1 Optimization of Additive Manufacturing Processes Focused on 3D Printing Razvan Udroiu and Anisor Nedelcu “Transilvania” University of Brasov Romania 1. Introduction Under the umbrella of Rapid-X (Udroiu Ivan, 2008) there are some specific terms such as: Rapid Product Development (RPD), Rapid Technology, Rapid Nanotechnology, Rapid Prototyping (RP), Rapid Tooling (RT) and Rapid Manufacturing (RM). Additive manufacturing (AM) is an important component of the rapid product development process. Additive manufacturing technologies (AMT) represents a group of technologies used for building physical models, prototypes, tooling components and finished parts, all from three dimensional (3D) computer aided design (CAD) data or data from 3D scanning system. AMT involves automated fabrication of physically complex shapes directly from 3D CAD, using a layer-by-layer deposition principle. Based on AM principles, RP produces parts with limited functionality (prototypes and test parts), RM built end products and RT manufacture tools, jigs or moulds. Todays additive technologies offer advantages in many applications compared to classical subtractive fabrication methods like as milling, turning etc. Thus, parts can be formed with any geometric complexity or intricacy without the need for elaborate machine setup or final assembly. Also, AMT can lower manufacturing time of new products with 8-10 times in comparison with the conventional te
