Developed by the inventor of Ninjaflex
Drop-in 3D printer extruder retrofit kit for i3-style printers like the Wanhao Duplicator i3. Print with flexible materials, higher resolution, and fewer failures. Also prints ABS and PLA better than your stock extruder.
3D printer extruder
Retrofit kit for single-extruder direct-drive machines, such as the Wanhao Duplicator i3 (and PLUS), Monoprice Maker Select, or Makerbot rep2 (see pulldown menu). The Flexion extruder will allow full-speed printing of flexible filaments and improved accuracy printing with PLA and ABS. The precision machined components allow your printer to push on filament harder, achieve high pressure in the nozzle, and control of feed rates very closely. The self-cleaning drive will keep your long prints from failing due to a clogged drive. Works will with Ninjaflex, Filaflex, flexible PLA, TPU, TPE ultra-flexible filament down to 50 Shore A, and all the standard rigid filaments like ABS and PLA.
Replaces the Makerbot Replicator 2 extruder, pictured to the left. You will need to remove or replace the plastic plate above the extruder.
*Does not include stepper motor.
The Flexion Extruder uses a high-stiffness lever to compress the filament. The compression is controlled with a cam and an adjust screw, rather than the traditional spring. This allows more tension and more precise control of the tension. To learn more about the benefits and drawbacks of this system.
This kit requires you to disassemble your printer’s extruder and reinstall this upgrade.
