Abstract

The unique capabilities of additive manufacturing (AM) technologies highlight limits in commercial CAD tools. In this manuscript, after a synthetic description of the main AM technologies based on international standards classification, geometric modeling methods and data exchange file formats available in the literature are presented. Twelve geometric models have been studied to evaluate the effectiveness of the file format, noting the file dimension and the time to open and close the file. As a result, a roadmap in the development of new tools for design in AM is drawn, taking into account the new possibilities offered by AM technologies.
