A 3d printing platform

Abstract

The invention provides a 3D (3-dimensional) printing platform. The 3D (3-dimensional) printing platform comprises a baseplate and a bottom plate, wherein connecting plates are mounted on left and right sides of the bottom plate and connected with the bottom plate to form a groove structure, and strip-shaped grooves are formed in opposite sides of the two connecting plates; more than two parallel balancing strips are fixed on the baseplate, ends of the balancing strips are exposed out of two opposite side edges of the baseplate and embedded into the strip-shaped grooves. By means of the balancing strips and the strip-shaped grooves as well as buckles and buckling grooves, the bottom plate and the baseplate are connected and fixed, and better horizontal stability of the printing platform is guaranteed; especially for a 3D model with large size in high-temperature printing forming space, the horizontal stability of a plane of the printing platform is guaranteed effectively with adoption of the metal balancing strips, the defects of warpage, staggered layers and the like of the model are further reduced, and printing of a high-quality 3D model finished product is realized; besides, the 3D printing platform is simple in structure and convenient to dismount, the balancing strips are recyclable, and the printing working cost is reduced.

Description

technical field [0001] The present invention relates to the technical field of 3D printing, more specifically, a 3D printing platform. Background technique [0002] During the 3D printing process, ensuring the stability and levelness of the printing platform is a key step in the pre-procedure work of 3D printing, and it is also one of the important criteria for determining the quality of the printed product. [0003] The traditional working platform is composed of upper and lower parts, one is the lower printing base, and the other is the upper substrate. The base plate in the working platform is fixed on the printing base plate, and the printed model is formed directly on the base plate. After printing, the base plate and the model printed on the base plate are disassembled together, and the model is removed from the base plate with corresponding tools. Then clean the surface of the substrate, and finally install the substrate back on the printing base plate of the 3D prin...
