One of the most common problem that disabled persons with amputation in upper limb they couldn’t buy a commercial prosthetic hand because it very expansive and up to thousands of dollars, Researchers and developer aspire to manufacture an prosthetic hand that performs the same functions and activates of natural hand. This paper includes the design and development of a low-cost prosthetic hand (less than a1000$) that capable of wearing from the persons who has amputation in the hand, this design represent a hand with five finger capable of movement and gripping the object, rotatable wrist and socket connect with amputation body capable to up and down the forearm . The design of this prosthetic hand possess 18 degree of freedom (DOF), 3DOFfor each finger except the thumb has 4DOF, 2DOFfor wrist and 2DOF for socket. The design prosthetic hand work by under actuated system 7 servo motors with tendon to move the fingers material (PLA). The design element and tesht in solid work to avoid overlapping between fingers and then after manufacture the design try it in real life to movement and gripping the object. Keywords: Prosthetic hand, degree of freedom, 3d printing, solid work.
