_Q: Oh cool, a new RepRap slicer?_
2011-09-01 19:06:28 +00:00
A: Yes.
# Slic3r
## What's it?
2011-09-27 07:49:43 +00:00
Slic3r is an STL-to-GCODE translator for RepRap 3D printers,
2011-09-01 19:06:28 +00:00
like Enrique's Skeinforge or RevK's E3D.

See the [project homepage](http://slic3r.org/) at slic3r.org
for more information.

## Why a new one? Why Perl?
2011-09-01 19:06:28 +00:00
The purpose is to build something more maintainable and flexible than both
2011-09-01 19:06:28 +00:00
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?
2011-09-05 18:00:59 +00:00
Slic3r current features are:
2011-09-05 10:21:27 +00:00
* multi-platform (Linux/Mac/Win);
* easy configuration/calibration;
2011-09-05 10:21:27 +00:00
* read binary and ASCII STL files;
* generate multiple perimeters (skins);
2011-09-26 13:51:22 +00:00
* generate rectilinear fill;
* set 0% - 100% infill density;
* set infill angle;
* retraction;
* skirt (with rounded corners);
2011-09-05 10:21:27 +00:00
* use relative or absolute extrusion commands;
* infill every N layers (like the "Skin" plugin for Skeinforge);
* detect optimal infill direction for bridges;
* save configuration profiles;
2011-09-05 10:21:27 +00:00
* center print around bed center point;
* multiple solid layers near horizontal external surfaces;
2011-11-07 14:49:07 +00:00
* ability to scale, rotate and duplicate input object;
* customizable initial and final GCODE (using command line only);
* use different speed for bottom layer and perimeters;
* experimental support for G2/G3 native arcs.

2011-09-05 11:33:09 +00:00
Roadmap includes the following goals:
2011-09-05 10:21:27 +00:00
* output some statistics;
* support material for internal perimeters;
* new and better GUI;
2011-09-05 10:21:27 +00:00
* cool;
* other fill patterns.

## Is it usable already?
2011-10-03 14:45:34 +00:00
Yes!
## How to install?
2011-10-03 14:45:34 +00:00
It's very easy. See the [project homepage](http://slic3r.org/)
for instructions and links to the precompiled packages.
