Continuous Fiber Energy Monitoring in Composite 3D Printing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing additive manufacturing systems lack effective control mechanisms to monitor and manage the energy levels of continuous fibers during the manufacturing process, leading to potential disruptions and defects in the final structure.
Innovation Solution
The system incorporates a processor configured to execute computer-executable instructions that monitor the energy level of continuous fibers during discharge, determine if the fiber has lost continuity based on a reduction in energy level, and selectively interrupt the discharging process accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If continuous fibers are embedded within material discharging from the print head to multiply structure strength, then the strength of the final structure is improved, but the complexity of monitoring and controlling fiber continuity during the process increases
Solution Approach 1:
The system employs energy level sensors to continuously monitor the continuous fiber during discharge from the print head. When the sensor detects an energy level reduction indicating fiber discontinuity, it provides feedback to the controller, which then interrupts the discharging process. This feedback mechanism ensures structural strength requirements are met while managing control complexity through automated monitoring.
2Manufacturing precision
If the system monitors energy level continuously during fiber discharge to detect discontinuity, then the manufacturing precision is improved, but the energy consumption and device complexity increase
Solution Approach 1:
Continuous energy level monitoring provides real-time feedback on fiber continuity during discharge. The sensor detects energy level reductions that indicate fiber discontinuity, enabling precise manufacturing control. The system balances energy consumption by only interrupting the process when discontinuity is detected, rather than continuously stopping and starting.
3Reliability
If the discharging process is selectively interrupted based on fiber continuity determination, then the reliability of the manufactured structure is improved, but the productivity decreases due to process interruptions
Solution Approach 1:
The system selectively interrupts discharging only when energy level monitoring detects fiber discontinuity, maintaining structural reliability while minimizing unnecessary process interruptions. This feedback-based approach ensures that productivity is maintained at maximum speed during normal operation, with interruptions occurring only when quality issues are detected.

AI summary
A system is disclosed for use in additively manufacturing a structure. The system may include an additive manufacturing machine, a memory having computer-executable instructions stored thereon, and a processor. The processor may be configured to execute the computer-executable instructions to cause the additive manufacturing machine to discharge a path of composite material, including a continuous fiber and a matrix at least partially coating the continuous fiber. The processor may also be configured to execute the computer-executable instructions to monitor an energy level within the continuous fiber during discharging, to make a determination that the continuous fiber has lost continuity based on a reduction in the energy level, and to selectively interrupt the discharging based on the determination.
