Filatech FilaFlexible40 Black filament 500g

Is it for me?

FilaFlexible40 is elastic, flexible and rubber-like material. On the hardness scale, 40D stands for hard rubber. Whether you need a phone cover, an action camera case or wheels for your RC car, the flexible filament is the way to go.

Hard rubber may be a popular material, however, in some situations, it can be less than ideal or even completely unsuitable. Whether you need a phone cover, an action camera case or wheels for your RC car, flexible is the way to go. The flexible filaments are called TPE (ThermoPlastic Elastomer) or TPU (ThermoPlastic Polyurethane). Compare to normal flexible filaments (TPU or TPE based filaments), FilaFlexible40 has higher resilience (more rubbery), better performance in a wide range of temperatures, easier and more stable printing, higher chemical resistance and also UV resistance.

To successfully print with a flexible filament, first, clean the nozzle of previously extruded plastic. Next, you’ll need to empty the hotend of any plastic left inside. Normal unloading will leave some filament inside and flexible filaments will have a very hard time to extrude. So either do a “cold pull”, where you preheat, insert PLA, set the temperature to 85°C, loosen the idler completely and pull the filament out rapidly. Or alternatively, if you have 1.5mm wire around, you can just preheat and push the filament out with the wire. Before you actually load the filament, loosen the extruder (idler) screws a bit. After that, you’re good to go.

Flexible filaments can bond to the bed too much, especially to smooth PEI. To prevent damage we recommend to use glue on the bed as a separator. You can also use the Double-sided Textured PEI Powder-coated Spring Steel Sheet without the glue.
