IMPROVED ADDITIVE MANUFACTURING MONITORING METHOD AND SYSTEM - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240300184 titled 'IMPROVED ADDITIVE MANUFACTURING MONITORING METHOD AND SYSTEM
The present invention involves a method for non-destructively detecting deviating additive manufacturing (AM) process behavior of a 3D printed solid piece.
- Providing an impact to the solid piece, preferably a mechanical impact.
- Obtaining a vibrational response of the solid piece to the impact in the frequency domain.
- Extracting a set of eigenfrequencies, and optionally attenuations, from the vibrational response.
- Obtaining an eigenfrequency shift for at least one vibrational mode by comparing it to a reference eigenfrequency value, thereby detecting the deviating AM process behavior.
Potential Applications: - Quality control in additive manufacturing processes. - Monitoring structural integrity of 3D printed parts. - Identifying defects or inconsistencies in the manufacturing process.
Problems Solved: - Detecting deviations in additive manufacturing processes. - Ensuring the quality and reliability of 3D printed parts. - Preventing structural failures due to manufacturing defects.
Benefits: - Non-destructive testing method. - Early detection of process deviations. - Improved quality control in additive manufacturing.
Commercial Applications: Title: Non-Destructive Testing Method for Additive Manufacturing Quality Control Description: This technology can be used in industries such as aerospace, automotive, and healthcare for ensuring the quality and reliability of 3D printed parts, leading to safer and more efficient products in the market.
Questions about the technology: 1. How does this method compare to traditional quality control processes in additive manufacturing? - This method offers a non-destructive way to detect process deviations, providing early detection of issues without damaging the part. 2. What are the potential cost savings associated with implementing this technology in additive manufacturing processes? - By detecting issues early on, manufacturers can avoid costly rework or product failures, leading to significant cost savings in the long run.
Original Abstract Submitted
the present invention concerns a method for non-destructively detecting deviating additive manufacturing (am) process behaviour of a 3d printed solid piece, comprising the steps of: providing an impact to the solid piece, preferably a mechanical impact; obtaining a vibrational response of the solid piece to the impact in the frequency domain; extracting a set of eigenfrequencies, and optionally attenuations, from the vibrational response, each of said eigenfrequencies corresponding to a vibrational mode of said solid piece; obtaining for at least one vibrational mode: an eigenfrequency shift by comparing one of the set of extracted eigenfrequencies corresponding to said vibrational mode to a reference eigenfrequency value of said vibrational mode, thereby detecting the deviating am process behaviour.
