However, the present application can be implemented in many different forms and should not be interpreted as being limited to the embodiments shown herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of this application more thorough and complete.

[0022] It should be noted that when an element is described as "attached" to another element, it can be located directly on top of the other element, or there can be an intervening element. Similarly, when an element is described as "connected" to another element, it can be directly attached to the other element, or there can be an intervening element.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as they would be generally understood by a person skilled in the technical field of the present application. The terminology used herein in the description of the present application serves only to describe specific embodiments and is not intended to limit the present application.

[0024] With reference to Fig. According to embodiments 1 to 6 of the present application, the 3D printer comprises a print platform arrangement 1, a first stroke arrangement 2, a second stroke arrangement 3, a first drive component 4, and a second drive component 5. The print platform arrangement 1 serves to receive the material extruded by the print head arrangement 6, and the print platform arrangement 1 has a first side 101 and a second side 102, which are arranged opposite each other. The first stroke arrangement 2 is articulated to the first side 101 of the print platform arrangement 1. The second stroke arrangement 3 is articulated to the second side 102 of the print platform arrangement 1. The first drive component 4 is connected to the first stroke arrangement 2 for drive purposes, and the first drive component 4 is used to drive the first stroke arrangement 2 and move it in a first direction.The second drive component 5 is connected to the second stroke assembly 3 and is used to drive the second stroke assembly 3 and move it in a first direction. The first drive component 4 and the second drive component 5 can each drive the first stroke assembly 2 and the second stroke assembly 3, respectively, to move them and adjust the angle α between the print platform assembly 1 and the print head assembly 6.

[0025] In one embodiment of the present application, it is provided that the first drive component 4 and the second drive component 5 can each drive the first stroke arrangement 2 and the second stroke arrangement 3, such that the first stroke arrangement 2 and the stroke arrangement 3 have a height difference in the first direction, that is, the first side 101 and the second side 102 of the print platform arrangement 1 have a height difference in the first direction, so that the print platform arrangement 1 is inclined relative to the print head arrangement 6. The print head arrangement 6 can directly print a model with a specific angle of inclination between itself and the print platform arrangement 1, thus achieving support-free printing. The angle α between the print platform arrangement 1 and the print head arrangement 6 can be adjusted by the first drive component 4 and the second drive component 5, which facilitates use and improves printing efficiency.which reduces printing costs and demolding difficulties.

[0026] For example, the printhead assembly 6 can extrude material along a first direction, where the first direction is a vertical direction, i.e., a Z-direction. The first drive component 4 and the second drive component 5 can each drive the first stroke assembly 2 and the second stroke assembly 3, respectively, so that the first stroke assembly 2 and the second stroke assembly are at the same height, thus aligning the first side 101 and the second side 102 of the print platform assembly 1, and therefore making the print platform assembly 1 parallel to the horizontal plane, that is, perpendicular to the first direction. With reference to Fig. 1 to Fig. The first drive component 4 and the second drive component 5 can each drive the first stroke assembly 2 and the second stroke assembly 3, respectively, so that the first stroke assembly 2 and the second stroke assembly 3 are at different heights. This results in the first side 101 and the second side 102 of the print platform assembly 1 being at different heights, and the print platform assembly 1 is therefore inclined relative to the horizontal plane. The angle α between the print platform assembly 1 and the printhead assembly 6 can be adjusted by the first drive component 4 and the second drive component 5 according to the actual conditions.

Alternatively, the first drive component 4 is used to drive the two first lifting parts 201 so that they each move along the first direction, that is, the two ends of the first side 101 of the printing platform arrangement 1 can be at different heights, thereby further increasing the adjustment range of the tilt angle of the printing platform arrangement 1.
