Python Flex Print Settings
These settings are recommended by Formfutura and are meant as a starting point to help find your optimal print settings. They should work for most 3D printers; however, you may need to experiment outside these ranges. If you find settings that work better with your printer, feel free to let us know and we will be happy to post them.
Nozzle Size: 0.30mm or larger
Print Temp: ± 220 - 250° C
*Python Flex print temp depends on printing speed and wall thickness (e.g. ± 220 - 230° C for single wall objects with no infill at 50mm/s and ± 245 - 255° C for high infilled objects at 100mm/s)
Bed Temp: ± 0 - 60° C
Print Speed: Medium-Fast
Fan Speed: 50-100%
Flow Rate: ± 110 - 130%
*Flow rate depends on configuration of hot end and feeder setup, but is increases when printing speed increases (e.g ± 110% for 50mm/s till even 130% for 100mm/s)
Retraction: Yes, ± 1-5mm
Print Surface: Glass or Kapton Tape
Formfutura Notes: Python Flex is a very hygroscopic material and will attract and hold water molecules from the surrounding environment. When opened and exposed to humidity too long this can have a negative effect on the printing behavior and quality of the filament. It is therefore strongly recommended to immediately remove the spool from the printer after printing and store it in a vacuum bag or airtight container with silica.
When the filament is too wet it is recommended to dry Python Flex in an oven or filament drying machine at 65c. Drying time depends on how long the filament has been exposed to humidity.
