“…Owing to the simple shaping capabilities, microcomponents made from silicon or polymers can be realized easily by exploiting the different micro‐electro‐mechanical systems and replication techniques like etching, lithography, or molding enabling mass production 1–3 . In the last decade, powder injection molding has been adapted to the necessities of microdimensions as a suitable fabrication method for the realization of metal and ceramic parts with structural details and accuracy in the micrometer range 4,5 . Especially in case of molding of microsized or high‐aspect‐ratio microstructures (long‐flow length‐to‐width ratio), commercial feedstocks cannot be applied any more.…”

The effect of four different fatty acids on the rheological behavior of polyethylene-paraffin-zirconia feedstocks was investigated systematically. The substitution of a small portion of the low-viscous paraffin by the fatty acid does not alter the binder viscoelastic flow characteristics. At high solid loads (50 and 55 vol%), the addition of small amounts of fatty acid surfactants causes a significant influence on the feedstocks flow properties. An optimized surfactant concentration around 2.2 mg/m 2 fillers' specific surface area could be estimated. From melt rheology experiments, a clear correlation between the fatty acid molecular extension and resulting feedstock viscosity could be derived.
