Special Issue Information

Dear Colleagues,

This Special Issue aims to provide a platform for researchers and practitioners to exchange the latest results and research ideas focusing on polymers additive manufacturing of sports and protective equipment. We invite original research articles on all polymer additive manufacturing processes, including materials extrusion, vat polymerization, powder bed fusion, and material jetting, to accelerate the development and production of innovative polymer-based sports gear and protective equipment. The advantages of polymers are axiomatic, while additive manufacturing processes offer design and optimization opportunities for maximum performance. This Special Issue focuses on the process–structure–property–performance interrelations of novel additively manufactured sports and protective gears. Additionally, emphasis will be on the 3D printing of synthetic replacements of biological tissues, prostheses, and biomimetics.

Head impacts are a major concern in contact sports and sports with high-speed mobility due to the prevalence of head trauma events and their dire consequences. Surrogates of human heads are required in laboratory testing to safely explore the efficacy of impact-mitigating mechanisms. This work proposes using polymer additive manufacturing technologies to obtain a substitute for the human skull to be filled with a silicone-based brain surrogate. This assembly was instrumentalized with an Inertial Measurement Unit. Its performance was compared to a standard Hybrid III head form in validation tests using commercial headgear. The tests involved impact velocities in a range centered around 5 m/s. The results show a reasonable homology between the head substitutes, with a disparity in the impact response within 20% between the proposed surrogate and the standard head form. The head surrogate herein developed can be easily adapted to other morphologies and will significantly decrease the cost of the laboratory testing of head protection equipment, all while ensuring the safety of the testing process.
