A commercial 3D printer is purchased for $ 320,000. The salvage value of the printer decreases by 50% each year that it is held. The cost to operate and maintain the machine the first year it is used is $ 12,000; these costs increase by $ 6,000 each year. What is the optimal replacement interval and minimum EUAC for the printer, assuming a MARR of 15% is used?
