1 From rapid prototyping to additive manufacturing: history, trends and current research Marco Leite March 17, 2015

2 Outline History of rapid prototyping From RP to AM Principles of layered construction New business models and applications with AM AM Current research Our research!

3 History of rapid prototyping Rapid prototyping: Models for product development Models for Architecture Educational models Toys Impossible shapes

4 History of rapid prototyping Rapid prototyping systems emerged in 1987 with the introduction of stereolithography technology, a process that solidifies layers of ultraviolet light-sensitive liquid polymer using laser technology. In subsequent years, other rapid prototyping technologies were introduced, such as: FDM, Selective Laser Sintering and Laminated Object Manufacturing.

5 History of rapid prototyping The industry s very first 3D rapid prototyping system based on FDM Technology was introduced in April, 1992, by Stratasys. The first 3D rapid prototyping systems based on PolyJet technology were introduced by Objet in April, 2000

6 From Rapid Prototyping to Additive Manufacturing Additive Manufacturing (AM) is the "process of joining materials to make objects from 3D model data, usually layer upon layer, as opposed to subtractive manufacturing methodologies.
