| Abstract Scope |
The world of 3D printing has seen a huge transformation with the introduction of multi-material printing. This opens up endless possibilities for creativity with material combinations and design options. Our research aims to explore the potential of dual thermoplastic materials, material gradation, and nozzle residence time in multi-material 3D printing. We want to expand the knowledge in this field and investigate areas that have not yet been explored. Most studies have focused on hardware aspects, without taking into account the critical dimensions of material gradation, nozzle residence time, and their effects on 3D printed components. Our research is divided into two parts. In part 1, we aim to determine whether in-situ mixing can achieve polymer blending, which could enhance interfacial bonding and mechanical properties. We hypothesize that in-situ mixing can facilitate the blending of two materials at a molecular level, thereby improving interlayer bonding. The methodology includes various tests such as material selection, printing parameter optimization, variation of residence time, mechanical testing, chemical analysis, and thermal analysis. |
