Problem
Additive manufacturing systems face challenges in accurately replicating objects with varying physical properties across different areas, requiring complex input parameters and high technical expertise, making it difficult for lay users to efficiently manufacture accurate replica objects with anisotropic properties.
Innovation Solution
A method that generates a three-dimensional representation of a target object using domain values such as point clouds, curves, splines, vector fields, and texture maps to describe anisotropic behavior, allowing for the propagation of bodies with optimized parameters to match the object's physical properties, and instructs additive manufacturing systems to produce objects based on this representation.

Engineering Contradiction Analysis
1Manufacturing precision
If complex input parameters and calculations are used to accurately represent target objects, then manufacturing precision is improved, but device complexity and ease of operation deteriorate
Solution Approach 1:
The patent uses texture maps as simplified digital copies that encode physical property information. Instead of requiring users to input complex physical parameters directly, the system copies the appearance and texture information from reference images, which are then automatically processed to generate the required manufacturing data for accurate physical property replication.
Solution Approach 2:
The patent introduces texture maps as an intermediary between the user and the complex manufacturing parameters. Users provide simple texture map inputs rather than complex physical property specifications, and the system automatically processes these maps through algorithms to generate the detailed manufacturing data needed for accurate physical property replication.
2Manufacturing precision
If complex input parameters and calculations are used to accurately represent target objects, then manufacturing precision is improved, but ease of operation deteriorates
Solution Approach 1:
The system copies visual texture information from reference images to represent physical properties. Users simply provide texture maps rather than complex physical parameter inputs, making the system accessible to users without specialized knowledge while maintaining manufacturing precision through automated processing of these simplified inputs.
3Manufacturing precision
If individual areas are printed separately to achieve varying physical properties, then manufacturing precision is improved, but productivity deteriorates
Solution Approach 1:
The patent applies local quality by using texture maps that encode spatially varying physical properties across different regions of the object. Each area's physical characteristics are defined locally within the texture map, allowing the system to print the entire object in a single operation while maintaining accurate varying physical properties throughout different regions.
Solution Approach 2:
The patent merges multiple individual area print operations into a single printing process. By encoding all the physical property information for different areas within unified texture maps and using automated path generation, the system combines what would have been separate printing operations into one efficient process that maintains manufacturing precision.
4Ease of operation
If simplified input methods are used, then ease of operation is improved, but manufacturing precision deteriorates
Solution Approach 1:
The patent replaces complex manual parameter input with automated image processing algorithms. Texture maps are automatically processed through computational algorithms that extract physical property information and generate manufacturing data, substituting manual mechanical input with automated computational processing to maintain precision while simplifying user interaction.
Solution Approach 2:
The system uses texture maps as simplified inputs that are automatically copied and processed. The texture map information is copied into the manufacturing data generation process, where automated algorithms extract and apply the physical property information, maintaining manufacturing precision without requiring users to directly input complex parameters.
5Ease of operation
If texture maps are used to define physical properties, then ease of operation is improved, but difficulty of detecting and measuring deteriorates
Solution Approach 1:
The patent replaces manual parameter specification with automated texture map processing. The system uses computational algorithms to automatically analyze texture maps and extract physical property information, substituting complex manual measurement and parameter detection with automated image processing and data extraction routines.
