The construction of buildings using concrete has been around since the time of the Romans. In all those centuries, concrete structures have been built using essentially the same method: forms, reinforcement, mixing, pouring, setting, repeat.
The process is costly and time-consuming. The construction of the forms alone demands dozens of workers and requires a substantial amount of lumber, keeping labor and materials costs high. Builders might save some time using prefabricated concrete blocks, but such materials are not appropriate for every construction project and carry their own expenses.
For the first time in history, builders have an alternative to traditional concrete construction methods that are more cost-effective, less expensive, more environmentally friendly and allow for a wide range of possible construction projects. Three-dimensional concrete printing for construction has emerged in the building field as a viable and efficient alternative.
