There are several types of 3D printing methods that are often used by people, however, maybe you have never heard of these methods. One of them is Electronic Beam Melting (EBM). The difference with SLM, the SLM uses high power laser light as a power source, while EBM uses an electron beam instead. That is the difference between these two methods. The material used in EBM is a metal powder that melts and forms a 3D layer. Contrary to SLS, EBM is used to completely melt metal powders. This process is usually carried out under high temperatures up to 1000 ° C. Compared to SLM, the EBM process is rather slow and expensive. In addition, limited material is also an obstacle. So, this method is not very popular although it is still used in several manufacturing processes.

In addition to EBM, Selective laser melting (SLM) is a technique that also uses 3D CAD data as a source and forms 3D objects using high-fused laser power. SLM is considered a subcategory of selective laser sintering (SLS), but this is not so true because the SLM process completely melts metal materials into solid 3D-dimensional parts, unlike Selective Laser Sintering (SLS). This measurement method is widely applied to parts of geometry and complex structures with surfaces and channels.
In addition to SLM, Fused Deposition Modeling (FDM) technology is currently widespread in various industries, such as Hyundai and BMW car companies or food companies such as Nestle and Dial. FDM is used for new product development, concept models and prototypes. Even in manufacturing development, this technology is considered easy to use and environmentally friendly. Using this printing method, it is possible to construct objects with complex geometries and cavities.
Well. that’s the techniques – techniques commonly used in 3D printing, the various techniques are quite complex. Therefore, it takes a person who is truly adept at operating it, in order to obtain good and quality results.
