If you want to make your multi-material printing less wasteful and more speedy get the Multi-Mix Plan.
It includes the tool clustering feature saving around 50% in filament and 40% in printing time (or even more when using an 'airbrush nozzle' and settings on high).
And it includes the color creation tool, giving you all the options to get great colors using 'image search', palette generation tool and color picker.
(You can match all colors to your colors in your printer profile and later also to the filament database of the Fila-Track Plan when that becomes available)
