  text: <jats:title>Abstract</jats:title><jats:p>Further innovation in the field of
    selective laser sintering (SLS) is strongly connected to the availability of new
    materials since the market is dominated by polyamide 12 (&gt;90%). The aim of
    this publication is to develop a descriptive model for the droplet formation process
    in a Filament Extension Atomizer to predict the applicability to exploit further
    polymers for the SLS process. The feasibility was tested, investigated and characterized
    using a “Dripping out of a nozzle” setup for uniaxial extension. The droplet formation
    process was then observed via high-speed camera imaging and classified for certain
    parameters. The experiments were carried out using semi-diluted polyethylene oxide
    (600–4000 kg/mol), glycerol and water solutions as model fluids. Driven by the
    Plateau-Rayleigh instability, different types of spherical droplets were observed
    and various droplet formation mechanisms demonstrated and analyzed. Based on the
    experimental results, a predictive model is derived to describe various essential
    parameters.</jats:p>
