Method & Evidence

AimHow can integrating 3D printing with CAD assignments be used as a scalable instructional method to introduce engineering students to design and manufacturing processes?
MethodCase Study / Educational Intervention
ProcedureA two-phase approach was implemented in a first-year engineering design course. The first phase involved instruction on technical content, including CAD software (Autodesk Inventor) through five assignments covering part, assembly, and drawing files. The second phase involved a hands-on design project where student teams applied this knowledge. A key enhancement was the integration of consumer-grade 3D printers, requiring each student to print their CAD designs.
Sample1200+ students per year
ContextFirst-year engineering education at a large research university.

Variables

IVIntegration of 3D printing with CAD assignments.
DVStudent understanding of design and manufacturing processes.
CVFirst-year engineering curriculum, team-based projects, CAD software used.

Strengths & Limitations

Strengths

  • +Scalability for large student cohorts.
  • +Direct, tangible connection between digital and physical design.

Limitations

The quality and accuracy of 3D prints can vary, and not all designs are suitable for immediate 3D printing without modification.

Reliability & validity

The study's validity is supported by its application to a large number of students over time. Reliability could be further enhanced by standardizing the complexity of CAD assignments and the 3D printing parameters across all student groups.

Think critically

Consider the limitations of consumer-grade 3D printing and how they might affect the perceived success of the design-to-manufacturing link.
