From the developer:

Slic3r is the tool you need to convert a digital 3D model into printing instructions for your 3D printer. It cuts the model into horizontal slices (layers), generates toolpaths to fill them and calculates the amount of material to be extruded.
Slic3r is bundled with the most important host software packages: Pronterface, Repetier-Host, ReplicatorG and has been supported/funded by almost all the main 3D printing companies in the world.
