Density Test Results (The density test results of 9 blocks with size of 13 * 13 * 10 mm printed on the HBD-200 metal 3D printer are shown in the following table.) Ite m Cross Section of Internal Pores (Select No. 1 test block with the highest density for polishing, and its internal polishing section is as shown in the figures below.) Tungsten has proven to be a valuable 3D printing material, and many experts are interested in its heat resistance, especially in a vacuum and under high-voltage working environment. Many researchers have determined that laser powder bed fusion (LPBF/SLM metal 3D printing)...
