Ohsung System launches GAUSS MT90 to bring office-safe metal printing

Ohsung System Co., Ltd. introduced the GAUSS MT90 at CES 2026, a compact metal paste 3D printer developed in collaboration with technology partner MetalPrinting. Built around Paste-based Metal Extrusion (PME), Instead of lasers or loose metal powders, the MT90 pushes metal-filled paste from proprietary GaussInk cartridges at room temperature, a workflow designed to cut dust and combustion hazards and make metal additive manufacturing more practical for offices and small labs.

The system supports multiple metal inks, including stainless steels, copper, and titanium formulations, and bundles hardware aimed at safer deployment: an integrated HEPA filter for particulate control and on-board cameras for monitoring prints. The MT90 is positioned as a democratizing step for metal AM, and the machine received a CES Innovation Award from Ohsung System Co., Ltd., highlighting its attention to safety and accessibility in the desktop metal space.

Practical realities remain. Parts come out of the printer in a paste-bound state and require post-print sintering in a furnace to reach final metal density and mechanical properties. That means access to a sintering furnace or an outsourced sintering service is still a gating factor for anyone planning to bring metal production in-house. The PME workflow removes the need to manage loose powders and high-powered lasers, but it does not eliminate post-processing time, furnace costs, or the need to plan for dimension change and finishing after sintering.

For bench-level makers, labs, and small shops this is a meaningful trade-off. The MT90 lowers the immediate barrier of powder handling and the regulatory headaches that come with metal powders, so you can prototype metal parts without a full powder-safe setup. However, verify your sintering options before committing to designs intended for structural use. Expect to iterate on prints and sinter cycles to dial in tolerances and material behavior, and consider local service bureaus or shared lab facilities if you lack an in-house furnace.

The community value is straightforward: more routes into metal printing without high-temperature lasers or powder containment. That opens possibilities for rapid prototyping of metal hardware, jigs, tooling inserts, and small-batch parts in environments where powder workflows were impractical. The MT90 also reinforces a growing trend toward cartridgeized feedstocks and enclosed, office-friendly metal systems.

The takeaway? The GAUSS MT90 makes metal AM more approachable, but it is not a turnkey replacement for full metal production. Plan for post-print sintering, confirm access to finishing resources, and treat the MT90 as a path to faster metal prototyping rather than instant final parts. Our two cents? Test small, use local sintering services if needed, and enjoy getting metal on the benchtop without suiting up for powder handling.
