  text: Polymer laser sintering is one of the most important additive manufacturing
    technologies for the tool-less production of three-dimensional prototypes and
    end-use parts. In this process, parts are manufactured layerwise out of a polymer
    powder by laser exposure. After the building process, these parts are located
    within a loose bulk powder cake. Due to long process times and high process temperatures,
    this powder ages thermally, which reduces the recyclability of the material. As
    a result, mixtures of used and virgin powder ("refreshed" powder) with a mixture
    ratio of approximately 50% are commonly used in the industry. The goal of this
    work is to determine the exact influence of different powder ages on resulting
    part quality characteristics, especially the mechanical behavior and the surface
    quality. Therefore, refreshed powder with different qualities adjusted by the
    melt volume rate (MVR) was processed along a defined process quality chain. To
    analyze the part qualities, mechanical tensile and profilometer tests were performed.
    The focus is on an application-oriented test set-up to ensure the usability of
    the results in the industry. The material used is polyamide 12 (PA 2200) processed
    on an EOSINT P395 laser sintering system from EOS GmbH, Krailling, Germany.
