Sample Slic3r Prusa Edition profiles


These notes apply to 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.

I’ve bundled up a working set of Slic3r Prusa Edition profiles for various nozzle sizes for conveninece. 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!

You can download my Slic3r Prusa Edition profiles as of Nov 08, 2018 here. To use these profiles:

  1. Download the config bundle archive named
  2. Extract the config bundle archive. It will contain a file named Slic3r_config_bundle_<date>.ini.
  3. Open Slic3r Prusa Edition and select File->Load Config Bundle.
  4. Select the extracted .ini file and select OK.

Slic3r will display an indicator that the custom profiles have been successfully imported:
