Dr Richard Görgl (JOANNEUM RESEARCH)30/09/2020, 15:00Laser Melting, Electron Beam Melting & Direct Energy Deposition ProcessesOral PresentationAn introduction into L-DED (also often known as Laser Metal Deposition - LMD) will be given by discussing the principles and a few applications. Emphasis is laid on the use of the Siemens NX Additive Manufacturing Add-on, which was formerly developed exclusively for DMG Mori and is openly sold for any systems since end of 2019. This software package for path-planning was then immediately...Go to contribution page

Mr John Meuthen (RHP Technology GmbH)30/09/2020, 15:20Laser Melting, Electron Beam Melting & Direct Energy Deposition ProcessesOral PresentationLight weight alloys, but also super alloys are widely used in aerospace industries for large parts. On the one hand the market e.g. for titanium is growing 3.8 % per year to $5.4 Billion in 2030, on the other hand high buy-to-fly ratios of typically 70% due to machining produces incredible amounts of expensive waste. Metal additive manufacturing processes as powder bed fusion give the chance...Go to contribution page

Mr Adrien Mouchard (Lufthansa Technik Turbine Shannon), Mr David Tanner (Bernal Institute, University of Limerick)30/09/2020, 16:10Laser Melting, Electron Beam Melting & Direct Energy Deposition ProcessesOral PresentationWhile already widespread for cladding, the Laser Blown Powder process is also becoming a major tool for 3D printing, with applications such as engine turbine repair. Some of them include deposition of thin-walled structure over a substrate with highly variable topography. Resulting deposition angles can affect the final wall geometry and could be detrimental for thin structures with tight...Go to contribution page

Mr Benjamin Meier (Joanneum Research Materials)30/09/2020, 16:30Laser Melting, Electron Beam Melting & Direct Energy Deposition ProcessesOral PresentationAs all technical production processes, every additive manufacturing technology offer advantages and drawbacks. While laser powder bed fusion (L-PBF) offers high precision and fine details, Direct Energy Deposition (DED) offers the possibility of creating large parts with high build rates. Aim of this study is to investigate material properties of hybrid parts made from Ti6Al4V by these two...Go to contribution page

Mr Marco Mitterlehner (TU Wien)30/09/2020, 17:10Laser Melting, Electron Beam Melting & Direct Energy Deposition ProcessesOral PresentationMoisture is often claimed to be one of the main reasons for poor processability of powders when using L-PBF processes. To determine the influence of moisture on the processability, gas atomized superalloy powder IN718 has been printed in two parallel runs: once in the as-received and dry condition and once after four weeks of storage in an atmosphere containing a relative humidity of 75 %....Go to contribution page

Mr Rudolf Gradinger (LKR Leichtmetallkompetenzzentrum Ranshofen GmbH)01/10/2020, 09:40Laser Melting, Electron Beam Melting & Direct Energy Deposition ProcessesOral PresentationThe great acceptance of additive manufacturing in tool making business was to a significant extent spurred by the opportunities to create complex shaped, 3D oriented internal cooling channels in tool inserts. These benefits were mainly achieved with Powder-bed technologies, providing reduced cycle times in e.g. injection moulding. Further achievements were made in post-treatment of 3D-printed...Go to contribution page

Mr Tobias Pichler (Fraunhofer Institute for Laser Technology ILT)01/10/2020, 10:00Laser Melting, Electron Beam Melting & Direct Energy Deposition ProcessesOral PresentationAdditive manufacturing using Laser Powder Bed Fusion (LPBF) provides breakthrough new capabilities in the fabrication of metallic components for a variety of applications. Nevertheless, major challenges remain. These include long process times, limited process robustness and thermal stress. Currently, LPBF process parameters are set globally for the entire part to be build, and do not take...Go to contribution page
