In fact, 3D printing technology has not been developed for a long time in China. 3D printing is also known as additive manufacturing. Based on the data of 3D model, it is a process to make materials into objects. You should know little about the 3D printing powder of these two metals. At least in China, the research on the spherical powder of refractory metals in the field of 3D printing powder of metals is relatively rare.
Both the 3D printing tantalum and the 3D printing tungsten belong to the spherical powder of refractory metal. In 2018 technology has been completed the test of the 3D printing tungsten printing process and achieved good results in the 3D printing technology. Although both 3d-printed tantalum and 3d-printed tungsten are metal 3d-printed powders, their application fields are completely different. 3d-printed tantalum is mainly used in the medical industry. As early as 2017, there was a case in China that 3D printed tantalum was used in the medical field. Have learned, combining medical technology for patients with customized 3 d printing tantalum metal block good joint degrees and the surface roughness, perfect filled large bone defect, and ensures that the bone defect after tantalum metal block the initial stability of the implant, the rough surface of the porous metal and trabecular bone design can make autologous bone ingrowth fast metal pore, thereby gaining, long-term stability of the prosthesis and autologous bone surgery operation process greatly simplified, and reduce the surgical complications.
Tungsten in 3d-printed tungsten is a typical rare metal with high tensile strength. 3d-printed tungsten is widely used in electronics, aerospace, casting and other industries, so tungsten can be used in 3D printing to produce complex structural parts with excellent performance. At present, 3D printed tungsten has not been well popularized in 3D printing technology, and it is difficult to be applied in large and complex structural parts. However, considering the excellent properties of tungsten metal, with the continuous progress and improvement of technology, it will have a broader prospect in the field of medical and aerospace.
