3D printing essentials
Slicer software turns a 3D model into instructions your printer can follow. It divides the model into layers and prepares the settings needed to print each one.
Models commonly arrive as STL, OBJ or 3MF files. For filament printers, the slicer generates toolpaths and printer instructions, usually exported as G-code. Resin printers use a printer-specific file containing layer images and exposure settings.
Your slicer controls layer height, supports and material settings. For filament printing, it also controls settings such as infill, temperature and print speed. Understanding these settings is just as valuable as keeping your printer in good working order.
Start with the software recommended for your exact printer. Download the latest stable release from the official website, select the correct printer and material profiles, and preview the sliced layers before printing. Software supplied on an older USB stick or memory card may be out of date.
