According to the actual use requirements, select materials. 2) Check the wall thickness you designed to ensure that the minimum wall thickness requirements are met. 3) If your design is hollow, be sure to design an escape hole large enough. 4) If there are independent columns in your design, be sure to meet the minimum wall thickness requirements. 5) If there are convex or concave details in your design (such as convex or concave characters), be sure to meet the minimum width and height requirements. 6) If there is a sharp part in your design, the angle of this part needs to meet the minimum requirements. 7) If your design contains multiple parts.

3D printing is a rapid prototyping technology. It is a technology based on digital model file, using adhesive materials such as powder metal or plastic, and constructing objects by printing layer by layer. 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.
