Prusa CORE One+ INDX: Bondtech Admits Quality Issues with Steel Nozzles

As Tom’s Hardware reports (https://www.tomshardware.com/3d-printing/nozzlegate-erupts-as-prusa-core-one-3d-ptinter-kits-arrive-with-soft-steel-nozzles-bondtech-admits-machining-flaws-with-no-quick-fix), Bondtech, the manufacturer of the INDX Toolchanger system used in the Prusa CORE One+ INDX 3D printer kit, has admitted to a serious labeling error regarding the supplied nozzles. The nozzles do not meet the advertised "hardened steel" standard but are made from softer steel, which can affect durability and performance.

Background and Technical Details

Bondtech is known for its high-quality extruder and nozzle components used in many 3D printers. The INDX Toolchanger system, which enables modular tool-changing functionality, was highly anticipated as it promises flexibility and precision. According to the manufacturer, the supplied nozzles were supposed to be made of hardened steel to reliably process particularly abrasive materials such as carbon fiber or metal filaments.

The now identified deviation means that the nozzles may wear out faster, leading to print errors, uneven material feed, and ultimately a shorter lifespan of the components. Bondtech has acknowledged that this is a manufacturing defect related to the hardness of the steel and that there is currently no quick fix to retrofit the affected kits with correct nozzles.

Impact on Users and Market

For users of the Prusa CORE One+ INDX kit, this means they must expect potentially limited performance, especially when using abrasive filaments. The community is already actively discussing possible workarounds, such as replacing the nozzles with third-party products or using less abrasive materials.

Prusa Research itself has so far remained cautious but points to close cooperation with Bondtech to find a satisfactory solution. For Bondtech, the situation is a severe setback, as the brand stands for precision and quality and customer expectations are high.

Why It Matters

The quality of nozzles is a crucial factor for reliability and precision in 3D printing. Especially for professional or semi-professional users who rely on durable components, such an error can lead to significant costs and time losses. Furthermore, the incident raises questions about quality control at suppliers and manufacturers, who must meet increasing demands in a growing market.

For the 3D printing industry, this again highlights the importance of transparent communication and rapid problem-solving to maintain user trust. The debate around "Nozzlegate" could also encourage other manufacturers to critically review their own quality standards.

Outlook

Bondtech has announced plans to revise nozzle production and implement stricter controls in the future. Customers affected by the issue are asked to contact support to discuss possible replacement solutions. Whether and when an official exchange program will start remains to be seen.

Overall, this case underscores how sensitive hardware components in 3D printing are and how important reliable material and manufacturing quality are for the success of new products.
