"All-In-One" Multi-Material Additive Manufacturing
& Microwave Digital Casting System
Features & Benefits
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 that is cost-effective, safe to handle, and environmentally friendly.
No Debinding and Fast Microwave Sintering
Metallum3D has developed a new patent-pending microwave sintering process that uses microwave energy and a granular susceptor material to instantaneously heat the entire sintering volume, resulting in a reduction in sintering time of up to 90%. 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.
Microwave Digital Casting
In sinter-based metal additive manufacturing, there are certain metals such as aluminum that are difficult to sinter due to the presence of an oxide layer in the metal powder which inhibits sintering. To solve this problem, our Microwave Digital Casting process uses a 3D printed ceramic shell mold that is filled with a metal powder. The ceramic mold with metal powder is embedded in our granular susceptor material and heated in our microwave furnace until the metal powders melt to form a casted part.
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 additive manufacturing system in the market. 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.
Microwave Digital Casting
The Metallum3D Microwave Digital Casting process combines our pellet extrusion 3D printer, ceramic 3D printing materials, and microwave furnace to provide a fast and flexible process for the rapid manufacture of metal parts. The first step in our Microwave Digital Casting process is to 3D print a ceramic shell mold of the metal part to be made. The second step is to fill the ceramic mold with the desired metal powder. The third step is to place the ceramic shell mold in our microwave furnace and embed it in our granular susceptor material. The fourth and final step is to use our microwave furnace to apply microwave energy to rapidly heat and melt the metal powder within the mold to form a casted part.
