Polymaker PolyMax PC 3D Printing Filament, 1.75mm, Grey, 750g

Polymaker PolyMax PC is a high-performance polycarbonate 3D printing filament engineered for demanding professional applications. This 1.75mm grey filament offers a superior balance of mechanical strength, toughness, and thermal resistance, making it a reliable choice for creating durable functional parts and complex engineering prototypes. Designed for consistent extrusion, it ensures high-quality results on compatible FDM and FFF 3D printers.

Advantages

The primary advantage of PolyMax PC lies in its exceptional structural integrity and heat resistance, which allow printed components to maintain their shape and performance under significant stress. By utilizing this material, users can produce parts that are not only robust but also exhibit excellent dimensional stability. The filament is specifically formulated to minimize the common challenges associated with printing polycarbonate, providing a smoother workflow for engineers and designers who require reliable end-use parts.

Suitable for

• Functional engineering prototypes
• End-use mechanical components
• Parts requiring high heat resistance
• Durable industrial models

This filament may not be suitable for users with entry-level 3D printers that lack a heated build plate or the ability to reach high extrusion temperatures. Additionally, it is not recommended for applications where extreme chemical resistance is the primary requirement, as polycarbonate may be sensitive to certain solvents.

Key specifications

• Material: Polycarbonate (PC)
• Diameter: 1.75 mm
• Weight: 750 g
• Color: Grey
• Printing Temperature: 250˚C - 270˚C
• Bed Temperature: 90˚C - 105˚C

How to use

To achieve optimal results, ensure your 3D printer is equipped with a heated bed and a capable hotend. Use a high-quality surface adhesive, such as Magigoo PC, to ensure proper bed adhesion during the print and easy removal once the plate has cooled. For direct drive extruders, use a retraction distance of 1mm at 20mm/s, and for indirect drive systems, use 3mm at 40mm/s. Keep the cooling fan turned off during the printing process to maintain layer bonding.

What to consider before purchase

• Ensure your printer hardware supports high-temperature printing up to 270˚C.
• Verify that your printer has a heated bed capable of reaching at least 90˚C.
• Consider the need for an enclosure to maintain ambient temperature and prevent warping.
• Check if your printer is compatible with 1.75mm diameter filament.

Usage recommendations

For enhanced mechanical properties and the release of internal stresses, it is recommended to anneal your printed parts at 90˚C for 2 hours. If the filament has been exposed to humidity, dry it at 75˚C for 12 hours prior to use to ensure consistent print quality.
