Slic3r is free software 3D slicing engine for 3D printers.It generates G-code from 3D CAD files (STL or OBJ). Once finished, an appropriate G-code file for the production of the 3D modeled part or object is sent to the 3D printer for the manufacturing of a physical object. As of 2013, about half of the 3D printers tested by Make Magazine supported Slic3r.

What is Slic3r?
Compatible with your printer too. RepRap (Prusa Mendel, MendelMax, Huxley, Tantillus...), Ultimaker, Makerbot, Lulzbot AO-100, TAZ, MakerGear M2, Rostock, Mach3, Bukobot and lots more. And even DLP printers.

Fast G-code generation is fast. Don't wait hours for slicing that detailed model. Slic3r is about 100x faster than Skeinforge. It also uses multithreading for parallel computation.
Lots of input/output formats. Slic3r reads STL, AMF and OBJ files while it can output G-code and SVG files.
Do you like the graphical interface or command line? All the features of the user-friendly interface are also available from command line. This allows to integrate Slic3r in your custom toolchain and batch operations as you like.
Open source, open development. Slic3r is open source software, licenced under the AGPLv3 license. The development is centered on GitHub and the #slic3r IRC channel on FreeNode, where the community is highly involved in testing and providing ideas and feedback.
Dependencies? Nah. Slic3r is super-easy to run: download, double click and enjoy. No dependencies needed. Hassle-free. For MacOS X, Windows, Linux.
Print with dual multiple extruders. Print beautiful colored objects, or use your secondary extruder to build support material. Or put a larger nozzle on it and print a faster infill.
Use brim for the best adhesion. This unique feature improves built plate adhesion by generating a base flange around your objects that you can easily remove after printing.
Microlayering: save time, increase accuracy. You can choose to print a thicker infill to benefit from low layer heights on perimeters and still keep your print time within a reasonable amount.

Compose a plate but print one object at time. Use the built-in plating interface that allows to place objects with drag-and-drop, rotate and scale them, arrange everything as you like. The sequential printing feature allows to print one complete object at time in a single print job.
Cool cooling strategies. A very smart cooling logic will regulate your fan speed and print speed to ensure each layer has enough time to cool down before next one is laid on it.
Manage multiple printers, filaments and build styles. The configuration handling system was designed for people working with multiple machines and filaments: you can save configurations as presets for each category avoiding to multiply your saved configurations.
Enjoy support material. Automatic generation of support material for overhangs.

I just stumbled over this announcement: http://www.prusaprinters.org/introducing-slic3r-prusa-edition/ (Download: http://www.prusa3d.com/drivers/, one needs to install the 'Driver' (don't ask why, untick all samples they are just .stl and .gcode-files and generate some bloat, ditto the Windows-Driver) and I'm quite interested in the new features Mr. Prusa added to this fork (kudos!), to mention 'Cubic infill' and 'Ensure wall thickness', especially the latter one.
Embedding this Slicer into RepetierHost worked after some faffin' around (the .ini-Files are in C:UsersPublicDocumentsPrusa3DSlic3r settings MK2 ...) but I'm missing the new Infill-options if I tick 'Override Slic3r settings', e.g. RH only shows 8 options for infill while Slic3rPE has 12).
Did I miss something or does RH show a static list here?
all the best

- The list comes from host and it does not know the new options. Next host release will have prusa slic3r as well and will show the options for it.
- FYI if you want only the Slic3r Prusa Edition then download it from here: https://github.com/prusa3d/Slic3r/releasesQuestion: do you plan to integrate it with more features e.g. variable layer height; individual infill ....
- @Repetier:
Do you guys _ever_ sleep (or just call it a day)?
*kudos*
@Rossini:
I must have missed this one somehow (JP's site ain't that intuitive IMO), please do tell how you found this link ;-) - @xBot150:the link is in the article you posted
- oops.. call me blind or 'reading too fast for his own good' (= adjust XY-Jerk maybe? ;-D)
but let's not derail this thread (... says the one responsible for ...)
*ahem* - It will work like other slic3r just supportingt the new options. Will come in april i guess.
