3D-printed car to represent Singapore in Shell Eco-marathon Asia
03 Feb 2015|3,028 views
The future of green car technology could lie in 3D printing. Two eco-friendly cars, one of which is the first in Singapore to be made using 3D-printed parts, were unveiled yesterday by Nanyang Technological University (NTU), reported The Straits Times.
The 3D-printed prototype, called the NTU Venture 8, has a cabin made of printed components glued together using epoxy adhesive. A total of 150 panels were used in its construction - the largest assembly of 3D-printed parts to be put together here. Each of the 3D-printed components is made from acrylonitrile butadiene styrene, a lightweight plastic. Coupled with the aerodynamic design of the vehicle, it reduces drag, which makes the 120kg car more energy efficient.
While the plastic shell is only 1mm thick, it is strong enough to handle the weight of the vehicle and the driver, because of the honeycomb structure used by the student designers from NTU's College of Engineering.
Said Associate Professor Ng Heong Wah, who mentored the 16 students who built the car, "We are extremely proud to have designed and assembled a 3D-printed body shell for the electric car, which is Singapore's first and probably Asia's first. The 3D-printed car body was pushing existing technology to the limits."
Currently, 3D-printing technology is used for smaller items such as architectural models.
The second car is a three-wheeled vehicle that, with a sleek shape resembling a bullet, has a unique tilting ability.
Team member Winston Tan, 27, said, "We took our inspiration for the tilting mechanism from motorcycle racing, where racers lean left or right during sharp turns to maintain their handling and speed."
Both cars are powered partially by solar cells mounted atop their frames, and will race at month's end in the Shell Eco-marathon Asia in Manila, an annual competition that challenges student teams from around the world to design, build and test energy efficient vehicles.
