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.}},

  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.

  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.

Zwischen Online-Meetings, Breakout Rooms, Etherpads und Open Source Documents ist eine (a)synchrone Lehre sowohl Experimentierfeld für die Gestaltung von digitalen Lehrformaten als auch Hoffnungsträger, Kontakte dort herzustellen, wo sie für die Aufrechterhaltung von Bildungschancen unabdingbar sind, aber eben nur im virtuellen Raum gepflegt werden dürfen. Obwohl konzeptionelle Überlegungen und Strategien zur Förderung von Medienkompetenz bereits seit vielen Jahren entwickelt und publiziert werden, hat die Corona-Situation gezeigt, dass viele Überlegungen zu kurz greifen oder schlichtweg in der Praxis nicht realisierbar sind.
Der vorliegende Sammelband möchte sich vor allem jenen didaktischen Formaten zuwenden, die in der berufs- und wirtschaftspädagogischen Hochschullehre mit einem Fokus auf den virtuellen Raum entwickelt worden sind und sich während der vergangenen Online-Semester als praktikabel bewährt haben. Das Ziel ist es die verschiedenen Angebote zu systematisieren und aus einer Lehrperspektive zu reflektieren. }},

Therefore, the laser sintering technology is predestinated to manufacture these components as it offers a very high degree of design freedom and good mechanical properties.
For industrial applications the long-term properties of the SLS material in contact with liquid media are important and were therefore investigated for PA12, PP and PA613. Hereby, different media such as motor oil or Glysantin based coolant were tested with different temperatures and immersion times of up to 26 weeks. The mechanical properties were tested after immersion and compared to injection molded samples. Furthermore, laser sintering design guidelines for media-carrying components were developed. These guidelines for instance include the minimum wall thickness to ensure media tightness and the removal of powder from channels with a high length to diameter ratio.}},
