Specific embodiment
Below in conjunction with attached drawing the present invention is described in further detail, but this is merely exemplary, it is no intended to this
The protection domain of invention carries out any restrictions.
Referring to Fig. 1, Fig. 1 shows the device for implementing the bulky grain forming method based on light radiation partial melting of the present invention
Schematic diagram.The bulky grain forming method based on light radiation partial melting of the present invention is as follows：
Mobile platform 1, cradle head mechanism 2 and radiating light source 3 have been collectively constituted into Optical irradation system, propped up on mobile platform 1
Support sets cradle head mechanism 2, and the front end of cradle head mechanism 2 is rotatably arranged radiating light source 3, and it is certain high that radiating light source 3 possesses irradiation
The ability of the lower arbitrary region of degree.The mode that power supply adds light source can be used in Optical irradation system, and reflecting focal light path can also be used
