Description

Technical Field

[0001] This utility model relates to the field of 3D printing technology, and in particular to a heated bed plate for a 3D printer. Background Technology

[0002] During the printing process of a 3D (Fused Deposition Modeling) printer, the printing material undergoes a process of melting at high temperatures and then cooling and solidifying. Due to the inherent thermal expansion and contraction of materials, this can easily cause edge warping in the printed product. Therefore, 3D printers are generally equipped with a heated bed for placing the printed product.

[0003] Currently, the heated bed of a 3D printer is in direct contact with the printed artwork. After printing, the artwork is removed from the heated bed primarily through two methods: direct removal or peeling with a tool. This setup has two drawbacks. First, the artwork can be damaged during removal due to excessive or uneven force, or improper tool handling. Second, this setup and method make the removal process inconvenient and inefficient. Furthermore, using tools to peel the artwork can easily scratch the heated bed, shortening its lifespan. Summary of the Invention
