In 2019, AMEXCI conducted a pre-study about “Advanced Polymers” aiming at providing an overview of different polymers available for Additive Manufacturing (AM) processes with a focus on engineering and high-performance polymers. Following the know-how attained from this prestudy about the overall introduction to AM thermoplastic materials and applicable AM processes, the company (OEM)-material compatibilities, and the comparison of mechanical properties of different available materials, in between spring and autumn 2020 AMEXCI conducted a follow-up project regarding mechanical properties of technical polymers initiated primarily with highperformance polymer, Polyether ketone ketone (PEKK), i.e., Antero 800 NA from Stratasys.
