Technical Details & Test Data
- Notes
Properties reported here are average of a typical batch. The tensile test bars were printed with two shells, 107% material flow, nozzle temperature 260 °C, bed temperature 45 °C, nozzle diameter 0.8 mm, 40 mm/s infill speed, 30 mm/s print speed, and layer height 0.3 mm. The flexural and impact bars were printed in the XY plane, using the normal quality profile in Ultimaker Cura 2.1, an Ultimaker 2+, a 0.4 mm nozzle, 90% infill, 235 °C nozzle temperature, and 70 °C build plate temperature. The values are the average of five white and five black specimens for the flexural and impact test. The Shore hardness D was measured in a 7-mm-thick square printed in the XY plane, using the normal quality profile in Ultimaker Cura 2.5, an Ultimaker 3, a 0.4 mm print core and 100% infill. The electrical properties were measured on a 54-mm-diameter disk with 3 mm thickness printed in the XY plane, using the fine quality profile (0.1 mm layer height) in Ultimaker Cura 3.2.1, an Ultimaker 3, a 0.4 mm print core, and 100% infill.
