Construction with precast concrete has been around for a long time. They require molds, and typically are limited in form because the more molds you need to make the more expensive the project gets.
With printed concrete, 10 unique slabs should have the same, or close to the same, unit price of 10 identical slabs, which (when the price approaches precast in the near future) opens up all design possibilities for architects currently restrained by budget.
