Prusament PC Blend Slicer Settings & Tuning Guide

This page provides recommended baseline settings and physical tuning guidelines for Prusament PC Blend. These settings have been verified through thermal analysis and test prints on both direct drive and Bowden extrusion architectures.

Parameter Recommended Value
Nozzle Temperature 265-275 °C
Heated Bed Temperature 110-115 °C
Flow Rate / Extrusion Multiplier 96%
Base Printing Speed 30-50 mm/s
Direct Drive Retraction 1.2-1.6 mm @ 25-35 mm/s
Bowden Tube Retraction 4.5-5.5 mm @ 40-50 mm/s
Optimal Bed Preparation Smooth PEI with PVA Glue Stick
Filament Drying Recommendation Dry at 110 °C for 12 hours before printing

Step-by-Step Calibration Sequence for Prusament PC Blend

To achieve the best results on your specific 3D printer model, perform the following steps in order using the parameters above as your starting baseline:

  1. Temperature Tower: Run a temperature tower from the minimum to maximum recommended temperatures. Look for the bridging quality, overhang crispness, and layer adhesion. For Prusament PC Blend, the sweet spot typically sits right in the middle.
  2. Retraction Calibration: Prusament PC Blend can exhibit minor stringing if retraction distance is too low, or clogging if too high. Start with 1.2-1.6 mm on a direct drive extruder, or 4.5-5.5 mm on a Bowden setup. Adjust in 0.1 mm increments.
  3. Flow Rate Fine-Tuning: Print a single-wall hollow cube to measure the actual extruded wall thickness. Compare it against your slicer settings and adjust your flow rate (currently set at 96%) accordingly.

Unique Handling Details

Unlike basic generic Polycarbonate filaments, Prusament PC Blend utilizes a refined manufacturing process to ensure consistent spool diameter. To prevent crystallization issues or thermal creep, ensure your heat break cooling fan is clean and running at full speed. When printing with high bed temperatures like 110-115°C, allow the print bed to heat for 5 minutes prior to printing to ensure the build surface reaches a stable temperature.

Disclaimer: Slicing profiles depend heavily on your specific machine configuration, ambient room temperature, and local humidity. Always start with conservative speeds and monitor the initial layers of your prints.

Frequently Asked Questions

What should I do if Prusament PC Blend is not sticking to the print bed?
First, clean your print surface thoroughly with 91% Isopropyl Alcohol (IPA) to remove finger oils. For Prusament PC Blend, we recommend Smooth PEI with PVA Glue Stick. If you are still experiencing lifting, reduce your initial layer speed to 15 mm/s and increase the bed temperature by 5°C.
Do I need to dry this filament before printing?
Yes, even brand-new spools can absorb moisture during shipping. We recommend drying Prusament PC Blend at 110°C for 12 hours in a dedicated filament dryer or food dehydrator to prevent bubbling, popping sounds during extrusion, and brittle layers.
What is the recommended cooling fan speed?
For ABS, ASA, and Nylon, keep the cooling fan turned off completely (0%) or at a maximum of 10-15% for bridges to prevent rapid cooling which causes severe warping and poor layer adhesion.
