Description

Technical Field

[0001] This utility model relates to the field of 3D printer build platform technology, specifically a connection structure for a photopolymer 3D printer build platform. Background Technology

[0002] Photopolymer 3D printers use resin materials, which are cured layer by layer by ultraviolet light to ultimately build a model. An SLA 3D printer mainly consists of a resin tank, a build platform, a lift for moving the build platform up or down, a light source, and a pair of galvanometers. The printing process begins with pouring resin into the resin tank to form a layer between the build platform and the bottom. Once the build platform is in place, the light source shines through the transparent bottom of the tank to cure the resin. In a bottom-up SLA 3D printer, the light source is located below the resin tank, and the forming process appears as if the part is gradually pulled out of the resin tank.

[0003] Currently, in bottom-up SLA 3D printers, the top of the build platform is typically connected to the outer end of the lifting guide block via a connector. This traditional connection method is not very stable and can easily lead to a decrease in accuracy during the printing process. Therefore, there is an urgent need for an improved technology to solve this problem in the existing technology. Utility Model Content

The longitudinal vertical plate 3 has through holes at the corresponding positions of the groove 4. The bolts 7 pass through the through holes and are connected to the screw holes 11 on the corresponding side of the connecting rod 6, thereby realizing the connection and separation of the bolts 7 and the connecting rod 6.
