(editor) Papadopoulos, V. (editor) Stefanou, G. (editor) Plevris, V. (editor) Date 2016 Abstract Advances in additive manufacturing (AM) allow economical production of components with unprecedented geometric complexity. This offers exciting opportunities for innovative designs, and particularly topology optimization has been identified as a key technique to fully exploit the capabilities of AM. However, also AM involves manufacturing restrictions, such as limitations on the inclination of overhanging parts. To deal with this problem, either sacrificial supporting structures can be added during the process, or only self-supporting designs can be considered. Both approaches have disadvantages, as support structures add material and post-processing costs, while demanding exclusively self-supporting designs may impose strong restrictions on achievable performance. With current methods, designers are limited to a choice between these two extremes. To open up a wider range of designs, this paper presents and demonstrates a topology optimization formulation that allows the designer to find trade-off solutions between design performance and support structure costs, considering both printing and removal costs Subject Topology optimizationadditive manufacturingoverhang anglesupport structuresself-supporting designsmanufacturing restrictions To reference this document use: http://resolver.tudelft.nl/uuid:c0d2658b-f36f-4d77-884e-f9392c115e62 Publisher National Technical University of Athens (NTUA), Greece ISBN 978-618-82844-0-1 Source Proceedings of the 7th European Congress on Computational Methods in Applied Sciences and Engineering: ECCOMAS Congress 2016 Event 7th European Congress on Computational Methods in Applied Sciences and Engineering, 2016-06-05 → 2016-06-10, Crete, Greece Part of collection Institutional Repository Document type conference paper Rights © 2016 Matthijs Langelaar Files PDF Langelaar_eccomas_2016_vol_2.pdf 3.96 MB Close viewer /islandora/object/uuid:c0d2658b-f36f-4d77-884e-f9392c115e62/datastream/OBJ/view
