However, the manufacturability of lattice structures and mechanical properties for polymer laser sintering are quite unknown yet. To examine the manufacturability, sandwich structures with different cell types, cell sizes and lattice bar widths were designed, manufactured and evaluated. A decisive criterion is for example a sufficient powder removal. In a second step, manufacturable structures were analyzed using four-point-bending tests. Experimental data is compared to the density of the lattice structures and allows for a direct comparison of different cell types with varied geometrical attributes. The results of this work are guidelines for the design and dimensioning of laser sintered lattice structures.}}, author = {{Josupeit, Stefan and Delfs, Patrick and Menge, Dennis and Schmid, Hans-Joachim}}, booktitle = {{27th Annual International Solid Freeform Fabrication Symposium }}, pages = {{2077--2086}}, title = {{{Manufacturability and Mechanical Characterization of Laser Sintered Lattice Structures}}}, doi = {{http://utw10945.utweb.utexas.edu/sites/default/files/2016/166-Josupeit.pdf}}, volume = {{27}}, year = {{2016}}, } @article{22185, abstract = {{The layered structure of Additive Manufacturing processes results in a stair- stepping effect of the surface topographies. In general, the impact of this effect strongly depends on the build angle of a surface, whereas the overall surface roughness is additionally caused by the resolution of the specific AM process. The aim of this work is the prediction of the surface quality in dependence of the building orientation of a part. These results can finally be used to optimize the orientation to get a desired surface quality. As not all parts of the component surface are equally important, a preselection of areas can be used to improve the overall surface quality of relevant areas. The model uses the digital AMF format of a part. Each triangle is assigned with a roughness value and by testing different orientations the best one can be found. This approach needs a database for the surface qualities. This must be done separately for each Additive Manufacturing process and is shown exemplarily with a surface topography simulation for the laser sintering process.}}, author = {{Delfs, Patrick and Tows, Marcel and Schmid, Hans-Joachim}}, isbn = {{2214-8604}}, journal = {{Additive Manufacturing}}, number = {{12, Part B}}, pages = {{214--320}}, publisher = {{Elsevier}}, title = {{{Optimized build orientation of additive manufactured parts for improved surface quality and build time}}}, doi = {{10.1016/j.addma.2016.06.003}}, volume = {{2}}, year = {{2016}}, } @inproceedings{22190, author = {{Delfs, Patrick and Schmid, Hans-Joachim}}, booktitle = {{Fraunhofer Direct Digital Manufacturing Conference}}, isbn = {{978-3-8396-1001-5}}, pages = {{411--414}}, title = {{{Extended Analysis of the Surface Topography of Laser Sintered Polymer Parts }}}, doi = {{https://www.bookshop.fraunhofer.de/buch/fraunhofer-direct-digital-manufacturing-conference-ddmc-2016/245111#}}, volume = {{3}}, year = {{2016}}, } @inproceedings{22194, author = {{Josupeit, Stefan and Schmid, Hans-Joachim}}, booktitle = {{International Congress on Particle Technology (PARTEC) }}, title = {{{Thermal properties of polyamide 12 powder for application in laser sintering}}}, year = {{2016}}, } @inproceedings{22200, abstract = {{In the polymer laser sinter process, part quality depends on many influencing factors along the process chain.
