PolyMax™ PC is an engineering PC filament combining excellent strength, toughness, heat resistance and printing quality. It outperforms many other choices of PC while still printing at a relatively low printing temperature. With a HDT up to 114°C (0.45MPa) it is capable of operating in demanding environments where impact resistance, heat resistance and vibrations occur. Features Best-in-class Toughness - PolyMax™ PC is an engineered PC filament combining best in class toughness & mechanical strength to deliver outstanding performance in a wide range of demanding applications. These outstanding mechanical properties are achieved through the implementation of Polymakers Nano-reinforcement technology which increases toughness and durability, enabling PolyMax™ PC to outperform ABS, ASA, PETG and PLA under a wide range of mechanical tests. Heat Resistant - PolyMax™ PC offers better heat resistance than a wide variety of material types, with a heat deflection temperature up to 114ºC (0.45 MPa). Improved Printability - PolyMax™ PC has been engineered specifically with compatibility and usability in mind. PolyMax™ PC not only offers excellent properties and print quality, but also benefits in printability when compared to other PC filaments. With a lower extrusion temperature (250 - 270˚C), PolyMax™ PC is an accessible PC filament that can be printed on a wider range of 3D printers. 90°C+ heated bed required, enclosure recommended. Uncompromised Quality - Polymakers leading quality control process and rigorous in-house testing ensure reliable printing and consistency across spools and batches. Printing Settings Nozzle Temperature: 250°C - 270°C Build Plate Temperature: 90°C - 105°C Build Surface Material: Works well with most build surfaces i.e Glass, BuildTak® etc Rigid build plates recommended compared to magnetic flex plates. Build Surface Treatment: Apply Magigoo PC. Enclosure: Recommended. Heated Chamber: Highly recommended, required for some geometries. 70˚C+ may be required for higher density and larger geometries. Cooling Fan: OFF for better strength. LOW FAN speed may be required for printers with active chamber heating. Printing Speed: 30 mm/s - 50 mm/s Retraction: The ideal retraction settings vary from printer to printer and depend on the hot end. The following settings have been a good starting point for many machines. Direct Drive: Retraction distance of 1mm with retraction speed of 20mm/s Bowden: Retraction distance of 3mm with retraction speed of 40mm/s Recommended Support Material: Self-support. The above are printing recommendations based on 0.4 mm nozzle. Please note ideal printing conditions may vary depending on your 3D printer setup. For high speed 3D printers, make sure to increase your extrusion temperature in order to use higher printing speeds. PolyCarbonate filaments including PolyMax™ PC benefit from a hot environment. When printing larger or higher density models it can be beneficial to pre-heat your build plate 20 - 30 minutes before printing. In colder climates a longer pre-heating time may be useful. Anealing PC-FR For the best mechanical performance it is recommended to anneal parts printed in PolyMax™ PC. Annealing is the process of heating up the printed parts at a certain temperature for a certain period of time. The purpose of annealing PolyMax™ PC is to release the internal stress which accumulates during the printing process. If not annealed soon after the printing process, internal stress can create micro cracks over time and weaken the part. Annealing Settings - 90˚C for 2 hours. Specifications Net Weight: 3kg Material Type: Tough PC Density: 1.19 (g/cm3 at 21.5˚C) Compatibility 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. Slicer experience and setting adjustment is always required to get the most out of a material. Before jumping into an ambitious project we always recommend printing some known calibration tests to build or make adjustments to the filament profile.
