3D printing assembly, printing platform and leveling method of platform

Abstract

The invention discloses a 3D printing assembly, a printing platform and a leveling method of the platform, and belongs to the technical field of 3D printing, the 3D printing assembly comprises a stand column, a second guide rail is arranged on the front surface of the stand column, a sliding block is slidably connected to the second guide rail, a cantilever is welded to the front surface of the sliding block, a rack is arranged on the cantilever, and a driving box is arranged on the rack; a machine head is fixedly installed at the front end of the driving box, a balancing weight is arranged at the end, close to the stand column, of the cantilever, and a limiting column movably penetrates through the center of the balancing weight. Leveling of the 3D printer platform can be achieved through the leveling mechanism, leveling is divided into four directions, namely the four corners of the platform, leveling is completed through the leveling blocks, the temperature of the printing platform is changed in a cold and hot alternating mode, and therefore a printed finished product and the printing platform are automatically separated due to the temperature difference, and the printing efficiency is improved. Horizontal and vertical movement of the printer head is achieved through the two sliding rails, and transverse, longitudinal and vertical adjustment is achieved.

Description

technical field [0001] The invention belongs to the technical field of 3D printing, and in particular relates to a 3D printing component, a printing platform and a leveling method for the platform. Background technique [0002] 3D printer is a machine of rapid prototyping technology. The raw material is generally thermoplastic material, which is fed in filament form. The material accumulates along the cross-sectional contour and filling track of the part. The molten material solidifies rapidly and condenses with the surrounding materials. The printer reads Take the cross-section information in the file, print these sections layer by layer with liquid, powder or sheet materials, and then glue the cross-sections of each layer in various ways to create a solid body. The characteristic is that it can create objects of almost any shape. Traditional manufacturing techniques such as injection molding can mass-produce polymer products at a lower cost, while 3D printing technology ca...

Problems solved by technology

[0004] Aiming at the problem that the printed finished product will stick to the platform due to the temperature during the printing process of the existing 3D printer, which makes it difficult to detach. Automatic separation between finished product and printing platform due to temperature difference
