Enables swift and efficient printing while ensuring safety and reliability, perfect for dental 3D printing and food-contact tools

  • High printing speed: Printing speed up to 300 mm/s enables users to save time while maintaining exceptional printing accuracy

​​

  • Superior Printability: Excellent bed adhesion, minimal warping, and extremely fast print speeds at 265-275°C.

  • Accessible: Delivers high-performance benefits without needing ultra-premium 3D printers.

  • Precision Manufacturing: Available in 1.75mm and 2.85mm diameters with strict tolerances.

Characteristics and Benefits of PEN-HF in FDM Applications:

 Exceptional temperature resistance and barrier properties for demanding environments.

 

 Suitable for applications requiring autoclave, gmma, and EtO sterilization compatibility.​

 

 FDA food-contact approved, complies with RoHS2 and REACH

 

 ​With optimized printing conditions, enables water-tight and low-vacuum suitability without post-

 processing. ​

The FDM process creates parts with a layered structure, causing mechanical properties to be anisotropic based on print orientation.*1

  • Flat XY orientation: predominant mechanical strength from infill​

  • Side YZ orientation: predominant mechanical strength from walls​

  • Upright Z orientation: interlayer adhesion strength.

*1 The values reported in TDS represent the average from a batch of 10 test specimens. For tensile, flexural, and impact properties of the 3D printed test specimens were produced using a 0.4 mm nozzle, 100% infill, print speed of 60mm/s, a nozzle temperature of 270°C and a build plate temperature of 80°C. FLXR Engineering is continuously working on expanding the TDS data

*2 The chemical resistance of PEN is evaluated by the following test method:

    Specimens are immersed in the chemical (liquid) at 23°C for 30 days.

    Ranking definition: A: weight change <1%, tensile strength retained >95%;

                                  B: weight change between 1~10%, tensile strength retained >75%;

                                  C: weight change >10%, tensile strength retained <75%;

                                  D: swelled or dissolved within 120 hours.
