Sonochemistry (3) Ultrasonic Waves Never Stop Evolving (Removal of Residual Fine Powder in Metal AM Internal Microtubules)
AM metal printers and metal 3D laminated molding technology are spreading rapidly for aircraft parts, military parts, space equipment, and more. Miniaturization of parts, integration of many parts. Designs are complex and now often human- and AI-driven. More complex, and the ultimate miniaturization is also the goal.
There are problems. The smaller and more complex the design, the more metal particles are left inside. The nozzle of a multi-ton rocket engine must be completely cleaned of residual particles to ensure safe performance.
Correctly tuned ultrasonic waves penetrate the metal 3D AM with almost no attenuation. This helps to remove residual fines. The metal fines are pushed out through the 1 to 3 mm diameter tubes inside.
Bluestar R&D has begun selling in the U.S. market, which is 100 times larger than the Japanese AM market because of its small size.
