Once a model is finished in 3D design software, it still needs to be prepared using a special kind of software that translates the model into the script of machine instructions we mentioned earlier. This is done using slicing software, also referred to as a slicer. After importing your 3D model to the slicer, you can adjust the settings to meet your requirements. You can use the slicer to set many important parameters, such as printing speed and temperature, wall thickness, infill percentage, layer height, and many others.
The resulting file consists of G-code, the “language” of 3D printers and CNC machines. G-code is essentially a long list of instructions that the 3D printer will follow to build your model. In other words, 3D printing is impossible without G-code files!
Supports
One of the main functions of a slicer is to analyze your model and determine whether or not to generate support material. Specifically, supports are needed for parts with severe overhangs. The slicer lets you choose where to put supports and how dense you want them to be. Some slicers even offer users the ability to choose different types of support structures, which might be easier to remove or more stable.
When it comes to slicing software, there are a variety of options to choose from. Check out our slicing software guide to help you choose!
