80x80cm is pretty massive build for a 3d printer - we have 4 printers at work, ranging in cost, and even our £70k unit with (what we think is a pretty decent build size) isn't this large.
But, I guess it depends your budget, as you've not specified... I guess, if you're wanting to spend many k, then I guess you might get lucky...
Ultimately fine detail and a good finish means lots of small layers, this does not go hand in hand with large builds, so a combination of both will be v expensive.
as an example - to get that kind build size, you're probably looking at something like
https://www.aniwaa.com/product/3d-printers/stratasys-fortus-900mc/ - so, it looks about £250k. Now, I'm guessing that's not your budget, but who knows?!?
for cheaper options, as a comparison, I've just seen this list:
