研究目的
To determine the material properties and material law suitable for describing the behavior of parts produced by additive manufacturing technologies, specifically SLS, and compare them with other technologies like OBJET Polyjet and FDM.
研究成果
The material behavior of parts produced by SLS technology is independent of the production direction and can be described by isotropic material law, unlike OBJET Polyjet and FDM technologies, which require orthotropic material law due to their direction-dependent material properties. The production technology significantly influences the load-bearing capacity of the product, necessitating consideration of printing direction behavior during the design procedure.
研究不足
The study is limited to the comparison of material properties from three specific additive manufacturing technologies and may not cover all possible materials or technologies in the field. The focus on tensile properties might not fully represent the material behavior under different loading conditions.
