title = "Impact Resistance of Additively Manufactured Polymeric Materials for Biomedical Applications",
abstract = "This paper studies the impact resistance of nine polymeric materials to be used in orthosis manufacturing. The study aims to understand the behaviour of these materials under different conditions to improve their performance and durability. The materials were additive manufactured in both vertical and horizontal directions, and their impact properties were evaluated through Charpy pendulum impact tests. The tests were conducted in air and wet environment to simulate native conditions, dry, and sweat, respectively. Results show that the impact resistance of the materials is influenced by material type, printing direction, and environmental conditions. Nylon 12 demonstrates superior impact resistance. ULTEM{\texttrademark} 9085 exhibited a clear anisotropic behaviour with significantly different absorbed energy between the vertically and horizontally printed samples. The immersion in artificial sweat (wet environment) reduced the absorbed energy, which was more pronounced for longer immersion times. The fracture surface analysis revealed different failure mechanisms for the different materials ranging from ductile to brittle failure.",
