Well, it depends on the way you have to print.
In generell resin will be refulled while print processing, if you need more than 200ml.
In my case I have nearly all prints at max use of 200 to 220 ml which can be run at one.
To be able to use the resin profile I want I got the Universal cartridge by https://protoart.net/
But I do not fill them - I just pour the resin manually. At some Vats I fixed the senor with a chewing gum so there are no refilling from cartidge any more.
The Vat has a volume of about 500ml - so printing a 350 to 400ml should be possible without refilling.
If you want to get sure there will always be enough resin, just pause the printer and refill in the pocess.
Well… that is how I run it.
And it works.
