Increase speed quickly and accurately. Yes, it is possible. The FIBERFLEX 40D filament is the best proof of this. With this flexible material, which has a hardness of 40D on the Shore scale, you can print at a speed of 45 mm/s without worrying about print quality. Furthermore, you will find that printing with flexible filaments doesn't have to be difficult at all. Feeding it to the extruder is extremely easy, and the printed layers adhere well to each other. The prints you create exhibit properties such as high impact resistance, low-temperature resistance, as well as chemical resistance and abrasion resistance. This makes FIBERFLEX 40D suitable for both private and professional use. Applications include: rubber machine parts (seals, elements that need to be frequently bent), gadgets or parts thereof (phone cases and housings, watch bands, straps for heart rate monitors, pedometers), connecting elements (flexible hinges), toys or parts thereof (tires, rubber figures), and jewelry (bracelets).
