Structure Of A Miniature Quadrotor

Structural parts of a miniature quadrotor has been fabricated using the shape deposition manufacturing. To enhance the rigidity f the elements and also make the system more shock resistance, elements machined of aluminum sheets has been deposited in the parts. Also to eliminate the need to wires, the aluminum elements has been used to distribute power.

The first step was to machine the aluminum parts and wax block to the prepare the negative mold.

The aluminum parts are then placed in the wax block properly.

Liquid poly-urethane plastic with a shore hardness of 70D has been molded in the wax block.

The parts are then taken out and assembled.
