question about astroprint

astroprint says that a 5 inch articulated robot will take 30 hours, is this a miscalculation?

After months of 3D printing, I realized I had this “articulated robot” at 45 speed, 100 infill and 0.1 mm layer height. :expressionless:

At the time I posted this, I JUST got an Ender 3 Max.
