@article{22196, abstract = {{The influence of selective laser sintering (SLS) parameters on PA12 part properties is well known, but research on other materials is rare. One alternative material is a thermoplastic elastomer (TPE) called PrimePart ST that is more elastic and shows a distinct SLS processing behavior. It undergoes a three-dimensional temperature distribution during the SLS process within the TPE part cake. To examine this further, a temperature measurement system that allows temperature measurements inside the part cake is applied to TPE in the present work. Position-dependent temperature histories are directly correlated with the color and mechanical properties of built parts and are in very good agreement with artificial heat treatment in a furnace. Furthermore, it is clearly shown that the yellowish discoloration of parts in different intensities is not only temperature dependent but also influenced by the residual oxygen content in the process atmosphere. Nevertheless, the discoloration has no influence on the mechanical part properties.}}, author = {{Kummert, Christina and Josupeit, Stefan and Schmid, Hans-Joachim}}, journal = {{Journal of Minerals, Metals and Materials Society}}, number = {{3}}, pages = {{425--430}}, publisher = {{Springer}}, title = {{{Thermoplastic Elastomer Part Color as Function of Temperature Histories and Oxygen Atmosphere During Selective Laser Sinterung}}}, doi = {{10.1007/s11837-017-2658-2}}, volume = {{70}}, year = {{2018}}, } @inproceedings{22430, author = {{Urbanek, Stefan and Ponick, Bernd and Taube, Alexander and Hoyer, Kay-Peter and Schaper, Mirko and Lammers, Stefan and Lieneke, Tobias and Zimmer, Detmar}}, booktitle = {{Conference paper, 2018 IEEE Transportation Electrification Conference and Expo (ITEC), Juni 2018, DOI: 10.1109/ITEC.2018.8450250}}, title = {{{Additive Manufacturing of a Soft Magnetic Rotor Active Part and Shaft for a Permanent Magnet Synchronous Machine}}}, year = {{2018}}, } @inproceedings{22433, author = {{Tominski, Johannes and Lammers, Stefan}}, booktitle = {{14th PERMAS Users' Conference}}, isbn = {{978-3-926494-18-4}}, title = {{{Software-assisted design check of additive manufactured components}}}, doi = {{https://www.semanticscholar.org/paper/METHOD-FOR-A-SOFTWARE-BASED-DESIGN-CHECK-OF-Tominski-Lammers/83e141f55b33041ade5e661958b449047d6f026e#extracted}}, volume = {{14}}, year = {{2018}}, } @inproceedings{22434, abstract = {{This paper reports on the experimental development and the theoretical analysis of the scanning laser epitaxy (SLE) process that is currently being investigated and developed at the Georgia Institute of Technology. SLE is a laser-based manufacturing process for deposition of equiaxed, directionally solidified and single-crystal nickel superalloys onto superalloy substrates through the selective melting and re-solidification of superalloy powders. The thermal modeling of the system, done in a commercial CFD software package, simulates a heat source moving over a powder bed and considers the approximate change in the property values for consolidating CMSX-4 nickel superalloy powder. The theoretical melt depth is obtained from the melting temperature criteria and the resulting plots are presented alongside matching experimental micrographs obtained through cross-sectional metallography. The influence of the processing parameters on the microstructural evolution, as evidenced through observations made from the micrographs, is discussed.
