No one can deny the power and persistence of a father’s love. Paul McCarthy’s son, Leon, was born without fingers on his left hand due to a complication during gestation. The now twelve-year-old Leon sports a new prostatic hand made by his father with a 3-D printer. Mr. McCarthy is a special effects artist who, realizing the potential of 3-D printing, searched the Internet for two years for blueprints for a new hand for his son. He finally found Iva Owen who had successfully created mechanical fingers for a carpenter and a 5-year-old boy in South Africa. This enabled him to create the hand for his son. The 3-D printed hand cost a fraction of what it would for a traditional prosthetic.
