3D Scanning

3D scanner is a device to capture the size and shape of a physical object into digital 3D presentation. 3D scanners are the fastest and automated way to assist in creating 3D model prototypes from physical objects. The Library provides 2 types of 3D scanners, a handheld and a desktop 3D Scanner, you may choose a suitable one according to your needs. Walk-in are welcomes, reservation via iBooking system is recommended.
