Our approach provides two contributions to reconstruct a restoration with a smooth join to the broken object, necessary for object functionality such as liquid containment, injury prevention, and visual aesthetic. As our first contribution, we leverage the original counterpart mesh to grow an exterior surface for the restoration piece that approaches the broken object within a small tolerance. As our second contribution, we project the exterior surface boundary onto the broken object to create a fracture surface boundary whose vertices satisfy the constraints of proximity, normal alignment, and tangency to vertices on the exterior surface boundary. Our approach prevents artifacts of volumetric Boolean subtraction, such as floating components and thin long slivers at the join, and avoids ruts at the join region introduced by Euclidean distance thresholding. We show 3D printed restoration results for 14 objects and 3D printable results for 8 objects.","PeriodicalId":404567,"journal":{"name":"Proceedings of the 3rd Annual ACM Symposium on Computational Fabrication","volume":"81 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114481769","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, existing construction materials can not be used for 3D printing as they are, and the exploration for new materials is the key to the realization of this concept. Formability and fluidity are the key factors in evaluating whether or not materials are suitable for 3D printing, including use within the field of architecture. A standardized quantitative method to evaluate construction materials is required for the comparison between materials for various projects. For example, the concrete slump test is one of the universal standards that is used to evaluate the quality and suitability for a specific construction method. In the emerging field of construction with 3D printing, however, a standardized method is yet to be established. This paper proposes an efficient method to evaluate the formability and fluidity of concrete-based materials, while only using simple instruments. The proposed method and instruments were tested by evaluating geo-polymer-based concretes, which are relatively difficult to evaluate due to its high intrinsic viscosity. By testing with these materials, we aim to show the methods ability to be applied to a wide range of materials. Notably, materials that were evaluated to be favorable under this method were confirmed to be suitable for use in 3D printing robots, being able to be used for building large structures.","PeriodicalId":404567,"journal":{"name":"Proceedings of the 3rd Annual ACM Symposium on Computational Fabrication","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114575663","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
