Solution Overview

Problem

The aerospace and other industries face challenges in adopting additive manufacturing components due to inadequate quality control in supply chains, particularly for industries with stringent regulations, where vendors lack the resources and expertise to validate these components effectively.

Innovation Solution

An Additive Manufacturing Quality Management (AMQM) system that uses sensors to capture production data, compares it to a baseline profile, and generates quality control notifications for non-conforming components, allowing for remedial actions, thereby enhancing quality assurance without requiring vendors to perform extensive validation tests.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If vendors perform extensive validation tests on AM components, then quality control and reliability improve, but cost and time consumption increase significantly

Engineering Contradiction:
Improvequality controlVSAvoidvalidation time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system performs validation tests during the additive manufacturing production process itself, rather than after completion. Sensors capture process data in real-time and compare it against baseline profiles to identify deviations before the component is finished, enabling early detection of quality issues without requiring separate validation time

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system continuously monitors AM component fabrication by capturing sensor data during production, comparing it to baseline profiles, and providing real-time feedback on process deviations. This closed-loop feedback enables quality control without adding separate validation steps, as the monitoring occurs concurrently with manufacturing

Inventive Principle:
Principle #23Feedback

2Reliability

If vendors perform extensive validation tests on AM components, then quality control and reliability improve, but cost increases significantly

Engineering Contradiction:
Improvequality controlVSAvoidcost
Core Design Contradiction:
ReliabilityVSLoss of energy

Solution Approach 1:

The AM component fabrication system performs its own quality validation through integrated sensors and baseline profile comparison, eliminating the need for external validation resources. The system uses its own process data to validate component quality, making external validation capital and expertise unnecessary

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The sensor system serves multiple functions simultaneously: it monitors process parameters, validates component quality, and generates baseline profiles for future comparisons. This multi-functionality consolidates what would otherwise require separate validation equipment and expertise into a single integrated system

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Reliability

If comprehensive quality control measures are implemented in AM supply chains, then component integrity improves, but system complexity increases

Engineering Contradiction:
Improvecomponent integrityVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system creates digital baseline profiles that replicate the sensor data patterns of successfully manufactured components. These baseline copies serve as reference standards for validating future productions, eliminating the need for physical reference samples or complex validation protocols while maintaining high integrity standards

Inventive Principle:
Principle #26Copying

4Manufacturing precision

If real-time monitoring of AM processes is implemented, then manufacturing precision improves, but device complexity increases

Engineering Contradiction:
Improveprocess controlVSAvoidmonitoring system complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The system replaces complex mechanical measurement and inspection equipment with sensor-based monitoring that captures process data electronically. This substitution of mechanical systems with sensor/data-based systems achieves high manufacturing precision while reducing overall system complexity

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

AI summary

Additive Manufacturing Quality Management (AMQM) systems (10) and methods (60) are provided, which enhance quality control across Additive Manufacturing (AM) supply chains from which AM components are obtained. In various embodiments, the AMQM system includes an AM machine (20) utilized to produce AM components (40) in accordance with AM design data (34). A first sensor (42) is coupled to the AM machine and, during fabrication of AM components (40) by the AM machine (20), captures sensor readings pertaining to the AM fabrication process. When executed by a processor (44), computer-executable code causes the AMQM system to: (i) compile part-specific sensor profiles (110, 112, 114) from sensor readings captured by the first sensor (42) during fabrication of the AM components (40), and (ii) generate user notifications indicating whether remedial action should be performed for any of the AM components (40) based, at least in part, on conformance of the part-specific sensor profiles (110, 112, 114) with a baseline sensor (42) profile corresponding to the AM design data (34).
