  text: In the laser sintering technology, the semi-crystalline polymer material is
    exposed to elevated temperatures during processing, which leads to serious material
    ageing for most materials. This has already been investigated intensively by various
    authors. However, the ageing of the material at ambient temperatures during shelf
    life has not been the focus so far. The need to analyse the shelf life can be
    derived from an ecological and economic point of view. This work is focusing on
    the shelf life of PA2200 (PA12). To reduce the potential influences of powder
    production fluctuations, two different powder batches stored for 5.5 years and
    6.5 years are investigated and compared to a reference powder produced 0.5 years
    before these investigations. Multiple powder analyses and part characterisations
    have been performed. A significant yellowing and molecular chain length reduction
    can be derived from the measurement results. Whereas the influence on mechanical
    part performance was minor, the parts built with the stored powders are more yellowish.
    As it is most likely that this is due to the consumption of polyamide stabilisers,
    it can be assumed that these parts will be subject to significantly faster ageing.
    Therefore, it is still not recommended to use the stored powders for critical
    parts or light intense and humid environments.

  text: Confidence in additive manufacturing technologies is directly related to the
    predictability of part properties, which is influenced by several factors. To
    gain confidence, online process monitoring with dedicated and reliable feedback
    is desirable for every process. In this project, a powder bed monitoring system
    was developed as a retrofit solution for the EOS P3 laser sintering machines.
    A high-resolution camera records each layer, which is analyzed by a Region-Based
    Convolutional Neural Network (Mask R-CNN). Over 2500 images were annotated and
    classified to train the network in detecting defects in the powder bed at a very
    high level. Each defect is checked for intersection with exposure areas. To distinguish
    between acceptable imperfections and critical defects that lead to part rejection,
    the impact of these imperfections on part properties is investigated.

  text: By monitoring the recoating process within polymer laser sintering production,
    it was shown that multiple powder-spread-flaws can be detected. Those groove-like
    flaws are expected to be the result of agglomerates jamming between the recoater
    and the last powder layer. This work is analyzing the interaction between powder-spread-flaws
    and part properties, showing the influence of the recoating process on the performance
    of laser sintering parts. Therefore, artificial powder-spread-flaws are applied
    to the build jobs of tensile test specimens which are measured and analyzed regarding
    the elongation at break, strength and fracture position. For the characteristics
    of the flaws, the artificial grooves are varied in depth and width. Furthermore,
    the position of the flaw is changed form mid part to close to surface areas. It
    was shown, that several flaws are visible at the part surface, resulting in stress
    concentration and reduced performance. But there are as well parts with flaw-layers,
    which are not visible after the build process on the part. Those parts can have
    significantly reduced mechanical properties as well.

  text: Zuverlässige, wiederholbare Bauteileigenschaften sind unabdingbar um das Herstellungsverfahren
    Polymer Lasersintern im industriellen Prozess-Portfolio vieler Firmen aufnehmen
    zu können. Einige Unternehmen und Institute haben sich daher in jüngster Zeit
    mit dem Thema der reproduzierbaren Bauteileigenschaften beschäftigt. Mit der hier
    vorgestellten und angewandten Methodik wird nicht nur der Prozessablauf vom Bauteil
    bis zu Nachbearbeitung betrachtet, sondern auch die Maschinenperformance in einem
    Ringversuch und über einen längeren Zeitraum geprüft. Rückgrat dieser Untersuchung
    bildet hierbei der aus der Six Sigma Lehre stammende DMAIC (Define - Measure -
    Analyse - Improve - Control) Verbesserungszyklus. Hierfür wird ein Standard-Prozess
    definiert. Diesem folgend werden die für die Industrie oder den Anwender interessanten
    Messungen aufgenommen und analysiert. Anschließend wird der Prozess sowie die
    Messmethodik optimiert und auch Kontrollmethoden definiert. Für die Anwendung
    der entwickelten Methodik wird exemplarisch der Maschinentyp EOS P396 mit PA2200
    untersucht. Daten für die Bestimmung der Mechanik, der Optik und der Haptik sowie
    für die Dimensionen und die Bauteildichte werden als Qualitätskriterium aufgenommen
    und über einen längeren Zeitraum analysiert. Weiteres Ziel ist es, den Messaufwand
    zu reduzieren und die Qualitätssicherung im Serienbtrieb zu gewährleisten.

  text: Structural parts for aviation have very high demands on the development and
    production process. Therefore, the entire process must be considered in order
    to produce high-quality AM metal parts. In this case study, a conventional part
    was selected to be optimized for AM. The process presented includes component
    selection, design improvement with a novel approach for topology optimization
    based on the AMendate algorithm as basis of MSC Apex Generative Design,component
    production on a SLM 250 HL and post-processing including heat treatment and surface
    smoothing. With the topology optimization a weight reduction of ~60 % could be
    realized, whereby the stress distribution is more homogeneous. Furthermore, the
    challenges of support optimization and post-processing have to be addressed, in
    order to produce competitive parts.

  text: Additive Manufacturing (AM) is a game changing production technology for aerospace
    applications. Fused deposition modeling is one of the most widely used AM technologies
    and recently has gained much attention in the advancement of many products. This
    paper introduces an extensive review of fused deposition modeling and its application
    in the development of high performance unmanned aerial vehicles. The process methodology,
    materials, post processing, and properties of its products are discussed in details.
    Successful examples of using this technology for making functional, lightweight,
    and high endurance unmanned aerial vehicles are also highlighted. In addition,
    major opportunities, limitations, and outlook of fused deposition modeling are
    also explored. The paper shows that the emerge of fused deposition modeling as
    a robust technique for unmanned aerial vehicles represents a good opportunity
    to produce compact, strong, lightweight structures, and functional parts with
    embedded electronic.
