Is filament supplied on a spool?

FootPrint3D supplies filament per spool of 2.3 kilograms. All you have to do is 1) place the spool on the spool holder and 2) properly attach the filament to the 3D printer.

How many pairs of insoles can I print with one spool?

One spool contains 2.3 kg of filament. On average, 23 pairs of insoles can be printed with this.

Are adjustments possible with this filament?

The filament we supply is thermoplastically deformable. This means that the custom-made insoles can be adjusted under heat. It is of course also possible to add elements afterwards. Special glue is needed that has good adhesion to TPU.

How can I store filament?

Filament is hydrophilic, which means that it extracts moisture from the ambient air. Moist filament is more uneven, breaks faster and has a negative impact on the quality of the custom-made insoles. We therefore advise you to prevent the filament from coming into contact with moisture. Therefore, store the filament in a dry room with minor temperature fluctuations. Leave the filament in the vacuum package for as long as possible before use. You can heat moist filament in an oven intended for this purpose.
