Many people have an affinity for disabled animals, but caring for them can be a challenge. Such creatures can require more care and cost, especially those missing limbs. Even though low-cost 3D printers are nearly ubiquitous, not everyone is an engineer or skilled enough to design prosthetics for animals. Fortunately, the University of Nebraska-Lincoln is training a new generation of engineers. Abby Smith, Harrison Grasso, Jaden Schovanec, Rachael Stanek and Alexandra Jensen-students in Biological Systems Engineering (BSEN) 470 and BSEN 480 classes at the university-put to the test much of what they learned to create a prosthetic for a three-legged cat named Olive.
