Comment on RepRap Pioneer Returns With a DIY 3D Printer That Hits Micro-Level Precision

Simply neutralize and toss the support out in the regular trash. The neutralized waster is pretty simple, just leave it out in the sun and wait for the water to evaporate and the acrylate to cure.

That’s not unique to water-based resin, though. You can leave the dirty alcohol out in the sun, and if you’re waiting for it to evaporate, that takes less time with alcohol than with water.

Alcohol costs money and the vapors are toxic. You can get cirrhosis from inhaling that.

Isopropyl alcohol is significantly less toxic than the vapours from the resin itself, even if it’s water-washable. It’s somewhat more poisonous than regular alcohol, so it’s not a good idea to actively drink it, but it’s safe to inhale in reasonable quantities and get on your skin (as long as you’ve not mixed it with printer resin), hence being the main ingredient in hand sanitiser and pre-injection swaps.
As for the cost, it’s inexpensive enough to balance with the cost saving from non-water-washable resin of comparable quality generally being a little cheaper. It’s not like you use a whole five-litre jug per print.

Its just differently toxic. Acrylate monomer can give you the joy of cancer or physical toxicity.

The thing about IPA is that if you smell it you’re getting a dose of it. That goes to your liver causing damage to it.

Yeah both things are bad news.
