Experimental and numerical investigation of the light scattering of the 3D printed parts

Anisoprint is a forefront technology in the realm of 3D printing and has ushered in a transformative era in composite material fabrication. The synergistic fusion of Anisoprint's 3D printing technology with laser transmission welding has enabled the creation of complex structures featuring carbon fiber reinforcements along all three spatial axes. This innovative amalgamation empowers the production of components distinguished by their unparalleled strength and precision. In the pursuit of this objective, the integration of transparent thermoplastic windows within 3D-printed components has been employed as conduits for laser beams during the welding process. Nevertheless, the interaction between laser beams and these transparent windows introduces a phenomenon characterized by beam diffusion, primarily attributed to the intrinsic porosity inherent in the 3D printing process. Within the scope of this study, an in-depth examination of laser beam diffusion within 3D-printed carbon fiber components is undertaken. This endeavor encompasses the application of micro-tomography to meticulously construct a comprehensive mesh representing the microstructural intricacies of the transparent section. Leveraging this mesh, ray tracing simulations are conducted to elucidate laser beam behavior. Subsequently, a comparative analysis is conducted between these numerical outcomes and experimental observations, involving the scrutiny of laser beam photographs as they traverse the printed component. This research aspires to enhance our comprehension of the intricate dynamics governing laser beam interactions within Anisoprinted structures. Ultimately, this will contribute to the refinement of laser welding processes and foster the advancement of more efficient and dependable manufacturing methodologies for composite materials.
