Filament Specification:

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.

#: third party testing by:

*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.
