The aim of the study is to develop and evaluate a prototype designer feedback tool to give
manufacturability feedback information to design engineers early at the conceptual design stage. Providing
design engineers early manufacturability information on their designs helps them to improve manufacturing
quality of their designs thus reducing the overall cost and lead time to manufacture. The Three Dimensional
Integrated Feedback (3DIF) system is designed to be a manufacturing visualization feedback tool that is
generalizable, automated, usable, inexpensive and portable. Feedback given to design engineers can be in
various modalities, including verbal, text, 2D drawings, or 3D. Information abstraction and modality
significantly affect its interpretation, so it is important that feedback given to the design engineers should
be in the language understandable to them and is able to convey necessary information with minimal
interpretation. An experiment has been designed to evaluate performance and workload differences
between expert and novice design engineers when they conduct design tasks in feedback modalities.. The
preliminary results from the study show that providing feedback in 3D improves the manufacturing quality
of the end design with lower overall cognitive workload.
