for offset2() with clear meaning. New ClipperUtils functions: expand(), shrink() as an alternative for offset() with clear meaning. All offset values for the new functions are positive. Various offsetting ClipperUtils (offset, offset2, offset2_ex) working over Polygons were marked as unsafe, sometimes producing invalid output if called for more than one polygon. These functions were reworked to offset polygons one by one. The new functions working over Polygons shall work the same way as the old safe ones working over ExPolygons, but working with Polygons shall be computationally more efficient. Improvements in FDM support generator: 1) For both grid and snug supports: Don't filter out supports for which the contacts are completely reduced by support / object XY separation. 2) Rounding / merging of supports using the closing radius parameter is now smoother, it does not produce sharp corners. 3) Snug supports: When calculating support interfaces, expand the projected support contact areas to produce wider, printable and more stable interfaces. 4) Don't reduce support interfaces for snug supports for steep overhangs, that would normally not need them. Snug supports often produce very narrow support interface regions and turning them off makes the support interfaces disappear. |

PrusaSlicer
You may want to check the PrusaSlicer project page. Prebuilt Windows, OSX and Linux binaries are available through the git releases page or from the Prusa3D downloads page. There are also 3rd party Linux builds available.
PrusaSlicer takes 3D models (STL, OBJ, AMF) and converts them into G-code instructions for FFF printers or PNG layers for mSLA 3D printers. It's compatible with any modern printer based on the RepRap toolchain, including all those based on the Marlin, Prusa, Sprinter and Repetier firmware. It also works with Mach3, LinuxCNC and Machinekit controllers.
PrusaSlicer is based on Slic3r by Alessandro Ranellucci and the RepRap community.
See the project homepage and the documentation directory for more information.
What language is it written in?
All user facing code is written in C++, and some legacy code as well as unit tests are written in Perl. Perl is not required for either development or use of PrusaSlicer.
The slicing core is the libslic3r library, which can be built and used in a standalone way.
The command line interface is a thin wrapper over libslic3r.
What are PrusaSlicer's main features?
Key features are:
- multi-platform (Linux/Mac/Win) and packaged as standalone-app with no dependencies required
- complete command-line interface to use it with no GUI
- multi-material (multiple extruders) object printing
- multiple G-code flavors supported (RepRap, Makerbot, Mach3, Machinekit etc.)
- ability to plate multiple objects having distinct print settings
- multithread processing
- STL auto-repair (tolerance for broken models)
- wide automated unit testing
Other major features are:
- combine infill every 'n' perimeters layer to speed up printing
- 3D preview (including multi-material files)
- multiple layer heights in a single print
- spiral vase mode for bumpless vases
- fine-grained configuration of speed, acceleration, extrusion width
- several infill patterns including honeycomb, spirals, Hilbert curves
- support material, raft, brim, skirt
- standby temperature and automatic wiping for multi-extruder printing
- customizable G-code macros and output filename with variable placeholders
- support for post-processing scripts
- cooling logic controlling fan speed and dynamic print speed
Development
If you want to compile the source yourself, follow the instructions on one of these documentation pages:
Can I help?
Sure! You can do the following to find things that are available to help with:
- Add an issue to the github tracker if it isn't already present.
- Look at issues labeled "volunteer needed"
What's PrusaSlicer license?
PrusaSlicer is licensed under the GNU Affero General Public License, version 3. The PrusaSlicer is originally based on Slic3r by Alessandro Ranellucci.
How can I use PrusaSlicer from the command line?
Please refer to the Command Line Interface wiki page.
