[{"abstract":[{"text":"New technologies and materials carry significant potential for sustainable production and use of products. As an example, Additive Manufacturing technologies and materials promise lightweight design and energy efficient use of parts. Exhausting the full potential requires: a) consideration of uncertainties with respect to future capabilities, and b) upgradeable design guidelines to cover advancements consistently. The proposed approach merges concepts of Design-for-X with foresight algorithms of Scenario-Technique to derive actionable knowledge. It is validated by an application in the field of Additive Manufacturing, namely Metal Fused Deposition Modelling. Engineers benefit from the intuitive access to heterogeneous types of sustainability related information.","lang":"eng"}],"user_id":"405","title":"Handling of uncertainties in the design of sustainable Additive Manufacturing products by merging Design-for-X and Scenario-Technique","publication":"Procedia CIRP ICME","department":[{"_id":"152"},{"_id":"741"}],"keyword":["Design-for-X","Scenario-Technique","sustainability","uncertainty","Life-Cycle Engineering","Additive Manufacturing","Circular Economy"],"publisher":"Elsevier","author":[{"id":"47565","last_name":"Gräßler","orcid":"0000-0001-5765-971X","full_name":"Gräßler, Iris","first_name":"Iris"},{"last_name":"Mozgova","id":"95903","first_name":"Iryna","full_name":"Mozgova, Iryna"},{"last_name":"Pottebaum","id":"405","first_name":"Jens","full_name":"Pottebaum, Jens","orcid":"http://orcid.org/0000-0001-8778-2989"},{"full_name":"Ott, Manuel","first_name":"Manuel","id":"44204","last_name":"Ott"},{"first_name":"Philipp","full_name":"Jung, Philipp","last_name":"Jung"},{"full_name":"Hesse, Philipp","first_name":"Philipp","id":"60633","last_name":"Hesse"}],"quality_controlled":"1","date_created":"2023-08-08T07:42:04Z","status":"public","editor":[{"full_name":"Teti, Roberto","first_name":"Roberto","last_name":"Teti"}],"conference":{"end_date":"2023-07-14","location":"Gulf of Naples","name":"17th CIRP Conference on Intelligent Computation in Manufacturing Engineering","start_date":"2023-07-11"},"_id":"46451","date_updated":"2023-08-23T13:58:13Z","language":[{"iso":"eng"}],"citation":{"bibtex":"@inproceedings{Gräßler_Mozgova_Pottebaum_Ott_Jung_Hesse_2023, title={Handling of uncertainties in the design of sustainable Additive Manufacturing products by merging Design-for-X and Scenario-Technique}, booktitle={Procedia CIRP ICME}, publisher={Elsevier}, author={Gräßler, Iris and Mozgova, Iryna and Pottebaum, Jens and Ott, Manuel and Jung, Philipp and Hesse, Philipp}, editor={Teti, Roberto}, year={2023} }","mla":"Gräßler, Iris, et al. “Handling of Uncertainties in the Design of Sustainable Additive Manufacturing Products by Merging Design-for-X and Scenario-Technique.” Procedia CIRP ICME, edited by Roberto Teti, Elsevier, 2023.","apa":"Gräßler, I., Mozgova, I., Pottebaum, J., Ott, M., Jung, P., & Hesse, P.

A key factor for the further establishment of LS is the expansion of the material portfolio with, for example, refreshable and halogen-free flame-retardant (FR) powder materials. Accordingly, various halogen-free FRs are investigated in this work and evaluated with respect to their use in LS. First, their decomposition behavior and mode of action are examined. Subsequently, the additives are dry blended with PA12 to investigate properties relevant for LS, such as particle morphology, thermal behavior and melt viscosity. Afterwards, test specimens for UL94 vertical flame-retardancy tests are produced by processing the dry blends on an EOS P3 LS system. Finally, the process stability of the process-aged powder blends is investigated by again examining the thermal behavior and melt viscosity."}],"type":"conference","citation":{"short":"F. Neitzel, I.

In order to extend the available material variety for the LS process, new ceramic-filled Polyamide 613 powders are investigated within the scope of this work. Here, the resulting properties from two different powder production methods are compared. One filled powder is produced by dry blending and the other powder with the same filler and filling ratio is produced by encapsulating the filler particles inside the polymer particles within the dissolution-precipitation process. It was found that encapsulating the filler particles can provide certain benefits for the processability, for example an improved powder flowability or better filler dispersion. However, encapsulating the filler also alters the thermal properties of the precipitated powder.

The standardized documentation of support structure information in technical drawings is intended to ensure a simple, clear and safe exchange of information between business units or different companies along the value chain. As a result a possible drawing entry of support structures was developed. To distinguish between different support structure types, a standardized depiction of geometrical information in a specification field is shown. The specification field gives a detailed description of the support structure type, the geometry as well as the connection to the part and the building platform.

The raw material is a polymer powder which is melted layerwise by the use of laser energy. Especially for the production of single parts, small series, individualized and complex structures, the technology is yet established in few branches. However, inhomogeneous and hardly controllable thermal effects during manufacturing limit the build reproducibility. The present work focuses on temperatures within so-called part cakes, their time dependency and their influence on process quality. Therefore, a temperature measurement system is implemented into a commercial laser sintering machine. Based on the experimental data a model to simulate heat transfer within part cakes is set up. Individual thermal histories during processing are successfully correlated with position dependent powder ageing effects. Another focus is on the analysis of a recycling optimized material. First results of correlations between thermal histories and part properties are shown in order to provide an outlook to further research. The data and knowledge gained through this work can be used to understand thermal effects in greater depth and to increase the process quality via optimizations.","lang":"eng"}],"user_id":"71545","publisher":"Shaker Verlag GmbH","author":[{"first_name":"Stefan","full_name":"Josupeit, Stefan","last_name":"Josupeit"}],"keyword":["Additive Manufacturing","Polymer Laser Sintering","Polymer Science"],"volume":11,"status":"public","date_created":"2021-09-21T11:23:29Z"}]
