3D (three-dimensional) printing platform with adjustable angle

Abstract

The invention discloses a 3D (three-dimensional) printing platform with an adjustable angle. A shell is fixed to a base; a first gear shaft is horizontally arranged on the shell; branch shafts are fixed to the two sides of the first gear shaft; the two sides of a central bogie are movably arranged on the two branch shafts in a sleeving manner; the top of the central bogie is fixedly connected to the bottom surface of a platform; a swinging bogie is arranged on the shell; the two ends of the swinging bogie are articulated with side plates of the two sides of the shell; a supporting shaft and asecond gear shaft are coaxially arranged, are perpendicular to the axis of the first gear shaft and are located on the same plane; a strip groove is formed in the top of the swinging bogie; and a connecting rod penetrates through the strip groove and can move along the strip groove. The precise control and automation of the leveling of the 3D printing platform can be realized; the angle of the platform is controlled in the printing process; and the 3D printing platform can meet the requirements of different layering methods such as tilt printing, has strong adaptability, and improves the surface accuracy of a printing model.

Description

technical field [0001] The invention relates to a 3D printer platform, especially for a 3D printing self-adaptive tilt layering method, the platform can adjust the angle of the platform accordingly according to the angle of the tilt layer. Background technique [0002] 3D printing is a rapid prototyping technique that creates parts by building up layers. Before printing the model, the model is first layered. Because different parts of the model have different requirements for printing accuracy, the accuracy requirements for layering are also different, and different parts of the part have different layering thicknesses and layering directions. Therefore, being able to change the direction of the platform accordingly during the printing process is of great significance to the printing results. [0003] For 3D printers with FDM (Fused Deposition Modeling) printing method, due to factors such as vibration, the platform may be tilted, forming a certain inclination angle with t...

AI Technical Summary

Problems solved by technology

If the platform is not adjusted to the proper angle, the nozzle may collide with the platform, causing damage to the nozzle

Improper angle of the underlying platform may cause problems such as poor bonding between the model and the platform, and edge warping. The level of the platform is an important factor affecting the printing result
