kazmin Posted October 18, 2017 Share Posted October 18, 2017 Hi guys! I've been trying to build panels with backlighting like this one: http://kazey.flitepal.com/cockpit_build/backlit_panels/20170524_222631mod.jpg While researching, I came across videos and some topics: https://aviation.stackexchange.com/questions/2608/how-are-backlit-aircraft-panels-for-simulators-made https://www.youtube.com/watch?v=J5efmnMKkMs https://www.youtube.com/watch?v=UIGPb0ko0qE https://www.youtube.com/watch?v=9g2ipxu-VgM https://www.youtube.com/watch?v=vf7tQNYqliw Those topics and videos refer to some sort of "laser color", "opaque special white laser color" etc., which is something I cannot understand very well. It sounds to me that they are using a special paint that laser doesn't burn. What I got from the building process, is that it starts with clear acrylic, then this special white is applied, then black layer to stop backlighting, and then the final color. Then they go with the laser to achieve high contrast lettering. What I've tried so far, is getting opal white acrylic, figuring that when I paint it, and then remove the paint, I would get high contrast white. Yes, but no. This is my try: http://kazey.flitepal.com/cockpit_build/backlit_panels/wiper_2.jpg This has been painted black, and then with gray-blueish color, then laser engraved. The laser seems to burn the paint and leaves the acrylic with with some grayish shadowy color. Not what I desire to achieve. I did not apply white, because a) I am using opal acrylic and b) I am afraid the result will be the same. However, once backlit, it looks okay: http://kazey.flitepal.com/cockpit_build/backlit_panels/22641966_10214242823895493_1532820798_o.jpg But I want high contrast white when not backlit. Does anyone have the secret? Regards, Ivan Link to comment Share on other sites More sharing options...
coconutair Posted November 1, 2017 Share Posted November 1, 2017 What laser are you using? Wattage? Power settings? Speed? Pulse setting? Is laser accurately focused on paint surface? Not unusual for first pass to look a little "dirty". A second pass usually cleans up the text. Link to comment Share on other sites More sharing options...
kazmin Posted November 5, 2017 Author Share Posted November 5, 2017 Can you suggest settings? Also, can you mark with both fiber and CO2 laser? Link to comment Share on other sites More sharing options...
