Congrats to Stillwater Area High School junior Everett Kroll who won first place in the Intel International Science and Engineering Fair. Kroll, along with SAHS junior Haley Jostes were among 1,800 high school students from 75 countries participated in the world's largest international pre-college science competition which was held in Pittsburgh last week. Kroll earned First Award in biomedical engineering for his project to create a prosthetic foot that can be made inexpensively on a 3D printer. The award netted him $3,000. Jostes was named a Scholar of Distinction by the National Junior Science and Humanities Symposium.

In addition, Kroll was also one of two students featured on a segment during the NPR radio program “Science Friday.” During the segment, Kroll talked about creating 54 different iterations of his project (so far) as he labors to create a workable design.

“It’s just surprising how much engineering goes into something that looks so simple, but really is extremely complicated,” Kroll said. “Like with my [prosthetic] foot, there’s no moving parts, there’s no electricity, there’s no motor or nothing like that. It seems very simple, it’s just a shape that kind of looks like a foot, but you have to do more by multivariable calculus, and linear algebra, and just run calculations, and all these different crossroads of very complex principles and engineering goals and situations—and a simple problem becomes a lot more difficult. It’s just one shape, a solid shape, and it took me over 20 months to make.

Kroll said he first became interested in 3D printing working in the makerspace at SAHS. He plans to continue to refine the prosthetic, working up the leg, knee and transfemoral amputation.
