The layer-wise manufacturing nature of AM enables fabrication of freeform geometries which cannot be fabricated using conventional manufacturing methods as a one part. Depending on how each layer is created and bonded to the adjacent layers, different AM methods have been developed. In this chapter, the basic terms, common materials, and different methods of AM are described, and their potential applications are discussed.}, language = {en} } @incollection{GebhardtHoetter2019, author = {Gebhardt, Andreas and Hoetter, Jan-Steffen}, title = {Rapid Tooling}, series = {CIRP Encyclopedia of Production Engineering}, booktitle = {CIRP Encyclopedia of Production Engineering}, publisher = {Springer}, address = {Berlin, Heidelberg}, isbn = {978-3-662-53120-4}, doi = {10.1007/978-3-662-53120-4}, pages = {39 -- 52}, year = {2019}, language = {en} } @article{KunkelGebhardtMpofuetal.2019, author = {Kunkel, Maximilian Hugo and Gebhardt, Andreas and Mpofu, Khumbulani and Kallweit, Stephan}, title = {Quality assurance in metal powder bed fusion via deep-learning-based image classification}, series = {Rapid Prototyping Journal}, volume = {26}, journal = {Rapid Prototyping Journal}, number = {2}, issn = {1355-2546}, doi = {10.1108/RPJ-03-2019-0066}, pages = {259 -- 266}, year = {2019}, language = {en} } @article{CosmaKesslerGebhardtetal.2020, author = {Cosma, Cosmin and Kessler, Julia and Gebhardt, Andreas and Campbell, Ian and Balc, Nicolae}, title = {Improving the Mechanical Strength of Dental Applications and Lattice Structures SLM Processed}, series = {Materials}, volume = {13}, journal = {Materials}, number = {4}, publisher = {MDPI}, address = {Basel}, issn = {1996-1944}, doi = {10.3390/ma13040905}, pages = {1 -- 18}, year = {2020}, abstract = {To manufacture custom medical parts or scaffolds with reduced defects and high mechanical characteristics, new research on optimizing the selective laser melting (SLM) parameters are needed. In this work, a biocompatible powder, 316L stainless steel, is characterized to understand the particle size, distribution, shape and flowability. Examination revealed that the 316L particles are smooth, nearly spherical, their mean diameter is 39.09 μm and just 10\% of them hold a diameter less than 21.18 μm. SLM parameters under consideration include laser power up to 200 W, 250-1500 mm/s scanning speed, 80 μm hatch spacing, 35 μm layer thickness and a preheated platform. The effect of these on processability is evaluated. More than 100 samples are SLM-manufactured with different process parameters. The tensile results show that is possible to raise the ultimate tensile strength up to 840 MPa, adapting the SLM parameters for a stable processability, avoiding the technological defects caused by residual stress. Correlating with other recent studies on SLM technology, the tensile strength is 20\% improved. To validate the SLM parameters and conditions established, complex bioengineering applications such as dental bridges and macro-porous grafts are SLM-processed, demonstrating the potential to manufacture medical products with increased mechanical resistance made of 316L.}, language = {en} } @inproceedings{GerhardsSchleserOttenetal.2019, author = {Gerhards, Benjamin and Schleser, Markus and Otten,, Christian and Schwarz, Alexander and Gebhardt, Andreas}, title = {Innovative Laser Beam Joining Technology for Additive Manufactured Parts}, series = {Conference Proceedings 72nd IIW Annual Assembly and International Conference, 7-12 July 2019, Bratislava}, booktitle = {Conference Proceedings 72nd IIW Annual Assembly and International Conference, 7-12 July 2019, Bratislava}, pages = {1 -- 8}, year = {2019}, language = {en} } @inproceedings{LuftGebhardtBalc2019, author = {Luft, Angela and Gebhardt, Andreas and Balc, Nicolae}, title = {Challenges of additive manufacturing in production systems}, series = {Modern technologies in manufacturing (MTeM 2019)}, volume = {299}, booktitle = {Modern technologies in manufacturing (MTeM 2019)}, number = {Article 01003}, doi = {10.1051/matecconf/201929901003}, pages = {6 Seiten}, year = {2019}, language = {en} } @book{GebhardtKesslerSchwarz2019, author = {Gebhardt, Andreas and Kessler, Julia and Schwarz, Alexander}, title = {Produktgestaltung f{\"u}r die additive Fertigung}, publisher = {Hanser}, address = {M{\"u}nchen}, isbn = {978-3-446-45285-5}, pages = {XVI, 266 Seiten : Illustrationen, Diagramme}, year = {2019}, language = {de} } @inproceedings{OttenGerhardsSchleseretal.2019, author = {Otten, Christian and Gerhards, Benjamin and Schleser, Markus and Schwarz, A. and Gebhardt, Andreas}, title = {Innovative Laserschweißtechnologie f{\"u}r additiv gefertigte Bauteile}, series = {Große Schweißtechnische Tagung}, booktitle = {Große Schweißtechnische Tagung}, publisher = {DVS-Media}, address = {D{\"u}sseldorf}, isbn = {978-3-96144-066-5}, pages = {150 -- 157}, year = {2019}, language = {de} } @article{BucurLazarescuPopetal.2019, author = {Bucur, Alexandru and Lazarescu, Lucian and Pop, Grigore Marian and Achimas, Gheorghe and Gebhardt, Andreas}, title = {Tribological performance of biodegradable lubricants under different surface roughness of tools}, series = {Academic Journal of Manufacturing Engineering}, volume = {17}, journal = {Academic Journal of Manufacturing Engineering}, number = {1}, issn = {1583-7904}, pages = {172 -- 178}, year = {2019}, language = {en} }
