3D printing (3DP) is a kind of rapid prototyping technology, also known as additive manufacturing. It is based on digital model files, using powdered metal or plastic and other bondable materials to print layer by layer. The technique of constructing objects.
3D printing is usually achieved by using digital technology material printers. It is often used to make models in mold manufacturing, industrial design and other fields, and then gradually used in the direct manufacturing of some products. There are already parts printed using this technology. The technology has applications in jewelry, footwear, industrial design, architecture, engineering and construction (AEC), automotive, aerospace, dental and medical industries, education, geographic information systems, civil engineering, guns, and other fields.
3D printed workpieces are usually more complex cavities that cannot be completed by traditional machining. Due to the large powder particles, the printed workpiece has a rough cavity, and the interior of the irregular cavity cannot be polished by manual polishing and traditional mechanical polishing. Claim. The interior of the cavity cannot be polished by manual polishing and traditional mechanical polishing. Fluid polishing utilizes the fluidity of the abrasive, and the semi-solid plasticity achieves the internal polishing of complex cavities.
