3D printing or additive manufacturing is the process of making 3D object from digital file. Many different objects (from chocolate to working gun) can be created with 3D printing, and it has been used within many industries such as automotive industry, healthcare industry, aerospace industry, and many more. 3D printing was first known as Rapid Prototyping (RP) in the late 1980s, and it was used in industry to create sample product faster and cheaper. The first patent of RP was developed by Dr. Kodama, in 1980, but the full patent specification was not filed before the one year deadline after the application. In 1986, the origin of 3D printing belong to Charles Hull, who first invented his stereolithography apparatus (SLA) in 1983. Hull went …show more content…
The main process of the EBM is very similar to SLM, and the different is SLM uses high-power laser beam source, while EBM uses an electron beam to power the bed fusion technique. To print an object, a computer controls electron beam in high vacuum to melt the metal powder and form 3D part layer by layer, and the temperature which is used by this process is up to 1000 oC. Nevertheless, the materials for this method are pure Titanium, Inconel 718 and Inconel 625. Due to high cost material, this method is not very popular, but it is still used in some industry such as …show more content…
As a result, 3D printing will be the future of manufacturing products. When 3D printing is well developed and when its price is affordable, we will be able to build objects of our dream without any help of other expensive machines. The fast emerging of 3D printing will definitely be the main device each person has to have in the near future. Moreover, it will bring over the revolution in health care industry by creating living organs, and in education industry by bringing out the creativity of each student. The reason I choose this topic because I cannot wait to see the future of 3D printing, and I want build my own objects with the ideas I have been dreaming of for
