Fiberlogy Fiberflex 40D - Red filament 850g


Is it for me?

Fast and precise. Yes, it’s possible. FIBERFLEX 40D is the best proof of this. With this flexible material with Shore hardness of D40 you can print at the speed of 45mm/s without worrying about the quality of the print. What’s more, thanks to FIBERFLEX 40D you will discover that printing with flexible filaments doesn’t have to be difficult. Feeding it to the extruder will be extremely easy and the printed layers will stick together well.

Your prints will have such properties as: high impact resistance, low temperature resistance, chemical and abrasion resistance. Because of that FIBERFLEX 40D can be used for both amateur and professional applications.

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.
