Design/methodology/approach – First, a process-independent method for the development of Design Rules was worked out. Therefore, geometrical standard elements and attributes that characterize the elements’ shapes have been defined. Next, the standard elements have been manufactured with different attribute values with Laser Sintering, Laser Melting and Fused Deposition Modeling, and their geometrical quality was examined. From the results, Design Rules for additive manufacturing were derived and summarized in a catalogue. Findings – Due to the process independent method, Design Rules were developed that apply for the different considered additive manufacturing technologies equally. These Design Rules are completely function-independent and easily transferable to individual part designs. Research limitations/implications – The developed Design Rules can only apply for the considered boundary conditions. To extend the Design Rules’ validity, their applicability should be proven for other boundary conditions. Practical implications – The developed Design Rules practically support the design of technical parts. Additionally they can be used for training and teaching in the field of “design for additive manufacturing”. Originality/value – The developed Design Rules constitute a first step toward general Design Rules for Additive Manufacturing. Thus, they might form a suitable basis for further scientific approaches, and the Design Rules can be used to set up teaching documentations for lessons and seminars.}}, author = {{dell'Aere, Guido and Zimmer, Detmar}}, isbn = {{1355-2546}}, journal = {{Rapid Prototyping Journal}}, number = {{6}}, pages = {{662--670}}, publisher = {{Emerald Group Publishing Limited}}, title = {{{On design for Additive Manufacturing - evaluating geometrical limitations}}}, doi = {{10.1108/RPJ-06-2013-0060}}, volume = {{21}}, year = {{2015}}, } @inproceedings{22395, author = {{Lieneke, Tobias and Adam, Guido and Leuders, Stefan and Knoop, Frederick and Josupeit, Stefan and Delfs, Patrick and Funke, Nils and Zimmer, Detmar}}, booktitle = {{Proceedings of the Rapid Tech 2015}}, title = {{{Entwicklung einer Methode zur systematischen Erarbeitung von Maßtoleranzen für additive Fertigungsverfahren}}}, year = {{2015}}, } @inproceedings{22396, abstract = {{Additive manufacturing offers many technical and economical benefits.

The first aim is the determination of dimensional tolerances that can be stated if additive manufacturing is used under normal workshop conditions. Within the second aim, relevant process parameters and manufacturing influences will be optimized in order to reduce dimensional deviations. To achieve both aims a method was developed first. This method identifies relevant influential factors on the geometrical accuracy for the processes Fused Deposition Modeling (FDM), Laser Sintering (LS) and Laser Melting (LM).

Therefore, based on the visual sketching model of problem solving, we propose an extension of CFT and thereby demonstrate that cognitive fit can promote problem solving performance also for creative problems. In doing so, we extend the boundary of CFT and add to creativity research a previously unknown cognitive mechanism for promoting creative performance: cognitive fit. Moreover, we contribute to general problem solving research by bridging the gap between problem solving in creativity and information systems research.}}, author = {{John, Thomas and Kundisch, Dennis}}, booktitle = {{Proceedings of the 36th International Conference on Information Systems (ICIS), Fort Worth, USA}}, location = {{Fort Worth, USA}}, title = {{{Why Fit Leads to Surprise: An Extension of Cognitive Fit Theory to Creative Problems}}}, year = {{2015}}, } @inproceedings{23055, author = {{Abrishamchian, Farisoroosh and Oestersötebier, Felix and Trächtler, Ansgar}}, booktitle = {{Proceedings of the ASME 2015 International Mechanical Engineering Congress & Exposition}}, publisher = {{ASME}}, title = {{{Feature Model Approach For Managing Variability of Dynamic Behavior Models in Mechatronic Systems}}}, year = {{2015}}, } @inproceedings{23056, author = {{Bertelsmeier, Fabian and Trächtler, Ansgar}}, booktitle = {{20th IEEE International Conference on Emerging Technologies and Factory Automation}}, title = {{{Decentralized Controller Reconfiguration Strategies for Hybrid System Dynamics based on Product-Intelligence}}}, year = {{2015}}, } @inproceedings{23057, author = {{Abdelgawad, Kareem and Hassan, Bassem and Kohlstedt, Andreas and Stöcklein, Jörg and Berssenbrügge, Jan and Grafe, Michael and Gausemeier, Sandra and Jäker, Karl-Peter and Trächtler, Ansgar}}, booktitle = {{New Developments in Driving Simulation Design and Experiments}}, publisher = {{Driving Simulation Conference}}, title = {{{Flexible Operation Workflow of a Driving Simulation Center for ADAS Development}}}, year = {{2015}}, } @inproceedings{23058, author = {{Hassan, Bassem and Stöcklein, Jörg and Berssenbrügge, Jan}}, booktitle = {{Virtual, Augmented and Mixed Reality VAMR 2015 Held as Part of HCI International 2015}}, editor = {{Shumaker, Randall and Lackey, Stephanie}}, pages = {{457 -- 469}}, publisher = {{Springer International Publishing Switzerland}}, title = {{{ARTiST - An Augmented Reality Testbed for Intelligent Technical Systems}}}, year = {{2015}}, } @inproceedings{23059, author = {{Berssenbrügge, Jan and Trächtler, Ansgar and Schmidt, Christoph}}, booktitle = {{Proceedings of the ASME 2015 International Design Engineering Technical Conferences & Computers and Information in Engineering Conference}}, title = {{{Visualization of Headlight Illumination for the Virtual Prototyping of Light-Based Driver Assistance Systems}}}, year = {{2015}}, } @article{23060, author = {{Krüger, Martin and Trächtler, Ansgar}}, journal = {{at-Automatisierungstechnik}}, number = {{8}}, pages = {{633 -- 645}}, title = {{{Parametrische Modellordnungsreduktion für hierarchische selbstoptimierende Systeme}}}, volume = {{63}}, year = {{2015}}, } @inproceedings{23062, author = {{Bertelsmeier, Fabian and Vathauer, Marc and Henke, Christian and Vathauer, Karl-Ernst and Trächtler, Ansgar}}, booktitle = {{Automation 2015}}, publisher = {{VDI-Verlag}}, title = {{{Produkt- und lastabhängiges dezentrales Motormanagement für die Fördertechnik: Anforderungen, Design und Applikation }}}, year = {{2015}}, } @inproceedings{23063, author = {{Pai, Arathi and Niendorf, Thomas and Krooß, Philipp and Koke, Isabel and Trächtler, Ansgar and Schaper, Mirko}}, booktitle = {{7th ECCOMAS Thematic Conference on Smart Structures and Materials - SMART}}, title = {{{Modelling the Constitutive Behaviour of Martensite and Austenite in Shape Memory Alloys Using Closed-Form Analytical Continuous Equations}}}, year = {{2015}}, } @article{23064, author = {{Damerow, Ulf-Hendrik and Borsig, Michael and Tabakajew, Dmitri and Schaermann, Waldemar and Hesse, Marc and Homberg, Werner and Trächtler, Ansgar and Jungeblut, Thorsten}}, journal = {{wt Werkstattstechnik online}}, pages = {{427--432}}, title = {{{Intelligente Biegeverfahren}}}, volume = {{6-2015}}, year = {{2015}}, } @inproceedings{23065, author = {{Abdelgawad, Kareem and Hassan, Bassem and Berssenbrügge, Jan and Stöcklein, Jörg and Grafe, Michael}}, booktitle = {{International Journal On Advances in Software}}, pages = {{247 -- 261}}, publisher = {{IARIA}}, title = {{{A Modular Architecture of an Interactive Simulation and Training Environment for Advanced Driver Assistance Systems}}}, volume = {{8}}, year = {{2015}}, } @article{23066, author = {{Shareef, Zeeshan and Just, Viktor and Teichrieb, Heinrich and Trächtler, Ansgar}}, journal = {{Robotica}}, pages = {{1--17}}, title = {{{Design and Control of Cooperative Ball Juggling Delta Robots without Visual Guidance}}}, year = {{2015}}, } @phdthesis{23067, author = {{Shareef, Zeeshan}}, publisher = {{Verlagsschriftenreihe des Heinz Nixdorf Instituts, Paderborn}}, title = {{{Path Planning and Trajectory Optimization of Delta Parallel Robot}}}, volume = {{345}}, year = {{2015}}, } @inproceedings{23068, author = {{Jähn, Claudius and Fischer, Matthias and Gerges, Maria and Berssenbrügge, Jan}}, booktitle = {{12.

We consider both pure equilibria and their refinement of payoff-dominant equilibria [34], where every player is no worse-off than in any other pure equilibrium. We present both structural and complexity results:We consider mutual weighted boolean formula games (MWBFG), a subclass of WBFG making a natural mutuality assumption on the formulas of players. We present a very simple exact potential for MWBFG. We establish a polynomial monomorphism from certain classes of weighted congestion games to subclasses of WBFG and MWBFG, respectively, indicating their rich structure.We present a collection of complexity results about decision (and search) problems for both pure and payoff-dominant equilibria in WBFG. The precise complexities depend crucially on five parameters: (i) the number of players; (ii) the number of variables per player; (iii) the number of formulas per player; (iv) the weights in the payoff functions (whether identical or not), and (v) the syntax of the formulas.

A methodology for a part selection process is presented, and the different criteria are developed. An approach for a redesign of the selected parts, including the gathering of requirements, is given based on different sample parts. A variation of criteria to include measures for product piracy is highlighted. Findings – The methodology has proven applicability in several research and industry projects in aerospace applications. Independent part selections from experts analyzed within a project of the European Space Agency had a 90 per cent overlap with the results. It allows companies with only basic AM knowledge to start a part screening for applicable AM candidates in their own company with a reasonable effort.

Here AM is often mentioned as a driver for product piracy as it allows to produce and to copy objects with any geometries. Imitators need a lot of information to copy an object accurately. As reverse engineering has been identified as the most important information source for product imitators, AM can also help to reduce the threat of product piracy when correctly applied in the product development. Due to the layer wise production process that allows the manufacturing of very complex shapes and geometries, the reverse-engineering process can be complicated by far. By this, quite contrary to the public opinion, AM can increase the needed effort of imitators and strongly reduce the economic efficiency of product piracy.

First the optimization algorithms are not targeted to the opportunities and restrictions of AM –represented by design rules – like the design of support structures. Secondly, the CAD software is not adjusted to AM in particular. Creating freeform shaped surfaces based on the optimization results is significantly less convenient than building defined blocks or turning parts following the needs of conventional machining.
