Printing Notes

Polycarbonate has a 123 °C heat deflection temperature and a 115 °C continuous use rating. It is the material for parts that live near heat.

It is extremely hygroscopic. Twelve hours of drying at 80 °C is a minimum, not a suggestion, and it should print straight from a dry box.

Klipper's pressure advance does most of the ooze control on a Trident, so short fast retraction beats long slow retraction here.

As a self-built machine the Trident's chamber temperature is whatever you have built it to hold, so check it before starting a high-temperature print rather than assuming.

Slicer: OrcaSlicer / SuperSlicer (Klipper). Dry the filament at 80 °C / ≥ 12 h before a long print. Every figure above assumes dry filament.

Troubleshooting

Loud popping and steam from the nozzle. The filament is wet. Stop, dry for twelve hours at 80 °C, and print from a dry box.

Parts warping badly or pulling the bed sheet up. PC shrinks hard. Use a brim, keep the chamber hot, and consider a glue-stick release layer so it comes off without damaging the sheet.

Cloudy or milky finish instead of translucent. Moisture again, or too much cooling. Turn the fan off completely.
