The popularity of moulding comes from its effectiveness, scalability and versatility in terms of employed materials. Its relevance as a fabrication process is demonstrated by the extensive literature covering different aspects related to mould design, from material flow simulation to the automation of mould geometry design. In this state-of-the-art report, we provide an extensive review of the automatic methods for the design of moulds, focusing on contributions from a geometric perspective. We classify existing mould design methods based on their computational approach and the nature of their target moulding process. We summarize the relationships between computational approaches and moulding techniques, highlighting their strengths and limitations. Finally, we discuss potential future research directions.","lang":"eng"}],"type":"journal_article","date_published":"2022-09-01T00:00:00Z","page":"435-452","article_type":"original","citation":{"mla":"Alderighi, Thomas, et al. “State of the Art in Computational Mould Design.” Computer Graphics Forum, vol. 41, no. 6, Wiley, 2022, pp. 435–52, doi:10.1111/cgf.14581.","short":"T.

Given a sequence of desired stable states and the corresponding poses of the structure, we identify the topology and geometric realization of a mechanism—consisting of bars and joints—that is able to physically reproduce the desired multistable behavior. In order to solve this problem efficiently, we build on insights from minimally rigid graph theory to identify simple but effective topologies for the mechanism. We then optimize its geometric parameters, such as joint positions and bar lengths, to obtain correct transitions between the given poses. Simultaneously, we ensure adequate stability of each pose based on an effective approximate error metric related to the elastic energy Hessian of the bars in the mechanism. As demonstrated by our results, we obtain functional multistable mechanisms of manageable complexity that can be fabricated using 3D printing. Further, we evaluated the effectiveness of our method on a large number of examples in the simulation and fabricated several physical prototypes.","lang":"eng"}],"issue":"5"},{"publication_identifier":{"issn":["1878-8750"],"eissn":["1878-8769"]},"month":"02","isi":1,"quality_controlled":"1","external_id":{"pmid":["31733380"],"isi":["000512878200104"]},"language":[{"iso":"eng"}],"doi":"10.1016/j.wneu.2019.11.038","publisher":"Elsevier","department":[{"_id":"BeBi"}],"publication_status":"published","pmid":1,"year":"2020","volume":134,"date_created":"2019-12-29T23:00:48Z","date_updated":"2023-08-17T14:14:23Z","author":[{"last_name":"Dodier","first_name":"Philippe","full_name":"Dodier, Philippe"},{"last_name":"Auzinger","first_name":"Thomas","orcid":"0000-0002-1546-3265","id":"4718F954-F248-11E8-B48F-1D18A9856A87","full_name":"Auzinger, Thomas"},{"full_name":"Mistelbauer, Gabriel","first_name":"Gabriel","last_name":"Mistelbauer"},{"first_name":"Wei Te","last_name":"Wang","full_name":"Wang, Wei Te"},{"last_name":"Ferraz-Leite","first_name":"Heber","full_name":"Ferraz-Leite, Heber"},{"full_name":"Gruber, Andreas","first_name":"Andreas","last_name":"Gruber"},{"full_name":"Marik, Wolfgang","first_name":"Wolfgang","last_name":"Marik"},{"last_name":"Winter","first_name":"Fabian","full_name":"Winter, Fabian"},{"full_name":"Fischer, Gerrit","last_name":"Fischer","first_name":"Gerrit"},{"last_name":"Frischer","first_name":"Josa M.","full_name":"Frischer, Josa M."},{"full_name":"Bavinzski, Gerhard","last_name":"Bavinzski","first_name":"Gerhard"}],"scopus_import":"1","article_processing_charge":"No","day":"01","page":"e892-e902","article_type":"original","citation":{"apa":"Dodier, P., Auzinger, T., Mistelbauer, G., Wang, W.

However, the recently presented methods have also been resource-consuming. In the present study, we have reported a cost-efficient planning workflow for extracranial-intracranial (EC-IC) revascularization combined with transdural indocyanine green videoangiography (tICG-VA). METHODS:We performed a retrospective review at a single tertiary referral center from 2011 to 2018. A novel software-derived workflow was applied for 25 of 92 bypass procedures during the study period. The precision and accuracy were assessed using tICG-VA identification of the cortical recipients and a comparison of the virtual and actual data. The data from a control group of 25 traditionally planned procedures were also matched. RESULTS:The intraoperative transfer time of the calculated coordinates averaged 0.8 minute (range, 0.4-1.9 minutes). The definitive recipients matched the targeted branches in 80%, and a neighboring branch was used in 16%. Our workflow led to a significant craniotomy size reduction in the study group compared with that in the control group (P = 0.005). tICG-VA was successfully applied in 19 cases. An average of 2 potential recipient arteries were identified transdurally, resulting in tailored durotomy and 3 craniotomy adjustments. Follow-up patency results were available for 49 bypass surgeries, comprising 54 grafts. The overall patency rate was 91% at a median follow-up period of 26 months. No significant difference was found in the patency rate between the study and control groups (P = 0.317). CONCLUSIONS:Our clinical results have validated the presented planning and surgical workflow and support the routine implementation of tICG-VA for recipient identification before durotomy.","lang":"eng"}],"intvolume":" 134","title":"Novel software-derived workflow in extracranial–intracranial bypass surgery validated by transdural indocyanine green videoangiography","status":"public","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","_id":"7220","oa_version":"None"},{"article_processing_charge":"No","day":"01","scopus_import":"1","date_published":"2020-08-01T00:00:00Z","citation":{"ama":"Dodier P, Winter F, Auzinger T, et al.

Techniques that enable this procedure to be performed easily in routine clinical practice would be useful. A cadaveric study was developed in which a new software tool was used to perform single-stage reconstructions with prefabricated implants after the resection of skull-infiltrating pathologies. A novel 3D visualization and interaction framework was developed to create 10 virtual craniotomies in five cadaveric specimens. Polyether ether ketone (PEEK) implants were manufactured according to the bone defects. The image-guided craniotomy was reconstructed with PEEK and compared to polymethyl methacrylate (PMMA). Navigational accuracy and surgical precision were assessed. The PEEK workflow resulted in up to 10-fold shorter reconstruction times than the standard technique. Surgical precision was reflected by the mean 1.1 ± 0.29 mm distance between the virtual and real craniotomy, with submillimetre precision in 50%. Assessment of the global offset between virtual and actual craniotomy revealed an average shift of 4.5 ± 3.6 mm. The results validated the ‘elective single-stage cranioplasty’ technique as a state-of-the-art virtual planning method and surgical workflow. This patient-tailored workflow could significantly reduce surgical times compared to the traditional, intraoperative acrylic moulding method and may be an option for the reconstruction of bone defects in the craniofacial region.","lang":"eng"}],"type":"journal_article","oa_version":"None","_id":"7218","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","intvolume":" 49","status":"public","title":"Single-stage bone resection and cranioplastic reconstruction: Comparison of a novel software-derived PEEK workflow with the standard reconstructive method","publication_identifier":{"issn":["0901-5027"],"eissn":["1399-0020"]},"month":"08","doi":"10.1016/j.ijom.2019.11.011","language":[{"iso":"eng"}],"external_id":{"isi":["000556819800005"],"pmid":["31866145"]},"isi":1,"quality_controlled":"1","author":[{"full_name":"Dodier, Philippe","first_name":"Philippe","last_name":"Dodier"},{"full_name":"Winter, Fabian","last_name":"Winter","first_name":"Fabian"},{"orcid":"0000-0002-1546-3265","id":"4718F954-F248-11E8-B48F-1D18A9856A87","last_name":"Auzinger","first_name":"Thomas","full_name":"Auzinger, Thomas"},{"last_name":"Mistelbauer","first_name":"Gabriel","full_name":"Mistelbauer, Gabriel"},{"first_name":"Josa M.","last_name":"Frischer","full_name":"Frischer, Josa M."},{"first_name":"Wei Te","last_name":"Wang","full_name":"Wang, Wei Te"},{"full_name":"Mallouhi, Ammar","last_name":"Mallouhi","first_name":"Ammar"},{"first_name":"Wolfgang","last_name":"Marik","full_name":"Marik, Wolfgang"},{"full_name":"Wolfsberger, Stefan","first_name":"Stefan","last_name":"Wolfsberger"},{"full_name":"Reissig, Lukas","last_name":"Reissig","first_name":"Lukas"},{"full_name":"Hammadi, Firas","last_name":"Hammadi","first_name":"Firas"},{"last_name":"Matula","first_name":"Christian","full_name":"Matula, Christian"},{"full_name":"Baumann, Arnulf","first_name":"Arnulf","last_name":"Baumann"},{"first_name":"Gerhard","last_name":"Bavinzski","full_name":"Bavinzski, Gerhard"}],"volume":49,"date_updated":"2023-08-17T14:15:22Z","date_created":"2019-12-29T23:00:47Z","pmid":1,"year":"2020","publisher":"Elsevier","department":[{"_id":"BeBi"}],"publication_status":"published"},{"publication_identifier":{"issn":["0730-0301"]},"month":"11","project":[{"call_identifier":"H2020","name":"MATERIALIZABLE: Intelligent fabrication-oriented Computational Design and Modeling","grant_number":"715767","_id":"24F9549A-B435-11E9-9278-68D0E5697425"}],"isi":1,"quality_controlled":"1","external_id":{"isi":["000498397300007"]},"oa":1,"language":[{"iso":"eng"}],"doi":"10.1145/3355089.3356576","article_number":"157","ec_funded":1,"file_date_updated":"2020-07-14T12:47:49Z","department":[{"_id":"BeBi"}],"publisher":"ACM","publication_status":"published","year":"2019","volume":38,"date_created":"2019-11-26T14:22:09Z","date_updated":"2024-03-28T23:30:47Z","related_material":{"record":[{"status":"public","relation":"dissertation_contains","id":"12897"}]},"author":[{"first_name":"Christian","last_name":"Hafner","id":"400429CC-F248-11E8-B48F-1D18A9856A87","full_name":"Hafner, Christian"},{"full_name":"Schumacher, Christian","first_name":"Christian","last_name":"Schumacher"},{"first_name":"Espen","last_name":"Knoop","full_name":"Knoop, Espen"},{"first_name":"Thomas","last_name":"Auzinger","id":"4718F954-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-1546-3265","full_name":"Auzinger, Thomas"},{"id":"49876194-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-6511-9385","first_name":"Bernd","last_name":"Bickel","full_name":"Bickel, Bernd"},{"full_name":"Bächer, Moritz","first_name":"Moritz","last_name":"Bächer"}],"scopus_import":"1","article_processing_charge":"No","has_accepted_license":"1","day":"06","article_type":"original","citation":{"mla":"Hafner, Christian, et al. “X-CAD: Optimizing CAD Models with Extended Finite Elements.” ACM Transactions on Graphics, vol. 38, no. 6, 157, ACM, 2019, doi:10.1145/3355089.3356576.","short":"C.

Our method works directly on the intersection between the model and a regular simulation grid, without the need to mesh or remesh, thus removing a bottleneck of classical shape optimization strategies. This is made possible by a novel hierarchical integration scheme that accurately integrates finite element quantities with sub-element precision. For optimization, we efficiently compute analytical shape derivatives of the entire framework, from model intersection to integration rule generation and XFEM simulation. Moreover, we describe a differentiable projection of shape parameters onto a constraint manifold spanned by user-specified shape preservation, consistency, and manufacturability constraints. We demonstrate the utility of our approach by optimizing mass distribution, strength-to-weight ratio, and inverse elastic shape design objectives directly on parameterized 3D CAD

However, the physical fabrication constraints of the molding technique commonly restrict the shape of moldable objects. For a complex shape, a decomposition of the object into moldable parts is a common strategy to address these constraints, with plastic model kits being a popular and illustrative example. However, conducting such a decomposition requires considerable expertise, and it depends on the technical aspects of the fabrication technique, as well as aesthetic considerations. We present an interactive technique to create such decompositions for two-piece molding, in which each part of the object is cast between two rigid mold pieces. Given the surface description of an object, we decompose its thin-shell equivalent into moldable parts by first performing a coarse decomposition and then utilizing an active contour model for the boundaries between individual parts. Formulated as an optimization problem, the movement of the contours is guided by an energy reflecting fabrication constraints to ensure the moldability of each part. Simultaneously, the user is provided with editing capabilities to enforce aesthetic guidelines. Our interactive interface provides control of the contour positions by allowing, for example, the alignment of part boundaries with object features. Our technique enables a novel workflow, as it empowers novice users to explore the design space, and it generates fabrication-ready two-piece molds that can be used either for casting or industrial injection molding of free-form objects."}],"issue":"4","type":"journal_article","date_published":"2018-08-04T00:00:00Z","publication":"ACM Transaction on Graphics","citation":{"chicago":"Nakashima, Kazutaka, Thomas Auzinger, Emmanuel Iarussi, Ran Zhang, Takeo Igarashi, and Bernd Bickel. “CoreCavity: Interactive Shell Decomposition for Fabrication with Two-Piece Rigid Molds.” ACM Transaction on Graphics.

Methods: We retrospectively reviewed a consecutive series of 40 patients harboring 59 aneurysms treated with 54 PEDs. Aneurysm complexity was assessed using our proposed classification. Immediate angiographic results were analyzed using previously published grading scales and our novel flow disruption scale. Results: According to our new definition, 46 (78%) aneurysms were classified as complex. Most PED interventions were performed in the paraophthalmic and cavernous internal carotid artery segments. Excellent neurologic outcome (modified Rankin Scale 0 and 1) was observed in 94% of patients. Our data showed low permanent procedure-related mortality (0%) and morbidity (3%) rates. Long-term angiographic follow-up showed complete occlusion in 81% and near-total obliteration in a further 14%. Complete obliteration after deployment of a single PED was achieved in all standard aneurysms with 1-year follow-up. Our new scale was an independent predictor of aneurysm occlusion in a multivariable analysis. All aneurysms with a high flow disruption grade showed complete occlusion at follow-up regardless of PED number or aneurysm complexity. Conclusions: Treatment with the PED should be recognized as a primary management strategy for a highly selected cohort with predominantly complex intracranial aneurysms. We further show that a priori assessment of aneurysm complexity and our new postinterventional angiographic flow disruption scale predict occlusion probability and may help to determine the adequate number of per-aneurysm devices."}],"publist_id":"7431","type":"journal_article"},{"_id":"1002","user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","ddc":["003","004"],"title":"Functionality-aware retargeting of mechanisms to 3D shapes","status":"public","intvolume":" 36","pubrep_id":"1050","file":[{"file_id":"4728","relation":"main_file","date_updated":"2018-12-12T10:09:05Z","date_created":"2018-12-12T10:09:05Z","access_level":"open_access","file_name":"IST-2018-1050-v1+1_MechRet.pdf","creator":"system","content_type":"application/pdf","file_size":25463895}],"oa_version":"Submitted Version","type":"conference","alternative_title":["ACM Transactions on Graphics"],"abstract":[{"text":" We present an interactive design system to create functional mechanical objects.

Our algorithm interactively optimizes the mechanism while the user manipulates the placement of mechanical components and the shape.

Existing indicators of interdisciplinarity are not capable of reflecting the inaccuracies introduced by incorrect and incomplete records because correct and complete bibliographic data can rarely be obtained. This is the case for the Rao–Stirling index, which cannot handle references that are not categorized into disciplinary fields. We introduce a method that addresses this problem. It extends the Rao–Stirling index to acknowledge missing data by calculating its interval of uncertainty using computational optimization. The evaluation of our method indicates that the uncertainty interval is not only useful for estimating the inaccuracy of interdisciplinarity measurements, but it also delivers slightly more accurate aggregated interdisciplinarity measurements than the Rao–Stirling index.","lang":"eng"}],"type":"journal_article","date_published":"2016-04-01T00:00:00Z","citation":{"ama":"Calatrava Moreno M, Auzinger T, Werthner H.

Our framework allows the exact evaluation of the convolution integral with a linear function defined on the polytopes. The filter is a spherically symmetric polynomial of any order, supporting approximations to refined variants such as the Mitchell-Netravali filter family. This enables high-quality rasterization of triangles and tetrahedra with linearly interpolated vertex values to regular and non-regular grids. A closed form solution of the convolution is presented and an efficient implementation on the GPU using DirectX and CUDA C is described.
