However, this freedom needs to be utilized by appropriate CAx tools. In this paper, we present a novel slicing method, enabling the automatic generation of topology-optimized Laminated Layer Manufacturing (LLM) parts. With this method a part of arbitrary shape can be automatically sliced and equipped with a uniform virtual grid that is suitable for manufacturing. The optimal density distribution is then mapped onto the individual slices and locally approximated through the introduction of variably shaped cavities. By using 3D modeling techniques all LLM sheets are modeled parametrically and assembled automatically. To verify the functionality of the presented method, it is applied to two practical parts and compared with a conventional topology optimization method.", "issn" : "22128271", "doi" : "10.1016/j.procir.2020.04.048", "bibtexKey": "Helfesrieder.2020" } , { "type" : "Publication", "id" : "https://puma.ub.uni-stuttgart.de/bibtex/29d704fdcc56ba0b44dff76b856fee79f/itke", "tags" : [ "overview","approach","bending-active","knippers","erazo","structure","2017","itke","from:petraheim","comarative","tensile","computational","form-finding","suzuki","architecture","slabbinck","generative" ], "intraHash" : "9d704fdcc56ba0b44dff76b856fee79f", "interHash" : "cef103fe0e76bba353a3b7dc1cd0a652", "label" : "A comparative overview of generative approaches for computational form-finding of bending-active tensile structures", "user" : "itke", "description" : "", "date" : "2020-06-02 12:06:24", "changeDate" : "2020-06-02 10:06:24", "count" : 3, "pub-type": "inproceedings", "booktitle": "Proceedings of the IASS Annual Symposium 2017","address":"Hamburg, Germany", "year": "2017", "url": "", "author": [ "Seiichi Suzuki Erazo","Evy Laura Maurice Slabbinck","Jan Knippers" ], "authors": [ {"first" : "Seiichi", "last" : "Suzuki Erazo"}, {"first" : "Evy Laura Maurice", "last" : "Slabbinck"}, {"first" : "Jan", "last" : "Knippers"} ], "language" : "eng", "bibtexKey": "suzukierazo2017comparative" } , { "type" : "Publication", "id" : "https://puma.ub.uni-stuttgart.de/bibtex/203435eab281e09370cc90b1d6ac79c22/itke", "tags" : [ "2017","approach","architecture","bending-active","comarative","computational","erazo","form-finding","from:petraheim","generative","itke","knippers","overview","slabbinck","structure","suzuki","tensile" ], "intraHash" : "03435eab281e09370cc90b1d6ac79c22", "interHash" : "cef103fe0e76bba353a3b7dc1cd0a652", "label" : "A comparative overview of generative approaches for computational form-finding of bending-active tensile structures", "user" : "itke", "description" : "", "date" : "2020-05-22 14:23:02", "changeDate" : "2020-05-25 11:25:15", "count" : 3, "pub-type": "inproceedings", "booktitle": "Proceedings of the IASS Annual Symposium 2017","address":"Hamburg, Germany", "year": "2017", "url": "", "author": [ "Seiichi Suzuki Erazo","Evy L.

They feature hardly any modularity and do not allow reconfiguration in a significant process change. One possibility to adapt machines is to produce them from plastic or composite materials through generative methods. This printed machine is a reconfigurable, monolithic module, in which drives are integrated. By a cooperative motion generation, larger workspaces can be realized while the installation spaces decrease. This gives the possibility to use alternative drive technologies, for example piezo-drives. Based on these methods, two small generatively produced machine tools are designed, using two different drive principles. The first machine tool is equipped with ball screw drives, which are cost efficient and space saving. The second machine tool uses piezo-actuators, which are very dynamic in motion generation. Further has to be examined, which tolerances and rigidities are needed at critical points and whether a generative or a conventional production is feasible.", "__markedentry" : "[xtl:6]", "bibtexKey": "BatkeWurstLechlerEtAl2014" } , { "type" : "Publication", "id" : "https://puma.ub.uni-stuttgart.de/bibtex/27ef209c28123377d8346991bfa1cfd4f/isw-bibliothek", "tags" : [ "Fertigungsverfahren","ISW","Werkzeugmaschine,","generative" ], "intraHash" : "7ef209c28123377d8346991bfa1cfd4f", "interHash" : "f3e45fdf217b5f4c8e887d122e2b479b", "label" : "Die gedruckte Werkzeugmaschine: Die gedruckte Werkzeugmaschine", "user" : "isw-bibliothek", "description" : "", "date" : "2016-03-03 09:53:12", "changeDate" : "2016-03-03 09:18:35", "count" : 1, "pub-type": "misc", "year": "2013", "url": "", "author": [ "C.
