NTU students create two eco-cars for 2015 Shell Eco-marathon Asia
A group of students at Nanyang Technological University (NTU) have created Singapore’s first 3D-printed urban solar electric car. Mounted on a carbon fiber single shell chassis, the NV8 may also be Asia’s first 3D-printed urban concept car. Utilizing 150 parts, the 3D printed body of the EV which will compete in the Shell Eco-marathon Asia was designed at the University itself. The 3D-printed cabin of the car is made from lightweight plastic to offer more space and comfort to the driver and also to keep the weight low. The urban concept car can reach a top speed of about 60 km/h (37 mph), while maintaining low energy consumption.
To keep the 3D-printed NV8 electric vehicle strong and lightweight, the team have integrated a honeycomb structure and a unique joint design to hold the parts together. It took the students about three months just for printing and assembling the body shell of the car. Measuring 3.2 x 1.3 x 1.3 m, the NV8 weighs 120 kg, features vertical opening doors and has a mileage of 425 km.
Nanyang Technological University students have also built the NV9, a slick three-wheeled racer for the competition. Featuring hand-made silicon solar cells, the NV9 can take sharp corners with little loss in speed due to its unique tilting ability inspired by motorcycle racing. Both these eco-cars were designed and built from scratch by two NTU teams consisting of 16 students from the various engineering schools over a period of a year. The NTU Venture (NV) 8 will race in the Urban Concept category at this year’s Shell Eco-marathon Asia whereas the NV9 will participate in the Prototype category at the event which will take place in Manila from 26 Feb to 1 March.
