Regarding this, buckling deformation which is caused by thermal stress is one of the undesired mechanical properties which must be alleviated. As buckling deformation is more observable in hard to process materials, silver is selected to be studied theoretically and experimentally for this paper. Different scanning strategies are utilized and a Finite Element Method (FEM) is applied to calculate the temperature gradient in order to determine its effect on the buckling deformation of the objects from experiments.}, language = {en} } @article{GebhardtFateri2013, author = {Gebhardt, Andreas and Fateri, Miranda}, title = {3D printing and its applications}, series = {RTejournal - Forum f{\"u}r Rapid Technologie}, volume = {10}, journal = {RTejournal - Forum f{\"u}r Rapid Technologie}, number = {1}, publisher = {Fachhochschule Aachen}, address = {Aachen}, issn = {1614-0923}, url = {http://nbn-resolving.de/urn:nbn:de:0009-2-35626}, year = {2013}, abstract = {Eine zunehmende Anzahl von Artikeln in Publikumszeitschriften und Journalen r{\"u}ckt die direkte Herstellung von Bauteilen und Figuren immer mehr in das Bewusstsein einer breiten {\"O}ffentlichkeit.

Especially in the field of dentistry, jewelry and related branches that require individualized or even one-of-a-kind products, the direct digital manufacturing process opens up new ways of design and manufacturing. In these fields, mostly small and medium sized businesses (SME) are operating which do not have sufficient human and economic resources to invest in this technology. But to stay competitive, the application of AM can be regarded as a necessity. In this situation a new desktop machine (Realizer SLM 50) was introduced that cost about 1/3 of a shop floor SLM machine and promises small quality parts. To find out whether the machine really is an alternative for SMEs the University of Applied Science, Aachen, Germany, designed, build and optimized typical parts from the dentistry and the jewelry branches using CoCr and silver material, the latter being new with this application. The paper describes the SLM procedure and how to find and optimize the most important parameters. The test is accompanied by digital simulation in order to verify the build parameters and to plan future builds. The procedure is shown as well as the resulting parts made from CoCr and silver material.}, language = {en} } @inproceedings{FateriGebhardtKhosravi2013, author = {Fateri, Miranda and Gebhardt, Andreas and Khosravi, Maziar}, title = {Experimental investigation of selective laser melting of lunar regolith for in-situ applications}, series = {ASME 2013 International Mechanical Engineering Congress and Exposition : San Diego, California, USA, November 15-21, 2013.
