Adaptive Layer Thickness for 3D Printing Precision

The patent applies different layer thicknesses to different regions of the 3D model based on local geometry requirements. Surface elements are classified into first regions (requiring thin layers for high precision) and second regions (tolerating thick layers). This local differentiation allows thin layers to be used only where geometrically necessary, while thick layers are used in regions where they suffice, thereby reducing total printing duration while maintaining required precision in critical areas.

The patent introduces a dynamic precision requirement parameter that can be selectively assigned to different surface elements. Instead of a fixed precision requirement throughout the model, the system allows the precision requirement to vary dynamically across different regions. This enables flexible adjustment where high precision is required in certain areas (first regions) while lower precision suffices in others (second regions), optimizing both printing duration and quality according to specific application needs.

The patent divides the 3D model into different regions with different precision requirements. First regions (such as spherical surfaces or areas requiring high geometric fidelity) are assigned thin layers and high precision requirements, while second regions (such as planar surfaces or areas where coarse approximation is acceptable) are assigned thick layers and lower precision requirements. This local quality differentiation maintains precision consistency only where necessary, while allowing productivity optimization in regions where high precision is not critical.
