"PPE" Topic

What masks are people using for resin printing?

You will get answers from: "I don't wear a mask" to "Resin is so toxic, I would never bring it in my house". So use common sense for you. If you are sensitive to smells/chemicals/etc, you will need to obviously take that into consideration. If you don't, simple ventilation to the outside and a cheap disposable mask will do.

I'm planning on getting a resin printer later this year. I plan on getting one with an air filter, and running it in the garage. I don't think I'll need a mask, but I'm to done with the plan yet. While the stuff can cause skin irritation I don't think under normal conditions you can breath enough to cause a problem.

I will wear gloves.

I know a guy who's been resin printing for years on a large scale, multiple printers, runs every day. He doesn't use a mask or even gloves and has had no problems so far. I wouldn't do that, but he's okay.

If you do want to wear a mask I'm not sure our trusty N95 or KN95 will do the job. You might need a proper respirator. You'd have to figure out what you actually want to filter.

Respirator with carbon filter. I use one for rattle can spraying

But I don't know anyone who uses a mask for 3d printing

I wear gloves because my skin does get irritated slightly. Anyway, from an MSDS

Personal protective equipment:
Respiratory protection:If this material is handled at elevated temperature or under mist forming conditions, NIOSH/MSHA approved respiratory protection equipment should be used.

Hand protection:Chemical-resistant gloves should be wore when handing this product.

Eye protection:Chemical splash goggles and /or face shield must be worn when possibility exists for eye contact due to splashing or spraying liquid, airborne particles, or vapor. Contact lenses should not be worn

Skin and body protection:
Depending on the conditions of use, protective gloves, apron, boots, head and face protection should be worn. This equipment should be cleaned thoroughly after each use.

2+ years into 3D resin printing. I don't wear a mask.

I bought one, but it's a PITA. The disclaimer is, I use eco-resin in a well ventilated (holes in the roof!) garage, and I'm rarely there when the printer is running, so it's just about setting it up, topping it up, and clearing back when it's finished.

I do use neoprene gloves – another skin condition I'm afraid – so I'm not prepared to risk direct contact, whatever the pundits say.

I have a very limited sense of smell, and to date have noted nothing. That is – of course – no indicator of safety: I haven't sniffed the resin bottle either, because I'm not an idiot ;).

If you are not a "crash-and-bash" merchant, you won't need the full hazmat suit, just a little care and attention, and an awareness of the potential issues.
