PC (PolyCarbonate) is a popular 3D printing material for engineering and industrial applications, offering vastly superior mechanical and thermal properties when compared to many other engineering plastics.
PolyMax™ PC takes things a step further, offering significantly better toughness than other PC materials.
- Nano-reinforcement technology results in superior toughness.
- Excellent stiffness and rigidity.
- Excellent tensile strength and heat resistance.
- Fantastic flow and inter-layer adhesion.
- Good chemical resistance.
- Based off Covestro's Makrolon® resins, PolyMax™ PC has been engineered and optimized specifically for 3D printing.
Further expanding the applications of 3D printing towards more demanding use cases, PolyMax™ PC is stronger, stiffer and tougher than many other engineering materials. PolyMax ™ PC is not only an exceptional material for engineering and manufacturing applications, but has found popular use among educators and hobbyists.
3D printing PC has commonly required high nozzle and bed temperatures (up to 320°C / 120°C). PolyMax™ PC is formulated with usability in mind; resulting in a product which combines the desirable mechanical performance of PC with more accessible printing requirements. PolyMax™ PC can be printed without an enclosure and is compatible with most ABS-capable 3D printers. With very similar printing characteristics to ABS an enclosure is required when printing any reasonably sized parts.

Industry Leading Quality Control
PolyMax™ PC like all other Polymaker materials is manufactured using state-of-the-art polymer processing technologies and equipment. Polymakers rigorous minimum 8 quality control processes ensure industrial standards of reliability for a consistent customer experience.
Tolerance: Polymakers custom developed extrusion, control and monitoring solutions to ensure filament tolerance and roundness meet Polymakers strict quality standards.
Reliable Mechanical, Colouring & Printing Properties: Every batch of filament products are tested to ensure all quality specs (melt flow, softening point, mechanical, diameter, round-ness) are met.
Drying & Vacuum Sealing: Before packaging, all Polymaker filaments are dried to a moisture level of < 0.1% to ensure the best printing quality and are vacuum sealed to protect the filament from moisture. All vacuum packaged products are left for 24 hours before boxing to ensure they are leak-free.
3kg Spool: PolyMax™ PC is wound on Polymakers 3kg spools.
Resealable Bag: PolyMax™ PC is packaged in a vacuum sealed resealable bag to ensure your filament is moisture free. Like all other PC filaments, PolyMax™ PC is hygroscopic so we recommend using this bag for filament storage.

It is recommended to anneal the printed part right after the printing process to release the residual internal stress.
Storage & Drying
Before packaging, PolyMax™ PC is dried to ensure the best printing quality and filaments are vacuum sealed to protect the filament from moisture. When not in use PolyMax™ PC should be stored away from sunlight in the packaged resealable bag.
Like other PC filaments, PolyMax™ PC is susceptible to absorbing moisture from the air which can subsequently effect the quality and mechanical properties of the final prints. We recommend storing PolyMax™ PC in the PolyBox™ or a dry cabinet during printing to prevent moisture absorption which will lower the quality of the print. The PolyBox™ keeps the filament at dry conditions (relative humidity of 15% or less).
If you hear popping sounds and notice that the surface quality of your print is uneven or the color is not consistent, this is a likely indicator that the filament has absorbed too much moisture. Spools of PolyMax™ PC can be dried in a preheated convection oven at 80˚C for up to 8 hours. Results may vary depending on the accuracy of your oven so please be conservative. For more information about filament drying please read our user guide.

The typical values presented in Polymakers data sheet are intended for reference and comparison purposes only. Due to the nature of 3D printing they should not be used for design specifications or quality control purposes.
PolyMax™ PC has been engineered with compatibility in mind to print excellently on a wide range of professional 3D printers. This material requires a heated bed and we recommend printing with an enclosure or heated chamber for sizeable or thin models.
Of course with thousands of unique 3d printer models on the market, we can't guarantee each filament type will work with every 3D printer.
Q: Polymaker manufacture many different PC filaments, which one should I purchase?
A: PolyLite™ PC and PolyMax™ PC are the best choices for users who are interested in 3D printing strong PolyCarbonate parts that don’t have a specialized requirement. These two materials are easier to print when compared to PC filaments from other brands. PolyLite™ PC offers transparency and the best value for general purpose printing and PolyMax™ PC is our most popular PC filament, with boosted toughness and additional benefits in printability. Aside from variances in price and mechanical performance, Polymaker™ PC-ABS, Polymaker™ PC-PBT and PolyMax™ PC-FR offer unique solutions for industrial applications, with excellent mechanical performance and slightly higher printing requirements. Polymaker™ PC-PBT for example offers excellent toughness at subzero temperatures whereas PolyMax™ PC-FR offers the best flame retardancy. To discuss which material is the best for your printer and application, contact us today!
Q: Is this product the same as Polymaker PC-Max™?
A: Yes! Polymaker launched a new naming system to simplify the ever growing product range for customers. During this change the name PC-Max™ was updated as PolyMax™ PC. PolyMax™ is a family of advanced 3D printing filaments produced with Polymaker’s Nano-reinforcement technology.
Q: Does Polymakers Nano-reinforcement technology impact printability?
A: The nano-reinforcement of PolyMax™ PC is NOT a fiber reinforcement, so customers can confidently print this material with a standard brass nozzle. The good mechanical strength of PolyMax™ PC is achieved with no compromise in printing quality or usability.
Q: Can PC be printed at large scales without warping?
A: A stable high temperature environment is required to print larger PC parts without warping and whether a part is susceptible to warping will vary on how the residual stress releases within the parts geometry. Most users print PC with the heated bed set to 100˚C and an enclosure to passively heat the surrounding environment; this effectively reduces internal stress which cause PC to warp or crack. To guarantee that PC can be printed at any size without warping, 3D printing with a professionally designed heated chamber is required.
Q: Is PolyMax™ PC flame retardant?
A: PolyMax™ PC is classified with a UL94-V2 rating. For applications requiring the best classification we recommend choosing PolyMax™ PC-FR which is a flame retardant PC filament (UL94V-0/1.5 mm).
Q: What support materials can I use with this product?
A: Polymaker’s PolyDissolve™ S2 filament is the recommended support filament for PolyMax™ PC. If your 3D printer is not equipped for multi-material, self-support can be used.
