Rapid Prototyping in an Electromechanical Engineering Technology Program

Abstract :

 
Fused deposition modeling (FDM) is one of many prototyping techniques available today for
building three-dimensional tangible models of mechanical parts for use during the design
process. In the senior capstone course for electromechanical engineering technology (EMET)
students at Penn State Altoona, a FDM system is used to create part concepts and test them for fit
and function. The FDM ABS components are also often incorporated in completed design
projects, as functional and aesthetic elements. But the FDM has much broader applications
throughout the program and across the campus, as the centerpiece of a unique partnership
between art and engineering faculty. “CAD for Artists”, an introductory level art course that
includes the use of the FDM machine, is taught concurrently with the capstone design course.
Ongoing faculty research in conjunction with the FDM machine provides invaluable “real world”
models for the students. In addition to the use of rapid prototyping technology among
undergraduate students, and for faculty research, outreach occurs each spring in the form of a
program for several dozen middle school (11-13 year old) female students from south-central
Pennsylvania, with an interest in science and engineering. In teams, the students design their own
consumer product and use the FDM to make the parts, which the students can handle and
discuss.
The paper describes
• the history of the collaboration between art and engineering faculty;
• experiences with EMET students and their use of the design tool;
• observations of the impact of the FDM outreach effort;
• operation, benefits and limitations of the FDM;
• interesting senior project applications;
• mechanical properties of FDM ABS copolymer; and
• planned future directions for the design collaboration.
