  • Features

    This filament's soft elasticity, especially combined with the custom nature of 3D printing, make it ideal for costumes, cell phone cases, covers, grips, and thin sturdy membranes. When using hexagonal infill you can even create objects that are stiffer along one axis orientation, while the other axes remain soft and squishy. Since NinjaFlex is softer and bends more easily, it needs to be printed with the Flexystruder Tool Head. NinjaFlex's high elasticity also requires it to be printed at lower speeds and at a larger layer height than standard filaments.

    Advanced users can utilize its ability to bind to ABS when using a FlexyDually Tool Head to make prosthetics, live hinges, wearables, and other projects requiring flexible, complex 3D printed items.
