Nozzle Clamp


One of the Daikin test chambers uses a nozzle to direct airflow into the chamber. However, the process to open and close the nozzle was a time-consuming part of the test procedure. Engineers designed a solution to attach a closing mechanism to the nozzle using a large clamp. This would reduce labor during test but the clamp was never manufactured due to the high cost of machining the large part from aluminum stock.
Hardware solution cost saving 93%


With the procurement of a large-format F770™ FDM® 3D printer, Daikin engineers printed the clamp as an alternative to machining. The F770’s large build chamber offered sufficient size to make the large part, providing an economical solution. The clamp was made using ASA thermoplastic and a hexagram infill for a strong but lightweight construction.


3D printing the clamp with the F770 gave Daikin the ability to permanently change the test procedure and speed up the test process, which has long-term benefits. Additionally, the 3D printed clamp was produced in hours and cost approximately $500 compared to $8000 to machine it from aluminum, a savings of 93%.
