Gauss MT90 Mold makers can use MetalPrinting’s paste-based metal extrusion (PME) 3D printer to produce complex metal inserts, cores and specialized tooling components. The printer is optimized to handle a variety of materials, including copper, titanium and aluminum, along with 316L stainless steel, which is widely used to produce durable mold components. An entry-level printer, the Gauss MT90 is appropriate for small- to medium-sized mold shops. It has an artificial intelligence (AI) camera-based viscosity unit, precision dispensing algorithm, extrusion control system, a built-in HEPA filter that blocks emissions, and an LED signaling system that delivers status feedback. Its Quick Start mode automatically configures process parameters, enabling even first-time users to start printing within minutes. Its automatic bed replacement system simplifies workflows and integrates with automation.

What’s new? The printer, which MetalPrinting officially launched in the U.S. at the end of summer. 

Benefits Cost-effectiveness, efficiency and safety. The Gauss MT90 can make parts that are difficult or costly to manufacture using traditional CNC machining. It is capable of stable deposition for high-precision parts such as heat sinks and electronic components. Unlike powder- or welding-based systems, the Gauss MT90 removes dust and explosion risks from high-temperature processes, making it safe for offices and laboratories. Also, because its paste system doesn’t require high-powered lasers and heating, the MT90 lowers energy use and carbon emissions, supporting sustainable manufacturingIt has a low-noise design.
