Front Cover: Polypropylenes for 3D printing are synthesized based on a customized split‐plot design. The study investigate homo‐ and copolymers, with varying comonomer content and type. Furthermore, the amount of donor and the hydrogen partial‐pressure are observed factors. After evaluation and optimization of the analyzed material properties, filaments of the most promising polymers are produced and successfully used in fused filament fabrication printing. This is reported by Gunnar Spiegel and Christian Paulik in article 1900044.
