Hybrid fabrication (metal hybrid laser fabrication)
Hybrid metal 3D printing is the latest machining technology, developed here in Japan. It fabricates components from bottom to top through repeated laser irradiation and triaxial cutting. The process is outlined below.
Hybrid fabrication process cycle
Video of recoating process
The recoating blade lays down a uniform layer (as little as 25 μm thick) of powdered metal materials onto the work table, at high speed. Recoating takes place repeatedly from both the left and right sides.

■Laser irradiation process
Irradiation of a cross-section of the part at high speed (700 mm /sec - 3000 mm /sec) melts and solidifies the layer of powdered metal materials. These layers are built up from bottom to top.
Video of cutting process
A spindle is used to cut the part as appropriate, timed precisely so that the effective length of the blade reaches the places it needs to reach or the entire surface of the part.
The three actions above can be automated using processing data from OPM’s exclusive CAM system, so that operators themselves do not have to deal with the complex processes employs.
