(not shown), laser generator are connected with laser beam emitting device 150 by optical fiber.In one Laser Driven mechanism 100 of setting
In the case of, the print range of 3D printer 200 is a fan annular.
Figure 10 is another arrangement mode of Laser Driven mechanism 100 in the embodiment of the present invention.Figure 10 is refer to, in this hair
In bright other embodiment, multiple Laser Driven mechanisms 100 of 3D printer can along the circumferential direction arrange and form circle
Orbital path, enable 3D printer that there is the print range of an annular.It is 4 Laser Driven mechanisms 100 shown in figure
(the guide rail extension angle of each Laser Driven mechanism 100 is 90 ° herein) is slapped together, in other embodiments, can basis
The guide rail extension angle of each Laser Driven mechanism, select the Laser Driven of different numbers (such as 2,3 or more than 4)
The overall structure to form annular is pieced together by mechanism.
The Laser Driven mechanism 100 of the present embodiment and the operation principle of 3D printer 200 are：
The rail assembly 110 of Laser Driven mechanism 100 including arc, female car 120, sub- car 140 and it is arranged at sub- car 140
Laser beam emitting device 150, female car 120, can be along interior guide rail 111 and outer in the presence of interior drive mechanism and outer drive mechanism
Guide rail 112 does movement in a curve.The cooperation of sliding part 127 and slide rail causes female car 120 to run more on rail assembly 110
Add stabilization.Sub- car 140 is connected by the fit system of sliding block-chute with female car 120, and can be in sub- car drive mechanism 130
Moving radially along guide rail under driving.In this way, the laser beam emitting device 150 on sub- car 140 just has the motion of a fan annular
Plane, laser beam emitting device 150 can be in the range of the plane of movement of fan annular to the dusty material on lower work platform 210
It is sintered or melts, therefore the 3D printer 200 has larger print range.
In summary, Laser Driven mechanism of the invention includes rail assembly, female car, sub- car and laser beam emitting device.
Female car is movably connected on rail assembly, and the guide rail of rail assembly provides the motion path of an arc for female car.Sub- car activity
Be connected to female car, and can relative to female car radially moving in arc-shaped guide rail, laser beam emitting device is arranged on sub- car.This
The structure of sample allow laser beam emitting device with female car, sub- car movement and in a difference fanned on anchor ring (or anchor ring)
Position selection is printed, therefore has larger print range.
The 3D printer of the present invention includes above-mentioned Laser Driven mechanism and workbench, and laser beam emitting device will can swash
The table top of light directive workbench, the dusty material that can be pointed on table top are sintered or melted.As a result of above-mentioned
Laser Driven mechanism, the scope of activities of laser beam emitting device is larger, therefore has larger print range.
The preferred embodiments of the present invention are the foregoing is only, are not intended to limit the invention, for the skill of this area
For art personnel, the present invention can have various modifications and variations.Within the spirit and principles of the invention, that is made any repaiies
Change, equivalent substitution, improvement etc., should be included in the scope of the protection.
