Importing multiple STL files as a single multi-material model

First of all, switch the printer preset to a multi-material printer (such as the MMU2S), otherwise, the following steps won't work.

Then you can either:

  1. Drag and drop all of the STL files at once into the 3D view
  2. Select File - Import - and select all STL files at once
  3. Select Add... Ctrl + I from the top toolbar and select all STL files at once

PrusaSlicer will ask you if it should represent the loaded models as one single object with multiple parts - confirm the prompt by selecting Yes

Importing single STL or OBJ file as a single multi-material model

The STL file format doesn't support multiple objects in a single file natively. However, it's not uncommon for multiple separate models/shell to be in a single STL anyway. PrusaSlicer will load such models as a single object. If you wish to split the objects into multiple parts, use the Split to parts function in the top toolbar.

Importing 3MF as multi-material model

3MF files natively support multiple objects in a single file, multi-material models should be automatically recognized and loaded correctly. Saving a project file (File-Save) is the ideal way of storing and sharing multi-material models for Prusa printers.
