I tried this once and decided thhat it's too risky. Do not do this.

Rsein printers are not for bedrooms. You'll constantly smell that stuff and think that you're poisoning yourself. Also: spills will happen and you don't want that stuff spilled on your regular desk or on some object of daily use which then needs to be put out in the sun, just to be safe.

Chiming in to say that you absolutely don't want that in your bedroom. Not sure how ubiquitous the experience is, but if you're ever done a titration experiment in a chemistry class (the one where you add one solution into another a couple drops at a time), your body's response to being exposed to resin fumes (as well as VOC's from some of the more exotic fdm materials like ASA) is a lot like that: little by little you add more of one solution to the other and at first you don't really notice anything (beyond the volume increase), so you keep on adding more, when you finally hit the equilibrium point the whole solution suddenly changes colors.

In practical terms, the more you're exposed to resin VOC's the more you'll burn through your buffer, once it's gone your body will basically go into panic mode whenever it comes into contact with said material. It's one of those things that's high enough on the fuck around side of things that you really don't want to find out...

That said, welcome to 3D printing! There's plenty of resources around, so (for the most part) if you aren't sure about something or run into trouble, all you have to do is ask!

Yes, it really is that bad. We have a resin printer at work and it has been banished to a different room due to the resin fumes. The table it sits on is perpetually sticky, and we go through twice as much IPA postprocessing the prints than we use in resin

I have plenty of space, and I still sold off my resin printer because of fumes, mess, and general headaches. I don't recommend it if you aren't fully prepared for what it requires to do it safely and sanely.

I converted the closet to a 3D Printing area, adding a bathroom-style ceiling vent fan and shelf to hold the 3D printer, resin, cleaner and accessories.

I will tell you I can't smell anything with the doors shut, and the vent does a good job of removing the smell during printing.

Can't recommend TeachingTech's "Resin 3D printing beginners step by step guide" enough, that was basically the model I followed, including hanging paper towel holders on the inside doors and getting silicone mats to prevent spills.

Also, gloves. Every time. Every time I open that closet the first thing I do is put on gloves, even to touch the tools. I have no idea what still has resin on it, so I trust nothing in there.

Form 2 is challenging to operate for a newbie:

• laser -> "special" resin required. Formlabs recently moved on to LCDs meaning in the years to come the last third-party manufacturers will stop producing those resins as demand further declines. Leaving the first-party FormLabs as the only option ($100+/kg).
• Difficult to maintain resin tank. Requires a vacuum oven and an upfront investment of roughly $150 for chemicals. There are conversion kits/prints for FEP film to resolve this limitation.

It also isn't just the resin fumes that are toxic, but the post processing bio ethanol as well.

If you absolutely had to, print in your bathroom with the ceiling vent on. Otherwise, no.
