3D Object Policy Screening in Additive Manufacturing Workflows
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Additive manufacturing systems face challenges in identifying and managing 'objects of interest' during the 3D printing process, particularly in ensuring safety, legality, and compliance by modifying object models or delaying printing based on associated policies without disrupting the manufacturing workflow.
Innovation Solution
The system identifies objects of interest through object model data analysis and executes policy-based actions, which can modify the object model data, change the printing process, or delay printing, using a processor to apply policies that add identifiers, change resolutions, or alter the printing process based on predefined conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the system modifies object model data to add identifiers or change resolutions for objects of interest, then safety and compliance are improved, but the complexity of the manufacturing process increases
Solution Approach 1:
The system performs preliminary analysis of object model data before the additive manufacturing process begins. Objects of interest are identified and tagged with policy-based actions in advance, allowing the manufacturing system to automatically apply modifications without real-time intervention. This preliminary classification and tagging approach resolves the contradiction by establishing safety protocols beforehand rather than adding complexity during manufacturing.
Solution Approach 2:
The patent introduces an intermediary layer between the object model data and the manufacturing process. This intermediary system analyzes models, identifies objects of interest, and applies policy-based modifications automatically. The intermediary acts as a mediator that handles the complexity of safety compliance separately from the core manufacturing process, allowing both safety improvements and manufacturing simplicity to coexist.
2Reliability
If the system delays printing or modifies object models for objects of interest, then legal and safe production is ensured, but manufacturing productivity decreases
Solution Approach 1:
The system performs all necessary analysis, identification, and modification of objects of interest before the manufacturing process begins. By completing these compliance checks in advance, the system avoids delays during actual production. The preliminary action principle resolves the contradiction by ensuring legal and safe production through pre-manufacturing analysis while maintaining manufacturing throughput during the production phase.
3Reliability
If the system analyzes object model data to identify objects of interest, then compliance control is improved, but the time required for processing increases
Solution Approach 1:
The patent replaces manual or sequential analysis methods with automated computational analysis of object model data. The system uses computer-based algorithms to rapidly identify objects of interest and apply policy-based actions, substituting mechanical or human analysis processes with faster electronic processing. This resolves the contradiction by improving compliance control through automated analysis while minimizing the time required for processing.

AI summary
An example method for use in additive manufacturing comprises operating, by a processor, on object model data, the object model data describing an object to be generated in an additive manufacturing process. The example method comprises determining, by a processor, based on the object model data, whether a portion of the object to be generated is identified as an object of interest. In response to a determination that a portion of the object to be generated is identified as an object of interest, then the method comprises determining, by a processor, whether a policy-based action is associated with the object of interest. In response to a determination that a policy-based action is associated with the object of interest, then the method comprises executing, by a processor, the policy-based action, and generating, by a processor, the object according to the policy-based action.
