Technical Field
The utility model relates to the technical field of light path components, in particular to a light path component for a 3D printer.
Background
The SLA variable light spot printing technology uses large light spots inside a machined part, so that the efficiency is improved; when the outer surface of the part is machined, small light spots are used, and the surface quality is improved. The realization is that the diameter of the laser beam is adjustable through a group of adjustable beam expanding lenses, thereby realizing variable spot printing. This set of lenses needs to ensure a fairly high degree of coaxiality with the laser, otherwise the large and small spots are not concentric, which affects the operation. This is very cumbersome in the debugging process and requires a lot of experience to accomplish, and thus, an optical path component for a 3D printer is required.
