- Comparative analysis between joining stacking based laser micro spot welding (JS-LMSW) and laser powder bed fusion (LPBF) for guided bone regeneration(Instituto Tecnológico y de Estudios Superiores de Monterrey, 2024-01) Morales Fierro, Alan Giovanni; Sandoval Robles, Jesús Alejandro; mtyahinojosa, emipsanchez; Cedeño Viveros, Luis Daniel; Rodríguez García, Aída; School of Engineering and Sciences; Campus Monterrey; García López, ErikaDental devices, such as periodontal membranes used in the Guided Bone Regeneration (GBR) treatment, need to be manufactured with specific requirements to reach the quality desired. In this project, a periodontal membrane was manufactured by Joining Stacking Based Laser Micro Spot Welding (JS-LMSW) and Laser Powder Bed Fusion (LPBF). The objectives of this project were to design a periodontal membrane based on an imaged-based tomography, to identify the parameters for JS-LMSW and LPBF, and to characterize dimensionally the membranes. For JS-LMSW, an experimental design was carried on by changing parameters such as time exposure (1, 4, 7, 10 ms) and power (160, 180, 200 W). It was observed that the samples with the best quality profile were 160W/1ms, 180W/7ms, and 200W/10ms. For LPBF, it wasn’t possible to obtain the membrane with the original measurements. Also, all the periodontal membrane samples were electropolished. It was possible to design a periodontal membrane from a real case, the parameters of JS-LMSW were identified, and electropolishing improved dimensionally some measurements of the membrane.
- Optimization of Dimensional Variation for Additive Manufacturing Using Response Surface Methodology Technique for Lattices Structure(Instituto Tecnológico y de Estudios Superiores de Monterrey, 2020-12-02) Betancourt Chacón, Diego Antonio; Sandoval Robles, Jesús Alejandro; puelquio/tolmquevedo; Hernández Luna, Alberto Abelardo; Rodríguez González, Ciro Angel; School of Engineering and Sciences; Campus Monterrey; Vázquez Lepe, Elisa VirginiaIn this work, metal powder bed fusion selective laser fusion (SLM) process was used for the fabrication of 3 different lattices structures because of its high resolution for complex geometries, there are plenty of research works in the parameter optimization for solid pieces, however, there is a lack of research for pieces with porosity and a micrometric scale where most of the measurements are not reported. To achieve this, different lattice geometries such as cubic, diamond and fluorite were manufactured, these were produced with different parameters, mainly varying the laser power, the scanning speed or exposure time, and scanning strategy using Surface Response Methodology to optimize the results. The struts from each lattice were measured in the Z and X axis, as well as the porosity of each piece. Additionally, compression test was performed to obtain the stress from the diamond a flourite lattice structure. The results are the parameters to manufacture pieces in micrometric scale for Renishaw AM400 with Stainless Steel 316L with a reduced dimensional difference from the CAD.
