PEN-Natural 

Approved up to 24-hour contact with skin and tissue and, where applicable, indirect with blood.

  • Engineering-Grade Performance: Combines chemical resistance, heat stability, and low extractable potential.

  • Superior Printability: Excellent bed adhesion, minimal warping, and fast print speeds at 270~285°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, utilizing processes similar to biocompatible tubing.

Characteristics and Benefits of PEN-Natural in FDM Applications:

  •  Exceptional chemical resistance and barrier properties for demanding environments.
  •  Suitable for applications requiring autoclave, gmma, and EtO sterilization compatibility.
  •  FDA food-contact approved; meets USP 88 Class VI and USP 87 for bio-inertness
  • With optimized printing conditions, enables water-tight and low-vacuum suitability without post-processing.

Printing Orientation:

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
