For 3d resin printers, height is the biggest factor in time to print. Detail = layers. Layers = seconds. But you do every layer in about 5-8 seconds. (*not counting all the other variables....) You can print a full block one inch tall the size of the build area as fast as you can print a single pixel, one inch tall. The Mars Pro 2 has a resolution of 1620x2560.
At relatively the same quality, I can print 3 t-72s standing up in about 6 hours. I can print 1 t-7s horizontal in 1 hour and 33 minutes.
If I am there to babysit, I can print them 1 at a time. If I'm going to sleep, I can just print 3 and wake up to a finished print. 3 vs 5 for the same 8 hour period.. (Sleep, I highly recommend it.) So grinding... that's 13 tanks a day...
Your mileage may vary.
