[@ScytheNoire]

I worked in a University research lab and this is how the ultrasonic with can lead to combustion: As it vibrates it causes particles of the fluid to go into the air. This creates air that is now an explosive mixture of oxygen and a fuel. If that mixture of air comes in contact with a flame or spark, you will get an explosion. Part of the safety training, and lab rules, is to never run the ultrasonic with the lid off, as it will fumigate the area, and always run the ventilation hood, to remove the explosive gas when you open the ultrasonic cleaner. It really is no joke, it can happen, and it's extremely volatile gas mixture. Should only be used in well ventilated areas, should have a fume hood, always run with lid down, and DO NOT, under any circumstances, have any ignition source around while using. I would bet the companies instruction manual or documentation has such warnings, thus protecting the company from liability.

[@Desmo904]

Handy to know! Wow, cheers!

[@MarchLMAA]

Absolutely, lower explosive limit for IPA is 2%. Autoignition temp is high, true but irrelevant if you have this operating next to non-Ex equipment. Flash point is 12°C meaning if the concentration of IPA in the air is above 2% and it's not freezing you can have a really bad time in your hobby room. There are ultrasonic safe organic solvents though.

[@charlescarpenter9098]

I was actually coming to the comments to speculate this. My ultrasonic cleaner is a super cheap amazon buy (like

[@smtkelly]

I seem to remember reading a guide to these: The US army stated you can use ISO with an ultra sonic cleaner however ISO and the item you wish to clean should be in a closed bag (like a zip lock) and the ultra sonic cleaner should be filled with water. I used it that way because you need less ISO

[@ScytheNoire]

@@smtkelly That's an interesting way to do it, and much safer. Great idea.

[@Zeft_Dylis]

When I use it, I fill the tank with 5 liters of demineralized water and use a zip bag for freezer to put my prints in with IPA. I try to push all the air out of the zip bag. It works well and it's easier to manage the alcohol and not waste too much . After each session, I empty the tank using the drain and put the water back in the jar. With this technique there is less risk of combustion. For the UV device, I agree with you. I don't know why they choose to open it by the top ( maybe it's more ergonomic when you want to put prints inside) but the combo printer, ultra sonic and cure take a lot of space.

[@jarrettguma5522]

what do you do with the used IPA that's in the zip lock bag?

[@Zeft_Dylis]

@@jarrettguma5522 I put it in a recipient to reuse it for the next print if it IS clear enough or I use it for the first clean because I use a two baths method. First with used ipa to clean my print and remove the most of the resin and After the Sonic cleaner.

I am a recent new subscriber and amazed at the quality of your videos and content. You have lead me in the right direction, so much so I went with the Photon M7 Pro that you reviewed. But, it kills me you only have 65k subscribers, were gonna have to change that for sure. Thanks for the hard work, and keep us informed. I have never done KZbin join or Patreon but think you may have changed that also.

[@SgtHouse]

Great review as always! Please keep up the great work! Also I used a sonic cleaner once with the isopropyl alcohol and it's true. The explosion took out 30 square blocks leaving a huge mushroom cloud in its wake. Luckily, I survived as I was getting a drink, the blast pushed me into my lead lined refrigerator and ended up a few miles away. I was hurt, but safe. Hope this never happens to anyone!

[@CrazyAngelfire]

I agree with the cure station, i kinda wish it opened from the front. You could then put it on a shelf above the wash station and save desk space. That was my plan anyway

[@aberodriguez4149]

Great review and I agree with you on the efficiency of the Cure station as for the Wash station the area should be well ventilated when using IPA or other volatile liquid especially making it safe for family members.

[@Cilu27]

I was literally looking for a review of these items yesterday! Perfect timing :)

[@myriadworlds8434]

can we get a comparison on conventional resin vs water washable resin cleaning in this please?

[@MrShaneSunshine]

Tip....pour your bottles of spirits or washer fluid with the spout on top! 🎉

[@Iskelderon]

Interesting! I've been doing that for a while, but with water-washable resin and a used lab-type sonic cleaner.

[@markburton5292]

I have never had my small ultrasonic cleaner spontaneously combust with ISO 99 in it, even with the heating turned on (although I don't usually use it with heat on. I can set the temp on mine and i set it at 50c (122F) which is less than the boiling point (82c) of iso ). I tried it with heat on and heat off to see if I got any different results in cleaning and I can't see any difference as far as cleaning goes with the temperature I use. The advantage of heat is in drying after the cleaning. disadvantage is it puts more VOC into the air. but since its in a well ventilated area it isn't that big of a deal. however on the ultrasonic cleaner instruction they don't recommend using iso as it can vaporize. and then some external source could ignite it. That however is not spontaneous combustion. this is what they say. "Use water-based detergents. Solvent-based cleaners are generally not designed for use in an ultrasonic cleaner, and may damage the stainless tank surface in some instances. Solvents with low flash points - below 200˚F, are never recommended. Plus solvents are unhealthy for humans." "Never fill the tank of an ultrasonic cleaner with alcohol, gasoline, or any other flammable liquids. They will vaporize, and could cause a fire or explosion, or release harmful gasses into the workspace." However I use iso in mine on small parts with really fine details as I don't want them to get broken by swirling around in the other cleaner. as long as you take proper care its perfectly safe.

[@FauxHammer]

Yeah I read later its the fumes that can cause issue., but also heard Uniformation have lowered the power oif this to reduce fumes, not confirmed, just heard it in a comment

[@Chimer24-qs5wo]

Not quite sure how I managed to miss the video till now [old age perhaps]. Good review as always Ross )O(

[@johnhinkey5336]

I've had some resin manufacturers tell me via email that there is no such thing as over-curing in the typical UV curing chambers and thus there is no such thing as an optimum time. For engineering-like resins they are quoting an hour or two and even that length of time + 60C to get full strength. Maybe the cheaper resins have a maximum cure time .above which they degrade in properties . . .

[@HEMASimian]

This. There is the resin's final state and then there's being undercured. We've tested curing prints for days under heavy duty UV hoods and they weren't any more brittle than when cured 8+ minutes per side. Undercuring your prints to be more durable is a bad idea because it'll still off-gas, and will still be toxic to the touch. There are resins that existed out there too that literally change colour depending it reached that final state or not. So "overcuring" really is not a thing.

[@Desmo904]

Nice review of the pair. I have to agreed with you on the curing station. I DOES look like it should open frontward and the fact that the rather flimsy hinges are on the lid does make it look cheap. I'm a bit surprised at the rather large dimensions of the unit and the big sides which limit the volume of the curing station. That and the fact it's a top loader means entry and egress are all the more likely to drop prints and damage them compared to Elegoo where the entire lid comes off to allow open access to them. The washing station looks like a deep fat frier for chips! I'd be keen on an ultrasonic cleaner though. I do wonder at how well the drain pipe will keep clear and not clog up with used resin after a while.

[@demjot2967]

He didn’t mention it but there’s a foam sponge at the bottom of the cleaner to traps thicker liquids or tiny parts when you drain

[@benkonczal4584]

I have this whole set up and love it. But I did add a bunch of aluminum tape to the inside of the curing station. I’m thinking of adding mirrors… but I also haven’t had any problems with anything curing so…

[@TheRealOzWookiee]

Comment for the algorythm ;) Nice work mate. Love watching your videos.

[@the_kroete4357]

Wohoo i got it right. I happily dismiss the 12k upgrade but will surely grab the wifi dongle 😊

[@aberodriguez4149]

I was thinking also that after some time placing your vat on the ultra sonic cleaner this could possibly lead to your alignment screws backing out and thus throwing vat and screen tolerances off. I myself do not own a rein printer at this time but just thought I would drop my 2 cents in. XD

[@cgrosbeck]

This cleaner is made to explosion proof standards on the electrical side!!! Also flash point does not mean that the liquid or vapor will ignite, you still need an ignition point heat (temperature) flash point only means that instantaneous combustion can occur all at once you still need the ignition source!!!

[@FauxHammer]

thanks for the info

[@CookieManCookies]

I stand by mean green, the hand friendly version. All the other stuff I've seen are either corrosives, or flammables.

[@mtoveyx10]

I was looking to get the Uniformation GKTwo, from your recommendations and to know how the Wash and Cure works in relation to others will be helpful, I know you will say it wash's and Cure's but your opinion matters to me ;)

[@FauxHammer]

Sorry my opinion on these is that they all do the same thing. and as you suspected, they wash and cure. The only difference I;ve seen is size. personally I use the Phrozen for washing as a first stage, then the Uniformation one as a second stage. I use Heygears Station to cure becasue that one is the most industrial and mostly, becasue the door opens outward like a microwave so it;s easy to use.

[@ubernoob458]

@@FauxHammer Hi what Heygears Station model do you use?

[@axelkarsten9828]

hey! did you remember the shipping weight of this two products and the printer? im looking to get the bundle

[@FauxHammer]

No idea sorry, is it not in the website?

[@Prumpproductions]

It seems the washing thing emits alot of tvoc if used with ipa, the seal is not particularily effective

[@Texas3DCustoms]

So I have the first generation curing machine and trust me that is an improvement I've already had to solder the wires going to the LEDs in the lid because the repeated opening and closing eventually made them snap hopefully they fix that The UI or the controller I should say on the original is horrible it's just bad it's a off-the-shelf cheap timer system it's just bad and hard to control extremely hard to control I have mine set it 10 minutes and I never change anything cuz it is that hard to change they also had a smaller bolt with a bearing ring underneath it on the original version and that bolt did not protrude as far for that reason a little better also it had a red window which I prefer I don't like that green color but that's just a personal thing does it cure better it cures from every angle that's why I bought it and when I bought it that was one of the only ones that cared from all angles and from the standpoint of surface area nothing else back then touched it

[@welshpiper62]

Question would you recommend a brand other than uniformation for wash and cure stations if so which Thanks.

[@FauxHammer]

I quite like the gktwo wash and cure stations. Honestly. None of them wow me… they all do the same thing. I do like this ultrasonic cleaner though

[@jeffmorrison9905]

can you use high speed water based resin and then just use water in the cleaning station

[@Chindogg]

Sorry that this comes so late, had a question. If you're not as keen on the curing station, what would you recommend?

[@KrippledKracka]

Has a consensus on the approximate time frame to run this at been determined? I know you said no longer than 20-30 minutes, but has anyone noticed a difference between say 5 minutes vs 10 minutes?

[@MrCitizen0]

Where do u install the o ring with the ultrasonic cleaner my friend gave me one but not instructions

[@TheFarmoon]

So, what're some comparables? What're the alternatives?

[@Texas3DCustoms]

So the only issue I have with this is for the low low price $259 You get a 7 l ultrasonic cleaner with a pretty interface and a pretty case but you can go buy ultrasonic cleaners that are 15 l which is a lot more parts and bigger plates you can put in for 150 bucks that are heated. Now if you're heating alcohol I guess you run the risk of having combustion because now you're raising a temperature even more but I can tell you cheaper than that but not much You can get a much bigger unit I know a place where you can get a 30 l for $285 and that's a lot of big parts for machines like the Mega 8K The Jupiter and some of these other new ones that are coming out. It is nice that it has a place you can put the build plate but it's designed for their printer which is not that abnormal so now you've got a machine that works great if you have that printer. Happy spring a little bit more say about 300 and some change 305 325 You can get a dual frequency cleaner it's 28 and 40 khz and that inherently could be a little better depending on what you need I don't think you need the dual frequency but in theory 28 kilohertz will help get different areas based on how the resin is working. It's nice product but I mean other than the lid ceiling better than the units you buy that are you know industrial I don't see the value of it over a much cheaper option

[@ubernoob458]

Got any links to the ones you like?

[@Nazrac79]

​@@ubernoob458 but I would recommend replacing the mains inside the unit, may not be necessary but in my experience they are not great

[@printasticuk]

good video, as always. Thanks

[@mekko1413]

yeh i think people claiming the IPA combusts comes from like a single user hearing something from a friend that heard it from a friend who heard it from a friend and so forth to the point all context was lost and they probably were not even using IPA to begin with. I mean this is fairly typical of internet myths like this.

[@StephenBoyd21]

So why not just buy an ultrasonic cleaner for a fraction of the price.

[@azaelames5309]

IS IT NORMAL THAT I CAN HEAR THE HZ SOUND? ALSO IT IS KIND OF HARD TO PUSH THE BUTTONS IN BOTH THE CLEANER AND THE CURING STATION.

[@charlestonskies5605]

If I didn’t already have the ANYCUBIC Wash and Cure station I’d get this

[@Perchpole]

I’m a bit stumped. I currently use the pickle jar cleaning method - which is messy and probably not good for my health. I’m looking to invest in a good automated cleaning station to get rid of all that. However here you state that this system works best only after you’ve first cleaned your prints in a pickle jar! WTF?!

[@FauxHammer]

yeah, that... literally what I said. You can clean in just one device/container but that will contaminate the whole container. What i actually do now, is... Wear a filtered mask. Rinse model in one pickle jar remove and rinse in another pickle jar. Wash in this Ultrasonic cleaner. remove and leave to fully air dry Cure. By using multiple stages, my first pickle jar is the only one I need to regularly empty, then the second jar less frequently. my ultrasonic cleaner has not had a liquid change in over 18 months, but I also use Methys, not isopropanol becasue ISO turns clumpy where methys does not.

[@Perchpole]

@@FauxHammer Thanks. This then begs the question, have you used any cleaning station that does do a better job than the trusty pickle jar approach?

[@FauxHammer]

​@@Perchpole yeah, this one... The pickle jar does only does so much. the ultrasonic will eat into all of the surface level liquid resin and strip it off given enough time. Inside and out of the model too, assuming it's hollowed.

[@JohnVanderbeck]

Does anyone make a curing station that can dry the prints after washing aside from Prusa? Seems like a no brainer to me?

[@GeorgeCarlos28]

What printer did you use for that big Wolverine bust? Thanks

[@SuperTadpole75]

I second this.

[@0x777]

One question remains, how easy is it to get the IPA out completely? I tend to clean my models with IPA, then clean off the IPA with water and I really don't want to buy two cleaning stations to have one for IPA and one for water. :)

[@FauxHammer]

Let it pour through the outlet hose then wipe the rest with tissue.

[@GeekCreek73]

i would like to know if the lid on the washer is sealed tight so now vapors can escape ?

[@FauxHammer]

it;s not sealed, there is a gasket preventing vapours leaving, but this is also apparently lower powered than most other ultrasonic cleaners to prevent this.

[@anab0lic]

Will you be reviewing the Apex-maker X1 next buddy? Currently sitting on a pledge for that thing but not 100% sure if its worth it...

[@arcathar7789]

@@FauxHammer yes ! The sponge under the grid at 2.56 on your video !

[@FauxHammer]

@@arcathar7789 did t even know it had one. I’d contact Uniformation

[@borderreiver7259]

I emailed Uniformation and was advised that the ultrasonic cleaner had only one transducer and is "mainly designed to use IPA or alcohol as a solvent, so the cleaning power is relatively small". Normally you would expect 3 transducers in a 6L tank and it may be that the W320 has lower than the usual 40KHz ones. Bottom line is, it's not so good for normal cleaning tasks if you were thinking it may be. I got a dual frequency 28/40KHz unit instead and if I use IPA/meths I will put it and the model in a zip lock bag as advised elsewhere in these comments.

[@FauxHammer]

That makes sense. I probably should have asked them myself by now

What cure stations have 3 light sources?

[@demjot2967]

I’ve been looking for safer solvents you can run in an ultrasonice cleaner. The brand Liqcreate who I know for making resins sells a supposedly non flammable resin cleaner at 5kg for 75$ so that could be worth a try

[@peterkiss1204]

Alcohols are dirt cheap, excellent solvents and relatively easy to recycle by curing then filtering the saturated liquid. The problem with the miystery washing fluids and different household cleaners is that you don't know what's in them, how will they react to different treatments, and usually aren't willing to evaporate quickly with leaving back only resin waste to cure and dispose.

Sun makes a resin detergent now, non flammable and works as good as iso. Only downside is you have to use the detergent and then rinse with water after

Oh man, my first comment on KZbin... feeling all sorts of lame.

I'm an engineer and have a full maker lab but I'm really interested in a new resin printer but having a bit of analysis paralysis. My biggest issue with the GKTwo is that I can't find any news on an impending wifi module. I really hate using USB keys.

[@FauxHammer]

All i can say right now is give me a month. I want to help but I'm still working on a video which is for people with Analysis Paralysis specifically. because It's confusing to me. So I'm trying to condense it down to the top picks by budget. Also, I know of something coming that will be added to that video which i can't talk about yet.

[@transcendentalidiot3321]

I am thinking of the GKTwo as well. As far as analysis paralysis goes, I set up a pros and cons list for every major purchase I make. I have found the GKTwo checks more of the pro boxes that I'm looking for (particularly the heater and air filter) than cons. Slightly higher price tag/wife finding out, lack of auto-leveling and a network module are definite cons, but the network module is (like Mr. Hammer sorta implied) on its way. I'm waiting on that before purchasing it from the FauxHammer link, of course. 😀
