Future Engineers hosts online innovation challenges for K-12 students. In 2014, Future Engineers launched its inaugural 3D printing in space challenge, sponsored by the ASME Foundation with technical assistance from NASA, which produced historic achievements including the first student-designed 3D print in space. Based on that success, and through the support of the U.S. Department of Education's SBIR Program, Future Engineers launched a multi-challenge platform in 2018 capable of hosting STEAM challenges of all kinds. All challenges are free for student/classroom participation.
