However, integrated designs hinder the ability to change and service components over time \u2013 actually increasing costs \u2013 which is instead enabled by highly modular designs. Finding the optimal trade-off between integral and modular designs in additive manufacturing is of critical importance. In this article, a product modularisation methodology is proposed for supporting such trade-offs. The methodology is based on combining function modelling with optimisation algorithms. It evaluates product design concepts with respect to product adaptability, component interface costs, manufacturing costs and cost of post-processing activities. The developed product modularisation methodology is derived from data collected through a series of workshops with industrial practitioners from three different manufacturer companies of space products. The implementation of the methodology is demonstrated in a case study featuring the redesign of a satellite antenna.<\/jats:p>","DOI":"10.1177\/1063293x19883421","type":"journal-article","created":{"date-parts":[[2019,10,29]],"date-time":"2019-10-29T06:50:18Z","timestamp":1572331818000},"page":"331-346","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":17,"title":["Modular product design for additive manufacturing of satellite components: maximising product value using genetic algorithms"],"prefix":"10.1177","volume":"27","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8886-2323","authenticated-orcid":false,"given":"Olivia","family":"Borgue","sequence":"first","affiliation":[{"name":"Department of Industrial and Materials Science, Chalmers University of Technology, Gothenburg, Sweden"}]},{"given":"Massimo","family":"Panarotto","sequence":"additional","affiliation":[{"name":"Department of Industrial and Materials Science, Chalmers University of Technology, Gothenburg, Sweden"}]},{"given":"Ola","family":"Isaksson","sequence":"additional","affiliation":[{"name":"Department of Industrial and Materials Science, Chalmers University of Technology, Gothenburg, Sweden"}]}],"member":"179","published-online":{"date-parts":[[2019,10,29]]},"reference":[{"key":"bibr1-1063293X19883421","doi-asserted-by":"publisher","DOI":"10.1145\/291469.291479"},{"key":"bibr2-1063293X19883421","first-page":"932","volume-title":"Proceedings of twenty third annual international solid freeform fabrication symposium: an additive manufacturing conference","volume":"13","author":"Baumers M","year":"2012"},{"key":"bibr3-1063293X19883421","unstructured":"Brown O, Eremenko P (2006) Fractionated space architectures: a vision for responsive space.
