3D printer leveling device

Abstract

The invention discloses a printing platform leveling device for a stereolithography 3D printer. The 3D printer leveling device comprises a mechanical module and a circuit module, wherein the mechanical module comprises a forming tray and a photosensitive resin groove; the forming tray is made of a metal material, is an excellent electric conductor and is directly connected with a power supply through a guide line and a guide line clamp; the photosensitive resin groove is connected with the power supply through a square sheetmetal and a guide line. The leveling mechanism can be used for leveling the forming tray and the resin groove to enable the distance between each of four corners of the forming tray and the bottom of the resin groove to be uniform so as to ensure that a printed model can be successfully adhered to the forming tray and ensure that the thickness of each curing layer during the printing process is uniform. The leveling mechanism is detachable and can be removed after leveling is performed each time, so that the size of the printer body is reduced, a Dupont plug is plugged during next leveling, and the situation that the resin groove is parallel to the forming tray during each printing process is ensured; therefore, the long-term printing accuracy is ensured.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a 3D printing leveling device, which is suitable for leveling SLA printers and 3DP printers. Background technique [0002] 3D printing technology, also known as Rapid Prototyping Manufacturing (RPM) or additive manufacturing technology, involves mechanical engineering, material engineering, digital control, reverse manufacturing, CAD technology, and computer technology. The basic principle of 3D printing technology is "print layer by layer, layer by layer superposition", that is, first generate a 3D model through CAD software, and then slice it layer by layer and plan the path by the host computer slicing software (such as cura, Repetier-Host, etc.) , import the generated G-code file to the lower computer controller, and then the controller controls the 3D printing device to reproduce the 3D solid model layer by layer. [0003] With 3D printing rapid prototyping technology a...
