Stable processes despite abrasive filaments<\/span><\/h1>\n

\u00a0Abrasive materials quickly push conventional printer nozzles to their limits. With DIANOZ, Mach-3D is opting for a wear-resistant solution for reproducible printing processes \u2013 and will in future integrate the diamond nozzle as standard into its systems.<\/p>\n

Mach-3D<\/a> brings together several additive production technologies under one roof: since 2024, the company has been operating FDM, SLA and SLS systems for prototype manufacturing and series production just outside Kiel. In addition, Mach-3D develops and manufactures its own industrial 3D printing systems, which are used to print functional components, fixtures, housings, machine components and large-format technical components. The materials used are primarily engineering plastics and glass fibre-reinforced materials.<\/p>\n

Abrasive materials as a challenge<\/h2>\n

The demands are high \u2013 particularly on a small but central part of the 3D printer: the printer nozzle. \u201cFor us, process reliability, wear resistance and consistently high print quality are the top priorities,\u201d explains Erik Dieckmann, director of Mach-3D. \u201cThe nozzle must ensure consistent extrusion behaviour over a long period, even when using abrasive materials. Furthermore, we expect high dimensional accuracy of the components, clean surfaces and the ability to reliably achieve higher material throughput rates for industrial applications.\u201d And that is often where the real challenge lies of the matter lies, as Dieckmann knows from experience: \u201cThe biggest challenge lies in the high abrasiveness of glass fibre-reinforced materials. Conventional nozzles wear out relatively quickly in this context.\u201d<\/p>\n

In practice, this frequently led to unstable processes at Mach-3D. The nozzle diameter changed over time, and with it the extrusion behaviour of the nozzle. The result: fluctuations in quality, additional testing effort and unplanned downtime. The limitations of conventional nozzles became particularly apparent with large-format components requiring long runtimes of hours or even days, as well as in projects involving high proportions of glass fibre-reinforced materials.<\/p>\n

Traditional solutions reach their limits<\/h2>\n

Mach-3D attempted to tackle the wear problem when printing abrasive materials using steel nozzles and ruby nozzles. However, neither approach provided a stable solution for continuous industrial use. With the steel nozzles, wear occurred during prolonged use, which affected print quality. Although ruby nozzles offered high wear resistance, they were more sensitive to mechanical stress. \u201cFor day-to-day operations, this meant additional maintenance work and, in some cases, unplanned downtime,\u201d said Deickmann. It was therefore crucial to find a nozzle that not only lasts longer but also delivers consistent results.<\/p>\n

DIANOZ restores process stability<\/h2>\n

The switch to a stable solution was achieved with G\u00fchring\u2019s DIANOZ diamond nozzle. What makes this nozzle so special is that the DIANOZ features a polycrystalline diamond (PCD) tip with a significantly higher hardness than brass or hardened steel, ensuring that the geometry and exit diameter remain stable even with abrasive filaments. The filament channel is friction-optimised and diamond-reinforced in the tapered section, to minimise wear and flow disturbances. Due to diamond\u2019s high thermal conductivity, the actual nozzle temperature largely corresponds to the setpoint temperature, resulting in reproducible thermal conditions in the melt zone.<\/p>\n

For Mach-3D, the benefits are evident in operation: \u201cFor us, the greatest advantage lies in the combination of high wear resistance, process reliability and consistent print quality,\u201d says Erik Dieckmann. DIANOZ finally provides him with the reliability he had been seeking. \u201cIt was clear even after the first print tests that the nozzle had been developed for industrial use,\u201d reports Dieckmann. He was particularly impressed by the combination of high-quality workmanship, technical design for abrasive materials and G\u00fchring\u2019s experience as a machining specialist.<\/p>\n

Consistent quality over long runtime<\/h2>\n

The benefits are particularly evident during long-term use. Whilst the print pattern changes with conventional nozzles, DIANOZ remains stable. \u201cEven after processing abrasive materials, we could not detect any significant changes in terms of print pattern, material flow or component quality,\u201d confirms Dieckmann.\u00a0This stability improves reproducibility. Dimensional accuracy and surface quality remain constant, regardless of runtime. At the same time, maintenance requirements are reduced. \u201cWe have been able to significantly reduce the effort involved in inspection, maintenance and nozzle replacement,\u201d explains Dieckmann.\u00a0 The machines can run for longer periods without intervention, making production planning easier.<\/p>\n

Partnership rather than a supplier relationship<\/h2>\n

Mach-3D now uses the diamond nozzle as standard in its own production. \u201cA close technological partnership has developed from what was once a traditional supplier relationship,\u201d says Dieckmann. The director particularly values the fact that G\u00fchring combines two crucial factors: outstanding product quality and decades of experience in the field of high-wear-resistant precision tools. \u201cWhilst many suppliers come exclusively from the 3D printing sector, G\u00fchring brings extensive expertise from the fields of machining and materials technology,\u201d notes Dieckmann. \u201cThis expertise is directly reflected in the level of performance of the DIANOZ nozzles.\u201d<\/p>\n

The collaboration is now leading to a OEM partnership. Mach-3D will use DIANOZ as standard in its new large-format printers. \u201cFor our new machine, it was clear that we wanted to offer our customers a tried-and-tested solution right from the start, including for the printer nozzle,\u201d says Dieckmann, explaining the decision. DIANOZ meets the industry\u2019s high requirements, and in combination with Mach-3D\u2019s large-format printers, this creates a seamlessly integrated system for users.<\/p>\n

\u201cOur customers benefit from greater process reliability and improved predictability,\u201d explains Dieckmann. The partnership between G\u00fchring and Mach-3D thus demonstrates how additive manufacturing can be industrialised \u2013 through components that deliver in operation and through collaboration that extends beyond the products themselves.<\/p>\n
