NAME
slic3r - Slice 3D models into G-Code for 3D-printing
SYNOPSIS
slic3r [ OPTIONS ] [ file.stl ] [ file2.stl ] ...
DESCRIPTION
Slic3r is a STL-to-GCODE translator for RepRap 3D printers written by Alessandro
Ranellucci <aar@cpan.org> - http://slic3r.org/
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>

Output options:
--output-filename-format

replaced by their values, as well as [input_filename_base] and

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