FUSED FILAMENT ADDITIVE MANUFACTURING INSTALLATION COMPRISING AN EXTRUSION NOZZLE AND A DEVICE FOR MEASURING AND THERMALLY CONTROLLING THE METHOD - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240278504 titled 'FUSED FILAMENT ADDITIVE MANUFACTURING INSTALLATION COMPRISING AN EXTRUSION NOZZLE AND A DEVICE FOR MEASURING AND THERMALLY CONTROLLING THE METHOD
The abstract describes a fused filament additive manufacturing installation that includes a thermographic device with thermal cameras linked to the frame of reference of the extrusion nozzle. The cameras are oriented around the extrusion axis of the nozzle and cover a zone surrounding the extrusion axis with overlapping fields of view.
- The installation records matrices of historical sequences of temperature and relative position of a point of reference of the nozzle with respect to the plate or print support for each thermal camera.
- The extrusion nozzle deposits a filament of material on a receiving surface supported by a mobile plate.
- The thermographic device helps monitor and control the temperature and position of the extrusion nozzle during the additive manufacturing process.
- The overlapping fields of view of the thermal cameras ensure comprehensive coverage of the printing area.
- The recorded data allows for precise tracking and adjustment of the extrusion process.
Potential Applications: - Additive manufacturing - Quality control in 3D printing processes - Research and development in materials science
Problems Solved: - Monitoring and controlling temperature and position in additive manufacturing - Ensuring accurate deposition of material in 3D printing
Benefits: - Improved printing accuracy and quality - Enhanced process control and efficiency - Potential for innovation in additive manufacturing technology
Commercial Applications: Title: Advanced Additive Manufacturing Quality Control System This technology could be used in industries such as aerospace, automotive, and medical devices for high-precision 3D printing applications. The system's ability to monitor and adjust the printing process in real-time can lead to cost savings and improved product quality.
Questions about the technology: 1. How does the thermographic device contribute to the efficiency of the additive manufacturing process? 2. What are the potential implications of using thermal cameras for quality control in 3D printing?
Original Abstract Submitted
a fused filament additive manufacturing installation comprises an extrusion nozzle for depositing a filament of material on a receiving surface supported by a plate that is mobile relative to the nozzle and a thermographic device. the thermographic device includes at least two thermal cameras linked to the frame of reference of the extrusion nozzle and oriented around the extrusion axis of the nozzle. the fields of view of the thermal cameras are determined so as to cover a zone surrounding the extrusion axis with an intermediate zone in which the fields of view overlap. the installation further includes a means whereby, for each of the thermal cameras, matrices of the historical sequences of temperature (x, y, z, t)and relative position (x, y, z)i or (r, �, �)of a point of reference of the nozzle with respect to the plate or print support are recorded.
