Kansas Teenager Uses 3D Printer to Create Prosthetic Hand for Boy

Seventeen-year-old Mason Wilde of Kansas used the 3D printer in the Johnson County Library to create a prosthetic hand for nine-year old Matthew, who was born with only a thumb on his right hand. Matthew's condition - referred to as a limb difference - occurs for unknown reasons in about 5 out of every 10,000 births, and affects hands, arms, legs, and toes. Wilde modified Robohand plans available online to make a device that would fit the boy's small hand. The library keeps its 3D printer in an area called the Makerspace that recently opened.
