Recall that the file format determines the information the file carries. The information contained in the CAD file is very important for successful printing. Some printers come with their own slicing software so you can send the model directly in the 3D printing file format. After this, the G-Code file is sent to the printer. The slicing software then scans the layers and uses the information to generate the G-Code – set of instructions on how the 3D printer should move to produce the required object. After a model has been created and saved in a 3D printing file format, the model has to be sent to a software to be sliced, a process in which a solid model is divided into numerous thin horizontal layers. File Formats and 3D PrintingģD printers build parts layer by layer. Depending on the file format of a CAD file, the file can contain geometry, material, texture, size, or colour data of a model. The data these bits carry, as well as the way they are encoded determine the nature and format of the file. All files, whether text, music, picture, or 3D models are made up of millions of bits.
