Investigation and Optimization of Thermoplastic Material by Fused Deposition Modeling

Additive manufacturing is a booming technology nowadays. This helps to create some complicated shapes of the product. ASTM-D785-03 standard is used to create two different test specimens by fused deposition method (FDM). The parameters are layer thickness; infill density and infill pattern. After the printing is completed, the specimens are subjected to the mechanical test. Hardness is the material property that enables it to resist penetration, scratching, indentation and plastic deformations. In this project hardness of the thermoplastic (nylon and polycarbonate) material fabricated under different FDM process parameters is tested by Rockwell hardness test. Once the tests are completed, the results are taken for optimization through the use of Minitab software. © 2023. Carbon Magics Ltd.
