Modeling software only records the coordinates of objects, it doesn't describe the internal structure of the object or how to print the object. To do this, we use a program called a slicer.
The slicer program converts the OBJ or STL file into G-Code, a machine readable file that instructs the 3D Printer on how to construct the object. It also creates the internal structure of the object - called the infill.
Here is some of the slicing programs that we use in the Makerspace. Most of these are open-source and free to download and use on your home computer.
