Boy gets new 3D printed hand
A boy without fingers on one of his hands has had them replaced - by 3D printing new ones.
12-year-old Leon was born without fingers on one of his hands.
Artificial replacements can be extremely expensive so Leon's dad started looking for an alternative option.
He came across a website with instructions on how to use a 3D printer to make his son a functioning hand.
Now Leon can use it to write, draw pictures and it really has made a huge difference.
