With version 2.3.1, developer SoftFever has released the latest edition of the popular open-source slicer OrcaSlicer. The update focuses on bug fixes, optimized G-code processing, and numerous detail improvements in the profile and translation system. Users will benefit in particular from more stable handling of complex print files and new options for more targeted component reinforcement.
A key new feature concerns the control of infill behavior. Users can now insert additional solid infill layers at defined levels to specifically reinforce critical areas. This is particularly relevant for functional components, such as at attachment points or for tall, slender objects. The function supports both interval patterns (e.g., every five layers) and explicit layer lists. This allows the strength of a model to be increased without adjusting the overall fill density.
In addition, the logic of infill rotation has been revised. Conflicts between the settings for “Sparse infill direction” and “Sparse infill rotation template” are now automatically avoided. This makes the slicer behave more predictably and keeps the toolpaths consistent. Other technical improvements relate to the calculation of Z-axis movements and stability when importing 3MF files from older versions.
There have also been many changes in the area of printer profiles. In addition to new presets for models such as the Sovol SV08 MAX, Qidi Q2, and FlyingBear devices, numerous existing profiles have been adjusted. Errors in start and end G-code scripts have been fixed, as have problems with “bed_exclude_area” on Anycubic printers.
The development team has also eliminated over 1,000 compiler warnings and revised the update process. Further details are available directly from OrcaSlicer.
