3D printing system for manufacturing human skeletons

The invention provides a 3D printing system for manufacturing human skeletons. The 3D printing system comprises a laser device, a galvanometer connected to the laser device through an optical fiber, a heater for preheating, a worktable device with a forming area and a powder supply device used for supplying powder to the forming area, wherein the heater is arranged above the worktable device, and the powder supply device is arranged on one side of the worktable device. According to the 3D printing system for manufacturing the human skeletons, the SLM forming technology is adopted, and therefore the efficiency of manufacturing the human skeletons is improved, the steps are simplified, and the production cost is greatly lowered.
