Over 90 3D Printed Bus Shelters Installed in the Indian City of Chennai

The Indian city of Chennai currently has around 1,420 bus shelters. Many of them are in poor condition, and their usage is limited, if not abandoned. However, thanks to additive manufacturing, this is set to change! In the future, Chennai is expected to have nearly 90 3D-printed bus shelters. In the long term, 3D printing will give bus stops more functionality and “glamour.”

Collapsed roofs, seats that are too low or too high, and walls covered with posters should soon be a thing of the past for bus stops in Chennai. The Greater Chennai Corporation (GCC) has announced its intention to remedy these problems using 3D printing. Last September, the first 3D printed bus shelter was installed near Marina Beach. Others followed at the Anna University stop on Sardar Patel Road and opposite the TWAD building on Kamarajar Salai. But it doesn’t stop there. In the coming months, other bus stops will be renovated using 3D printing.

3D Printed Bus Shelters Combine Functionality and Aesthetics

The 3D printed bus shelters feature an innovative concrete structure created using 3D printing. There are also grooves on the reinforced concrete columns. This gives them an organic appearance, reminiscent of a tree trunk. Additionally, the surface texture makes it impossible to place poster advertisements, thereby preventing vandalism. The scarlet metal benches also provide a strong visual contrast to the gray columns. The new bus shelters are not only eye-catching, but they also stand out for their functionality, as the oversized benches are placed at an optimized height, which contributes to greater comfort. The GCC did not achieve this without obstacles, as the oversized benches were challenging to install due to the limited space.
