A fair bit of residue was left in the resin printer from last use. @3dtechs
Resin printer UV Exposure
That was me, sorry - how should I have removed that? Wash it with IPA? I didn’t want to rish scratching the FEP or having IPA seep where it shouldn’t go.
Happy to come around and clean up.
Thanks for reporting @nhjansen and for claiming @potatoman.
I cleaned it up. Any remaining resin that won’t go back into the bottle, just wipe down with a bit of blue towel and then finish with an another bit soaked in IPA.
Remember to cure any resin soaked rags.
Cheers!
Thank you for cleaning up after me. I owe you a beer (or any other drink of choice).
Can we get some UV protective glasses suitable for the UV torch please. The protective glasses we have are not for UV but for splashes.
We have an enclosed chamber ( curing area) for uv… I don’t see why we need uv protective glasses
Curing any spills…
If we have the UV torch, we should have UV PPE - i.e goggles
Not just spills. A UV torch is good for curing resin soaked blue paper. There’s a lot of that when one cleans up after printing. The curing station is great for printed models. It’s not good for curing resin soaked blue paper. The UV torch is much better. Having the torch is great, but we should have suitable safety glasses for that.
But if there’s a good technique for curing resin soaked blue paper in the curing station which makes it easy to do, it would be great to know.
Ok… But i always thought that the rule “don’t look directly to the light” was enough
The mention of a UV torch makes me, concerned? I’d like to know more about how the risks of such a tool would be operated and managed, not to as low as practicable but to as low as possible.
Was the torch bought by the space? Would be good to confirm its wavelength. If it’s 395nm which seems pretty common, a number of sources from a google would suggest it’s not harmful unless under consistent or prolonged exposure, i.e. you work with it daily.
That’s being said, no point in taking risks. We can get some glasses. Use the cure station whenever possible. Only use the torch in event of spills?
Ah should have measured it when I had a spectrometer at the space the other week! I would imagine it’s 365nm peak output which is middle of the uv-a band. @nhjansen I think the curing wavelength is listed on the resin bottles?
I read somewhere that WHO now recommend eye protection even to UV at 400nm.
I’ve had prolonged exposure to Southern Hemisphere UV rays and my eyes are nearing the point of developing cataracts. I’d prefer to avoid having eye surgery. Even if that weren’t so, it would still be best to spare eyes and use suitable goggles .
