This is a 3D printing 3D Model GCode/SVG slicer, written in Python, based on the Clipper geometry library. It will let you take 3D model files like STL, 3MF, OBJ, AMF, OFF, 3MJ and generate a GCode path file that you can send to your RepRap 3D printer to print the object.
Install using PyPi (NOT IMPLEMENTED YET):
unzip mandoline-py.zip cd mandoline-py pip3 install .
Installing from sources:
python3 setup.py build install
To just validate a model, checking it for manifold errors, just run
mandoline with the name of the file:
mandoline cube.stl
Any error messages will be printed to STDERR, and the return code
will be non-zero if errors were found.
To slice a file into GCode, you need to specify the file to write to with the -o OUTFILE arguments:
mandoline -o cube.gcode cube.stl
If you want to force it to skip validation, then add the -n argument:
mandoline -o cube.gcode -n cube.stl
To display all slicing config options, use the --show-configs argument:
mandoline --show-configs
To get descriptions about all slicing config options, use the --help-configs argument:
mandoline --help-configs
You can set slicing options on the command-line with -S NAME=VALUE args:
mandoline -S layer_height=0.3 -S skirt_lines=3
You can write changed options to the persistent slicing configs file using the -w argument:
mandoline -S layer_height=0.3 -S brim_width=3 -w
You can query the value of a slicing config option with the -q OPTNAME argument:
mandoline -Q layer_height -Q brim_width
You can view the sliced output in a GUI window if you add the -g argument. In this window, up and down arrow keys will move through the slice layers, and the 'q' key will quit and close the window. The keys 1 - 4 or - and = will zoom the image.
- Fixing non-manifold or general get more linient on models
- 3DBenchy fails to slice without -n
- Voron_Design_Cube_v7 slices wrong as seen with -g
- Allow case-insensitive settings (infill_type, support_type, adhesion_type, bed_geometry)
- Resolve "shell" vs "wall" vs "perimeter" in source variables, source comments and config
- ~~Support more import formats, e.g. 3MF~~ done 0.8.6: 3MF, OBJ, OFF, AMF and 3MJ formats added
- Enable multi-model loading/placement/rotation
- 0.8.4: -M scale=s or -M scale=x,y,z for single model
- Verify models fit inside build volume
- Interior solid infill perimeter paths
- Pathing type prioritization
- Optimize route paths
- Skip retraction for short motions
- Smooth top surfacing for non-flat surfaces
- G-Code custom startup/shutdown/toolchange scripts
- 0.8.3: start_gcode and end_gcode added
- G-Code flavors
- G-Code volumetric extrusion
- Relative E motions
- Better Bridging
