Sample PrusaSlicer profiles

I’ve bundled up a working set of PrusaSlicer profiles for various nozzle size and speed settings. Each custom profile contains my initials (RLG) and the date last updated to avoid confusion.


I’ve worked with each of these profiles, but make no warranty as to their suitability for use on your printer. Be careful if you have not calibrated your current nozzle and Live-Z settings. I have done some basic prints using each of these settings, but they are all “experimental” and not guaranteed perfect. Use at your own risk!


These notes are based on my experiences with the Prusa i3 Mk3 printer. If you are using a different printer, please verify the hardware details are same. These pages may be a bit rough as I revise them and add new material. Please check back regularly for updates.

You can download my PrusaSlicer profiles as of December 21, 2019 here.


I’ve updated the version date to match the last configuration modification date rather than the last date this page was edited.

To use these profiles:

  1. Download the config bundle archive named

  2. Extract the config bundle archive. It will contain a file named PrusaSlicer_config_bundle_<date>.ini.

  3. Open PrusaSlicer and select File->Load Config Bundle.

  4. Select the extracted .ini file and select OK.

PrusaSlicer will display an indicator that the custom profiles have been successfully imported:

Check your Printer Settings, Filament Settings and Print Settings to confirm that the custom profiles have been loaded.

You’ll get an error about missing post-processing scripts. You can remove these under Print Settings->Output options->Post-processing scripts. I’ve got a couple of python scripts set up to bump the fan at slower speeds and rename files on the fly that I’ll write up eventually.
