South Korean steel 3D printing producer MetalPrinting has introduced the novel GAUSS MT90 steel paste 3D printer at CES 2026.
Not like customary techniques utilizing lasers, powder beds, or binder spraying, the MT90 operates with paste based mostly steel extrusion (PME), through which steel powder is formulated right into a paste and extruded by way of a nozzle at room temperature. This shifts a number of sensible constraints away from free powder dealing with and high-energy warmth sources, putting extra of the method inside a closed, managed desktop machine quite than a devoted industrial setup.
How the GAUSS MT90 paste steel AM system works
As detailed by the producer, materials for the machine is available in sealed syringe sort cartridges, that are slotted into the printer and swapped when wanted. That cartridge strategy permits totally different metals for use on the identical system with out the cleanup routines usually related to powder dealing with.
Moreover, the fabric lineup consists of chrome steel, copper, titanium, iron, nickel, aluminum, tungsten, and customized formulations. As soon as a component is printed, it nonetheless has to undergo a separate sintering step, the place the steel particles are fused right into a strong half.
Bodily, the MT90 is aimed on the desktop class. It has a most construct quantity of 85 × 85 × 60 mm, a machine measurement of 420 × 420 × 500 mm, and a listed weight of 30 kg. Nozzle diameters vary from 0.2 to 1.4 mm, which permits the identical machine to be configured both for smaller, extra detailed components or for quicker materials deposition.
Operation is dealt with by way of a 7-inch touchscreen and a guided workflow that steps by way of loading materials, checking viscosity, and beginning the print. The printer additionally makes use of a coloration coded standing mild system and consists of options equivalent to an Auto Mattress Detach System and a Fast Begin Mode, each lined by PCT patent filings.
One of many said objectives of the MT90 is to make steel 3D printing extra suitable with peculiar workspaces. The corporate lists working noise at about 40 dB, roughly within the vary of frequent workplace or residential background noise, and the system is supplied with a built-in HEPA carbon filter.
The intent is to permit the machine to run in environments the place standard powder mattress fusion (PBF) or binder jet techniques would usually require extra security infrastructure.
By way of functions, MetalPrinting is positioning the MT90 for small useful components quite than giant structural parts. As an example, the system is appropriate for warmth sinks and thermal administration components, porous buildings and catalyst helps, micro scale mechanical parts, and small medical or digital components.
The 3D printer can be aimed toward prototyping and analysis use, the place materials modifications are frequent and batch sizes are restricted.
