Powder Bed Fusion Component Identification for Property Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing powder bed fusion additive manufacturing (PBFAM) processes struggle to efficiently track and distinguish between identical components, leading to inefficiencies in recording manufacturing properties and potential loss of information, especially when large numbers are produced, making it difficult to optimize performance and quality.
Innovation Solution
Assigning a unique identifier to each component during the manufacturing process, which includes manufacturing properties, and integrating this information into a database for easy access and optimization, allowing for precise tracking and improvement of component performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If manual labeling is used to record manufacturing properties of each component, then component information can be tracked, but the process becomes inefficient and error-prone when large numbers of components are produced
Solution Approach 1:
The system enables self-service by automatically capturing manufacturing properties during the PBFAM process and embedding them with component identifiers. The PBFAM system itself generates and stores the data without requiring external manual intervention, making the system record information about itself autonomously.
Solution Approach 2:
Manufacturing properties are recorded in advance during the manufacturing process itself, before components are removed from the build volume. This preliminary recording ensures data is captured while still accessible and avoids the need for post-manufacturing data entry.
2Productivity
If components are produced in large batches to optimize productivity, then manufacturing efficiency improves, but the ability to track and distinguish individual component properties deteriorates
Solution Approach 1:
The system segments batch manufacturing data by assigning unique identifiers to each component and recording their specific manufacturing properties separately. This segmentation allows individual component tracking within batches, maintaining measurement precision while preserving batch production efficiency.
Solution Approach 2:
A database acts as an intermediary between the PBFAM system and component tracking requirements. It stores and manages the relationship between component identifiers and their manufacturing properties, enabling precise tracking of individual components even when produced in large batches.
3Productivity
If the nesting algorithm optimizes build volume utilization to maximize component output, then productivity increases, but information about component locations and manufacturing conditions may be lost
Solution Approach 1:
The system performs preliminary recording of component locations and manufacturing properties during the nesting and manufacturing process. By capturing this data in advance while components are still in the build volume, the system preserves location information that would otherwise be lost during post-processing removal.
Solution Approach 2:
The system implements feedback by continuously monitoring and recording manufacturing properties and component locations during the PBFAM process. This real-time data capture ensures that information about component positions and manufacturing conditions is preserved and can be used for future optimization.
