2.85mm FPE Black Filament 0.50kg Shore 65D

Material

FPE (Flexible PolyEster) is a mixture of a rigid polymer and a soft polymer. The exact relation of these components define the exact hardness. 45D hardness can be compared with the hardness of a sport shoe sole.

Apart from its flexibility FPE has some interesting characteristics:
- good layer-to-layer adhesion
- relative high temperature resistance
- resistant to a wide variety of liquids

Printing Guidelines

Print settings of FPE are different from "standard" materials like PLA. Most printers are optimized for stiff materials, so in general you have to reduce the printspeed and make sure that the flexible filament cannot buckle. Application in Bowden fed printers (like the Ultimaker) is also possible, but make sure you lower the print speed drastically. We get good results when using the values shown in the table below.

Use the above values as a starting point, optimal values for your specific printer may vary from the values shown above, depending on e.g. nozzle diameter, printing speed and layer height. For large objects, a raise in bed temperature may be necessary.

Packaging

All FPE filament will be shipped on a plastic spool, to prevent entangling. The spool itself will be shrinkwrapped to protect against dust and dirt. To make it complete: we add silica gel drying agent to fight against moisture.

Spool dimensions are shown in the table below:
