  text: The Arburg Plastic Freeforming (APF) is an additive manufacturing process
    which allows the production of three-dimensional thermoplastic components in layers.
    The components are produced by depositing fine, molten plastic droplets. The main
    advantage of the APF is the open-parameter control of the associated machine system.
    Thus, the process parameters can be optimized for individual applications. A special
    and new application of the APF is the production of interconnecting porous structures.
    As this is a novel approach with this manufacturing process, the general producibility
    and reproducibility must first be proven. Therefore, the relevant process parameters
    with an influence on the open-pored structures are identified. The volume of the
    individual plastic droplets, the distance between the droplets and the layer thickness
    are the three decisive influencing factors. With the use of analysis methods,
    the free spaces created in the structure are described by a uniformly constructed,
    interconnected pore structure. This means that the pores are interconnected in
    three dimensions. Reproducibility is evaluated by repeated production and thru
    the changed conditions during the manufacturing process. In addition, the multiplication
    and a change of geometry are evaluated in such a way that there is no influence
    on the pore size. Irregularities when depositing the first layer are caused by
    unevenness of the building platform. A suitable test arrangement is set up to
    determine the liquid permeability. A characteristic value is determined to describe
    the permeability to liquids.
