Abstract :
Gears are power transmission devices in between input and output of machines, these power transmitting elements are very compact, and they transfer power with minimum loss. Due to the nature of their different speed ratios they are used for different applications like high speed marine engines, automobiles etc. Different materials are used for preparation or fabrication of gears like metals steel or brass , plastics nylon or polycarbonate . In this project spur gear is designed by CAD software and fabricated by using 3D printer, for 3D printing materials require like plastics or ceramics but for this project plastic material is used that is polylactic acid PLA . By using 3D printer spur gear is produced within a small period with better dimensional accuracy than conventional method like milling etc. P. Naresh | Aman Raj | J. Tarun | Ejazur Rahman | G.
