In case structural rigidity is not needed, a lot of material and printing time is saved with the new Lightning infill, which is optimized to support the top surfaces only. Infill serves a dual purpose – to provide structural rigidity and to support top surfaces. The import implementation itself was ported from BambuStudio, thanks go to them as well. We use the Open CASCADE Technology (OCCT) development platform to read the STEP files, so big thanks go to them for keeping it open-source. The conversion is fully automatic (the level of detail is not customizable). Right now we are tessellating the model on import (converting it to a triangle mesh), so the model is then sliced just like any other mesh and not analytically. Businesses that do print on demand can skip converting STEP files from the customer to STLs, saving precious time. On the other hand, STEP files can be edited quite easily, allowing for quick customizations and remixing. By being able to import STEP files directly, we expect a growing number of people to use STEP when sharing the design online instead of an STL, which is notoriously difficult to edit. This seemingly small addition could have large consequences.

This CAD file format is interoperable among most CAD programs and it is an ISO standard supported by programs such as Fusion 360, FreeCAD, SolidWorks, Inventor, AutoCAD, CATIA, and many more. Starting with this release, PrusaSlicer is able to import STEP files.
#PRUSA SLICER LOGO GENERATOR#
The Detect Thin walls feature is disabled when the Arachne perimeter generator is selected as it’s not needed since Arachne always tries to adapt the extrusion width to thin lines. If you want to use the old perimeter generator, you can switch to it in the Print settings – Layers and perimeters – Perimeter generator settings.
We have decided to set the Arachne perimeter generator as the new default option. The new perimeter generator doesn’t have this limitation and produces much cleaner texts even at a smaller scale. Drawing fonts with constant line width is obviously quite difficult. One field where the Arachne perimeter generator really shows its power is when printing texts or small logos. There is a significant reduction in gap fill, small extrusions used to fill gaps between perimeters, which also results in a reduction of print time.Ĭlassic perimeter generator in PrusaSlicer 2.4.2 vs Arachne perimeter generator in PrusaSlicer 2.5 The new approach produces nicer-looking prints with fewer artifacts. And now? As long as the wall thickness is close enough to 2 perimeters, PrusaSlicer will take care of the rest. This is a major change! Before, it was nearly impossible to create a wall that would fit 2 perimeters exactly. Simply put, it automatically makes perimeters wider or thinner as needed. The Arachne generator produces perimeter loops and gap fills with varying extrusion width. The developers of Cura recently implemented a new strategy named Arachne based on the paper. This caused issues in various cases, especially when printing thin walls, text, or logos.
