The use of coalescing and coalescence modifier agents, selectively applied to build materials, allows for controlled solidification and modification of material properties, enabling the generation of three-dimensional objects with specific properties by generating control data based on build material profiles, which includes parameters for agent distribution and energy application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If build materials and solidification methods are varied to achieve desired object properties, then manufacturing flexibility and object property customization are improved, but process stability and consistency deteriorate
Solution Approach 1:
The patent applies parameter changes by systematically varying build material compositions, agent concentrations, energy application parameters, and process conditions to achieve desired object properties. Build material profiles contain specific parameter ranges that when adjusted, enable customization of mechanical, thermal, and electrical properties while maintaining process control through defined parameter relationships.
Solution Approach 2:
The patent implements feedback mechanisms through build material profiles that capture optimal parameter settings and process outcomes. By analyzing build results and updating profiles with learned parameters, the system continuously improves process consistency. The profiles store feedback from successful builds that can be reused to maintain reliability across different manufacturing runs.
2Manufacturing precision
If careful calibration and recalibration are performed to ensure consistent output, then manufacturing precision is improved, but manufacturing time and operational complexity increase
Solution Approach 1:
The patent applies preliminary action by pre-calibrating and storing optimal build material profiles before actual manufacturing. These profiles contain pre-determined parameter settings, agent distribution patterns, and energy application configurations that have been validated in advance. When production begins, the system can directly apply these pre-calibrated profiles without requiring time-consuming calibration during manufacturing operations.
Solution Approach 2:
The patent uses copying by replicating successful build configurations through build material profiles. Once optimal parameters and process settings are determined for a specific object type, the profile is copied and reused for identical or similar manufacturing tasks. This eliminates the need to recalibrate for each production run, significantly reducing calibration time while maintaining manufacturing precision.
3Manufacturing precision
If build material profiles with detailed parameters are used to control the build process, then manufacturing precision and object property control are improved, but device complexity and data processing requirements increase
Solution Approach 1:
The patent applies universality by designing build material profiles that serve multiple functions simultaneously. Each profile not only stores geometric and material parameters but also encompasses process control settings, quality thresholds, and optimization rules. This multi-functional approach consolidates what would otherwise require separate systems into a unified profile structure, managing complexity while maintaining comprehensive control.
Solution Approach 2:
The patent uses composite materials metaphorically by combining multiple types of data and control parameters into integrated build material profiles. The profiles composite together material properties, process parameters, quality specifications, and optimization algorithms into a unified structure. This composite organization manages complexity by presenting a single integrated interface rather than requiring separate management of numerous discrete parameters.
4Manufacturing precision
If coalescing and coalescence modifier agents are selectively applied to control material properties, then object property precision and material performance are improved, but process complexity and number of processing steps increase
Solution Approach 1:
The patent applies local quality by selectively applying coalescing and coalescence modifier agents to specific regions of build materials based on desired object properties. Different areas receive different agent concentrations or types, enabling spatial variation of material properties within a single object. This localized control achieves precise property differentiation without requiring completely separate processing systems for each region.
Solution Approach 2:
The patent merges multiple agent application functions into a unified process controlled by build material profiles. The profiles integrate coalescing agent distribution, coalescence modifier application, timing, and energy parameters into a coordinated sequence. This merging consolidates what would otherwise be separate complex subsystems into an integrated process flow, reducing overall system complexity while maintaining precise material property control.

AI summary
Examples are described that generate control data (280) for production of a three-dimensional object. Build material profile data (260) is accessed for an indicated build material. The build material profile data for a given build material defines one or more parameter values that are dependent on the properties of the given build material and that are configured to generate a three-dimensional object with predefined build properties. Certain examples are arranged to generate control data for the production of a three-dimensional object by applying build material profile data to received object data (230).
