    1. 55. A NON-DESTRUCTIVE METHOD FOR SURFACE ROUGHNESS MEASUREMENT AT INACCESSIBLE SPOTS ON AS-BUILT LASER POWDER BED FUSED SURFACES
      Ms Laura Wirths (Universität der Bundeswehr München)

      AM Process- and Quality Control
      Oral Presentation
      Laser Powder Bed Fusion (L-PBF) is an additive manufacturing process for the production of complex high quality metal parts. The surface roughness has an important impact on the mechanical behavior like crack initiation or fatigue life. Especially for complex geometries with its large amount of internal surfaces it is not possible to improve all surfaces by post-processing or even to determine...

    2. 1. INVESTIGATION OF THE INFLUENCE OF POWDER MOISTURE ON THE SPREADABILITY USING THE SPREADING TESTER
      Mr Marco Mitterlehner (TU Wien)

      AM Process- and Quality Control
      Oral Presentation
      Moisture is often regarded as one of the main reasons for poor processability of powders using L-PBF processes. To determine the influence of moisture on the spreadability a superalloy powder IN718 commonly used for SLM has been conditioned in two different states: once in the as-received and dry condition and once in a moist condition achieving by storing the powder four weeks in an...

    3. 56. LASER POWDER BED FUSION OF COPPER
      Mr Massimiliano Bonesso (INFN - Sezione di Padova)
      02/10/2020, 11:40
      AM Process- and Quality Control
      Oral Presentation
      At the National Institute for Nuclear Physics – Padova Division, the main research of the Development and Innovation on Additive Manufacturing Group is focused on developing new materials for the Laser Powder Bed Fusion (LPBF) technology. One of the major benefits of this technology is the possibility of fabrication of complex geometries and features in only one-step of production. In...

    4. 57. REFRACTORY METALS FABRICATED BY LASER POWDER BED FUSION
      Mr Pietro Rebesan (INFN Padua Division)
      02/10/2020, 12:00
      AM Process- and Quality Control
      Oral Presentation
      Refractory metals belong to the group of transition metals and they are also called “ultra-high temperature materials”. In addition to the high melting temperatures, they have properties that make them suitable for many applications. Tungsten, Molybdenum, and Tantalum produced by laser powder bed fusion process are the subjects of this study. Production of refractory metals by Additive...

    5. 34. SIMULATION-BASED SUPPORT STRUCTURES GENERATION FOR METAL 3D PRINTING PREDICTIVE LAYER PER LAYER THERMAL ANALYSIS AND EXPERIMENTAL VALIDATION
      Mr Carlos Lopez (Flanders Make)
      02/10/2020, 12:20
      AM Process- and Quality Control
      Oral Presentation
      Over the last years, additive manufacturing (AM) has transitioned from a system and materials to a complete end-to-end solution business. Printing cost becomes then a major factor to reduce in order to achieve the business goals. There are continuous attempts from additive manufacturing players to reduce material costs and increase process productivity such that AM becomes a key driver of...
