  text: The temperature distribution and history within laser sintered part cakes
    is an important aspect regarding the process quality and reproducibility of the
    polymer laser sintering process. Especially the temperature history during the
    build and cooling phase is decisive for powder ageing effects and the development
    of part quality characteristics. In this work, a measurement system for three-dimensional
    in-process temperature measurements is set up and the influence of different parameters
    on the inner part cake temperature distribution and history is analyzed. Important
    factors are not only geometrical build job parameters like the part packing density
    and build height, but also process parameters like the layer thickness and bulk
    powder density. Individual in-process temperature profiles at different positions
    within a part cake are finally correlated with powder ageing effects. The results
    of this work help to understand the temperature history dependency of powder and
    part properties and can therefore be used to develop optimized process controls.
