THEORETICAL ANALYSIS AND PRACTICAL CASE STUDIES OF SLA, POLYJET AND FDM MANUFACTURING TECHNIQUES

Among the most advanced technologies developed in recent years, Additive Manufacturing (AM) is one that meets the requirements of the Fourth Industrial Revolution. In this paper, we present some AM methods such as stereolithography (SLA), polyjet and fused deposition modeling (FDM).       The AM technologies analyzed use raw material in liquid form and filament. The study is focused on three important aspects like the processing principle, the material used by each technology and the latest practical examples developed. The products exposed are from various domains such us medicine, automotive, aerospace and industry. Furthermore, we detailed the main manufacturers of AM systems, their equipments and the cost range.
