PC Settings for UltiMaker Method X

Temperature Settings

Start with the nozzle at 285°C and the bed at 110°C. If you see poor layer adhesion, increase the nozzle temperature by 5°C increments. If you experience stringing, decrease the nozzle temperature by 5°C. For the first layer, you can increase the bed temperature by 5°C for better adhesion, then let it drop back to 110°C for subsequent layers.

The PC filament has a recommended nozzle temperature range of 260-310°C and a bed temperature range of 100-120°C. The UltiMaker Method X supports nozzle temperatures up to 300°C and bed temperatures up to 110°C, which fully covers the recommended range for this filament.

Speed & Quality

The UltiMaker Method X supports high-speed printing at up to 500 mm/s. For PC, we recommend 20-40 mm/s for general printing. Start with the lower end for quality-critical prints and increase for draft prints. Always print the first layer at 25-50% of your normal speed for better adhesion.

For quality-critical prints like miniatures or display pieces, reduce the speed to 20 mm/s and use a 0.12-0.16mm layer height. For draft or rapid prototyping, you can push the speed to 40 mm/s with a 0.24-0.28mm layer height. The standard 0.2mm layer height at 30 mm/s provides the best balance of speed and quality for most prints.

Bed Adhesion

Polycarbonate needs very high bed temperatures and excellent adhesion. Use a PEI sheet at maximum bed temperature. Apply glue stick as a release agent (PC can bond too strongly). A brim is essential. Consider Magigoo PC specialty adhesive for best results.

Common Issues with PC on UltiMaker Method X

Here are the most common problems you may encounter when printing PC on the UltiMaker Method X, along with proven solutions:

• Severe warping/cracking: Ensure enclosure is sealed, increase bed temp to max, reduce fan to 0%, and slow print speed
• Nozzle clogging: Verify you have an all-metal hotend, increase temperature, and check for moisture in filament
• Layer splitting: Increase nozzle temperature, slow down, and improve enclosure insulation
• Yellowing: Normal at very high temperatures; reduce temperature slightly if discoloration is excessive

Tips for Best Results

Follow these expert tips to get the best possible prints with PC on your UltiMaker Method X:

• PC is the most demanding common filament to print -- make sure your setup is fully prepared
• An all-metal hotend is mandatory; PTFE-lined hotends will degrade at PC temperatures
• Seal your enclosure as thoroughly as possible for the best results
• Use glue stick as a release agent -- PC can bond so strongly to PEI that it damages the sheet
• If you are new to high-temp printing, try ABS or ASA first before attempting polycarbonate

Support Settings

For prints requiring supports with PC, use tree supports for easier removal and less scarring. Set a 0.15-0.2mm Z-distance between support and model. If you have a dual-extruder setup, consider PVA (for PLA/PETG) or HIPS (for ABS) as dedicated water/solvent-soluble support material.
