Description

Technical Field

[0001] The present invention relates to the technical field of 3D printing, and in particular to a leveling mechanism for a 3D printer and a 3D printer. Background Art

[0002] 3D metal printer, also known as three-dimensional printer, is a machine of cumulative manufacturing technology, that is, rapid prototyping technology. It is based on a digital model file and uses special wax materials, powdered metal or plastic and other adhesive materials to print layers of adhesive materials to create three-dimensional objects. With the diversification of 3D printing materials and the innovation of printing technology, 3D printing not only shows extraordinary development potential in the traditional manufacturing industry, but also extends its charm to many fields closely related to people's lives, such as food manufacturing, clothing luxury goods, film and television media, and education.

[0003] A Chinese patent with announcement number CN210387580U discloses a leveling mechanism for a 3D metal printer work platform, which relates to the field of leveling technology. The leveling mechanism for a 3D metal printer work platform includes a base, a level, a first threaded rod, a second threaded rod and a third threaded rod. The front end of the base is provided with a first knob, a third knob and a second knob. The upper end of the base is provided with a slider. Four groups of support rods are fixedly installed on the upper outer surface of the slider. A pad is fixedly installed on the upper outer surface of the support rod. A workbench is fixedly installed on the upper outer surface of the pad. A circular opening is provided on the upper middle outer surface of the workbench.
