What are the advantages of 3d printing compared with traditional printing methods?

The efficiency of 3d printer in manufacturing handboards is about twice as high as that of traditional mode, and more importantly, it saves manpower and time costs.

3D printing (3DP) is a rapid prototyping technology, also known as additive manufacturing. It is a technology of printing objects layer by layer based on digital model files and using adhesive materials such as powder metal or plastic.

3D printing is usually realized by a material printer using digital technology. It is often used in mold manufacturing, industrial design and other fields to make models, and then gradually used in the direct manufacturing of some products. Parts already printed with this technology. This technology has been applied to jewelry, footwear, industrial design, architecture, engineering and construction (AEC), automobile, aerospace, dentistry and medical industry, education, geographic information system, civil engineering, guns and other fields.
