3D printing equipment with humidity control and edge warping prevention functions

Abstract

The invention relates to 3D printing equipment with humidity control and edge warping prevention functions. The 3D printing equipment comprises a main body, wherein a PLC (Programmable Logic Controller), a printing box, a moving box, an ascending and descending box and a regulating mechanism are arranged in the main body; an ascending and descending mechanism is arranged in the ascending and descending box; a separation mechanism is arranged in the moving box; the regulating mechanism comprises an air blower, a drying unit and a humidification unit. The 3D printing equipment with the humiditycontrol and edge warping prevention functions has the advantages that through the regulating mechanism, the humidity of air inside the 3D printing equipment can be maintained to be 20 percent to 80 percent; the short circuit of the 3D printing equipment caused by the occurrence of dew formation phenomenon in the 3D printing equipment due to too great humidity is prevented, or the misoperation of the 3D printing equipment caused by electrostatic interference generated due to too low humidity is prevented; moreover, through the ascending and descending mechanism, the 3D printing equipment can spray and coat water soluble glue on the upper surface of a platform; the product edge is stuck; the product edge warping is prevented.

Description

technical field [0001] The invention relates to the field of 3D printing equipment, in particular to a 3D printing equipment with functions of humidity control and edge warping prevention. Background technique [0002] 3D printing is a kind of rapid prototyping technology. It is a technology based on digital model files and using bondable materials such as powdered metal or plastic to construct objects by layer-by-layer printing. 3D printing is usually realized by using a digital technology material printer (3D printer), which is mainly used to manufacture models, and is gradually used in the direct manufacture of some products. [0003] The plastic will shrink during the cooling process. When the working area is small, the impact of shrinkage is not obvious, but when printing larger products, the shrinkage generated per unit area accumulates, and the pulling force generated inward becomes considerable. Not only that, but the relative humidity of the air in the existing 3D ...

AI Technical Summary

Problems solved by technology

[0003] The plastic will shrink during the cooling process. When the working area is not large, the impact of shrinkage is not obvious, but when printing larger products, the shrinkage per unit area accumulates, and the pulling force generated inward becomes quite large. Not only that, but the relative humidity of the air in the existing 3D printing equipment should not exceed 80%. If the humidity is too high, there will be condensation in the existing 3D printing equipment, resulting in the existing 3D printing equipment. The components in the printing equipment are damp and deteriorated, causing the existing 3D printing equipment to be damaged due to short circuit, and the relative humidity should not be lower than 20%, otherwise, electrostatic interference will be generated due to excessive drying, causing the existing 3D printing equipment to malfunction
