AI Technical Summary
Existing CAM-AM-SW products fail to effectively distinguish between important and unimportant dental angle areas when generating the support structure for dental restorations, resulting in compromised functional surface integrity and a large amount of post-processing work.
By detecting shear lines in the digital model of dental restorations and adding support structures along these shear lines, automated algorithms such as gradient methods, self-learning algorithms, and watershed methods are used to optimize the generation of support structures, ensuring the integrity of functional surfaces and reducing post-processing workload.
A stable additive manufacturing process has been achieved, ensuring the functional surface integrity of dental restorations while reducing the workload of post-processing.
