Abstract:Three-Dimensional Printing (3DP) is an additive manufacturing method based on dispersion/stacking idea and droplet ejection technique. It involves machinery manufacture, electronic signals processing, graphic processing, material engineering and other disciplines. Since there were characteristics of low-cost, less time-consuming and having no special requirements for the shape of objects that were going to be printed, 3DP technique would be widely used in many areas, such as defense, medical care and production in industry. After studied effects of each of the technological parameters during printing process and powder properties on final parts, a hardware system and a kind of metal powder system were developed, and by using this system and metal powder, a metal sample was printed successfully. After measured all performance of 3DP metal samples, related data are collected.
