to 113 °C – perfect for lightweight, load-bearing parts.

FAQ – Frequently asked questions about PC filament

What is PCx filament?

PCx is Nobufil's product name for a modified polycarbonate blend (PC), made from recycled industrial plastic from Europe. Unlike standard PC, which tends to warp heavily and requires extreme printing conditions, Nobufil PCx is optimized for minimal warping and easier processing – while maintaining high strength and heat resistance up to 112 °C (113 °C for PCx CF). A true high-performance filament for functional parts, prototypes, and heat-resistant applications.

Is PC filament the strongest 3D printing filament?

It depends on the property. PC filament is among the toughest and most impact-resistant filaments available – it is used for bullet-resistant glass, for example. In terms of tensile strength, our PCx reaches 61 MPa, which is very high but slightly below some filled nylons. In heat resistance (HDT), PCx achieves 112 °C – far above PLA, PETG, or ABS. In impact strength (unnotched 45 kJ/m²), PCx outperforms most standard filaments. Overall, PC filament ranks among the most powerful engineering materials for 3D printing.

Is PC filament toxic?

PC filament itself is considered non-toxic when printing, as long as the room is well ventilated. Unlike ABS, PC does not release styrene. However, printing at high temperatures (approx. 285 °C) can release fine particles and small amounts of volatile organic compounds. We therefore recommend printing in a well-ventilated area or using an enclosure with a filter. For occasional use in a workshop with window ventilation, PCx is considered safe.

Is PCx filament easy to print?

Standard PC filament is known for severe warping and often requires a heated chamber. Nobufil PCx is modified and significantly easier to print. It shows minimal warping on well-tuned printers – an enclosure is recommended but not mandatory. Using a textured PEI sheet, 285 °C nozzle, and 110 °C bed gives good results. It remains an engineering filament, but much more accessible than pure PC.

Do I need to dry PCx filament before printing?

Yes. PC filament is hygroscopic – it absorbs moisture from the air. Wet PC prints poorly (bubbles, stringing, weak parts). Dry PCx before printing (e.g., 80 °C for 4–6 hours in a filament dryer or oven) and store it in an airtight box with desiccant. Best results come from printing directly from a dry box.

Is your PCx filament really made from recycled material?

Yes. All Nobufil 3D printer filaments are made from high-quality recycled industrial plastic waste – sourced exclusively from Europe. We stand for sustainable high-performance filament without compromising on mechanical properties.

What is the difference between PCx and PCx CF?

PCx – Unreinforced PC filament, very tough (45 kJ/m² impact strength), 61 MPa tensile strength, 112 °C HDT. Ideal for parts requiring high strength and impact resistance.
PCx CF – Carbon-fiber reinforced PC filament, much stiffer (3500 MPa flexural modulus), 56 MPa tensile strength, 113 °C HDT. Perfect for lightweight, rigid, dimensionally stable parts. Requires a hardened nozzle.

Can I order larger quantities of your PC filament for my business?

Absolutely. For B2B orders or custom material requests, write to us at: office@nobufil.com. We are happy to discuss bulk pricing and new developments.
