Product Alert

Separate accessory recommended for Lulzbot users!

  • Semiflex is so flexible it requires either the Flexystruder or FlexyDually Tool Head for optimal printing performance.

  • Print Surface Recommendation:

    NInjaFlex adheres exceedingly well to PEI print surface. We strongly recommend applying PVA glue (white school glue) directly on the print surface using a glue stick (such as Elmer's® brand) before printing to ensure easy part removal.

From Ninjaflex website:
