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.","lang":"eng"}],"_id":"24101","page":"467-474","editor":[{"last_name":"Bourell","first_name":"David","full_name":"Bourell, David"}],"user_id":"45537","conference":{"end_date":"2021-08-04","location":"Austin, Texas, USA","start_date":"2021-08-02","name":"2021 Annual International Solid Freeform Fabrication Symposium (SFF Symp 2021)"},"status":"public","oa":"1","citation":{"bibtex":"@inproceedings{Moritzer_Hecker_Elsner_Hirsch_2021, title={Investigations for the Optimization of Visual and Geometrical Properties of Arburg Plastic Freeforming Components}, DOI={<a href=\"https://doi.org/10.26153/tsw/17567\">10.26153/tsw/17567</a>}, booktitle={Proceedings: 2021 Annual International Solid Freeform Fabrication Symposium (SFF Symp 2021)}, author={Moritzer, Elmar and Hecker, Felix and Elsner, Christian Lennart and Hirsch, André}, editor={Bourell, David}, year={2021}, pages={467–474} }","ama":"Moritzer E, Hecker F, Elsner CL, Hirsch A.

The components are generated by depositing fine, molten plastic droplets. One of the main advantages of the APF process is the open machine control. Thus, the process parameters can be adapted and optimized for the individual applications. The optimization is carried out on the basis of a variation of the process parameters using a statistical design of experiments. Relevant process parameters are the layer thickness, the form factor, the raster and delta angle as well as the overlap between the contour and the filling of a layer. In addition, the nozzle and build chamber temperatures are varied. Using this procedure, the effects of the influencing parameters on the mechanical properties and the interactions between the influencing parameters are analyzed and converted into mathematical models. On the basis of the results and the models, guidelines will be developed to assist the user of APF technology in the systematic process configuration for their own applications. The material used is ABS, one of the most frequently used amorphous thermoplastics in additive manufacturing. The mechanical properties are determined on the basis of tensile tests and the characteristic values tensile strength, elongation at break and Young's modulus. The results should show the performance of the APF technology in regard to the mechanical properties."}],"date_created":"2021-05-07T13:23:23Z","department":[{"_id":"219"},{"_id":"624"},{"_id":"367"},{"_id":"321"},{"_id":"9"}],"type":"conference","author":[{"last_name":"Moritzer","first_name":"Elmar","full_name":"Moritzer, Elmar","id":"20531"},{"id":"27599","first_name":"André","last_name":"Hirsch","full_name":"Hirsch, André"},{"id":"45537","last_name":"Hecker","first_name":"Felix","full_name":"Hecker, Felix"}],"year":"2019","status":"public","title":"Process Parameter Optimization to Improve the Mechanical Properties of Arburg Plastic Freeformed Components","intvolume":"        30","date_updated":"2024-01-15T12:01:40Z","language":[{"iso":"eng"}],"_id":"22041","page":"705-714","volume":30,"doi":"http://dx.doi.org/10.26153/tsw/17308","user_id":"45537"}]
