A 10-year-old's 3D print shop is buying mom a house

Ernesto Gael Hernandez, 10, runs a 3D printing operation out of his home in Brownsville, Texas, with three printers going at once and roughly $1,500 in profit so far. The business, Prestige 3D Labs, started a few months ago when he asked his mom for a printer. She told him to save his chore money instead. After $500 in chores, he bought the first machine and taught himself custom design from YouTube tutorials.
