Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current additive manufacturing technologies face challenges in precisely generating three-dimensional objects with specific properties such as color, strength, conductivity, and density, as existing methods lack efficient data processing and material mapping techniques to achieve consistent and practical results.
Innovation Solution
The method involves defining a property gamut using n-dimensional vectors and convex hulls to map between property spaces, allowing for the determination of optimal print material combinations and application locations through halftoning techniques, ensuring that generated objects meet specified constraints and properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional additive manufacturing methods are used to generate three-dimensional objects, then the basic layer-by-layer construction can be achieved, but the precision and consistency of specific properties (color, strength, conductivity, density) cannot be controlled
Solution Approach 1:
The patent segments the property specification into discrete property parameter sets that can be independently defined and controlled. Each property (color, strength, conductivity, density) is broken down into measurable parameters that can be mapped to specific print material combinations, enabling precise control of each property dimension separately while maintaining overall object integrity.
Solution Approach 2:
The patent implements systematic parameter changes by establishing mapping relationships between property parameters and print material characteristics. By defining property gamuts with minimum and maximum values for each parameter and creating corresponding material combinations, the system can precisely adjust and control object properties through parameter transformation rather than trial-and-error manufacturing.
2Adaptability or versatility
If arbitrary property combinations are specified for three-dimensional objects, then design flexibility is improved, but the ability to achieve consistent and practical results deteriorates
Solution Approach 1:
The patent performs preliminary action by pre-defining property gamuts and mapping resources before the actual manufacturing process. Property parameter sets with minimum and maximum values are established in advance, along with corresponding print material descriptions. This preliminary configuration ensures that only practical and achievable property combinations are specified, filtering out impossible or inconsistent requirements before manufacturing begins.
Solution Approach 2:
The patent implements feedback mechanisms through the mapping resource that connects property parameters to actual print material characteristics. The system provides feedback by validating specified properties against predefined gamuts and mapping relationships, ensuring that desired properties are achievable with available materials. This feedback loop maintains reliability by preventing specification of impossible property combinations while preserving design flexibility within feasible boundaries.
3Ease of manufacture
If existing data processing methods are used in additive manufacturing, then basic object generation is possible, but the ability to map between property spaces and determine optimal material combinations is insufficient
Solution Approach 1:
The patent introduces mapping resources as an intermediary layer between property specifications and print material selection. The mapping resource contains property gamuts and parameter sets that mediate between desired object properties and actual material combinations. This intermediary structure simplifies the manufacturing process by automatically translating high-level property requirements into specific material instructions, improving both ease of manufacture and property control accuracy simultaneously.

AI summary
In an example, a method includes receiving, at a processor, a plurality of property parameter sets representing attainable property combinations in additive manufacturing and being associated with print material description. A constraint of a first property of the property parameter sets may also be received and a hull of a property mapping resource for use in determining additive manufacturing instructions for generating an object in which the first property meets the received constraint may be determined.
