- Realized I had a printer sitting idle for over a year, in a room with some ambient light, decided to test something I had been wondering about...
On Dennis Wang's Channel since he started using the Chitu systems UV Light Meter he has made a few tests. With the recent review of the new Sonic Mini 8KS printer he tested the covers of his printers how much UV light from a UV lamp they let in. The brown/smoked one in the Sonic Mini 4k let in half the light, a known problem with it, while the orange cover from the 8K and yellow from 8KS let in zero UV light.
Good to see you're back!!!!👍💪
Wow, you are back!! Good to see your presence on YT again! You inspired us to do what we do!!
Thanks for the vid. I havent done any resin printing in over a year. I at least a couple hundred dollars of resin sitting in a closet that hasnt been opened. all the manufactures say that resin is only good for a year so I was worried none of it would be any good but I guess now I know it will be fine.
Great to see you back. I just recently bought a Mars 2 Pro (for like $150 on sale, I guess it's because of their new releases) and I've watched a lot of your older videos about slicing and supporting and fixing sliced files before printing.
Welcome back!
This makes me happy to see... Currently going through something similar to what you explained in your last video and I'm glad to see that it should still work once I can get back to it
Great to see you back, Greg. I just discovered this for myself at home after not printing on one of my machines for 6 months!
I did the same thing, but it only sat there for 6 months. It was clear green resin and all the colour sank to the bottom. Still worked perfectly. Clearly illustrates the fact that you can just leave resin in the vat.
Wow, interesting results, I wouldn't have guessed that.
Also, yeah you can leave that stuff out for a while, far longer than manufacturer's suggest or recommend. Cool test, longest I have left stuff out was about 2 months, but 1 year is epic, and cool to see that it works!
Figured that was the case. I've had some in mine go for a few months with no ill effects (once it was stirred thoroughly). Welcome back, btw.
Ooo thanks for answering a question I've been curious about! Good information to know!
I can confirm it's the same with Elegoo Water Washable resin.
thats great to know as i have 2 unopened elegoo water washable bottles but they are both of of date so hopefully the resin will work one is out of date with over 2 years i wonder will it still work as i have not got around to doing much 3d printing yet all the best
@@james6609 That bottle is 3 years old in 2 months, and still works great
@@asfodhell brilliant thank you so much for the information best regards
Thank you very much for the video! I had resin sitting on my vat for 3 months since I got too busy with work. Cleaned it up on my free time and worried about the machine and resin. Glad nothing has changed seeing you've tested it out.
Dennis Wang tested the covers with 7v exposure test for Windows the proven case and the others were 0 light bleed so yeah they do the job as intended!
I had Anycubic's Grey Eco Resin sitting in the vat in my basement over the winter, in under 10 degrees Celsius. No problems printing with it after a good stir once the temperature started rising in the basement again. I've also been printing with that resin without problems down to 13-14 degrees Celsius.
i leave my resin in the vat most of the time.... and have left it for multiple months, maybe even a year, and i did not have any problems printing, but stirring the pigment back into it was 20x as difficult..... all the pigment had settled into the bottom, and became really thick, it took a while to get it to separate, but it eventually did, and spread back out like normal. I did however notice, when i changed colors, there was still pigment in the crack between the plastic film, and the vat frame, which couldnt be stirred back in due to its location, and i had to clean that out, more so then normal as well.
I am in this EXACT situation. Have been nervous about it. Going to send it too
My Saturn, with the red cover, and an additional cloth over that, sat for about a year.
I pulled out the vat to check it out and discovered that the the resin at first glance, appeared to be fine.
So I decided to empty the vat for a general inspection and cleanup of the vat and the FEP membrane. I poured all the liquid out into a temporary, opaque, container.
When all the liquid was poured out I discovered that there was a perfectly flat, single layer (50microns?) of cured resin (I'm guessing... but it was Very thin) adhered to the FEP.
Getting it cleaned off proved to be, well, problematic. I ended up deforming the membrane, and so opted to just roll with it and replace the membrane.
Odd that the cured layer would be at the bottom, and not on the surface.
The printer has been unplugged the whole time, so I can't see how the display could have accidentall illuminated, and cured a layer...
Anyway, that's my (rather lengthy) story.
Cheers!

My anycubic has been sitting since last summer waiting for me to clean the garage and start back up. So it’s been almost a year and many subzero nights.
We shall see.
This happened to me recently and I tried it out myself! Also worked perfectly!
Thanks for this mines been sitting there for 18 months was dreading clearing out, checked it last week by coincidence snd it was still fluid, so now I think it’s prob fine! Elegoo mars2 and Elegoo resin. Thanks again.
I am also hoping to test this out in a couple months...
good test I left my resin in my basement for like 2 weeks... definitely got colder and it created like a weird purple film on the top... looked like anti freeze... and the consistency of it got changed... so I just mixed it and it printed fine
Glad to see you're back! Did you preorder anAnycubic M5s?
I had resin sitting in my vat in my saturn for almost 2 years and it worked fine after mixing it a bit. i dont remember what kind of resin it was but i think it was the cheap stuff you get at microcenter. maybe i should go clean that vat out sometime.
Well, that's good to know, since I haven't used my printers in a year.
Ive tried twice using the resin that sat in a vat for a year+ and both times it works. Just stirred it up good and made sure to get the milky layer off the fep and was good to go. I actually have one to try soon thats been in it for quite some time lol im sure you have countless vats and printers nowadays so maybe a follow up video could be testing different types/brands of resin
good to know! mine has been sitting for 8 months lol
I was mildly worried the bottle I had started on might not be usable after taking the winter off printing but I’ll have to give it a go after seeing this.
Yeah man, let's go.
I get the feeling that this sort of thing falls squarely under YMMV.
I had read somewhere that resin had a shelf life of 6 months? I'm new to resin printing so I have no idea if that's true or not. Good to know this worked still after a year.
Depends on company it seems, my elegoo resin seems to work fine even after a long time on shelf, my clear resin from another company made a mess of one of my vats
I've always heard of shelf life with the resins but haven't encountered any problems myself. I just used 2 resins last year that were from 2018 or 2019 and they both worked. I also used some elegoo resin twice that sat in the vat for a year+. I'm really curious if shelf life correlates to brands, types or colors
The rich opto orange printed a goo blob after expiration date for me, it was the clear orange, maybe if I extended layer time it might print.
Nice video. Will you test anycubic m5s?
I had a bottle of rich opto clear Orange that was one year out of date. I shook it forever but it still wouldn't print anything.
Modern uv shields on printers are capable of blocking 100% of UV light.
So, unopened bottles of resin sitting in a cupboard for nearly 18 months should still be fine, then? 😮😄
See, when I did this, the vat leaked, badly. So be careful. My Qidi 8.9 Mono still works, so that's great, but I had to replace the magnetic build plate, as it fused as I had left some prints on the build plate. (I wasn't able to access the area it was held in, and forgot that there *was* a print, until I was able to clean the room enough to get to it, that is...)
How was the screen? When you took vat out? Normally after 4 or 5 days you get that smudging from the fep going soft and resin separation I've seen it effect detail this screen smudge like you have drawing on a tablet and leaving a palm print on the screen! This must have been OK or did you wipe it clean first? I'd be interested to know about that.
Yeah, you look exactly like a dude who is into the Punisher lmfao. Take from that what you will. Great video regardless, glad you’re back after some hard life struggles.
There is now a file to print and it stirs the resin in the vat.
I tried printing my resin that was in the bottle after a year, and didn't print at all, didn't print anything. I even left my printewr at 100% Test and nothing hardened at all
I'm curious of the brand, type and color? I have resins from 2018 or 2019 that I used some just last year that worked fine. Knowing it was old I I shook it up like normal, then shook the hell out of it. I let it settle a little bit and then shook it up again for good measure. It ended up printing fine though. One bottle was opened already and one new. One elegoo gray and one anycubic green from the og photon. Also had resin that sat undisturbed in the vat for a year+ twice that work after simply mixing it up inside the vat. The printers are in an enclosure and don't see any sunlight and it's also airtight so that could play a part in it I suppose
Do you have any idea what the Use by Date was?
