"Do I have to use a hardened nozzle on my printer to print Filaflex Conductive?"

NO, it is not necessary. You can print with whatever nozzle you have without a problem, but if you print a lot with this material, we advise you to use a hardened nozzle to avoid wear.


"Is it safe to print with Filaflex Conductive filament or can it end up damaging my printer?"

Yes, it is totally safe and will not damage your printer, but to keep it in good condition we recommend that you clean the nozzle very well when you finish printing with this filament. This way you will remove any sediment that may have remained in the hotend. You can use another material such as PET-G to clean the nozzle. Read more about hotend maintenance and repair here.


"What material is added to make the filament conductive?"

We use a special formulation containing lamp black, which makes the TPU filament conductive.


"Does Filaflex Conductive lose its flexibility after printing?"

Not at all. Filaflex Conductive does not lose its elasticity after printing. The finish of this material is a flexible and electrically conductive part. Its mechanical and conductive properties remain intact. You can see in this vIdeo how the filament retains its elasticity once it has been printed (black part of the piece).


"What is the Shore hardness of Filaflex Conductive filament?"

It has a 92A Shore hardness, which makes it compatible to be printed on most printers, even bowden type extrusion printers. If you want to learn more about Shore hardness, don't miss this post.


"What resistance does the conductive filament present?"

To learn about the resistivity of Conductive Filaflex (also known as specific resistance), we recommend consulting with our team. In order to determine if the material will fulfill the functions in a specific project, it's important to note that the resistance changes depending on its printing.

In order to successfully use Filaflex Conductive TPU filament in electronic applications, the electrical resistance of the circuit must be considered and keep in mind that this filament is designed for low current applications.


"What can I do if I have adhesion problems between layers?"

Being a material with high carbon loading, heat dissipates very fast and therefore the adhesion of the part may be weakened depending on its geometry. The best solution is to adjust the printing parameters. Print at a slow speed, between 20-25 mm/s, and at high temperature, between 240-255ºC, eliminating the layer fan in all layers, to avoid heat dissipation being too fast.
