Using the PolyMaker PolyFlex TPU90 filament is easy. First, set your printer according to the recommended settings. The nozzle temperature should be between 210˚C and 230˚C, and the printing speed can be from 30mm/s to 60mm/s. Keep the bed temperature between 25˚C and 60˚C, and use a glass or BuilTak® bed surface. Make sure the cooling fan is turned on. Before using, dry the filament at 70˚C for 8 hours to get the best results. As for maintenance, store the filament in a dry place to prevent moisture absorption. If you notice any issues with the print quality, check the printer settings again as they may vary depending on your printer model and nozzle diameter.
