Resins used in 3D printing are generally very absorbent to UV light due to the printing process using 405 nm light. They are many times peaks of absorption at 405 nm and around 350 nm. So if you use a light around 375 it would still get absorbed much less. Keep in mind that UV for long periods can degrade these resins.
Thanks for the information. Appreciate it :) About what degradation you are talkig about? Will it become blury or fragile? Cause it is really important. Also, do u think 20mW is the power that can cause visible degradation?
@@NickElectronicsthey’re probably talking about discoloration and visual artifacts along the plastic over time. The best way to fix it is to discolor the Resin ahead of time with blue or to expect it and make what’s inside the resin lacking the yellow that will occur over time. I don’t think u are using powerful enough uv to worry about it but after years of use or over a week of strong sunlight it will begin to discolor anyway as all resin does. I don’t know much about the mechanisms but I think the total boat website has information about it
@@NickElectronics I wouldn’t worry too much about it at this point. Like I said ur lights should be fine. I would wait till you start having a solid prototype to start worry about a protective finish or case. Plus any failures u make until then can be used as comparisons or test pieces when left out in the sun.
@ Yep, I see, thanks again. I am still thinking whether this design worth further attention or not. Cause I have lots of new ideas that I want to realize and no time for something doubtful 😅
Can you please avoid stupid titles like these? 'avoid this mistake' - its clickbait trash. Regarding UV and fluorescent paint - 365nm works best for excitation, keep using that, for duplicating/printing there is not much choice here - all good and bright paint are more or less ceramic in nature and the only suitable process is 'screen printing'.
@@VEC7ORlt Thank you for a suggestion, but It is too long for a youtube 😅I changed the title a little. I believe it fits the video better now. But you have to remember that youtube as a platform kinda pushes everyone to make a clickbait names and thumbnails. Otherwise it is hard to stand out
@@NickElectronics No one is special, and everyone is - in the end how do you even find anything meaningful if all titles are clickbait? How do I avoid this mistake I don't even know I'm making? Wait, that doesn't make any sense. Oh wait I'm not supposed to be searching - just watch this here and bitch in the comments, is that the face of YT these days?

@@cupidzsnakes6865 Thank you very much for the info. I will definitely take into account it next time I work on this design 👌

So cool😮
🤩 cool
Woooow! Amazing!

How would you call it then?
Be careful when using resin 3D printed part with UV light - the resin can absorb a lot of it.
Something like that.
