摘要：

Constructing a boundary representation for an AM part is challenging due to the large number of CSG operations that need to be performed. To tackle the problem, we begin with a review of different numeric representations and their suitability for solving geometric problems. We then review the state of the art in explicit boundary representations, exploring why they are unsuitable for generating AM part models. Finally, we describe a hybrid implicit-explicit boundary representation which addresses the scalability and precision needs of AM part model generation. This merits of this approach are illustrated using several case studies. © 2019 CAD Solutions, LLC,.
