[0002] 3D printing is the common name for additive manufacturing. Its core is the combination of digitalization, intelligent manufacturing and material science. In contrast to the traditional subtractive manufacturing method of cutting raw materials, the 3D printing process is like building a wall with bricks, adding materials layer by layer to eventually form a product.

[0003] The traditional 3D printer nozzle structure is relatively simple. When the optical material is ejected, the laser cannot move along, which results in the laser position not being in the same direction as the nozzle movement during use, resulting in poor light curing effect.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. Through the combination of the rotating assembly, the fixed ring and the light-transmitting chamber, when in use, the fixed motor drives the driven ring to rotate through the driving gear. Since a connecting ring is fixed on the top of the driven ring, the inside of the connecting ring is fixed to the outer wall of the nozzle through multiple bolts, so that the driven ring is fixed, and then the driving gear drives the fixed motor at the bottom to rotate around the outer wall of the nozzle, and then drives the fixed ring to rotate, so that the fixed ring drives the light-transmitting chamber to rotate, and the direction of the laser can be adjusted, so that the laser can be irradiated along the direction of movement of the nozzle, so that the material can be better consolidated.

[0017] 2. Through the combination of the adjustment component, the sliding component and the light-transmitting chamber, when in use, the driving motor drives the transmission gear to rotate through the driving gear, and then the transmission gear drives the internal lead screw to rotate, drives the internal wire ring to move, and then drives the sliding lens to move through the wire ring, so that the sliding lens can diffuse or converge the laser reflected by the fixed plate, and then adjust the light path. When the irradiation position needs to be adjusted, the light-transmitting chamber is rotated so that the fixed rack can be engaged with the fixed gear, and then the connecting ring is released by rotating the bolt, and the light-transmitting chamber can be moved upward, so that the fixed rack and the fixed gear move relative to each other, and then the fixed gear drives the connecting gear to rotate, and then drives the rotating plate to rotate, so as to adjust the reflection direction of the laser, which is very convenient.

[0018] 3. Through the combination of the fixing assembly, the fixing sleeve and the laser generator, the laser generator can be conveniently fixed and disassembled. By moving the pull rod to the side away from the fixing sleeve, the extrusion block is driven to move, so that the extrusion block is pulled out of the fixing sleeve. At this time, the laser generator can be placed inside the fixing sleeve. The magnet ring surrounding the outer wall of the laser generator and the top of the fixing sleeve are adsorbed on each other. The pull rod is loosened. Driven by the surrounding spring, the extrusion block fits tightly with the side wall of the laser generator and is then fixed. The operation is very simple. BRIEF DESCRIPTION OF THE DRAWINGS
