While Prusa Research continues to work on the next major version of its PrusaSlicer software, a smaller update, PrusaSlicer 2.72, was released late last week. It predominantly improves multi-material printing, with improved multi-material painting headlining the release.
By resolving issues related to detecting non-valid Voronoi diagrams, PrusaSlicer can now avoid spilled layers or crashes while ensuring better printing results with multiple materials.
There’s also a new method of color changing that helps eliminate blobs of a secondary filament color in the wrong place based on a user-created solution. In previous versions, color changing occurred after the previous layer was finished. Now, it happens after the nozzle has moved to the next layer – preventing pesky blobs and improving print quality.
Moving along, helical layer changes introduced in the last update have been replaced with a smoother ramping profile, which aims to reduce color blobs and artifacts potentially caused by helical movements. The profile also adjusts Z-axis movements to prevent unnecessary slowdowns, prevent stringing, and potentially result in faster print times.
Rounding out the update are material overrides for SLA printing, which allows users to fine-tune configuration settings; a sardonic goodbye to the Perl scripting language, which has now been fully replaced with C++; and a few bug and glitch fixes.
Prusa gives no indication of when the next major release for PrusaSlicer may arrive, although it does hint that another minor update may come before that time. Until then, check out the details for PrusaSlicer 2.7.2 on Prusa’s blog.
