At least hours. I did a basic 4 inch venture, and it took around 8 hours.
That wasn’t a particularly detailed print. Though different printers take different times. Getting a higher infill, or a smaller layer, can increase the time significantly. (I’m printing it again at a higher quality level, which is taking around 13 hours. Though that’s still a 0.4mm nozzle. 0.1 would make it better quality, but at a massive increase to print time.)
The 13 hour venture’s only 33g of PLA too.
(anything over 8 hours is probably a day. Unless you’re running multiple shifts, which is another expense)
