Gauss MT90 brings paste-based metal extrusion to office and laboratory environments

With the growing adoption of additive manufacturing, the question of safe and energy-efficient metal 3D printing processes is increasingly coming into focus. The new Gauss MT90 metal 3D printer addresses this environment with an approach that differs significantly from conventional laser- or welding-based systems. Developed by Gauss, the system is based on paste-based metal extrusion (PME) and completely dispenses with metal powders and high-temperature processes.

Moving away from powders not only reduces explosion and dust risks, but also enables use outside traditional industrial halls. According to the manufacturer, the MT90 is designed for offices and laboratories. An integrated HEPA filter prevents the escape of emissions, while an LED status system clearly visualizes the operating state. This positions the system for development environments in which additive manufacturing has so far only been possible to a limited extent for safety reasons.

Operation is designed for a low barrier to entry. A quick-start mode handles the basic configuration, and an automatic print-bed exchange system enables continuous operation. According to the manufacturer, the system can also be integrated into automated production workflows.

From a technical perspective, the MT90 relies on a combination of camera-based viscosity monitoring, precise dosing logic, and controlled extrusion. These control loops are intended to ensure uniform material deposition, which is particularly relevant for components with fine structures. Typical applications cited by Gauss include heat sinks and electronic components, where dimensional accuracy and surface quality are critical. The quick-start mode automates parameter setup, allowing even inexperienced users to produce their first parts within a short time.

Another focus is on integration into automated environments. The system features an automatic build-plate change that can be integrated into existing production lines. Supported materials include stainless steel 316L, copper, titanium, and aluminum, covering both prototyping and near-series applications. By dispensing with high-power lasers, energy consumption and noise emissions are significantly reduced, positioning the MT90 as an option for sustainable and continuous metal manufacturing.
