What's Changed

It's no secret that OrcaSlicer, as well as other Slic3r forks, has struggled with spiral vase mode, especially with models featuring sloped surfaces and large line widths. This new PR, introduced by @andrewboktor, presents an improved smooth spiral vase mode inspired by Ultimaker Cura. It effectively eliminates visible seams in spiral vases. image image

Originally developed by the PrusaSlicer team and beloved by many users, the Measure & Cut gizmos have now been ported to OrcaSlicer, thanks to @Noisyfox. image

This "Reverse only internal perimeters" option is an extension to reverse on odd reversal is not executed on external perimeters. The primary use case for this PR is to greatly reduce part stresses as they are now distributed in alternating directions, which should reduce warping, while maintaining external wall quality. This can be very useful for warp prone material, like ABS/ASA and also for elastic filaments like TPU and Silk PLA. image image

This setting adds an extra wall every other layer. This way the infill gets caught between the walls, resulting in:

  • Theoretically, stronger prints due to better infill anchoring.
  • Allows for the infill/wall overlap to be set to low values without compromising object strength while maintaining external surface quality.
  • It may contribute to improving water tightness of models as the gaps between the top and bottom layers and the walls are overlapping.

  • Add ColPic encoding for thumbnails(;gimage/;simage) as metadata. This will enable showing preview images on QIDI/Elegoo/etc machines. QidiSlicer's implementation of this format is referenced. by @SoftFever

  • Added a new handy model: Stanford bunny

This model is remixed by myself to make it 3d printable. Original model can be found at: graphics.stanford.edu/data/3Dscanrep/ ↗ image
