The PECAM invention is a desktop metal additive manufacturing machine that produces a wide range of composites at near-room temperatures, under ambient conditions, and with a fraction of the energy required compared to laser metal sintering-based additive manufacturing. A major roadblock to realizing PECAM was particle clogging at the nozzle exit. We invented a novel engineering mechanism for continuously dispensing metal powder at a controllable rate into aqueous media from the nozzle of the PECAM system, without clogging (Pending U.S. Patent Application for Apparatus and Method for Wet Powder Dispensing for Low Temperature Metal 3D Printing, Patent Application #20240399463). PECAM, with a novel powder-dispensing method, represents a critical advancement in the field of metal additive manufacturing, offering a cheaper (like a plastic 3D printer) system that operates near room temperature and yields unprecedented composites in which particles and coating metals can be chosen arbitrarily. This paper discusses the use of a reciprocating-rotating system to transport metal powder for PECAM processes. The proposed system introduces a mixing motion that facilitates the seamless transportation of particles through channels inside a liquid medium while minimizing issues such as particle choking and clogging. A particle transport simulation using Altair EDEM is conducted to assess the forces involved and calculate the system's flow rate. The findings from this study contribute to enhancing the efficiency and reliability of metal powder transportation for the wide range of applications of PECAM. This study will also provide an initial platform for developing the Digital Twin framework to further advance and apply PECAM-impacting metal additive manufacturing.
