The Asiga Pro 2 or MAX could easily print 8 full arch models or more models in 8 hours or less... The attached picture of stacked models took about 4-4.5 hours to print... if you removed the bottom layers and only printed the 4 full arch models on the top layer from the picture, your looking at 2.5 - 3 hours tops to print those 4 full arch models vertically. Asiga Pro 2 has the largest build plate and z axis (verticle axis of 200mm) The Max has a slightly smaller build plate and a Z axis of 75mm. Pro 2 is $24,990 and the Max is 13,990
