  • 3D-printed individual labware in biosciences by rapid prototyping: In vitro biocompatibility and applications for eukaryotic cell cultures 
    Lücking, Tim H.; Sambale, Franziska; Schnaars, Birte; Bulnes-Abundis, David; Beutel, Sascha; Scheper, Thomas (Weinheim : Wiley-VCH Verlag, 2014)
    Three-dimensional (3D) printing techniques are continuously evolving, thus their application fields are also growing very fast. The applications discussed here highlight the use of rapid prototyping in a dedicated biotechnology ...
  • Additive manufacturing of copper vertical interconnect accesses by laser processing 
    Overmeyer, Ludger; Olsen, Ejvind; Hoffmann, Gerd-Albert (Oxford : Elsevier, 2021)
    This paper introduces a new manufacturing process for vertical interconnect accesses (VIA). In contrast to industrially established VIA metallization technologies, the presented approach takes place without any chemical ...
  • Combination of Laser and Thermal Sintering of Thermoelectric Ca3Co4O9 Films 
    Wolf, Mario; Rehder, Lena; Steinbach, Frank; Abt, Marvin; Hinterding, Richard; Overmeyer, Ludger; Feldhoff, Armin (Weinheim : Wiley-VCH Verl., 2021)
    The manufacturing technology of thermoelectric materials is laborious and expensive often including complex and time-intensive preparation steps. In this work, a laser sintering process of the oxide-based thermoelectric ...
  • Finite element simulation of sintering of metal-bonded grinding wheels 
    Denkena, B.; Krödel, A.; Liu, Y.; Kempf, F.; Kostka, M. (Amsterdam [u.a.] : Elsevier, 2021)
    The grinding wheel properties porosity, particle distribution and the grain holding force influence the surface roughness of the machined workpiece and the performance of the grinding process. These properties of a grinding ...
  • Functionality of laser-sintered shape memory micro-actuators 
    Dudziak, S.; Gieseke, M.; Haferkamp, H.; Barcikowski, S.; Kracht, D. (Amsterdam : Elsevier B.V., 2010)
    NiTi shape memory alloys are considered to be difficult to machine. Dimensional accuracy can hardly be met especially in micro-machining. Being a non-contact tool and therefore independent from machining forces, the laser ...
  • Impact of Hard Machining on Zirconia Based Ceramics for Dental Applications 
    Denkena, Berend; Breidenstein, Bernd; Busemann, Sarah; Lehr, Claudius Moritz (Amsterdam : Elsevier BV, 2017)
    Since the late 90s the use of zirconia based all-ceramic restorations increases. Many manufacturing steps are necessary, like pre-sintering, soft machining (pre-sintered condition), sintering and hard machining (fully ...
  • Manufacturing conditioned wear of all-ceramic knee prostheses 
    Denkena, Berend; Köhler, Jens; Turger, Anke; Helmecke, Patrick; Correa, Tomas A.; Hurschler, Christof (Amsterdam : Elsevier, 2013)
    To date, bioceramics have not been applied successfully in total knee joint endoprostheses. Sintered bioceramics can be machined only by grinding and polishing processes. Due to high quality requirements, there are significant ...
  • New perspectives in shake flask pH control using a 3D-printed control unit based on pH online measurement 
    Ude, Christian; Hentrop, Thorleif; Lindner, Patrick; Lücking, Tim H.; Scheper, Thomas; Beutel, Sascha (Amsterdam : Elsevier, 2015)
    Abstract Online pH control during microbial shake flask cultivation has not been established due to the lack of a practical combination of an online sensor system and an appropriate control unit. The objective of this ...
  • Optimization of anodic porous transport electrodes for proton exchange membrane water electrolyzers 
    Bühler, Melanie; Hegge, Friedemann; Holzapfel, Peter; Bierling, Markus; Suermann, Míchel.; Vierrath, Severin; Thiele, Simon (Cambridge : Royal Society of Chemistry, 2019)
    In this study we investigate the potential of porous transport electrode (PTE) based membrane electrode assemblies (MEAs) for proton exchange membrane water electrolysis. The focus is on the overpotential determining anodic ...
  • Production of chip breakers on cemented carbide tools using laser ablation 
    Denkena, Berend; Krödel, Alexander; Ellersiek, Lars; Murrenhoff, Marita (Amsterdam : Elsevier B.V., 2020)
    Chip breakers are essential for achieving reproducible and safe turning processes. In case of cemented carbide tools with standard ISO geometries, they are manufactured by form pressing before sintering. In form turning ...
