Abstract
The first part of the talk addressed Additive Manufacturing (AM) from the perspective of manufacturing. Differences between AM, subtractive manufacturing and formative manufacturing were explained. The evolution of AM was outlined, fundamentals of AM explained including the formal definition of AM by ISO/ASTM 52900. A short description of the seven fundamentally different AM process categories provided. In the second part of the talk the digital perspective of AM was in focus exemplified by the EC H2020 R&I Action CAxMan – Computer Aided Technologies for Additive Manufacturing. In CAxMan a 3-variate isogeometric approach for simulation based design targeting AM is addressed. CAxMan has a strong focus on the challenges of interoperability of design, simulation, process planning and actual manufacturing for AM, and development of suitable standards supporting AM.
