Slicer builds

Custom SimplyPrint slicer builds and generated slicer configuration artifacts.

Repository layout

• tools/ contains shared helper tools, including apply_versioned_patches.sh and generate_defs_visibility.
• slicers/<Slicer>/steps/ contains build, run, dependency, and packaging scripts for each slicer.
• slicers/<Slicer>/patches/ contains dump patches plus optional versioned patches. Binary-only patches live under patches/binary/.
• slicers/<Slicer>/out/ contains generated artifacts:
  • .cache/ for workflow cache placeholders.
  • nightly/ for nightly dumped configs.
  • <version>/ for release dumped configs.
  • _index.json as the single version/build/config index for that slicer.

PrusaSlicer 3.0 config builds additionally publish config-model.json, the native configuration schema, and profile-bundle.json, an evaluated profile bundle. The latter keeps native preset IDs and machine/process/tool compatibility contexts that cannot be represented safely by the legacy INI profile shape. The four legacy configuration artifacts remain available for existing consumers. Building the 3.0 dependency stack requires CMake 3.26 or newer.

All slicer step scripts are run from the repository root with slicer-src and slicer-out available.

Licensing

This repository — the build scripts, CI workflows, shared tools, and patches — is licensed under the GNU Affero General Public License v3.0 (AGPL-3.0), with no additional terms.

The patches under slicers/<Slicer>/patches/ modify upstream slicer source code and are therefore also governed by the corresponding upstream license. A copy of each upstream project's license is kept at slicers/<Slicer>/LICENSE:

Binaries built from the patched sources are covered works of the corresponding upstream slicer and remain AGPL-3.0. Generated configuration artifacts under slicers/<Slicer>/out/ inherit the status of the slicer data they are derived from.
