A popular and powerful slicing Free Software option

Slic3r converts your 3-Dimensional model (typically STL/OBJ) and determines the 3D printer tool path based on the options selected. This slicing software uses the nozzle diameter, printing/movement speeds, layer height, and other variables to determine the coordinates where it needs to move, and the rates at which it will do so. This information is exported out of the program as a GCODE file. The resulting GCODE file is a plain-text file with a series of text-based codes, and a list of the complete X,Y, and Z axis coordinates used for printing the 3D model.

In order to control your LulzBot 3D printer you'll need to use either the Graphical LCD controller or a separate printer host. Printer host software is available on our Download page. We recommend Cura as it contains the slicing software, printer host, and is easier for new users.
