DESCRIPTION
Slic3r is a STL-to-GCODE translator for RepRap 3D printers written by Alessandro Ranellucci

OPTIONS
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
--split
Split the shells contained in given STL file into several STL files
--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)
--autosave <file>
Automatically export current configuration to the specified file
Output options:
--output-filename-format

values, as well as [input_filename_base] and [input_filename] (default:

--post-process
Generated G-code will be processed with the supplied script; call this more than once to
process through multiple scripts.
