1Productivity
If manual configuration is used to determine spatial relations between shells and attribute properties to volumetric regions, then the system can process 3D models, but the process becomes time-consuming and labor-intensive
Solution Approach 1:
The system automatically determines spatial relations between shells and attributes properties to volumetric regions without requiring manual user configuration. The processing system autonomously analyzes the 3D model data, identifies shell relationships, and assigns material properties based on the automated spatial analysis, thereby eliminating time-consuming manual intervention while maintaining processing accuracy
Solution Approach 2:
The patent replaces manual mechanical configuration processes with automated computational algorithms. Instead of manually determining spatial relations and attributing properties, the system uses computer processing to automatically analyze shell data, calculate volumetric overlaps, and assign material properties through software-based spatial relationship determination

3Adaptability or versatility
If multiple shells with different properties are processed, then the system can handle complex 3D models, but the complexity of determining spatial relations increases
Solution Approach 1:
The patent segments the 3D model into discrete shell elements, each with associated properties. By breaking down the complex model into manageable shell components that can be processed individually and then combined through automated spatial relationship analysis, the system handles complex multi-shell models systematically without overwhelming complexity

AI summary
A method for selection of a print head of a three-dimensional (3D) printer includes receiving a model data element having first and second 3D shells, producing an ordered set of slice data elements corresponding to a planar slice of the 3D model, determining an overlapping region of the first and second 3D shells, attributing a property vector value (such as a colorization vector value or a printing material vector value) based on an overlap rule, and selecting a printing head based on the property vector value. A 3D printing system comprises printing heads that can be selected according to the method.
