3D printing methods used in engineering

Abstract

3D printing as a functional Rapid Prototyping tool has been used for years, and along with the advancement of engineering technology, 3D printing technology is also developing and improving. This technology has not found representation only in the engineering industry, but across industries such as healthcare, construction, etc. In the end, I also present specific cases of the use of 3D in practice. From the most basic 3D printing with simple technology, several kinds of printing methods have evolved. From the point of view of simplicity for the novice user, the technology is FDM (Fused Deposition Modeling). With this 3D printing technology, the process of applying a thin layer of molten filament to the printing surface is used until a complete model is finally created. FDM is also characterized by the use of a wide range of materials, such as ABS, PLA, HIPS, PET-G but also wood or copper. Other methods I will describe are SLA, SLS, DOD-PolyJet. These are less available for use and acquisition by the average user, but are increasingly sought after, due to the expanded printing options. In the end, there is also an example that we processed for a company in the field of assembly.
