Open a world of possibilities, limited only by your imagination. NinjaFlex, a cutting-edge filament for 3D printers, is a specially formulated thermoplastic polyurethane (TPU) that produces flexible prints with elastic properties. Patent pending technology allows for smooth feeding and clean, high-quality printed parts.



NinjaFlex flexible filament leads the industry thanks to its superior flexibility and longevity compared to non-polyurethane materials. Its consistency in diameter and ovality (roundness) outpaces other polyurethane materials. Made from a specially formulated thermoplastic polyurethane (TPU) material, this patented technology boasts a low-tack, easy-to-feed texture. The result is uniquely flexible, strong prints ideal for direct-drive extruders. Suggested Applications: Seals, gaskets, plugs, leveling feet, protective applications.

  •  Shore Hardness = 85A
  •  Truly flexible (no fill or layer manipulation required to achieve performance)
  •  660% elongation allows for repeated movement and impact without wear or cracking
  •  Polyurethane composition allows for excellent vibration reduction
  •  Patented low friction exterior allows for smooth feeding
  •  Abrasion resistance 20% better than ABS and 68% better than PLA
  •  Consistent diameter and material properties providing reliable, high quality prints
  •  Chemical resistant to many materials, including naphtha, ASTM Oils #1-3, petroleum and freon
  •  Adheres to all standard build platforms without glue or tape
  •  REACH and RoHS 2002/95/EC Directive compliant

Extruder Temperature:  225‚C 235‚C Platform Temperature: Room temperature 40‚C Glue and/ or blue painters tape is suggested if not using a heated bed. Print Speed: Top and bottom layers: 10-20 mm/ sec (600-1200 mm/ min) Infill speeds: 15-35 mm/ sec (900-2100 mm/ min) Layer 2+ use cooling fan if available. Tips & Tricks Safety: We recommend printing in a well-ventilated area for use with all of our materials. TPEs are capable of releasing small amounts of fumes at high temperatures. Finishing parts: Best results are achieved using a dremel or a hot knife for smoothing rough surfaces. It is also tolerant to cutting and light drilling as required for an application. Connecting printed parts: Welding is the best option. Plastic welders, soldering irons, wood burners or heat guns are ideal. NinjaFlex will also bond to other plastics using the same method. Injection molding: NinjaFlex is available in pellet form and is useable for injection molding in addition to pellet extrusion. Bridging: NinjaFlex is not ideal for bridging, though it can handle some small areas in unsupported applications. Water resistance: Occasional contact with water will have no adverse effect on NinjaFlex, but long-term exposure will degrade the material to the point in which its elastic properties will be reduced. UV Resistance: NinjaFlex is not recommended for long-term continuous outdoor use as it has no UV stabilizer. However, it does boast higher UV performance over ABS & PLA . Short term usage is suitable, with an estimated 4-6 months before seeing any degradation.
