So, I have a bit of a problem with print volumes and the amount of resin used.
I am printing something that should, in total, use 9ml according to both Prusa and Chitubox.
Weighing it afterwards, it uses more like 11-12ml.
Im printing them in batches of 3, 35-40ml total.
Yet an almost full vat (measured at 60ml, so probably 50ml ) leaves the prints failing due to lack of resin.
Could it be that the last 10ml are not corretly located in the vat to finish the print, or is something else weird going on?
Any advice is welcome as I'm at a loss to whats happening
所以, 我對印刷量和使用樹脂量有點問題.
根據prusa和chitubox, 我正在列印的東西, 總共應該使用9毫升.
之後再重, 使用11-12毫升.
我正在列印它們, 總共3毫升.
然而, 一個幾乎滿的增值稅(測量為60毫升, 所以可能是50毫升), 因為缺乏樹脂而導致指紋失效.
可能最後10毫升沒有在增值稅中完成列印, 還是發生了甚麼奇怪的事情?
任何建議都是受歡迎的, 因為我對發生什麼都感到迷失

Is it hollow? Could some resin be trapped inside?

I don't think the volume calculations take into account any support material? are you weighing it after support material removal?

the supports are very minimal, and Im weighing the raft and adding a little extra for the rest of the supports. And I calculated it with support material in both chitu and prusa...

No, very thin parts, only about 3-4mm thick

Probably inside the print. Like parts between hollowed areas. Sometimes when you Hollow the print, it seals off another part of the print that is also Hollow, but fills with resin because there are no holes for resin to escape from these sections. Check for that. It happens a lot on prints I've hollowed.

Nothing is hollow, the parts themselves are quite small, only 3-4mm thick.

How about the resin that sticks to the model and gets washed off afterwards? It is known the software estimates are showing less then used in real
You’re using resin on places the software doesn’t take in account

Resin is stuck to the print, that is washed off, that can be quite substantial... so there is "loss" there.
Then there is resin that "sticks" to the buildplate, when your print is done, you will most certainly see some resin dripping off... leave it fo
r long enough to regain most of it.
And then there is the resin that goes "on top of" the buildplate, since the build plate goes into the resin, there will always be some resin left on the non-print side....

Resin sticks to the model and the plate as it prints. That's what you have to clean off before final cure. Not a huge mystery.

Ahh, i think i have tricked myself by trying to be clever. I usually leave the prints waiting for an hour or so before cleaning to let the resin drip off. That would explain why there's resin left over but the print failed.
Thanks

I do that myself. I think the longest I've let them 'drip dry' was 2 weeks. lol
Hope you get things squared away!

add more resin mid print, just be careful not to create bubbles. and careful not to shake the printer during opening, is difficult to gently open the door sometimes
