Description

Technical Field

[0001] The utility model relates to the technical field related to printer components, in particular to a heat dissipation base of a SLA light-curing printer. Background Art

[0002] SLA light-curing 3D printer is a 3D printing device based on light-curing technology. Its basic principle is to expose the photosensitive resin material to a light source of a specific shape, solidify the resin layer by layer and build a 3D model. In terms of product structure, the SLA light-curing 3D printer is mainly composed of a printer housing, a photosensitive resin material, a light source system, a motion system and a control system. Among them, the photosensitive resin material is used as a printing material to form a thin layer of liquid in the printer. The motion system consists of three axes, X, Y, and Z, which are used to control the position and height of the print head. The control system is the core of the entire printer and is responsible for controlling the coordinated operation of various systems. During the printing process, the laser or LED light source shines light on the photosensitive resin material according to a predetermined pattern and trajectory, causing it to solidify quickly. After the curing process is completed, the workbench drops one layer to prepare for the curing of the next layer. In this way, layers are stacked to form a complete 3D model.

[0003] The existing SLA light-curing printer base is used to install the printer components. Since there are many parts installed inside the base, including some electrical components, this installation is to save installation space and make full use of the internal space of the base. However, the electrical components generate heat when working and the heat is not easy to be discharged from the inside of the base. For this reason, we propose a SLA light-curing printer heat dissipation base. Utility Model Content
