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

When printing with PolyMax™ 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
