Hello Can anyone recommend a really good pair of UV Light safety Glasses to wear when Fusing parts together with ‘Raw’ Formlabs materials and a Laser pen? I need to ‘weld’ parts together. Help would be appreciated. All the best CHRIS ---

If you bought the laser from a legitimate supplier, it will meet the FDA requirements for energy level and you do not need safety glasses. How many milliwatts is the laser? ---

@BenKrasnow made a nice video about UV absorption eyewear: The last 4 minutes explain the optical density value, which is a rating used vor UV safety glasses. I think for welding parts you can also use a UV led torch instead of an UV laser pen. For that the “5$ Amazon” UV safety glasses should be enough. ---

[These are the glasses](https://lasersafetyindustries.com/450-nm-laser-safety-glasses/) I got. They’re OD6+ @ 190-532nm. ---

Good morning, I thank you for the replies, the Laser Pen I bought is a Laser 303 from China, wavelength 405mm Class III therefore I did not want to take any chances. I purchased some Welding glasses by Bolle Italy, Lens Polycarbonate, shade 5. From [SafetyGoggles.co.uk](http://SafetyGoggles.co.uk). I have to say they are brilliant, comfortable over my normal day wear glasses. I can see the detail I need to through them when welding, they have a quick neck strap as well to easily to keep handy. Thanks again All the best Chris ---

so why doesn’t formlabs - use the same green tank plastic on its printers rather than the orange if its soooo much better ---

Welding goggles are intended to block much higher levels of illumination than the FL printer generates. Also, light from welding is a broader spectrum than just 405nm. ---

I don’t know. My guess is that the orange material was used in the first formlabs products because it was available and already in use by the semiconductor industry. If you take a look at a semiconductor lab/cleanroom you can see alot of orange windows in the photoresist processing sections. For the newer formlabs products i think orange is chosen over the dark green material because it looks better and it became part of the iconic formlabs product design.
