Mechanism of 3D printing using super-alloy wire
The 3D printer feeds a wire from the nozzle and laminates the molten metal to form the component shape. This system can produce a relatively large part in a short time, for example, for the repair of an aircraft engine or valve.
Mitsubishi Power’s patented technologies and processing technologies have to solveed various issues in using high-strength super-alloy wires for AM applications.
- Mitsubishi Power’s patented technology (MH Process) has enabled the production of high-strength wires that could not be manufactured by using conventional technologies.
- In addition to welding repairs, High-strength super-alloy wires can be used by Direct Energy Deposition (DED)-system 3D printers.
- For small-lot production of made-to-order materials, please contact our company. We deliver products in the following specification range: Rod shape: φ1.0 to 5.0 mm, wire shape: φ1.0 to 1.6 mm x 10 m or more.
