Prusa CORE One INDX: 8-Material Printing With Near-Zero Waste Is Now on Sale

Prusa Research and Bondtech have opened orders for the INDX, a toolchanger upgrade that turns the CORE One into an 8-material printer — and its headline number is not the tool count. It is the waste figure: 0.013 grams per nozzle swap, according to Prusa’s announcement. For anyone used to watching an AMS purge tower eat 5–15% of a multicolor job’s filament, that is the pitch in a single stat.

How INDX works

Instead of one smart toolhead per material — the expensive route traditional toolchangers take — INDX uses one smart toolhead and up to eight lightweight passive tools. The passive tools carry no motors, heaters or wiring, and sit on 35 mm centers so all eight fit inside a CORE One. The smart toolhead does the clever work: an aluminum body with induction heating and contactless temperature sensing that takes a nozzle from room temperature to printing temperature in seconds, plus Bondtech’s self-adjusting Dynamic Dual Drive feeder that adapts its grip automatically from flexible TPU to rigid composites. Details are on Bondtech’s INDX page and in VoxelMatters’ coverage.

Pricing and availability

The conversion kit for the CORE One and CORE One+ comes in two tiers: a 4-tool kit at $749 / €669 and an 8-tool kit at $999 / €899. Prusa Edition upgrade kits began shipping in June, with kits for the larger CORE One L — and fully assembled printers with INDX pre-installed — planned for later this year.

Why this matters

Multi-material printing in 2026 is splitting into two philosophies. Filament-switching systems (Bambu’s AMS, Prusa’s own MMU) are cheap but wasteful — every color change purges material. True toolchangers waste almost nothing but historically cost thousands; Bambu’s six-hotend H2C Vortek starts around $2,399 as a complete machine. INDX plants itself between the two: toolchanger physics at filament-switcher money, assuming you already own a CORE One.

The catch is exactly that assumption — INDX is exclusive to the CORE One platform. It is less an accessory than an argument for buying into Prusa’s ecosystem, and it makes the next round of purge-tower comparisons genuinely interesting. We will be watching early owner reports closely; if the 0.013 g figure holds up in real prints, the purge tower’s days are numbered.
