Abstract

The invention relates to the field of 3D printing, in particular to polishing liquid for a metal 3D printing workpiece and a preparation method of the polishing liquid. The polishing liquid comprises inorganic acid, organic acid, fluoride, a ferric chloride solution and an amine compound. The polishing liquid has the advantages that the substances above are coordinated to achieve a synergic effect, and the polishing liquid can be effectively applied to the surface post-processing process of the 3D printing workpiece; the polishing liquid can be used as the polishing liquid special for processing the surface smoothness of a complex inner channel, the polishing liquid is reasonable in component, convenient to prepare and low in cost, and the workpiece alloy complex inner channel surface processed by the polishing liquid is low in roughness and good in smoothness and has an extremely good smooth and polished effect.

Description

technical field [0001] The invention relates to the field of 3D printing, in particular to a polishing solution for metal 3D printing workpieces and a preparation method thereof. Background technique [0002] Metal 3D printing is one of the additive manufacturing technologies. It is mainly used for the production of key components with high melting point, complex components and small batches but high value-added. Compared with the subtractive manufacturing of traditional manufacturing technologies, it has shorter production cycle and lower weight , high efficiency in manufacturing complex components, and the design is no longer limited by processing capacity. It is known as the most iconic production technology of the third industrial revolution. [0003] Generally, the surface roughness of metal 3D printing workpieces is usually around Ra6-30μm, which often does not meet the needs of the actual application of the workpiece. At present, for the metal 3D printing industry, t...
