In real life, from food to cars to parts, 3D printing technology has indeed been continuously developed and realized. So, is 3D printing technology printing fasteners feasible?
I do not know if you have not seen a movie called "Zodiac". In addition to Jackie Chan's signature action movie, it impressed me more than 3D printing technology. In the film, Jackie Chan uses a glove with a sensor to scan the head of the beast, store the data in a computer, then perform 3D modeling, and finally print a perfect replica of the 3D. The
This plot looks full of science fiction, but in real life, from food to cars to parts, 3D printing technology has indeed been continuously developed and realized, and is likely to subvert the product manufacturing industry. The
What is 3D printing?
As the name suggests, 3D printing is to print three-dimensional objects. It is a technology based on digital model files, using powdered metals or plastics and other adhesive materials to build objects by layer-by-layer printing. The
It can extract useful materials from metal powders, sand and other materials. It not only wastes almost no material, but also improves the material. It can generate most of the complicated parts without the use of molds and tools, greatly improving Productivity and manufacturing flexibility. The
What is metal 3D printing?
Metal 3D printing is a technology of digital thermal processing. At present, 3D printing technologies for metal preparation include: selective laser melting/sintering (SLM/SLS), electron beam selective melting (EBSM), laser near-net forming (LENS), etc. . Compared with the traditional process, metal 3D printing has direct molding, no mold, can achieve personalized design and production of complex structures, high efficiency, low consumption, low cost and other advantages. But because it is a digital thermal processing, deformation can not be eliminated, the amount of deformation needs to be controlled from the process and experience, and finally through the post-processing processing of CNC machine tools and other technologies. The
At present, metal powders used in metal 3D printers at home and abroad generally include: tool steels, martensitic steels, stainless steels, pure titanium and titanium alloys, aluminum alloys, nickel-based alloys, copper-based alloys, and cobalt-chromium alloys.
