Slic3r 1.1.4 is a STL-to-GCODE translator for RepRap 3D printers written by Alessandro Ranellucci <[email protected]> - http://slic3r.org/

Common options:

--help

Output usage screen and exit

--version

Output the version of Slic3r and exit

--save <file>

Save configuration to the specified file

--load <file>

Load configuration from the specified file. It can be used more than once to load options from multiple files.

-o, --output <file>

File to output gcode to (by default, the file will be saved into the same directory as the input file using the --output-filename-format to generate the filename.) If a directory is specified for this option, the output will be saved under that directory, and the filename will be generated by --output-filename-format.

Non-slicing actions (no G-code will be generated):

--repair

Repair given STL files and save them as <name>_fixed.obj

--cut <z>

Cut given input files at given Z (relative) and export them as <name>_upper.stl and <name>_lower.stl

--info

Output information about the supplied file(s) and exit

-j, --threads <num> Number of threads to use (1+, default: 2)

GUI options:

--no-plater

Disable the plater tab

--gui-mode

Overrides the configured mode (simple/expert)
