Air Assist nozzle to fit chinese 15w diode laser etcher cutter
Description
This Fits Over The End Of The Typical Chinese Diode Lasers Which Are In The ~48Mm Square Housings (Eg. The 10 Or 15W Lasers). This Is For A Laser With A Fixed Focal Length Of Around ~18Mm. The Laser'S Cutting Was Improved Using Air, Less Burning On The Edges. I Have Used ~20Psi Which Seems To Work Well. For Hose I Used Some Surgical Tubing. In The Images Of The Cut Leather, It Would Have Worked Better If I Taped Down The Edges Because It Curled Up When Heated And Changed The Focal Length, But The Difference With And Without Air Assist Is Obvious. The Nozzle Is Easily Added And Removed, It Just Fits Over The Bottom And Can Be Held On With An Elastic. Its A First Prototype But Seems To Do The Job. This Is Only For The Fixed Focus Lasers, Not The Ones With The Adjustable Lens. It Does Not Interfere With Air Flow (From The Top Fan) Though The Aluminum Heat Sink, So The Laser Will Go Unaffected In That Respect. The Hose Should Be Able To Be Routed Across To The Back With The Wires, I Just Didnt Do That Yet
