| dc.description.abstract | This master thesis explores the optimization of parameters in resin-based 3D printing to enhance mechanical and structural performance. The main problem was the development of residual stresses in the polymer resin during the 3D SLA printing and post-processing, which led to distortion and affection of the mechanical and structural performance of the printed parts. The study was conducted using the Taguchi method, a statistical approach for enhancing quality of products or processes. Specifically the research focused on print orientation, layer thickness, UV curing temperature, and UV curing time to achieve desired outcomes while minimizing distortion.
Results revealed that print orientation, particularly the vertical setting of 90° had the most significant influence on both the signal-to-noise ratio and flatness of the printed parts. Additionally, lower layer thickness, UV curing time and temperature contributed to a better SNR and surface flatness. These findings offer practical insights to improve the overall quality of printed parts through careful adjustment of these parameters.
The thesis also addresses the environmental and financial highlights related to resin-based 3D printing. With certain limitations and potential sources of error, the study contributes to the existing knowledge in the field of additive manufacturing and provides a foundation for further research and development. It is hoped that these findings will inspire future advancements in the field, leading to improved performance and functionality of 3D printed products.
