does acetone dissolve pla This is a topic that many people are looking for. bluevelvetrestaurant.com is a channel providing useful information about learning, life, digital marketing and online courses …. it will help you have an overview and solid multi-faceted knowledge . Today, bluevelvetrestaurant.com would like to introduce to you Does Acetone also work for welding and smoothing PLA 3D printed parts?. Following along are instructions in the video below:
” s up every. One tom here and at this point. It can be considered pretty pretty nmuch. Common knowledge that you can smooth out the layer lines of 3d printed made nfrom abs hips and delikes with an acetone vapor bath.
But i was told that this should also work non some type of pla like the ones from dasfilament. I was intrigued because the common understanding nis that pla shouldn t be affected by acetone at all. But i mean i ve got plenty of pla printed nparts laying around so why not just try it out so. Acetone is actually pretty cheap to get nhold of this 1 liter.
Bottle. Cost me just 299. And ni use it liberally for things. Like cleaning paint stripping and anything that s similar nto that as a first step just to try and see if acetone nhad any effect on pla at all i decided just to dunk.
A piece in the acetone liquid and nafter leaving it in there for a few seconds. It started to get really sticky and gewy on nthe surface and you could feel that layer coming off when you are rubbing it with your nfingers parts that are dunked in acetone like this nfor. An extended amount of time do get smoothed out. But they do loose a lot of their stiffness nand.
I also think they loose a lot of strength so that not really recommended. But it got nme thinking before we even get in to the acetone vapor smoothing part. I wanted to try out if nwe could actually solvent weld..
Two parts of pla. Together. Essentially the way you do that with abs or npla in this case is you take both sides brush some acetone on it let it dissolve just the nsurface and the press those two parts. Together it should get tack and sticky right away nbut.
It takes a few minutes or hours depending on how much acetone you put on there and how nbig the surface is to reach its full final strength. So i tried exactly that with two nclean surfaces of pla. Pressed them together and while it was clear that they were immediately nsticking together. I just set them aside for now for the vapor smoothing.
I m going to use the ntissues in the bucket method. This is not a method. I came up with i picked this up from nsomeone else and essentially what you do to get a very thick and consistent acetone vapor nis you take a few pieces of tissue paper use magnets to snap them to the inside of an old npaint bucket and then soak those tissues with acetone. If you want you can use some heat to speed nup the acetone evaporation.
But in general that is not really needed if you get the bottle na good shake beforehand and turn it around a bit since what you dunk into the vapor bath nis. Going to have a dissolved and ideally a liquid surface to it you need some sort of ncarrier to lift it out once your smoothing process is done. I decided to just use this nangle bracket put the benchy on there dunked it in and pulled it out after about 30 seconds. Nor so at that pont.
It was clear that the acetone was doing something the part felt nsoft and squishy on the surface. But there wasn t any noticable smoothing going on nthe one thing. I did notce was that the surface was getting a bit dull..
But that was about nit. So i gave the bucket a good heatup again refilled some acetone and set the timer to nfive minutes. Put the benchy back into the bucket and waited it out after five minutes. Nit was obvious that the effect was a bit stronger that with the shorter test.
But other than na softer and even less glossy surface. There wasn t really any smootging going on yet so ni decided to dunk. This part in and just leave it for about an hour now while that is soaking nin. Let s check back on the acetone welded.
Pla. Parts. And see if we can seperate them nand by the feels of it these have really bonded well even hammering a screwdriver between nthe. Two parts didn t seperate them the screwdrived did deform the parts.
But they didn t come napart in this case. I d say these are very properley welded. Together. There were no extra nadhesive used there was no super glue or epoxy or anything else involved.
There was just two nnatural non sanded. Even pla surfaces. Now let s check back on the vapor..
Smooth. Zoid buddah nthis print has been in the acetone vapor for a good hour or more and still it dose. N t look nlike. The acetone vapor.
Really did smooth anything out yes. The part is slowley becoming softer nand more squichey. But there is not a lot of melting and smooting going on so i guess if nyou would really submerge you parts in actual liquid acetone and the smere it around with nyour fingers. That could work.
But acetone vapor smoothing for pla is prittey much busted at nthis point. And just to cross check. If the acetone bucket was even working at all i took na part printed from regular abs dunked that in there for twenty seconds pulled it out nand boom. Perfectley smooth.
I mean just look at that isn t that an attracktive look for nthe. Most part. The trick was the vapor smooting abs was not to leave the parts in there for nto long just let him soak. But to give it quick dunkes in a highley consentrated acetone vapor nthat way you only dissolve the surface and don t get the entire part muchy.
But that in ndetail is a topic for another video. This video is sponsored by alephobjects inc. A free sofrware nlibre..
Innovasion. And an open source hardware company headquarted in loveland colorado usa nand makers of lulzbot 3d printers watch my review of both lulzbot 3d printers here and ncheck the links in the video description for more info on these machines straight from nalephobjects. So okey while acetone dose. N t really do much for pla.
When it comes to vapor nsmoothing. Other than maybe making the surface. A bit reflective. It does work perfectley for nwelding two pla parts together witch.
I didn t expect honestley so i hope you learned something ntoday aswell. If you did leave this video. A like subscribe and maybe even consider this nchannel with a monthley pledge over on patreon altso. If you want to buy some acetone you ncan acually.
Do that on amazon. The affiliate links that are in video. Description. Below nthat s it for today thanks for watching.
