All testing specimens were printed under the following conditions:

nozzle temperature = 255 °C, printing speed = 60 mm/s, build plate temperature = 100 °C, infill = 100%

All specimens were conditioned at room temperature for 24h prior to testing

Based on 0.4 mm nozzle and Simplify 3D v.3.1. Printing conditions may vary with different nozzle diameters

When printing with PolyLite™ PC it is recommended to use an enclosure. For large part it is recommended to use a heated

chamber.

It is recommended to anneal the printed part right after the printing process to release the residual internal stress.

Annealing settings: 100˚C for 2h
