General printing guidelines *

*) Above displayed settings are meant as guidance to find your optimal print settings. These ranges in settings should work for most printers, but please do feel free to experiment outside these ranges if you think it is suitable for your printer. There are a lot of different type of printers, hot-ends and printer offsets that it is extremely difficult to give an overall one-size-fits-all setting.

*) Print temperature 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)

*) Flow rate depends on configuration of hotend and feeder setup, but is increases when printing speed increases (e.g ± 110% for 50mm/s till even 130% for 100mm/s

Hygroscopy

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 without 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. Python Flex is packaged in a vacuum bag with a guaranteed moisture content of less than 0,2% to ensure ideal printing behavior and results directly after opening the spool.

Why a cardboard spool and box?

• FormFutura cardboard spools and boxes are manufactured in the Netherlands we are actively minimizing the total travel distance and which logistically helps us to reduce our carbon footprint even further! 

• Recycling cardboard spools and packaging can easily be arranged via existing paper recycling programs.

• Cardboard is a natural desiccant (drying agent) and the cardboard spool will protect your filament even more against humidity. 

• Many engineering type of filaments require pre-dried at elevated temperatures and cardboard spools can be dried at much higher temperatures than plastic spools due the risk of deformation in plastic spools.

• Cardboard allows us to create spools with a truly unique and sustainable character.
