Visual and geometrical properties are a major criterion for characterizing the resulting component quality. The aim of this study was to investigate the influences on visual and geometrical properties of APF components depending on process parameters. Initially the focus was on the analysis of the shrinkage behavior of ABS-M30 (Stratasys). On the basis of the results and an existing procedure by the machine manufacturer, an optimized procedure for determining the scaling factors was developed to counteract the shrinkage. With this procedure a higher dimensional accuracy of the components can be achieved. In addition, it was investigated whether an adaption of the form factor based on a mathematical model depending on the component geometry makes sense. The results were transferred into manufacturing guidelines, which allow the user of the APF-technology to optimize process parameters more efficiently.}}, author = {{Moritzer, Elmar and Hecker, Felix and Elsner, Christian Lennart and Hirsch, André}}, booktitle = {{Proceedings: 2021 Annual International Solid Freeform Fabrication Symposium (SFF Symp 2021)}}, editor = {{Bourell, David}}, location = {{Austin, Texas, USA}}, pages = {{467--474}}, title = {{{Investigations for the Optimization of Visual and Geometrical Properties of Arburg Plastic Freeforming Components}}}, doi = {{10.26153/tsw/17567}}, year = {{2021}}, } @inproceedings{24099, abstract = {{The additive manufacturing process Fused Deposition Modeling (FDM) is established in the industry for many years. A new, similar process to FDM is the Arburg Plastic Freeforming (APF). The main differences between both processes are the form of the starting material (FDM: Filaments, APF: Conventional granulate) and the material deposition during the layer formation (FDM: Melt strand, APF: fine molten droplets). Since the two processes can be used in similar applications, the aim of this study is to compare both processes in a holistic way. Furthermore, the advantages and disadvantages of the processes are to be highlighted. The systematic comparison between a Stratasys 400mc and the Freeformer 200-3X is divided into the areas of component properties, design limitations and economic efficiency. The material ABS-M30 (Stratasys) is used in both processes. The results show comparable component properties regarding mechanical and optical properties but also differences in design limitations and cost efficiency. }}, author = {{Moritzer, Elmar and Hecker, Felix and Driediger, Christine and Hirsch, André}}, booktitle = {{Proceedings: 2021 Annual International Solid Freeform Fabrication Symposium (SFF Symp 2021)}}, editor = {{Bourell, David}}, location = {{Austin, Texas, USA}}, pages = {{575--584}}, title = {{{Comparison of Component Properties and Economic Efficiency of the Arburg Plastic Freeforming and Fused Deposition Modeling}}}, doi = {{10.26153/tsw/17577}}, year = {{2021}}, } @inproceedings{24096, abstract = {{The Arburg Plastic Freeforming (APF) is an additive manufacturing process with which three-dimensional, thermoplastic components can be produced layer by layer. One disadvantage of the APF is the long residence time of the molten material in the plasticizing unit compared to conventional injection moulding. The dosing volume is emptied very slowly due to only discharging fine plastic droplets. As a result, long residence times can be expected, which can lead to thermal degradation of the material. The aim of this study was to develop a model for calculating the residence time of the material in the APF. The residence time of the material in the thermally critical dosing volume is predicted using software developed in-house. The accuracy of the model could be verified by experimental investigations. Finally, the thermal degradation of the material was investigated by analyzing the correlation to the mechanical properties of tensile strength specimens. }}, author = {{Moritzer, Elmar and Hecker, Felix and Hirsch, André}}, booktitle = {{Proceedings: 2021 Annual International Solid Freeform Fabrication Symposium (SFF Symp 2021)}}, editor = {{Bourell, David}}, location = {{Austin, Texas, USA}}, pages = {{1268--1275}}, title = {{{Investigation and Modeling of the Residence Time Dependent Material Degradation in the Arburg Plastic Freeforming}}}, doi = {{10.26153/tsw/17643}}, year = {{2021}}, } @article{50363, author = {{Kückmann, Marie-Ann and Kundisch, Heike}}, journal = {{Didaktisierung des Digitalen: Zur Entwicklung berufs- und wirtschaftspädagogischer Studiengänge}}, publisher = {{bwp@ Berufs- und Wirtschaftspädagogik - online}}, title = {{{Denken mit dem Stift?! – Digitale Visualisierungsprozesse als Zugang zu komplexen wirtschafts- und berufspädagogischen Themenfeldern.}}}, year = {{2021}}, } @inproceedings{26812, author = {{Leffrang, Dirk and Müller, Oliver}}, booktitle = {{IEEE Workshop on TRust and EXpertise in Visual Analytics}}, title = {{{Should I Follow this Model?

Hereby, different media such as motor oil or Glysantin based coolant were tested with different temperatures and immersion times of up to 26 weeks.
