An average human requires a 32 slot medical chamber according to the rules. Imperial regulations bumps that to 50 to cover virtually every human, no matter how massive or obese.Never implied they were. I was just extending Anstett's musings. But they may be significantly denser than humans. Say, 1.25 times?
In any case, it all still comes back to dimensions, not density. Estimating how many litres of fabricator you will need to print a body or body part is going to be based on its height, width and depth. So unless the print is conveniently shaped the same as the cavity, you will usually need a lot more volume of fabricator than the print has.
A robotic slot is 1.5 liters, so a 48 liters would accommodate an average human, according to the rules.
You can use that as a scale for smaller chambers for body parts or skimp and save to get one that works.
