Elegoo Water Washable Resin Review - Elegoo Mars

[@SaschaUncia]

I want to make a note about washing since nobody is talking about this. My first print was a large skull, it failed due to not enough resin in the vat so I did break tests with the printed 3/4. After a short wash and some curing it held up remarkably well for resin, surviving being thrown to the ceiling and landing on my Linoleum kitchen floor without damage several times. Then later I noticed most of my finished prints were very brittle, one of them crumbling with little force after curing and being limp and squishable before final cure. I did some thorough testing and long story short, do not leave the resin in a water bath for more than 2-3 minutes, after 5 in the ultrasonic it is markedly weaker and after 40 the cured print crumbles like a cookie. I'm not sure if it is absorbing water/minerals or if something is leaching out, but overwash and you will be sad. Washed briefly and the resin is surprisingly strong. I also tested air cure vs water cure, and while the water cured resin was slightly softer/more-brittle (most noticeably in thin supports), the difference was nowhere near as much as 3 vs 25 min cleaning. It looks like the resin is most vulnerable in it's half cured state right off the printer, if your UV oven is strong enough to cure prints quickly, you can probably still use a water bath if you want.

[@SuperReneeeee]

Thanks for the comment! I am trying to figure out why my print breaks of the build plate(after washing) I don't have this problem with the water wash from anycubic.

[@SaschaUncia]

@@SuperReneeeee I've tried a couple of brands of water washable and even had fully painted gifts break over a year later. Prints will be fine until heat and humidity hit them, then they crack like arid soil. Avoid water washable.

[@youtubevanced4900]

You should be using the basket insert in your ultrasonic. The idea is that the water or cleaning fluid is being vibrated and the model is not. the interaction between them creates the cleaning action and bubbles around the still model. If the model is sitting on the bottom and also vibrating the difference between the water and the model will be less and it will result in less effective cleaning.

[@kenshoning7532]

Uncle Jessy, what resin do you recommend for gaming miniatures that is durable and not brittle? Maybe you should make a video about Water washable, Plant Based, and Rigid + Flex resins and which is best for printing miniatures.

Not cleaning in the sink seems quite a good idea, but how do you clear the water you used before getting rid of it? Can you use UVs to make the residue solidify then filter it? Also interested in the durability compared to classic resin.

[@JackJonesTheButcher]

I pour my waste water into a clear tub with a clear lid. I then stand my UV light on top of it for 5-10 minutes, then strain the liquid and throw away all the hardened resin. The remaining water should then be OK to pour away in the drain.

[@knightsljx]

water washable resin is the future. with more R&D, the current weakness (literally) of water rein can be overcome. but the advantage of not having to deal with (use of and disposal) massive volumes of flammable solvents cannot be overstated

[@robbert2308]

The up side of using IPA is that it evaporates very quickly. So when it's time to dispose of contaminated cleaning solution you can simply leave a container open for a few days and the alcohol will disappear. Leaving dry cured resin to be thrown away. When using water, would you not end up with sludge and/or volumes of contaminated

[@ZappyOh]

How does the resin's strength/elasticity etc. compare to PLA ?

[@scrubsrc4084]

Brittle by comparison

[@greedfox7842]

depends on the resin, the standard photoresin is harder but more brittle than pla, the ABS like resin is like ABS, there is a TPU-like resin, and you can even get PC-like clears. really you can compare standard resin to BPA-free water bottle material, like those Nalgene bottles. harder than strong.

To get rid of the waste, I heard the good with with IPA is that you can just leave it outside for the alcohol to evaporate and then you are just left out with residual hardened resin, that can be thrown out normally but what would be the waste disposal procedure with water ?

[@katanakid13]

Largely the same. Leave the container of water out on a bright day, let the resin harden and fall, filter and repeat until it's clear water. I leave in a pretty hot area, so it usually just take a day or two for it all to evaporate.

[@1leo2008]

How do you dispose of the water once you have washed the print? I am new and have not done a print yet on my Mars 4 DLP, thanks

[@pacificcoastminiatures]

I've been trying a few test printson my new Mars 3 with the Washable Resin - not bad so far (had one rook of the two I printed this morning fail to adhere to the build plate - could be I didn't have it levelled properly). Glad you mentioned about the brush - I completely missed that they included this in the box of resin and just found it on the bottom of the box!

[@sinformant]

I've mentioned this on another KZbinrs video on the elegoo mars. But chitubox doesn't let you know when a thumb drive is full. If there isn't enough space to store a sliced model, it will simply save up to the point the drive it full and you will end up with a model that prints till the sliced layers end and the printer will just freeze at that level. I was lrinting something solid that was a 12 hour print. About 6 hours in it just froze up. I was asleep while printing and woke up to a failed print. Cleared it off the build plate and just started it again to come back and find the same result. It wasn't till I decided to reslice the model that I discovered the drive was full.

[@leafjerky]

this is so good to know thank you

[@BenjWarrant]

[@PortalPowerTV]

So where / how are you suppose to dispose of the resin infected water you use to clean the prints?

[@artspam]

I'd first reuse it like I would with IPA, and when it becomes really foggy I was thinking some old rags might work. Soak them with the used water, then put them out in the sun where they dry and cure the residual resin at the same time. (Edit) Reading Alpha Cat's comment, if you have a large enough water tight container to let the water evaporate that will be even better.

[@alphacat4927]

You should let the water cure in sunlight or UV light and then let it evaporate and then dispose of it the way you would other resins.

[@MattWeber]

Drop the water in the sun in a container.. the resin doesn't go into a solution as it does with alcohol, so it can cure solid in the sun and settles to the bottom. Then you can just take that solid chunk and throw it away, reuse the water since it wont take as long for the resin to cure vs waiting for water to evaporate.

[@renaissanceman8424]

I've been enjoying the ESun eResin-PLA and love it because it's really durable (PLA-like properties), such that I can throw models across the room without damaging them (don't do this kids! ;) ). The eResin-PLA is supposed to be safer (not totally safe still), with very little fumes (still ventilate), and is a step in the right direction as far as both material properties and toxicity.

You place it in a container then leave it somewhere safe so it evaporates. It'd be best in a place where there is direct sunlight so the water evaporates quickly and the left over resin is cured.

[@ackthbbft]

So, what IS the proper disposal method for used resin and resin-runoff from washing the prints? Do you keep a barrel of the liquid that you have Waste Management pick up? Hazardous waste fees? There are so many videos about how great the prints are, but I haven't seen anyone talk about the externalities of resin printing that we have to deal with.

[@zemerick]

It varies a lot on locality is one of the reasons. So, the proper disposal method in general, is "check with your local waste management office for the proper disposal method." The simple, though not entirely correct, answer though is just treat it like you would other plastic / cleaner waste. ( Note, you can cure out the bulk of the resin in the cleaner, then reuse it for quite awhile. )

I'm looking at getting my first resin printer. Primarily for tabletop and wargaming miniatures. Can someone tell me why you would want to clean out your vat between prints? Can't you just start a new print with the same resin?

[@jondoe230]

Yes and no. Always the chance of something getting printed wrong and falling off into the tank. Then not catching it when you take your minis off. It could then damage the machine or cause miss prints. But with that being said in just my experience I go right to printing another model. I always check to see if I had any fails. And if I do then I'll strain it back into the bottle and clean out my tank. Or just make sure I take anything out that failed and feel around in the tank with gloved fingers. If I feel like I missed anything I will clean the tank. Though more often its right back to printing, no cleaning. Use best judgement when doing it. Also if your not going to be printing anything out for a day or two strain the resin back into the bottle. Don't just let it sit inside the vat. I'd also recommend getting rubber dishwashing gloves instead of buying boxes of latex gloves. And get a large silicon mat. It helps with not making a mess on surfaces and you can rest your build plate on it while taking off prints. I've only used water washable resin and love it. I mostly print out wargame and table top miniatures and a few larger things every now and then. I hope you really enjoy getting into resin printing. Its so much fun.

Safety question here: how bad would it be to stay in the same well ventilated room as the printer. My printer is in the same room as my computer and I often work during printing. My window is open indeed and I wear a respirator and gloves each time I handle the resin, the printer, the vats or uncured prints. Thanks and great job!

[@infernaldaedra]

Depends on how well ventilated and if you notice any irritation or smell. Most of these printers are quite small so I doubt it will be any issue if the room is well ventilated

[@zemerick]

Some big questions would be: Do you have a fan for the window, where do you sit relative to the 2 ( such as if you are between the printer and window ), and how much actual printing you do. Basically, think of the printer as a smoker. ( Actually, cigarette smoke is probably worse...but that says more about how bad that actually is, and not much about the resin. ) If the printer is between you and the window, which has an exhaust fan, and you're only printing occasionally, you'll likely be fine. ( Note: Lots of health problems are probabilistic. You could always be the unlucky person that gets sick off of a very small exposure, while your next door neighbor practically swims in the stuff and is fine. Yay chance. )

[@MrDevilFlash]

@@zemerick Well, no exhausting fan on my window. The printer is around 2.5 meters in my back on the right (in a corner), my window around 1.5 meter on my right. I'm not disturbed by the smell and doesn't feel bad when it prints. Still use a respirator when I work on the printer or the print and make a full refresh of the air after a print.

[@zemerick]

@@MrDevilFlash Personally, I would get a box fan and use that to make sure the air flows from the printer, out of the window. Then, of course, keep on eye on yourself if you start to show any unusual symptoms, and adjust as needed. Disclaimer, I'm slightly on the less cautious side versus many. Others would certainly say you should not be in the same room as it during printing. Oh, it does matter what specific resin you use though. I haven't seen the MSDS for the water washable, but I would personally suspect it is a bit worse actually. The water washable means it is water soluble: IE, it would probably be absorbed by the mucus inside your respiratory system more easily, giving it a higher reaction rate. This is 100% guess though. Be aware that each different type of resin, even just different brands, can be dramatically different. The resins are currently a huge source of innovation, and are not at all standardized. So, 1 could be quite safe, while another highly toxic.

[@ChesuMori]

What exactly do you do with the support material? With PLA, I can just melt it down into sheets and store it away for random projects and/or to await the day that a decent product for turning it into filament hits the market... with ABS, I can dissolve it with acetone to make ABS glue. What do you do with resin supports, though?

Im new to this resin printing stuff and ill be getting my first printer and water washable resin this week, i understand you cant wash in the sink, so what do you all do with your water after you wash your prints? it kind of seems like a silly question but id like to know xD obviously not down the sink, obviously not drink... lol... do you just chuck it out into your yard?

[@petarknezovic9447]

If you use this resin can you do all the other cleanup work with water? Like the plate and places it drips.

[@raviswami9852]

Hi, Update on water washable resins - a couple of prints I made a few months ago started to liquify, which is not great, apart from the advantages mentioned in the video. Both items were thin sections or hollowed out and the chess piece test prints or smaller solid prints seem to be fine, but it would suggest that the material is inherently unstable and only of any real practical use for casting up in silicone rubber and then throwing away the prints afterwards.

[@raviswami9852]

I was using Elegoo water washable resin btw - other brands may be more stable.

[@LexxDesign3D]

Maybe you have a very humid environment

[@bubbadaluva191]

It's because there is still water or un curred Resin inside the hollow model. Need a pen uv light to get in there and cure it.

[@SEANANIGANS32]

Super awesome video, man! A lot of great information and the rant was A+++

[@UncleJessy]

Thanks man!!

[@tannerpayne6822]

Thanks for the videos. I got my Mars last week and water resin based on your videos.

[@Irish-Dog137]

Hey, haven't started with resin yet but want to soon. The one question I have is "After you clean the model, be it IPA or water, how do you do dispose of the used cleaning agent?" cant seem to find a clear answer on that.

[@slow-moe3518]

I think the safe way is to cure your container of IPA or water under UV light (so a clear one should work better), then strain it to discard the solids, then discard the liquid in the sink.

[@Irish-Dog137]

@@slow-moe3518 makes sense. thanks

[@zemerick]

​@@slow-moe3518 Not quite. There will always be resin left in the cleaner, so you shouldn't really run it down the sink. Technically, if you do it rarely enough ( since you can reuse the cleaner for a long time ) and run a good amount of clean water with it to dilute it down, it'll be fine. However, this is more to do with "the poison is in the dose" versus it being a good idea. Andrew: To expand on things, most people have switch to all-purpose cleaners, as they are far less toxic than IPA, cheaper, and are just as good if not better. The green cleaners are the current gold standard, but I wouldn't be surprised if something else is better that just hasn't been tested. The current common choice is Simple Green. After cleaning, you cure the cleaner as well to get the bulk of the resin out, then reuse that cleaner. I have done a few dozen prints, and have yet to need to discard my cleaner.

[@mrarma123]

If you were to recommend one of the smaller resin printers which is reliable what one would it be

[@UncleJessy]

Elegoo Mars 2 pro might be my fav. It’s a little more expensive but it prints crazy fast and the screen will last you a long time. Another smaller option would be the Phrozen sonic Mini

[@mrarma123]

@@UncleJessy I have been looking at these for a while now. Also what do you think of the mono x I just brought one of those also as my photon X does alright

[@PulsefiredGaming]

First comment what? Uncle Jessy, if the resin printer masking lcd screen is a consumable, do you think the screens for large format resin printers will be harder to find than the photon/mars/epax screen?

[@zemerick]

How hard something in general is to find is really hard to answer, but they are basically always at least available at the same time as the launch of the printer. I remember looking into the screen for a large format that launched recently, and they provided it immediately. It was $100 vs. normal ones being about 30-40, and the Mars screen is 20. Sad thing is that screen is one of the main sources of the increased cost for large format, yet these new printers are like $1,500. Good news is Elegoo announced awhile ago that they are working on something bigger. Nothing specific yet, but hopefully they can get prices to drop again.

[@UncleJessy]

I'm hoping the cost continues to drop and it becomes much more afforable to replace when you need to

[@zemerick]

@@UncleJessy It certainly would be nice, but I'd much prefer the printer itself be more around $500. As is, you could replace a screen 10-20 times just to match the existing price of large format printers. Add in the lower detail, and the existing crop are kind of lackluster. I would love a bigger print volume, but it just isn't worth it yet IMO. Fingers crossed that it changes soon, and the way things have been moving I would be surprised if it didn't!

[@bigboomer1013]

I noticed that its probably not UV curable? O just got to use it and when I put it in a curing chamber, I noticed that it doesn't glow under the UV light. How exactly do you cure it after printing? I use the Anycubic photon printer.

[@bertkooijmans4769]

You cure it with uv 405nm but cyring times i dont know i think it depends on your uvs i use a naillamp so i do 4 min flip em over amd another 2 then check for wet looking parts. I do think it makes a difference if you dry your prints wet curing seems a bit spotty in my case at least

[@InWhoseOpinion]

Is that Ultrasonic cleaner large enough for MARS 2 Pro full size print? If so, what is the model number, if not, can you recommend one that is? Thanks

[@nicolasb8740]

I have a question :) wath the best settings for water washable resin ? exposure time etc.. I am lost really

[@Arrowhead80]

You said many times to don't wash them in the sink, but you didn't explain where to throw the water you use. If not in the sink then where? I have a sink in the basement I dont use, can I use that?

[@stefanolsson1895]

Just curious... what do u do with the water u have cleaned the resin with???

[@scifimodelshop]

Can you pour the water washed with bits of resin floating around into a clear bottle and hit it with UV light to cure then dispose

[@michaels3003]

Sci-Fi Model Shop, yes.

[@metalgearbas4]

You use 8s exposure time with this resin? Why if I might ask? Everywhere online I'm seeing around 3s exposure times.. Why 8? that would almost triple printtimes from what I have now, so is the difference in quality really that noticable?

[@TheeAthis]

Jessy, do you have a link to the resins properties? (Elongation, deformation, temp thresholds ect? )

[@zemerick]

From their amazon post: Material Properties : Curing wave-length: 405 nm Hardness: 79.0 D Shrinkage: 7.1 % Viscosity (25°): 552.0 mpa.s Liquid density: 1.100 g/cm³ Solid density: 1.184 g/cm³ Tensile strength: 23.4 Mpa Elongation at break: 14.2 % Shelf life: 1 year(see production date on the label)

[@UncleJessy]

@@zemerick Much appreciated!

[@zemerick]

@@UncleJessy NP. You're one of the people that pointed me in the direction of the Mars, so I'm glad to help out in any tiny ways I can, even if it's just saving a few seconds googling. Besides, with early tech that moves this fast, we all need to help each other as much as possible.

[@ryanbellyt]

@@zemerick how does that compare to normal resin?

[@joecromwell9397]

Do you think it would be a good idea to spill this on a working electric space heater and or store is near such?

[@Rick-p7w]

The jar is out of stock now lol. I wonder what the manufacturer must be thinking.

[@NikolaosKaltsogiannis]

How is the smell with this resin compared with regular resin?

[@monogramadikt5971]

if you dont pour it down the sink ? how are you disposing of the waste material created by the process ?

[@haydenspence7107]

so once I'm done cleaning with water in a container. How do I dispose of the water afterwards?

[@tristonm37]

old video I know.. but did you take it straight from water cleaning to curing, or did you let them dry first before curing?

[@PayamMontazamifinearts]

Can this resin work fine with other printers like Anycubic Photon M3?

[@lcandmrpcomputers]

I have been using water washable for months no problems so far (detail cracking etc)

[@benceszabo2286]

Thanks for the video What slicer do you use?

[@joshuasolt8416]

I'm on the verge of buying a resin printer and I hear everyone say DO NOT POUR DOWN THE SINK.... How do people safely dispose of used resin? Or do you usually end up reusing it and having little waste?

[@Pixelon_]

How do you dispose of the water you used to clean the resin of the print? thanks.

[@Sixus1Media]

Bought a 1liter bottle of this. Worked great through about two thirds of the bottle, then i think the reason went wonky and I've been a week of headaches trying to somet it out. Stuff is super rubbery in the latter attempts and sticks to everything

[@Streamcatcher]

Did you shake before every print?

[@Centurion3D]

Cannot find Elegooe water washable resin on Amazon.ca but they do have esun water washable resin for $60.15 CAD don't know if it is a good resin?

[@RCZM64]

Both completely disappeared from amazon.es the week before Christmas, and could only find from "external sellers". I have a 1/2L of Esun brand on the way, arriving by the end of january, to test.

[@marcoz6269]

Great review, just what I was looking for. But I do have one question regarding what you do with that water afterwards? Let it evaporate and then keep the residue etc?

[@brettcardon4552]

I take the container of water and leave it in the sun to cure for a few hours. Then I strain the water into the sink so the cured resin pieces can be thrown away.
