Four University of Maine seniors created a 3D printed bike frame to donate to Orono High School for their Mechanical Engineering Technology Synthesis (MET) project.

Orono Middle and High School Librarian Emily Jackson Sanborn will accept UMaine Senior and Faculty Framework at 1 p.m. on Monday, May 3 outside the school at 14 Goodridge Drive in Orono. COVID-19 health and safety guidelines will be followed.

MET senior Abdullah Albutayyan, Douglas Bolstridge, Ryan Ehrenberg and Ryan McNeilly developed the polylactic acid (PLA) bike frame using only consumer printers, which produce objects no larger than 5.5 inches in length, width and height. The team had to assemble 85 3D printed parts with 151 bolts and no adhesive to create the frame, which took 764 hours.

Brett Ellis, associate professor of mechanical engineering technology, said the company required 18.4 kilograms of material.

“I’m pretty proud of our students,” says Ellis. “They have come a long way, growing and maturing throughout their fencing project.”

Peter Howorth, an adjunct lecturer in mechanical engineering technology, explains that Jackson Sanborn, the project’s client, requested that the frame be made with a consumer printer to demonstrate to high school students that they too could create advanced 3D prints. goods with easily accessible technology.

UMaine MET seniors designed every component, tested critical components, built the frame, and tested the bike under various load conditions to ensure the bike can be used safely. Based on its over 30 years of manufacturing experience, Howorth claims that all of these tasks would be performed in an industrial environment.

“It has become a great STEM awareness activity between college and school,” Howorth said. “I think (the UMaine seniors) have shown that they are ready for professional careers, and I think they will have exciting ones.”

The cornerstone of the MET program is entrusting teams of seniors with the design, engineering and construction of utility projects for various clients each year.

Ellis says 11 student teams have created a variety of products for customers this year, including low-cost projector systems for UMaine’s Servant Heart Research Collaborative to deliver to students in Sierra Leone, a Mars Rover for the Challenger Learning Center in Bangor, and others.

“For these students to respond as well as they did during COVID (restrictions), it’s been a great year,” Ellis said.
