Multicolor printing on filament machines has always involved compromises: lots of purging, slow swaps, or duplicating hardware across several heads. The INDX toolchanging system, now shown mounted on a Voron printer, goes after that problem. The maker describes it as empowering filament 3D printers with fast procedures, using tools that work wirelessly and contactlessly with near zero waste, and claims cost-effectiveness on top.
The layout is a docking carriage riding on the gantry, with a row of tool heads parked at the rear of the frame. Every parked head gets its own filament feed tube plus flexible cable tracks. Close-ups reveal a motorized dual-drive gear mechanism feeding filament, status LEDs on each tool, and a rendered head showing sensor windows, LED indicators and front alignment pins. Linear guide rails and drive belts handle the motion side of the carriage.
What stands out to me is the docking face: it carries no physical electrical connectors at all. Swaps happen as the carriage engages each head, and the claimed self-adjusting dual drive technology is meant to handle different colors and materials. Styling-wise, the head is a rounded black enclosure with illuminated accents in red, white and green, and the logo reads INDX with the X striped in green, yellow and red. The demonstration ends with a multi-colored Benchy in white, reddish-pink and yellow sitting beside a small purge tower.
One thing is still open: the exact base printer model in the announcement was not identified, and no maker comments clarify the details of this Voron installation. I would really like a full parts breakdown and a closer look at the docking sequence!
