INDX Passive Tool (Steel CHT) for Induction Toolchanging

Performance Redefined: INDX Thin Passive Tools

The INDX Passive Tool is the breakthrough component that makes the entire ecosystem possible. By stripping away the heater cartridges, thermistor wires, and heavy heat blocks of traditional hotends, we have created a nozzle assembly that is thinner, lighter, and vastly more reliable, without compromising on performance.

CHT Power

Every INDX Passive Tool is built from steel, with a brass insert, for dependable, long-service performance, purpose-made to work with the INDX induction heating system. Inside, each tool uses our patented Bondtech CHT (Core Heating Technology). By splitting the filament into three thinner strands, the nozzle melts material from within, significantly boosting flow rates and ensuring strong layer adhesion even at high print speeds.

Pure Performance, Zero Electronics

This is a "passive" device in the truest sense. It contains no electronics, no connectors, and no moving parts. Instead, it relies on the induction coil inside the INDX toolhead to generate heat contactlessly. This means the tool itself is incredibly robust, there are no crimps to fail, no wires to fatigue from constant motion, and no delicate sensors to break.

Featherweight Agility

Weighing a fraction of a standard print head, the Passive Tool minimizes the moving mass on your gantry. This reduction allows for higher acceleration and reduced ringing (ghosting). Combined with the high-flow capabilities of CHT, you can push your print speeds to the limit.

Seamless Integration

Designed to mate perfectly with the INDX openable extruder, the Passive Tool features a streamlined filament path that allows the extruder gears to engage directly. Held in place by high-precision kinematic coupling, every tool ensures micron-perfect repeatability, layer after layer.
