Next Generation Sinter Based
Multi-Material Additive Manufacturing System

Metalum3D Additive Manufacturing System October 2021 Update.png



Open Multi-Material 3D Printing

The Metallum3D additive manufacturing system uses materials in pellet form. Pelletized materials are the standard in the polymer industry. For plastic and flexible materials, there are thousands of exiting suppliers worldwide that supply these materials providing users of our system with an almost unlimited choice of materials. For metal and ceramic materials, Metallum3D has developed a water- gelation material formulation in pellet form that is cost-effective, safe to handle, and environmentally friendly. 


No Debinding and Fast Sintering 

Metallum3D has developed a new patent-pending microwave sintering process that uses microwave energy and a granular susceptor material to rapidly and directly convert microwave energy into heat, which instantaneously heats the entire sintering volume, resulting in a significant reduction in sintering time. Our microwave sintering process is up to 9 times faster for large parts and up to 12 times faster for small parts when compared to existing conventional sintering processes. In our system, metal and ceramic 3D printed parts go directly from the 3D printer to our microwave sintering furnace without the need for a debinding step.


Affordable Price


Low Cost of Ownership

Our "All-In-One" additive manufacturing system is more affordable and has a lower cost of ownership than any other competing sinter-based additive manufacturing system in the market. Our system price is up to two-thirds less than competing systems and our system is designed to be installed, maintained, and updated by the user. All system operating parameters are open and can be changed by the user, there are no software locks. Additionally, no expensive annual service contracts or software subscriptions are required to operate our system.

Multi-Material Pellet Extrusion

To provide an open materials platform with multi-material capabilities, Metallum3D has developed a patent-pending melt pump pellet extruder that accepts material in pellet form. Our extruder combines a zero-compression feed screw with a miniature positive displacement gear pump and three independent heating zones, to precisely control the extrusion and retraction of melted materials flowing through the nozzle. This melt pump extruder allows our system to 3D print parts with plastic and flexible materials and 3D print and microwave sinter parts with metal and ceramic materials.

Microwave Sintering Process

F2AST stands for "Far Field Area Sintering Technology". Our patent-pending F2AST microwave sintering technology uses non-resonant, cross-polarized, slotted waveguides and a granular susceptor material to evenly distribute microwave energy during sintering, resulting in rapid and even heating throughout the sintering volume. When compared to conventional sintering technologies, F2AST sintering provides an order of magnitude performance improvement by reducing sintering process times from days to hours.
