The prior SLA photocuring 3D printer is a cantilever type printing substrate, and the printing substrate with the structure has the following problems:

1. the cantilever type printing substrate can not be parallel to the opposite surface (liquid photosensitive resin horizontal surface) with high precision during assembly;

2. the cantilever type printing substrate is continuously increased along with the weight of a printing product in the printing process, and the parallelism error of the opposite surface (the horizontal surface of the liquid photosensitive resin) of the printing substrate is also continuously increased;

3. since the level of the opposite surface (liquid photosensitive resin level) is a natural phenomenon, the tolerance of assembling the cantilever type printing substrate to be parallel to the opposite surface can meet the design technical requirements is completely unavailable;

4. the parallelism of the opposite surfaces is obtained by increasing the number of layers of the printing supports, (generally 70 to 100 layers of N multi-layer supports are printed before products are printed, and the supports are removed at last) a large amount of expensive materials are wasted;

5. after the printing in the supporting stage, the problem that the printing substrate is parallel to the opposite surface along with the increase of the weight of the product is solved without a method, the weight is generally controlled, and the performance of the whole machine cannot be well exerted.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to the above-mentioned among the prior art not enough, provide a SLA photocuring 3D printer both ends slip fulcrum and print the base plate to solve the problem of printing the parallel of base plate in the opposite face.

In order to achieve the purpose, the utility model adopts the technical proposal that:

the inner guide plate is fixed on the bracket through the adapter plate, and the printing substrate is borne above the bracket; the two outer guide plates are fixed on a guide rail base of the printer.

Preferably, two guide rod sliders are arranged between the inner guide plate and the outer guide plate.

Preferably, the leader slider is fixedly mounted on the inner guide by bolts.

Preferably, the two sets of guide plates are symmetrically fixed on both sides of the printing substrate.

Preferably, the linear bearing moves on the linear guide rail, so that the guide rod sliding block moves on the linear guide rail.

The utility model provides a SLA photocuring 3D printer both ends slip fulcrum and print the base plate, have following beneficial effect:

the utility model realizes the lifting movement of the printing substrate by arranging the sliding guide plates on the two sides of the printing substrate; the two inner guide plates and the bracket are matched to bear the printing substrate, so that the printing substrate and the opposite surface are ensured to be horizontal; and the two outer guide plates are respectively fixed on two sides of the guide rail base, so that the horizontal stability of the printing substrate is further improved.

Detailed Description

The following description of the embodiments of the present invention is provided to facilitate the understanding of the present invention by those skilled in the art, but it should be understood that the present invention is not limited to the scope of the embodiments, and various changes may be made apparent to those skilled in the art within the spirit and scope of the present invention as defined and defined by the appended claims.

According to an embodiment of the application, referring to fig. 1, the SLA photocuring 3D printer of the present scheme has a two-end sliding fulcrum printing substrate 6, which includes a printing substrate 6, a bracket 5 and two sets of guide plates.

Every group baffle all includes an outer baffle 1 and an interior baffle 2, sets up two piece at least guide bar sliders 3 between interior baffle 2 and the outer baffle 1, and the quantity of guide bar slider 3 is decided according to actual demand, and the preferred two guide bar sliders 3 of this embodiment.

Wherein, the inner side of the outer guide plate 1 is provided with a linear guide rail 8 which is used for matching with the guide rod sliding block 3 in parallel, and one end of the guide rod sliding block 3 is fixedly arranged on the inner guide plate 2; the upper part of the guide rod sliding block 3 is fixed on a linear guide rail 8 in a sliding mode through a linear bearing 7, and the linear bearing 7 moves on the linear guide rail 8 to achieve the movement of the guide rod sliding block 3 on the linear guide rail 8.
