NPCA Staff Report
While the technology powering 3D-printing has been available for decades, the process continues to expand into new markets with applications much larger and more diverse than small, plastic components. Single-family homes, apartment complexes, office buildings and entire communities now can be fabricated with 3D-printing using cementitious materials rather than plastics and resins.
Entities across the globe currently are using the technology, materials and equipment to produce 3D-printed concrete structures. A company in Austin, Texas, for example, is 3D-printing concrete houses to provide fast and affordable housing solutions. Each home can be printed in just 48 hours.
However, innovation in 3D-printed concrete isn’t limited to structural applications. There also has been growth in 3D printing architectural concrete features.
3D-printed concrete requires unique mix designs and special equipment, and job site limitations also can constrain operations. However, the speed, versatility and ability to manufacture structures without formwork provides major advantages in some applications.
