CPWD uses 3D printing for defence construction in border areas
UPSC / SSC current affairs note
Why in news
For the first time, CPWD has built a watch tower for the armed forces in Jammu using 3D printing construction technology in just 45 days. This project demonstrates rapid construction of critical defence infrastructure in border areas, where conventional methods take over a year due to difficult terrain and logistical challenges.
Background
The Central Public Works Department (CPWD) is the central government's construction agency. 3D printing in construction uses computer-controlled machines to layer concrete automatically, making construction faster, more accurate, and less wasteful.
Key facts
CPWD built a forward duty point (watch tower) for armed forces in Jammu using 3D printing.
Construction completed in 45 days; conventional method takes over a year.
Project aimed to demonstrate feasibility of Concrete 3D Printing Technology in high-security, remote locations.
Structure is ground-plus-one storeyed with water supply, sanitary systems, and electrical installations.
Challenges included restricted site access, security protocols, and logistical constraints.
3D printing enhanced construction speed, precision, and resource efficiency.
