Sorry had to downvote this video, I use water washable resin all the time, it works great. Your video description makes no sense, just because its not properly advertised doesn't mean water washable resin should not be a product. Secondly 3D printers are NOT a consumer product, these things are not found on shelves in Walmart. These are hobbyist and business machines, and I willing to bet that 95% of hobbyist know that water washable resin is not safe and that it's toxic. In fact the comment section in this video kind of proves my point. I think this is a mountain out of a mole hill type video, that could have just been a public service announcement video explaining proper disposal instructions, instead of a click bait feeling title, where like myself and so many other's thought this was gonna be a video based on the validity of the product itself....

Until I heard of water washable resin I pretty much thought that 3d resin printing was never going to be an option for me. The products itself is not to blame, stupid people are stupid people and you can't call a product bad just because people are going to be doing stupid things with it. Very short sighted.

I thank you for your comment. I just want to say that IPA or alcohol is not the only washing solution available. You do have to realise that the spec sheet for water washable resin is most of the time worse than most other resins in similar price regions.

@@tnh_group I think that is the way of niche interests. You are right the companies SHOULD do more education. But as with a lot of niche hobbies, the problem comes down to individual practitioners. Every hobbyist develops their own processes for disposal and safe handling where there should be proper standards. Those will come with time. As for other washing techniques... If it's not alcohol based washing it still requires chemicals + water. For instance water+simple green. So isn't it better to just use plain water and dispose responsibly?

I agree that the marketing is horrible. I was expecting you to tell me why the resin itself wasn't as good of a product compared to standard resins. I use water-based resins which lets me use a half-jug of mean-green to wash my parts for over 3 months in my wash and cure station before needing a change, then I have a small pickle jar of distilled water I use to both water-cure and final rinse my prints, again, I don't need to change that water for months. Nothing ends up down the drain and I recycle everything without having to waste IPA. My parts come out with great detail and very clean. When I'm done I clean my gloves by simply dipping my hand in my mean-green and rubbing my hands up and drying off the excess with a paper shop towel (which also gets hung up and reused over and over.) I'd say that's pretty economically considerate overall and my end product is solid. Maybe the marketing is deceptive or "bad" but I've gotten pretty good results from water-washable resin. From my experience, people getting into the hobby get advice from others, and it's our duty to educate the newer folks on best practices regardless of the product. The product is just a tool. Any tool can be bad or dangerous when mistreated. At least that's my take.

Thank you for your comment. Water Washable resin is more brittle than "normal" resin but whether that affects you or not is different from person to person.

I just personally think they could do a better job of telling you not to pour it down the drain.

@@tnh_group Also wenn du dich mit dem Thema nicht auseinander gesetzt hast, dann vllt lieber kein Video machen ^^ Es bietet viele Vorteile ohne die Nachteile. Ipa verliert an wirksamkeit da der Alkohol ja verdampft, das Wasser hingegen verdampft kaum und muss nicht in dem Sinne nachgekauft werden. Außerdem läuft man nicht Gefahr sich selbst zu vergiften oder in die Luft zu jagen. Wenn du einen Unfall mit dem Harz hattest und was abbekommen hast kannst du einfach duschen gehen und musst nicht in ipa baden xD Das Wasser musst du halt genau wie den ipa in die Sonne stellen. Ich weiß aber nicht wo der Eindruck herkommt es sei nicht toxisch.. man ändert schließlich nur das Reinigungsmittel, UV Harz bleibt UV Harz xD Ich denke auch nicht dass man das unbedingt besonders betonen muss, das sollte eigentlich klar sein. Resin printing ist kein Hobby das man auf die leichte Schulter nehmen sollte, aber das ist immer der Fall, egal welcher Drucker oder welches Harz verwendet wird.

Well for some beginners such as myself water washable is the only option cause of the lower odor , i have to use my printer in my room , witch is not ideal i admit and i am well aware of that ( i try to avoid staying in the room while printing and i wear a mask while i do and i ventilate often ) . The lower odor and less material involved make my printer be bearable for my parebts . I have no other remote place to put it , i looked into it and printing in normal resin or tough resins is a no go cause i don t have a ventilation or filter system for my printer and if i print with the window open (witch can only be opened or tilted since i live in Europe ) the ambient temperature drops drastically in winter and spring time . Once i get a dedicated place for the printer i ll try normal resins too but as for now i encountered no problem with water washable elegoo resin .

A few days back, I was watching a vid of someone who used an electric water purifier to distill isopropyl for reuse with resin. It's an interesting idea BUT they made no direct mention of the dangers of distilling alcohol (fire, detonation, inhalation -- though they do mention the fumes/smell briefly). Anyway, it should be much safer to distil water but I think, like distilling the alcohol, it will leave resin residue inside the distiller, so there's some clean up involved. Not sure if it's possible to make it easier to clean with maybe a silicon or teflon/PTFE lining -something that would need to be examined in depth. --- As for how I do things, I sit my alcohol on a window sill to cure the resin and run it through a coffee filter for reuse. I still end up with sludge at the bottom eventually, which is later put into a bucket to evaporate into a film.
