Q: Oh cool, a new RepRap slicer?

A: Yes.

Slic3r

What's it?

Slic3r is an STL-to-GCODE translator for RepRap 3D printers, like Enrique's Skeinforge or RevK's E3D.

See the project homepage at slic3r.org for more information.

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:

  • multi-platform (Linux/Mac/Win);
  • easy configuration/calibration;
  • 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;
  • high-res perimeters (like the "Skin" plugin for Skeinforge);
  • detect optimal infill direction for bridges;
  • save configuration profiles;
  • 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 and perimeters.

Roadmap includes the following goals:

  • output some statistics;
  • allow the user to customize initial and final GCODE commands;
  • support material for internal perimeters;
  • cool;
  • other fill patterns.

Is it usable already?

Yes!

How to install?

It's very easy. See the project homepage for instructions and links to the precompiled packages.

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).
