Abstract or Description

  Additive manufacturing is an actively growing industry, due to the advantages it provides to design, manufacturing, and prototyping. Fused deposition modeling (FDM) being the most common because of how accessible and simple these printers are to operate different types of thermoplastic materials to be printed together. FDM technology allows both materials to be printed together. Combing two materials together can provide material properties that are not obtainable using a single material . The materials used in this experiment are 95A TPU and PLA. TPU is a softer elastic material while PLA is a stiff brittle material. Gyroid structures are a type of lattice structure that is used to lightweight parts without decreasing the strength of a part, gyroid structures may also offer better mechanical properties like energy absorption. Combing both of these properties can allow parts to have varying kinds of mechanical properties. The material properties of these samples are obtained by doing compression test, the data is then analyzed using polynomial interpolation to develop a neural network that will find the relative density and material distribution of a part based on mechanical properties that are desired.
