Mouse I printed on my Photon mono 4K. SLA is a learning curve for sure! I had LOTS of failures trying to print this.

    Once UV resin is cured and cleaned properly its perfectly safe to touch. It is a huge pain to work with in liquid state tho. Gotta wear gloves, mask, and eye protection. I have a wash station filled with alcohol that cleans my prints and a curing station.

      So in theory once it’s cured and cleaned it’s solid but the reality is we don’t really know that to be true. And my concern here is this isn’t something you might pick up now and again. This is something you’ll be in contact with hours at a time. Sweat and oil mixing into it.

      The best evidence I have on this is the fact that transparent resins often, if not sealed in a UV blocking clear coat, turn yellow. And traditional resins if not similarly sealed or sealed in an opaque layer (primer and paint) will crack if left exposed to UV light. That tells me the chemical reaction can continue and that they aren’t as inert as say the resins used in wood turning that have a chemical catalyst.

      Just want folks to be safe! But I’m betting you know the risks better than most.

        What can I say, I like to live on the edge! I wet sanded it after it was fully cured if that makes you feel any better. In all seriousness, I respect your comment in terms safety information. I just feel like being near someone using household cleaner or some second hand smoke would be worse for your health than this mouse. The liquid resin smells horrendous, once cured it does not smell or feel sticky or anything like that.

        Hear it from me, uv resin is nasty stuff in liquid form.

        It’s the first thing I tell people who ask me about getting into SLA printing. SLA may not be for you if you are not ok with wearing PPE and printing in a garage or well ventilated space. It’s alright when the printer is sealed and printing, but prep and clean up is a removed.

          Yeah I need to get my Saturn 2 up and running again. Just haven’t had time. I keep it in the garage but there isn’t any ventilation in there. I ordered the new stand alone Elegoo carbon filter but it won’t arrive until august. Been considering cutting a hole in a wall and adding active ventilation.

      In theory yes, but in practice it may not be. It’s all about personal risk tolerance. If you have higher tolerance you can ignore the possibility of health issues. Let people decide for themselves.
