PolyMax™ PC-FR is a fire-retardant PC filament (UL94V-0/1.5 mm) displaying excellent strength, toughness and heat resistance whilst also achieving a V0 score in the UL94 flame retardancy test. PolyMax™ PC-FR can reduce the intensity of a fire or slow/stop the spread of fire due to its self-extinguishing characteristic, opening new applications in the automotive, railway and aerospace industries. Like PolyMax™ PC, PolyMax™ PC-FR is produced with Polymakers Nano-reinforcement technology.

Features

• Flame Retardant - PolyMax™ PC-FR displays V0 performance in the UL94 flame retardancy test[1], benefiting applications where respective material approval is required. PolyMax™ PC-FR can reduce the intensity of a fire or slow/stop the spread of fire due to its self-extinguishing characteristics.
• Fantastic Toughness - An excellent choice for engineering applications, Polymaker has introduced its nano reinforcement technology that is featured in all PolyMax™ materials. This boosts the fracture toughness of the FR material and produces a flame-retardant filament that can still perform in demanding applications.
• Heat Resistant - PolyMax™ PC-FR offers better heat resistance than a wide variety of material types, featuring a heat deflection temperature up to 110 ºC (HDT 0.45MPa).
• Improved Printability - PolyMax™ PC-FR has been engineered specifically with compatibility and usability in mind. PolyMax™ PC-FR not only offers excellent properties and print quality, but also improved printability when compared to other PC filaments. Enclosure and 90°C heated bed required; an actively heated chamber is also highly 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 or PVA glue to the build surface to improve adhesion.
• Enclosure: Highly recommended.
• Heated Chamber:
  • Highly recommended, required for some geometries.
  • 90˚C - 100 ˚C required for higher density and larger geometries.
• Cooling Fan:
  • OFF for most printers.
  • LOW FAN speed may be required inside some heated chambers.
• 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.

PC-FR requires a stable and hot printing environment. Before printing we recommend to pre-heat your build plate 20 - 30 minutes before printing. In colder climates a longer pre-heating time may be useful. For users printing without an actively heated chamber, be mindful of the part size and infil density, larger or denser parts will use more material which will result in more residual stresses within your part.

Anealing PC-FR

For the best mechanical performance it is recommended to anneal parts printed in Polymaker™ PC-FR. Annealing is the process of heating up the printed parts at a certain temperature for a certain period of time. The purpose of annealing Polymaker™ PC-FR 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: 1kg
• Material Type: PC-FR
• Density: 1.19 (g/cm3 at 21.5˚C) 

Compatibility

PolyMax™ PC-FR has been engineered with 3D printing in mind however please note this material requires a heated bed and enclosure. We highly recommend printing with an actively heated chamber for the best printing results.

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.
