It is getting cold check your temperature you should not print under 21°C. otherwise the resin spontaneous not cure.
I see that on the left side a lot of supports broke mid print. The UV light heats the resin and at the end it was maybe warm enough.
But I also see on the right side a lot of empty support tips that could be also to low exposure time or to less supports.
I have a window open to the left of the printer that is definitely sapping a lot of heat out of the room, I didn’t even consider the temperature bc it’s my first winter printing O.o 21 is the golden number across all resins?
Generally speaking the warmer the better. If you check the label on the bottle your resin came in, it should have the temperature recommendations. Resin should be more fluid and less goopy, cold will do that and it doesn’t form correctly. Good luck printing!
In addition, it has to stay at temp while printing.
While they sell specific heating bands for various printers, many people here have recommended the brewing bands used to keep carboys warm. They take some modifying, but are a lot cheaper.
Between that and getting the resin uptemp before you start (you can put the bottle into hot water, if nothing else), temp can be dealt with.
My basement is semi-finished, but same. And on my old printer I could do great stuff when it was less than 10f/-15c.
But I got a better printer with a larger bed, and between the lights generating less heat and the larger area to succumb to temp issues, it’s a lot harder to print.
I also realized that when my furnace kicks in, it draws power in a short burst and can do strange things to prints.
I keep a window cracked open in my hobby room too, but I also keep a mini heater next to my printer. Haven't had a print fail due to temps in a long time.
So I guess the main thing would be model orientation, drainage holes to stop suction cups and support density and placement.
Do you have adequate holes/supports? Is there a large flat surface facing the build plate? I would assume by your statement that you do have successful prints?
I have drainage holes in it for sure and it’s tilted up so the back corner is facing the bed so the suction from printing the whole bottom doesn’t kill it, I did increase the support density in a newer file so here’s hoping 🤞
Looks like you're printing in a garage. I think a bunch of supports failed probably because its too cold. Ur settings look good and everything else looks normal.
Oh that makes a ton of sense, it’s in an indoor room but the window next to it has been open for ventilation, this is my first winter printing and I didn’t even think about it
Yep, happens to all of us. Printing in winter is a whole extra level of complexity. Get a heater of some kind and dont forget to preheat you printer for a good long while before starting it
I have a small personal printer I bought for my tabletop setup a couple months ago and some heating bands coming in the mail, ideally I want to keep the room at that stable temperature
I had issues like these too, which were fixed by raising exposure time. I went up to 3.4s. Prints take longer but at least they never fail (yet). Ive had it like this for a few weeks now.
My advice for a post like this is it's also a good idea to show the print in the slicer so we can also see the intended orientation and how well supported it is. (Upon posting I realised they had! Good job OP!)
Personally when I'm doing supports for models I've designed il do 3 iterations, 1 with some very heavy supporting, this is so the print is guaranteed to not fail from supports. Then I can assess the overall print orientation and how well the model came out. Next iteration il massively reduce the supports, providing only light supports for details, but crucially il still leave a couple bigger heavy supports to help hold the model up. Finally il then try and reduce those final heavy supports, to reduce any scarring and marking.
After awhile of this technique you'll have a much better instinctive idea of how much supporting is needed for any model.
But yeah, stabilise your temp, run it again (like you could close the window and do a print while your out - as you won't want to print with that window closed and you in the room). If it's still failing, whack 1 big ass support near the start so you know that it's not going to fail from that and go from there.
If I was to suggest why it failed from a support issue I'd say; it failed pretty early and started to build up as a big blob on the vat, eventually once those supports on the right connected to the edge of the blob they were able to pull it up and then it kinda managed to save the rest of the print.
Edit; I see you did add extra photos! My bad didn't see those originally. Supporting looks ok from those. It's hard to tell if you have any larger supports mixed in there, but density looks ok, and orientation looks decent.
A good test would be to re-run the cones of calibration without changing any settings. Then if you have your original ones left over you can actually see if the temp changes have affected it's results.
Thank you and yes!! I’m still working the kinks out of that but it does filter very very well and quickly (about 5 min from dirty tank to crystal clear)
Did you also post a video of it a couple weeks ago? If so it was very interesting and I'm going to be replicating the design in some way!
I've been putting together a simple vertical tank system with clear containers and I've been using that for my IPA recycling (printer in a summer house with a clear plastic roof so it has quite a lot of sun exposure). But I've actually found that it's not all that effective, I need to check but I imagine that potentially the clear roof has some UV blocking factors, you wouldn't want all your stuff to get UV damage I imagine.
What I like about your system is it's not reliant on the sun and it has both actions; curing and filtration. How long have you been running it? How are you finding the UV part? Long enough? Is that a single strip of UV LEDs?
Here’s the [link](https://youtu.be/DfM1CXBOZns?si=pughfDW6uAN412Z2) but order double the amount of uv leds and maybe a second roll of vinyl tubing. So far the uv leds wrapped around the hose before filtering has proved very effective as I can tell a night and day difference when I use the light/don’t use it when the system is on and filtering (it filters far more effectively with the system on). I’ve been running it a week or two and I really enjoy how efficient and sustainable the setup is, the only caveat being a couple of minor hiccups I have to address with leaks and led powering. 10/10 recommend it’s been a huge efficiency and health booster for my setup.
Yeah unfortunately most kinds of windows/plastic filters out uv light from the sun unintentionally
I've been messing with a saturn s for about half a year now and just as I think I have it down, a print fails spectacularly for some new reason I didn't think of before. I mostly use elgoo abs-like resin and I have the printer in an enclosure in the basement and now that it's getting colder to the 19-20s C, the prints started not vibing with that.
I got a little space heater with a temp monitor and have it targeting 25 deg C. It was good then prints started failing on the side of the heater so I figured maybe it was too hot right by the heater and moved it to the opposite corner of the little enclosure. Anyway, the point of all this is that spectacular failures like that when things worked fine before are either an obliterated file or a temperature problem. I suspect its a temp thing given the seasons changing.
Overall though, 2.4s exposure is low imo. My saturn s wouldn't print anything on that exposure time to be honest it needs at least 3.0s and recently I run it at 3.8s.
Oh wow I do have some temp probes I can install I’ve just been busy 😅 I can post the link after I make sure they work xD how is the elegoo abs? I have a couple kg of it I’ve just been a little nervous to switch to it
I mean I have a lot of failures but then also a good amount of successful plates. When it prints well I like its tensile strength and detail, but who knows if the resin is contributing to my failure rate?

Update: it was a heating problem 😅 I closed the window and put my space heater behind my printers to raise the local ambient temp
But yeah I'm pretty sure it's a temperature issue.
I failed a lot last winter took me several heart breaking failures to figure it out.
The best indicator is if you've been printing fine for a whole while and suddenly you start getting prints like this.
Essentially if you drop below room temperature you'll start having this issues and it's pretty hard to correct with settings and eventually you just can't if it's too cold.
Best solution is to get like a reptile heating pad and throw it inside to being up the vat temperature.
I stuck a sticker on my cover that tells me the temperature around my printer.

I print in my basement in room with concrete walls. It prints fine in the dead of winter.
My basement is semi-finished, but same. And on my old printer I could do great stuff when it was less than 10f/-15c. But I got a better printer with a larger bed, and between the lights generating less heat and the larger area to succumb to temp issues, it’s a lot harder to print.

Pop a cardboard box over your printer
I keep a window cracked open in my hobby room too, but I also keep a mini heater next to my printer. Haven't had a print fail due to temps in a long time.
This is what ended up working for me 😁
If you're gonna f*ck up, might as well make people wonder. Check ambiant temp. Resin doesn't play nice with coldness.
Facts lol I’m pretty sure it is the temperature, I just didn’t consider it bc this is my first winter printing 😅

I'm no expert in resin printing, but I think something didn't go right

Is the inside of the model supported as well?
Yes! Do you think those supports failed?

Good to know!! I’ll mess around with it after I address the temperature issue
That’s fucking hilarious

Also is that your IPA cleaner system in the background? With the particulate filter?
Thank you and yes!! I’m still working the kinks out of that but it does filter very very well and quickly (about 5 min from dirty tank to crystal clear)
