_Q: Oh cool, a new RepRap slicer?_

# Slic3r
|
|
|
|
## What's it?
|
|
|
|
Slic3r is an STL-to-GCODE translator for RepRap 3D printers,
|
|
like Enrique's Skeinforge or RevK's E3D.
|
|
|
|
## Why a new one? Why Perl?
|
|
|
|
The purpose is to build something more maintainable and flexible than both
|
|
Skeinforge and E3D. The code makes extensive use of object-oriented
|
|
programming to achieve some level of abstraction instead of working with
|
|
raw geometry and low-level data structures.
|
|
This should help to maintain code, fix bugs and implement new and better
|
|
algorithms in the future.
|
|
I also aim at implementing better support for hollow objects, as Skeinforge
|
|
isn't smart enough to generate internal support structures for horizontal
|
|
facets.
|
|
|
|

|
|
|
|
## What's its current status?
|
|
|
|
Slic3r current features are:
|
|
|
|
* read binary and ASCII STL files;
|
|
* generate multiple perimeters (skins);
|
|
* generate rectilinear fill;
|
|
* set 0% - 100% infill density;
|
|
* set infill angle;
|
|
* retraction;
|
|
* skirt (with rounded corners);
|
|
* use relative or absolute extrusion commands;
|
|
* center print around bed center point;
|
|
* multiple solid layers near horizontal external surfaces;
|
|
* ability to scale, rotate and multiply input object;
|
|
* use different speed for bottom layer.
|
|
|
|
Roadmap includes the following goals:
|
|
|
|
* output some statistics;
|
|
* allow the user to customize initial and final GCODE commands;
|
|
* support material for internal perimeters;
|
|
* ability to infill in the direction of bridges;
|
|
* cool;
|
|
* other fill patterns;
|
|
* nice packaging for cross-platform deployment.
|
|
|
|
## Is it usable already?
|
|
|
|
Yes, although its extrusion math needs to be tested.
|
|
I need to write a script to install dependencies and to package
|
|
dependency-free executables for main platforms.
|
|
|
|
## Can I help?
|
|
|
|
Sure! Send patches and/or drop me a line at aar@cpan.org. You can also
|
|
find me in #reprap on FreeNode with the nickname _Sound_.
|
|
|
|
## What's Slic3r license?
|
|
|
|
Slic3r is dual-licensed under the _Perl Artistic License_ and the _AGPLv3_.
|
|
The author is Alessandro Ranellucci (me).
