Slic3r 1.3

Slic3r is the tool you need to convert a 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. It is totally open source and it's independent from any commercial company or printer manufacturer. Supports all the known G-code dialects (Marlin, Repetier, Mach3, LinuxCNC, Machinekit, Smoothie, Makerware, Sailfish).
