Xometry Supports Qinu in Manufacturing High-Tech Cooling Systems for Industry and Research

Building a CNC machine from scratch is full of moments where you find out whether your design actually works, or whether it only worked inside CAD. In the world of custom machine building, the transition from a digital model to physical assembly is rarely seamless. This was one of those moments.

In the world of custom machine building, I’ve found there is a constant tug-of-war between theoretical performance and physical reality. As "The Practical Engineer," I dedicated this project to creating a 5-axis CNC machine that prioritizes rigidity over sheer speed.

The HTL team from Austria overcame mass distribution and precision challenges to successfully build Cubli, a self-balancing cube powered by reaction wheels and control algorithms.

Go behind the scenes for the development of Torx: the combat robot built by Accu for FightFest 2026, with CNC machining support from Xometry. Explore the journey from the drawing board to the arena, showing how a combat robotics project takes shape, and see how Torx went on to win the official FightFest Championship trophy.

By using agile testing and redesigning a double-sided support to resolve motor deformation and calibration challenges, the TGM student team successfully turned 3D printing waste into high-quality PLA filament.

With Xometry, we have found a manufacturing partner that supports our development philosophy. The ability to quickly and precisely order small batches of parts gives us the freedom to iteratively improve our robots. This flexibility is essential to our innovation process.

In the past, developing non-standard devices was always complicated by the issue of tolerance matching between externally purchased standard parts and custom-machined components. Xometry's one-stop solution perfectly solved this pain point: they not only handled the complex metal 3D printing and sourcing of components but also delivered a finished product that had undergone precision assembly and adjustment. What we received was a functionally ready component that met our precision requirements. This efficient and worry-free delivery experience is exactly what R&D personnel need.

“Xometry’s engineers took the initiative to help me solve technical problems and provided plenty of professional advice on optimizing the manufacturing details of the shell design. They responded to my feedback and solved issues in the first place, which is truly rare in this industry.”

Elettra Sincrotrone Trieste, an Italian research center operating since 1993, is upgrading to Elettra 2.0, a fourth-generation synchrotron facility. With Xometry's CNC machining, they produced a high-precision XYZ motion system for the Spectromicroscopy beamline, featuring ceramic and OFHC copper UHV-compatible components, vibration-isolated support feet, and nanometer-level positioning accuracy.

A student team from University of Maribor developed a stainless steel hose clip for the food and beverage industry, targeting wine and beer fermentation vessels. With Xometry's laser cutting service, they produced 1.5mm thick stainless steel sheet parts featuring elongated teardrop-shaped holes that pinch hoses at two points. The 80 × 45 × 170 mm design requires no lubrication, is food-safe, and grips vessel flanges securely without screws.

Emiel, an aerospace engineering graduate and creator of "The Practical Engineer" YouTube channel, built two magnetic coupling prototypes: magnet-to-magnet and magnet-to-copper using eddy currents. With Xometry's laser cutting service, he sourced copper plates of 3mm and 6mm thickness, discovering that the copper version enables smooth, self-regulating, non-contact torque transfer with 8mm gap capability.

The lessons we learned go far beyond mechanics. We reflect on three key takeaways: people are the ultimate success factor — both the team and its supporters; divide and conquer: breaking the project into subsystems prevents chaos and enables parallel innovation; and industry partners like Xometry are strategic enablers, not just suppliers.
