Positioning reference design of 3D printed parts: machining allowance and clamping plan selection

Introduction: Positioning datum is the basis of precision manufacturing After 3D printing parts are printed, they often require secondary processing—CNC finishing, drilling, tapping, assembly, etc. These subsequent processes all rely on accurate positioning datum (Datum). Different from traditional processing, the reference plane of 3D printed parts is usually not formed by processing, but printed, which brings a series of challenges such as reference accuracy, repeated positioning and design annotation. If the positioning reference design is unreasonable, even if the printed part itself is very precise, there may be deviations in subsequent processing. This article will systematically introduce the positioning datum of 3D printed parts...
