Product Description

3D printer extruder retrofit kit for dual-extruder direct-drive machines, such as the Flashforge Creator Pro, QiDi Tech, Powerspec Ultra, Malyan M180, and Makerbot Replicator 2X. 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.


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, please read our blog post about it.

This kit requires you to disassemble your printer’s extruder and reinstall this upgrade. Detailed instructions on this process can be found on our support page.
