Additive manufacturing (AM) is becoming increasingly important for the energy sector, where lightweight, design-optimised parts can reduce system energy demand by up to 30 %. Polymer Powder Bed Fusion (PBF) is particularly relevant for producing housings, insulation, and composite components used in fuel cells, hydrogen systems, and thermal-management devices. However, the PBF process remains highly energy-intensive, and printed parts of ten show limited chemical and creep durability due to poorly understood stress-relaxation & chemistry phenomena. This project aims to drastically reduce the energy consumption and CO2 footprint of PBF by advancing Nylon 1016—a partially bio-based, chemically stable polyamide—as a sustainable replacement for PA12, while also improving its performance for energy-system components. The material will be further tested in biochemical, medical, engineering, and consumer sectors with an LCA analysis indicating energy/CO2 reduction vs PA12.
