The global market for 3D printing in construction sector (including various technologies that use 3D printing as a core method to fabricate buildings or construction components) is poised for solid growth over the next six years with a compoud annual growth rate (CAGR) of over 16 per cent by 2025, according to a new report.

The key 3D printing methods used at construction scale include extrusion (concrete/cement, wax, foam, and polymers), powder bonding (polymer bond, reactive bond, sintering) and additive welding, stated Report Consultant, a high-end research group.
Alternative terms are also in use, such as Large Scale Additive Manufacturing (LSAM), or Freeform Construction (FC), also to refer to sub-groups, such as 3D Concrete, used to refer to concrete extrusion technologies, it stated.
