Embodiment Construction

[0029] In order to make the technical problems, technical solutions and beneficial effects to be solved by the embodiments of the present invention clearer, the following combination Figure 1 to Figure 3 And embodiment, the present invention is described in further detail. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0030] It should be noted that when an element is referred to as being “fixed” or “disposed on” another element, it may be directly on the other element or be indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element. In addition, the connection can be used for both fixing and circuit communication.

[0031] It is to be understood that the terms "length", "width", "top", "bottom", "front", "rear", "left", "right",...

Abstract

The invention discloses a dual-wavelength metal 3D printing light path device and a 3D printing system. The device comprises a first laser device, a second laser device, a first collimation unit, a second collimation unit, a dichroic mirror, a galvanometer and a field lens; the wavelength of laser emitted by the first laser device is greater than that of laser emitted by the second laser device; and the first collimation unit, the dichroic mirror, the galvanometer and the field lens are sequentially arranged in the advancing direction of the laser emitted by the first laser device; the laser emitted by the second laser device can reach the dichroic mirror through the second collimation unit, and the dichroic mirror can enable the light spot of the laser emitted by the second laser device to surround the light spot of the laser emitted by the first laser device; and the absorptivity of metal to the laser emitted by the second laser device is greater than the absorptivity of the metal to the laser emitted by the first laser device. The system involves the device. The dual-wavelength metal 3D printing light path device and the 3D printing system can achieve fine printing.
