## Is it usable already? Any known limitation?
|

|

Sure, it's very usable. Remember that:

* it only works well with manifold and clean models (check them with Meshlab or Netfabb or http://cloud.netfabb.com/).
|

* more fill patterns;

## How to install?

It's very easy. See the [project homepage](http://slic3r.org/)
