All steps, such as laser sintering powder additive manufacturing, component unpacking, powder filtration, mixing, conveying and dust collection，are finished in different kinds of equipment. The transfer of powder among different kinds of equipment possibly causes leakage and needs a lot of energy and time of operators. Although operators can operate the equipment and treat the powder skillfully, the treatment of powder in SLS additive manufacturing needs both skill and physical strength. The Parts & Powder  Processing Station (PPS) researched and developed by TPM3D team for 3 years completely eliminates the impact of powder leakage on the environment and makes the part cleaning and powder treatment easy. Users can save time and efficiently finish mass production tasks. The combination of PPS and TPM3D S serials laser sintering system can realize the clean production mode and can retain the traditional manual powder feeding mode. The printing materials can be easily replaced if necessary.
