3D printing in construction has primarily been associated with housing, like China's WinSun villa and Icon's Texas project. However, as the technology advances, its applications are diversifying. Henrik Lund-Nielsen notes that while it's used for walls and foundations, it can cover only a portion of a structure. This limitation leads experts to explore 3D printing's potential in creating bridges, tunnels, wind turbine bases, tanks, and industrial structures.

3D printing's benefits include: speed, reduced reliance on skilled labour, economical concrete usage, lower waste, and embodied carbon. However, its application is still limited in the sector. Among the barriers, there are: technological challenges, regulatory hurdles, and traditional mindsets. However, industry insiders are optimistic about 3D printing's growth.
