All you have to do is drag the file into Cura and it will do it for you. Yes, you can actually directly convert 2D images into Cura and process them into a 3D shape. Keep in mind, these files are there to be converted to STL files, which can then be processed in your slicer to create the G-Code file which is needed for 3D printing.įiles that are supported in Cura (popular slicer) are: This is known as tessellation and can be created by most CAD software out there.Īlthough STL files are the most popular, there are other files you can use in 3D printing depending on the machine and software you are using. STL files are the most popular file format you’ll hear with 3D printing and are needed to create the main G-Code file.įrom a technical point of view, an STL file is an approximation of a 3D model using several size triangles to build the object up. In order to get this G-Code file, we need to get a STL (Stereolithography) file processed within a slicer software like Cura. The G-Code file format is needed for 3D printing.
