7 Year Old Girl Gets 3D Printed Prosthetic Arm

Meet 7 year old Faith Lennox. She's spent most of her life missing part of her left arm. That all will change with a new 3D printed prosthetic arm.

Perez Hilton reports at birth, Faith's body's position restricted blood flow to her arm, resulting in irreversible skin and muscle damage. Mark Lengsfeld, founder of California's Build It Workspace, decided to give her the chance of an arm.

This new prosthetic weighs only a pound and Faith can easily replace it for a bigger model when she outgrows the device, thanks to its insane affordability.

Though heavier prosthetic arms with sensors that connect to muscles can run up to $20,000, Faith's new hand will cost her just $50!"

Pretty cool right?
