MetalPrinting’s GAUSS MT90 Debuts at CES 2026, Redefining Accessible Metal 3D Printing

The CES Innovation Award–honored GAUSS MT90 uses paste-based extrusion to simplify and lower the cost of metal additive manufacturing.

South Korean additive manufacturing specialist MetalPrinting has officially introduced its GAUSS MT90 paste metal 3D printer at CES 2026 in Las Vegas, marking a major transition toward safer and more affordable metal additive manufacturing for desktop.

The GAUSS MT90 uses Paste-based Metal Extrusion (PME) technology, in contrast with traditional industrial metal 3D printers that depend on high-power lasers or loose metal powders. This technique greatly lowers the dust, fire and explosion dangers associated with traditional methods by combining metal powder with a binder to create a paste that is extruded layer by layer at room temperature. This makes the machine appropriate for usage in typical offices and research environments.

The tiny device, which was named a CES 2026 Innovation Awards Honoree, presented itself as a desktop-friendly option for the fabrication of small metal parts with a build volume of approximately 85 × 85 × 60 mm, a machine footprint of 420 × 420 × 500 mm and a weight of approximately 30 kg.

30 cc metal paste cartridges, a 7-inch touchscreen interface, AI camera monitoring and a HEPA + carbon filtration system to ensure clean operation are just a few of the user-focused features that MetalPrinting has added to the GAUSS MT90. Stainless steel, copper, titanium, nickel, iron, aluminum and tungsten are just a few of the metals that the printer can support with its exclusive "GaussInk" paste; customized formulas are available upon request.

The GAUSS MT90 is being proposed for functional prototypes, heat sinks, porous structures, micro-mechanical parts and research purposes where flexibility and ease of usage are crucial, but it is not meant for big structural components.

Regarding price, MetalPrinting has not released official data; prospective customers are encouraged to get in touch with the company directly for quotations. Although the total cost of ownership would depend on application and post-processing needs, some market experts speculate that metal ink cartridges might start around 150 dollars, which could reduce operational costs compared to standard metal feedstocks.
