METHOD FOR AUTOMATED 3D PRINT QUALITY ASSESSMENT AND REDESIGN

摘要

Shape diameter-based approaches to identifying and correcting 2D slices of 3D models (or the 3D models themselves) are provided for improved manufacturability. Using the present approaches, critical error-prone regions in 2D slices or 3D models can be identified, including thin extrusions and bridges, sharp corners, small holes, and narrow intrusions. The areas of these regions can be computed and used to quantify the printability of the slices or models. The boundaries of slices or models can be modeled as mass-spring-damper systems for performing local deformations to correct error-prone regions. External forces, that are a function of shape diameters and interior angles, can be imposed on the modeled systems for this purpose.
