An overview of various additive manufacturing techniques and the range of rubber-like materials that maybe produced is given. The study revolves around determining the working characteristics and accuracy of the results of Thermoplastic Polyurethane (TPU) printed product. It explores the introduction of hyperelastic material models and explains the curve fitting procedure used to precisely depict these materials' behaviour under various stresses. In order to fully understand how the material responds to different situations, a key component of the study is the process of fitting the parameters of the material model using various datasets of test loads from compression and tension test results. Subsequently, by performing finite elements analysis on a printed TPU product, the study validates the accuracy of the obtained results, guaranteeing the validity and authenticity of the conclusions.52enAdditive ManufacturingHyperelastic material modelsTensile and compression testFinite element analysisEngineering Sciences::EngineeringHozzáférhető a 2022 decemberi felsőoktatási törvénymódosítás értelmében.
