docker-prusaslicer

This repository tracks and containerizes Prusa3D's PrusaSlicer. The files here contain the Dockerfile, supporting scripts and instructions for usage.

If you're looking for a regular build of PrusaSlicer, the latest builds are available on PrusaSlicer's releases page.

To grab and run PrusaSlicer as a container (in GUI mode)

docker run --net=host \
-v /tmp/.X11-unix:/tmp/.X11-unix \
-v $PWD:/Slic3r/3d:z \
-v slic3rSettings:/home/slic3r \
-e DISPLAY=$DISPLAY \
--rm keyglitch/docker-slic3r-prusa3d

PrusaSlicer can also be run without the GUI, for slicing via scripts, etc. The slic3r-action repository is an example of this usage.

Container notes

• Your current directory will be mounted into the container at /Slic3r/3d (change the :z option as appropriate to :rw/:ro).

• Settings are persisted into the slic3rSettings volume.

• Fedora users: SELinux might block access to X by slic3r inside the container. Look in /var/log/messages or /var/log/audit/audit.log to see if this is happening (and for the relevant commands to fix).

• Alternatively, there might be a permission error upon trying to access X. Try running xhost local:root to fix (this is a temporary fix and must be reapplied when restarting the host).

Building the latest release locally

If the hub version is ever out of date (or for any other reason), it is possible to build an image locally. getLatestPrusaSlicerRelease.sh will automatically try to get the latest non-AppImage version through the GitHub API during the build process.

Building:

$ docker build -t docker-slic3r-prusa3d .

Convenience Script

A small script wraps the docker run command above. It also contains a commented out snippet for poking around the persistent volume.

Example

$ echo $PATH
/usr/local/bin:/usr/bin:/bin:/usr/local/sbin:/usr/sbin:/home/davidk/.local/bin:/home/davidk/bin
$ cp slic3r.sh /home/davidk/.local/bin/slic3r
$ chmod +x /home/davidk/.local/bin/slic3r
$ slic3r
