We don't have this machine, so there's no photo. We don't use manufacturer renders.
Overview
We don't have this printer. Everything on this page comes from the manufacturer, with a source for each fact. See the machines we're testing.
The enclosed Prusa CORE One+ fitted with Bondtech's INDX passive-tool changer, sold as a factory-built printer or as a 4- or 8-tool conversion kit.
INDX uses one Smart Head with an induction coil and up to eight passive tools. Each tool is a nozzle with its own filament path and no electronics, parked in a dock. When the head picks up a tool, it heats the nozzle by induction and senses temperature contactlessly. Parked tools cool down, which Prusa says prevents oozing. Prusa claims about 12 s per change, measured from the last extrusion of one material to the first extrusion of the next, and about 0.013 g purged per swap.
The included nozzles are surface-hardened nitrocarburized steel, which Prusa says is not intended for long-term abrasive printing (rated for example to 10 kg of PETG-CF). INDX reduces build volume to 248×205×270 mm: 2 mm less in X and 15 mm less in Y. Speed and acceleration figures are not published for the INDX configuration.

Our measurements
Results from our own runs, tied to the exact configuration, firmware, and benchmark version.
Not tested. This printer isn't in our lab, so we have nothing of our own to report.
Benchmarks are drafts until we've piloted them on all three machines. How we test
