1. Increased complexity: 3D printing can create complex shapes and structures that would be difficult or impossible to build using traditional methods, such as curved walls or intricate details.
2. sustainability: 3D printing can use recycled materials and reduce waste, making it a more sustainable option for construction.

Some examples of 3D printing in construction include:

1. Building houses: 3D printing has been used to build entire houses, including walls, floors, and roofs, using a combination of concrete and other materials.
2. Creating infrastructure: 3D printing has been used to create bridges, roads, and other infrastructure, such as drainage systems and utility tunnels.
