BOULDER, Colo. — A University of Colorado student needs help to make a difference in the lives of amputees.

Peter “Max” Armstrong created a cheaper and easier way to produce prosthetic.

He’s a finalist in the National Geographic Chasing Genius Challenge. If he gets enough votes, he could win a $25,000 grant.

Five years ago, the 20-year-old created the Go Prosthetic system.

The system uses pre-manufactured sockets in several sizes and a foam to fill any gaps to give each patient the perfect fit.

Armstrong said he would use the money to do more testing and perfect it.

Armstrong said a traditional prosthetic could take weeks or months to create, and his only takes 30 minutes.

He also said a traditional prosthetic could cost patients $3,000 to $5,000. His version would run about $300.

“People who don’t have access to traditional prosthetics, this can be a game changer for them. This can allow people to walk and live normally who really don’t have that chance,” Armstrong said.

The idea started when he was assigned a class project in the eighth grade. Over the years, the assignment has turned into his passion and Armstrong said he’s inspired by all the people it could help.

“Veterans, basically any amputee whether or not they have insurance or whether or not they are covered,” he said.

The voting on the Chasing Genius Challenge website ends Friday.
