PLA VS ACETONE, ETHLYL ACETATE and METHYLENE CHLORIDE

[@RFC-3514]

3:06 - Note that methylene chloride can go through nitrile gloves (which is what you seem to be wearing). Use either butyl or neoprene gloves, or don't wear any gloves at all (it actually evaporates very quickly off your skin). Any gloves that are permeable to it will actually make it take longer to evaporate and increase the likelihood of skin burns / irritation.

[@Cloakfiend]

Its all good i dont use it at all anymore. Its too filthy.

[@iroll]

Even better, just never use methylene chloride indoors, because it's just not something you want to breathe. I used it a lot when I worked in a very well-equipped analytical chemistry lab. The only other place I've used it is as a VERY GOOD paint remover, and I do that outside and upwind. It's actually not the most dangerous solvent you can mess with, but there's really no reason to ever be breathing it.

[@andyspoo2]

Apparently Tetrahydrofuran (THF) or oxolane (which is used for cleaning pools) will dissolve PLA. You might want to consider experimenting with that.

[@Cloakfiend]

Id try some thf, but when the filament companies change thier pla formulas it ruins everything. Ultimaker filament used to smooth the best but after maufacturing issues the company making their filament changed the formula and it no longer smooths. Must have removed the pha? Colorfabb is my main choice now.

You punch the top with a medium flatblade screwdriver, then, with the flat side pointed up, pry the top out by leveraging against the top of the threads. It should pop out fairly easily. After that, the cap will be the seal. The seal is just for storage and transportation mishaps. Thanks for the video.

[@sergeantseven4240]

I use Methylene Chloride to fuse and smooth most of my prints, it works on PLA, PETG, and other materials really well. almost too well some times, I buy it in 1 gallon Jerry cans off of Ebay for relatively cheap, can't get it anywhere else. plus it is really strong stuff so it needs to be stored safely and used in a well ventilated area. I use a respirator too even when just pouring it. I use vapor smoothing most of the time, where I have a pool of it in the bottom of a can and the part hangs above it for a few minutes. it evaporates really fast so no need to heat it or anything.

[@Cloakfiend]

Sergeant Seven it evaporates REALLY fast. I bought some and after a few months without using it less than half the bottle remained! Poorly packaged. I still prefer acetone though. Will try vapour with methelyne.

[@sergeantseven4240]

Cloakfiend acetone doesn't do anything with most PLA or PETG. I know you said you are only using colorfab. But acetone won't do anything to most other filaments besides ABS.

That seal lid on acetone, place a flat screwdriver on top (corner down) and whack the back with a hammer, it will puncture it and go inside a little, then tilt the screwdriver down and it will pop out, dispose of it as it's no longer needed.

[@Cloakfiend]

Yep agreed!

[@statoilbensin2190]

I have used Ethyl acetate to clean airbrush, same with acetone it works great for lacquer and enamel paint. The chloride stuff sounds like its quite strong so I would not dare use it to clean my airbrush as it might damadge teflon seals.

[@Cloakfiend]

I use acetone and airbrush cleaner. Ethly acetate is a bit strong for me. Methylene chroride is filthy stuff stay well away.

[@blade5098]

Thanks for this, I had never heard of Methylene chloride but I will be giving this a go. I watched a video made by DIY perks last night on his method of treating abs with acetone that seems to be quite effective and easy. He creates a simple vapour chamber so you don't need to use as much solvent or sit there brushing dipping or spraying and produces a very even finish. As all these solvents produce vapour at room temperature I would assume the method is interchangeable with all three of these. The video is called "Simple way to make ultra-smooth 3D prints at home"

[@danlane9917]

Thanks for the video, Will multiple applications of acetone get a result as good as methylene chloride?

[@Cloakfiend]

I still think a 30sec dip of acetone is just as good. Methalene chroride will destroy your prints over time. Acetone wont if you dont over do it.

[@gustavotobon7042]

Hello, Love the video, can you tell me how to prevent resin from sticking to pla printed molds. Thank you

[@Cloakfiend]

I wouldn't use pla to make a mould. I'd use a normal silicon mold for that. I dont make many molds but used to make a lot. Then you spray in mold release and pour in the resin. It comes out easy. Not sure if mold release works with pla but I would defo not use pla for molds!

[@bitsurfer0101]

I would use an ice pick to poke the top of the acetone can then pry off the seal.

[@TriptonStudios]

Does the Methel cloride affect the strength and hardness of the print ? I want the silk rainbow fillament color to be retained but with gloss and no layer lines ?

[@Cloakfiend]

The Meth chloride dries out the part a lot. Id personally go for acetone. I heard you can remove the whiteness with a heat gun apparently. Im going to try it again this weekend. Its time for another acetone and pla video. Methelyne chloride is seriously nasty try not to use it. Acetone produces just as good result imo. They both handle well. But acetone is safe imo been using it a lot for years. As long as you dont come into contact with it too often you should be fine. And if you usr transparent pla pha filament your part shouldn't split if printed well!

[@TriptonStudios]

Excellent if acetone works just as well; I heard the part stays soft and flexible after the process. Also I use many highly toxic Chemicals often so no stranger to the hazards of that! If I can use acetone though it’s better since it’s cheap And I already have a ton laying around!

[@Cloakfiend]

@@TriptonStudios dont apply it with an airbrush. With small objects you can dip them for like 30-45seconds. Then leave them for 20mins for the acetone to absorb. After the surface is dry, polish it up with an old toothbrush so that they become shiny. They may go white in which case you can apparently use a heat gun gently to remove it. Ill see how that goes tomorrow....

[@Cloakfiend]

@@TriptonStudios Btw, the parts only remain soft for about an hour or so then become harder and slightly more brittle.

[@purplehayes5718]

Have you tried Methyl Ethyl Ketone, also known as MEK? The real stuff, not the new fake stuff.

[@BreydonsRC]

Not sure why you would spray these solvents on instead of just brushing it on. Does your mask have chemical filters in it? It looks like just a dust mask. The best thing I have found for smoothing PLA is UV resin. Just brush it on and hit with a UV flashlight for a few seconds. It sands easily then.

[@Cloakfiend]

Acetone is easiest snd quickest in my experience. But you need to use a pla blend for it to work.

[@BreydonsRC]

@@Cloakfiend Acetone doesn't do anything to some PLA's. In fact, none that I have tried it on. Which PLA's are you using?

[@Cloakfiend]

@@BreydonsRC i use colorfabb pla/pha. My faves are the transparent ones. But they all smooth as they are blends of pla.

@@Cloakfiend ok, that make sense then. The clear PLA's and ones that are a bit tanslucent are a lot different than the opaque. I haven't tried acetone on any translucent PLA's. I typically don't use them. But I do have one brand that is like that. It seems more like PET than PLA.

What happens if i mix them all in a single bottle and use that mixture?

[@Cloakfiend]

Lol go for it but merhylene chloride is too harsh over time. Acetone is less aggressive and so is ethyl acetate. They dry out too much and cause splits. Ill make a vid showing what they looks like years later.

[@Cloakfiend]

@@captain6198 for pla/pha filament. Which is pretty much all i use. Ive had models completely deteriorate overtime. As for methylene chloride good luck storing that. That stuff evaporates through plastic, unless my lid wasnt any good, but it wasnt leaking and stull evaporated. Maybe glass vials? Not sure, but the container I bought it in was almost empty in 3 months without me touching it from being full.

[@captain6198]

@@Cloakfiend I extracted my dcm into a glass jar and using with a brush, a mask with organic vapor cartridge is a must though. The ethyl acetate ill dispose as its ineffective even when dipped into it. Methylene is the right answer but must be carefully used in a well ventilated area with a mask. Dipping into like 10 15 seconds is enough.

" dripping is far more waistful", really really, no one is asking to use a hole bottle for a single model, how much chemical are you using for dipping?

For dipping you need to sacrifice a container and just keep reusing it until it evaporates. Most dramatic results mind you. Prone to cracking if overdone. Economical. Can be used to brush on as well.
