Research Evidence
Aim: To investigate the impact of integrating fused filament fabrication 3D printing into CAD education on learning speed and comprehension.
Method: Comparative study
Procedure: Students were divided into groups, with one group receiving traditional CAD instruction and the other receiving instruction that integrated hands-on 3D printing of their designs. Learning outcomes, task completion times, and comprehension levels were measured for both groups.
Context: CAD education and additive manufacturing integration
Design Principle
Tangible prototyping enhances conceptual understanding and design iteration speed.
How to Apply
When teaching or learning CAD, use a low-cost fused filament fabrication printer to create physical models of designs as they are being developed.
Limitations
