Slic3r provides excellent configuration settings, such as profiles that you can use to manage your filament, printer, and print settings quickly. However, sometimes you need to access these files if something goes wrong or if you need to add an older configuration to your new computer’s version of Slic3r. 

Slic3r stores its settings in a system directory, and this location will differ depending on what operating system you use. In these settings files, you can find your profiles, the BIOS, and all of the .exe files for Slic3r.

This article will help you find your Slic3r files when you need them. I’ll walk you through the simplest ways to find Slic3r’s settings and help you import and export configuration files so that you can get the most out of this fantastic slicing program. 

Where Are Slic3r Settings Stored on a Computer?

If you’ve found yourself in a situation where you need to access your Slic3r settings but cannot find them, there’s a reason for that. You won’t often need to access these files, and Slic3r intentionally hides them for you. 

Slic3r settings are stored in the system directory on a computer. These files are hard to find because you rarely need to use them, and changing the files could alter the program and make it unusable. 

Although you can access these settings files and all of Slic3r’s software package contents, you’ll need to know precisely where to look. 

Finding these files allows you to change your settings and configuration files within the program. Once you find the settings, you can ensure that your config settings are in the correct location and add older files to your current version of Slic3r in case of an update or new computer.

If you are an advanced user, you can use these files to change how Slic3r looks and reacts to other files and programs. For example, you can customize the Slic3r color scheme and add custom parameters for your profiles. Therefore, it’s useful to know where to find them.

How To Open Slic3r Settings

Opening Slic3r settings isn’t complicated if you know where to look. Many people seem to use the most challenging methods (such as using command lines), but you can find the config files, BIOS, .exe’s, and so much more with just a quick search through your computer’s files. 

Let’s look at how you can find the Slic3r settings on the most common operating systems:

How To Open Slic3r Settings on Windows OS

Opening up the Slic3r configuration settings on Windows is challenging if you don’t know what you are looking for or where to find it. However, it’ll take less than a minute if you know where to go. 

Here’s how to find Slic3r settings on Windows: 

  1. Open Slic3r. 
  2. Open your Files window and search for “Slic3r.”
  3. Your Slic3r files and BIOS should appear in the location where you put them when you downloaded the program. 
  4. Select your user profile in the left-hand panel in your Files window. You can also search for “AppData” in your search bar.  
  5. Select “AppData” and open it to see the files inside. 
  6. Select “Roaming.”
  7. Now, look for the Slic3r file and open it. 
  8. Find a file named “slic3r.ini” (it may also be called “0.55×0.2.ini”).
  9. You should find all of your configuration settings and profiles in this file. 

How To Open Slic3r Settings on Mac OS

Finding the Slic3r application files on a Mac is very simple. 

There are two separate ways you can access these files. The first way is to open Finder, click on your Mac’s general tab in the side panel, which should say something like “My Mac”), and then use the search function to look up “Slic3r.” Your settings file for your filaments, prints, and printers should pop up.  

If you need to make changes to Slic3r itself, you can use the second method. To do so: 

  1. Open the Slic3r application. 
  2. Open Finder. 
  3. Find your “Locations” section in the side panel and find a drive called “Slic3r.”
  4. Click on the “Slic3r” drive and right-click on the yellowish Slic3r icon that pops up.
  5. Once you right-click on Slic3r, select “Show Package Contents.”

Once you open up the package contents, you can access the code that stores your Slic3r settings in your system directory in case you want to move it. Otherwise, you can access the “local-lib” file to see all your configuration files within your copy of Slic3r.  

How To Export and Import Your Slic3r Settings

If you want to move your custom Slic3r settings from one computer to another, doing so is simple. You won’t even need to access the settings files directly. 

To import and export config files:

  1. Open Slic3r. 
  2. Click on the “File” menu at the top of your screen.
  3. Choose the import or export selection that you need. You can import a Gcode file, older Slic3r config files, or a bundle of config files to add new profiles to Slic3r. Otherwise, you can export your settings to re-upload later. 
  4. Select the file(s) you wish to import if you are importing. If you are exporting, choose an easy-to-find location to put your file. 

Importing and exporting is as simple as that! After you export a file, you can transfer it to another computer or use it to backup your filament, printer, and print settings. 

These files are also shareable, so you may be able to find custom configuration settings available for download online. Using config files from other users is a simple way to get started with Slic3r since you can quickly upload a new configuration for every printer or filament you use.

Final Thoughts

Although Slic3r stores its settings deep in your system directory, all it takes is a quick search to find whatever you are looking for. You can use your system’s file browser to find your AppData or Local Library for Slic3r, which will get you to the configuration files and other files, such as the system drivers. 

Finding these files allows you to add custom profiles to Slic3r, making locating, replacing, and exporting your config files simple. Once you develop more skills, you can customize Slic3r‘s color scheme and available printing parameters using the system files.
