Problems solved by technology

The most popular on the market is material extrusion (FDM) molding machine, also known as fused deposition molding machine. For 3D printers based on this principle, the printing platform leveling method usually adopts the soft leveling method of screws and springs. There is a certain degree of vibration and jitter in this leveling method, which will affect the printed product, increase the size error of the product, and make the surface rough

Abstract

A rigid leveling mechanism for the printing platform in a 3D printer. When leveling is required, first remove the printing platform, loosen the small screws and locking nuts, and properly adjust the three leveling screws so that the backing plate is relatively parallel to the printing head, and the tightening is small. Screws and locking nuts, and then place the printing platform on the backing plate through the upper and lower magnets, so that the printing platform and the printing head are relatively parallel. During the leveling process, the backing plate will not vibrate and shake when the leveling screw is turned, which is convenient for the leveling instrument to work quickly. After leveling the backing plate, during the process of tightening the small screws, the backing plate is basically no longer displaced relative to the leveling screws. After tightening the small screws, the backing plate and the print head can be ensured to be relatively parallel. The invention improves the leveling mechanism of the printing platform in the 3D printer. After leveling and locking, the printing platform does not vibrate and shake during the printing process, which is beneficial to improve the dimensional accuracy and surface smoothness of the printed product, and the leveling It is easy to operate, economical and practical, simple in structure and reasonable in design.

Description

technical field [0001] The invention belongs to the technical field of 3D printers, and particularly relates to a rigid leveling mechanism of a printing platform in a 3D printer. Background technique [0002] The core of 3D printing is to convert the complex 3D shape of the workpiece to be formed into a simple combination of 2D sections through slicing processing. According to the 3D computer-aided design (CAD) model of the workpiece, the 3D workpiece is directly formed on the computer-controlled additive manufacturing equipment. . There are currently 5 types of 3D printers: 1. In-container photopolymerization (SLA) molding machine, which uses a laser beam to solidify liquid photosensitive resin; 2. Powder bed sintering / melting (SLS / SLM / EBM) Forming machine, using laser beam / electron beam sintering / melting powder forming; 3. Lamination type (LOM) forming machine, forming sheet by laser beam, knife or ultrasonic; 4. Binder jet type (3DP) Forming machine, use the nozzle to s...
