Bondtech INDX is a novel solution for tool changer systems composed of a single smart tool head and multiple thin passive tools.

On the multi-material-color-nozzle printing space, the INDX is solving the required high marginal investment for each additional tool; hardware, material and energy waste; and high printing times.

The INDX is for all people to make 3D prints with several materials, colors and/or nozzle diameters on the same print or print job. People can also prepare and park tools to quickly pick and use on later prints.

• It’s self-adjusting. The extruder on the smart tool head self-adjusts without user action to:
  • different filaments;
  • required volumetric flow;
  • other printing conditions.
• It’s hotendless. The INDX uses thin passive tools with no hotend and requires one single smart tool head for multi-material application.
• It’s contactless and wireless. The INDX heats up the nozzles and reads their temperature without contact to, or wires on, the tools.
• It’s near massless. The INDX nozzles broke tradition and are so low thermal mass that all heating power is mostly used to directly melt plastic.
• It’s super-fast. The INDX currently takes just up to 12 seconds to complete each tool change. It cools down very fast and minimizes oozing. It heats up even faster to quickly resume printing. Currently it may take as little as 4 seconds to reach printing temperature.

We will continue to develop INDX with our community in the following months and plan to launch it during FormNext late November 2025.

We aim for the INDX to be a cost-efficient tool changer. Targeting for each thin passive tool to cost around 35 EUR/USD and for the smart tool head to cost around 250 EUR/USD.

Yes, both INDX Thin Passive Tools and INDX Smart Tool Head will be available to purchase separately.

Yes, we always do. Bondtech INDX will be tested by a limited group of highly skilled and motivated people we trust to give us useful and relevant feedback to improve our systems.

This feedback will include testing data gained by following protocols as well as stress testing the system.

Yes, INDX is protected by patents. We’ve secured IP for specific, novel technologies at its core, without targeting existing tool-changing features or limiting others from creating tool changers. Our focus is on protecting what makes INDX unique, while encouraging innovation, open-source collaboration, and non-commercial projects. Commercial use of INDX’s IP protected aspects requires proper licensing to ensure fair and sustainable growth.

Our submitted patents, trademarks, and industrial design protections serve several important purposes: they give us the freedom to operate without interference, help generate the revenue that fuels continued innovation, and safeguard our Partners and their INDX-embedded creations. These passionate creators build the remarkable machines that bring real value to all of us.

DX is short for Dynamic eXtruder. INDX uses a new and clever dynamic dual driving technology that self-adjusts, to the optimal pre-tension required to print any material, at any requested volumetric flow, and under any 3D printing conditions. Click here to know more
