Tool Change Sequence Tool change sequence is the order and method by which a multi-extruder or multi-tool 3D printer switches between nozzles or tools during a print job. It ensures seamless transitions between different materials, colors, or functions without contamination or layer misalignment. Advanced printers use independent tool heads, nozzle parking, or purge blocks to optimize the sequence. Proper tool change configuration minimizes oozing, color bleeding, and mechanical interference. It enhances print quality, productivity, and multi-material versatility, supporting complex designs and functional assemblies. |
