I’ve had a Saturn S for a while, and I remain frustrated with the results. This is the third attempt at printing a TIE brute wing, files by Modelwerkshop. I’ve tried two different resins and support settings. I can get good test prints, but I cannot get a successful print. These frustrations are why I’ve stopped using this thing time and again. I try to print, fail, deep dive into troubleshooting, get nowhere and step away.

Printer is Saturn S, resin either Elegoo water washable photopolymer resin black or Siraya Tech Blu Lava black and Chutbox for slicing. I have a Mars that works fine, but I got the Saturn to do larger prints. I’m seriously considering just upgrading to the latest Saturn, if I can get the money. Rather try before I buy, but that isn’t an option.

I recently got a Saturn 4 ultra 16k for my first dive into resin printing. I am currently calibrating Elegoo abs like ultra for 25 micron layers using the amerilabs city model. I started at 2.5 seconds, the lowest range they reccomend. I have been keeping a close eye on the checkerboard marks and the spacings, as these are supposed to experence bleedthfough when you get too low.

The pictures above are of 1 second, less than half of what is reccomended. Is this normal? Do I have a machine with a stronger screen than average? Will printing at exposures this low have consequences, even if it's what the resin wants? Any insights would be greatly appreciated

Hi

I have been using my S4U for about 2 years now. It is awesome.

However, after a few months of inactivity due to the cold, I started a print with a large object.

It came out ok-ish, some supports failed. Next print however had a lot of fails.

So I suspected an issue with the screen and took a photo of it.

The first picture is the photo I took when I encountered the issue first time. After this I decided to order a new screen, as my conclusion was, after doing some research here on reddit etc, that the screen has dead pixels.

NB: I have not yet replaced the screen!

While waiting for the screen and after seeing the horrible amount of steps the official Elegoo video shows to replace the screen (really, what idiot designs such a difficult process to replace a consumable...), I decided to just continue printing by placing all objects around the dead pixels. I lose some printable area, but meh, didn't need it.

This worked perfectly, I have printed close to 20 plates using this method.

Then this morning some objects failed.

So I thought, the screen is more broken, more dead pixels. I decided to take a new photo of the screen.

Once again, I have not yet replaced the screen!

I also have not replaced the film. It has no leaks. There is no resin on the screen.

The second photo shows the current state of the screen.

Note that all previous dead pixels are gone and a new spot has appeared.

Now, I am flabbergasted.

All posts here on Reddit say, that those spots are dead pixels.

But my experience now says otherwise.

Does anybody know what is going on?

Has anybody else encountered this strange behavior?

J'ai enfin passé le pas et acheté une imprimante 3d résine. Je suis complètement débutant .Après quelques recherches et visionnage de vidéo sur YouTube, je me suis fait, à l'aide de Chatgpt, une fiche récapitulative. Si vous voyez des erreurs, n'hésitez pas à me le dire, je suis là pour apprendre. Le cônes of Calibration permet de tester l'exposition suivant la résine. Vous pouvez le trouver en suivant ce lien : https://www.tableflipfoundry.com/3d-printing/the-cones-of-calibration-v3/ . Merci d'avance pour vos retours.

This is inner (ring) vat screw from my S4U 16K. I have managed to strip a few and I want to buy more.

It is not countersunk like my S4U 12K, and I use a T8 star. Any idea what size this is? TIA!!

Two minis prints went just fine, and now after several tries, the prints come up as nothing. I've cleaned, recleaned, calibrated. Temp is a little high but nothing disastrous, I think, and it didn't print when it was lower, either.

What could be the issue?

EDIT: This unit has a full enclosure and a vent system, and this isn't a bedroom. I pulled it out of the enclosure to take pictures easier.

Olá, tenho uma Elegoo Saturn Ultra 12k, já troquei nFEP pois no início acabei danificando e ele estava fosco e riscado, já conferi o nFEP está firme, mas mesmo assim eventualmente a impressão falha somente no centro da plataforma.

No geral só imprimo joias, peças pequenas, no máximo 2 a 3cm de altura e 1cm de largura (pequenas joias, anéis, pingentes - sem muita área de contato para cura). Essas peças tem aproximadamente 12x7x15mm

Percebi que as peças nas 2 fileiras laterais, anterior e posterior ficam perfeitas, mas as peças centrais estragam no meio da peça. O suporte está perfeito, camadas de base fixas, mas ela falha no meio da impressão. O espaçamento entre as peças está em 3,5mm e no geral imprimo cerca de 50 a 100 peças por plataforma a depender do tamanho delas.

Uso resina própria para fundição, com alto teor de cera, mas independente da resina, até nas com menos cera, a falha ocorre sempre no centro depois de alinhados todos os parâmetros.

Alguém já teve algum problema parecido, como resolveu?

Can't send file despite a reformat of the internal storage, thumbdrive, and factory reset.... thoughts?

So I just found my boy here about 90% done with the job claiming it was complete, usually I find the handle sitting way higher once it’s done with the job so I tried the return to home setting, didn’t move but the basin tilted a bit. So I tried restarting it, nothing. I tried through the tool menu to move it 50mm up, nothing. Any advice? Factory Reset?

Saturn 4 Ultra - Same print succeeded once, then failed on second attempt. Any ideas?
I’m trying to diagnose a failed print on my Elegoo Saturn 4 Ultra.
Printer:
Elegoo Saturn 4 Ultra
Anycubic Water-Wash Resin+ V3
Settings:
Layer height: 0.05 mm
Normal exposure: 2.5 seconds
Bottom exposure: 35 seconds
Default Saturn 4 Ultra settings otherwise (tilting vat, so no lift speed settings)
The model:
Large ruined building wall.
I added my own supports.
The model is solid (not hollow).
The issue:
The lower half of the print came out perfectly. Around halfway through, the rest of the model detached and ended up cured onto the PFA film. The model somehow continued to print and cover the failed area. The printer continued printing the upper section, but near the failure point some resin was stuck to the film.
The important part is that I printed this exact same model immediately beforehand with the exact same supports, orientation, resin, and settings, and it printed perfectly. Nothing in the slicer changed between prints.
After the failure, there was a cured section attached to the PFA where the missing half should have been.
I’m wondering what could cause a one-off failure like this when the previous print was perfect.

Im quite new to SLA printing. I had a BambuLab P1S, yet was unsatisfied with the quality of my miniatures… Finally gave resin printing a chance and got a Saturn 4 16k! I got it two days ago, so it’s still brand new.

I printed out an austroraptor bust. Came out perfect the first time. It was at 32mm. I scaled it up, printed it again, came out perfect, no issues. I wanted to reprint it since I broke off some of the teeth. But the second time I attempted to reprint the scaled up version, it looks like the layers stopped sticking halfway through the print. Im confused since it printed perfectly the first time. They were only printed about an hour apart.

What exactly could have caused this? What can I change in my settings to prevent this? Its like it stopped curing my layers halfway through.

Im not home at the moment, so Im unsure if the rest of the print is in the vat.

Howdy all. I have a Saturn 2 that is suddenly giving issues and I can’t seem to resolve it. Wondering if the community has ideas. The failures seem to be flat bottom layers that just stick to the nfep film. I use lychee slicer and the line support raft usually gives no issues.

To sum up my attempts to fix:
Screen works, I’ve tested it.
New nfep film installed correctly.
Leveled build plate (and re-leveled just to double be sure)
I’ve tested a model several times now that USED to print just fine, now about a month or so later nothing prints.

The model is a miniature size creature with its center body being the largest part. If I try to print the body alone with nothing else dead center of the screen, it prints fine. The moment you put other parts, none of it prints. I have rearranged the model parts to spread out suction forces or weight distribution, and I’ve increased exposure of bottom layers, did some scuffing of the plate with sandpaper too.

At wits end, can’t figure out what’s wrong.
