AI Technical Summary

Technical Problem

The printing panel of a 3D printer is prone to deformation during use due to its poor rigidity, which affects the print quality.

Method used

A heated bed was designed, including a bed board, heating elements and supporting components. The heating uniformity is improved by rationally arranging the heating sections and heat-conducting materials, and the rigidity and stability of the bed board are enhanced by an elastic leveling device and locking components.

Benefits of technology

It improves the flatness and rigidity of the printed panel, reduces deformation, and enhances the quality of 3D printing.

Abstract

本申请公开了一种热床和3D打印机，热床包括床板和条状的加热件，加热件包括第一加热段、第二加热段、第三加热段、第四加热段、第五加热段和第六加热段，第一加热段、第二加热段、至少一个第三加热段和第四加热段沿第一平面方向依次间隔排布并且均沿第二平面方向延伸设置，第一平面方向与第二平面方向相交，第一加热段邻近床板的一侧边设置；第五加热段与第二加热段在靠近床板的中心的一端相互连接，第六加热段与第五加热段沿第二平面方向间隔设置；第六加热段与靠近第一加热段的第三加热段，在靠近床板的中心处相互连接。如此，各个加热段形成非对称布置结构，并且可以使得加热件对床板的加热更加均匀，从而可以提高打印质量。
