RAPID PROTOTYPING IN THE DESIGN METHODOLOGY

Abstract

The main objective of a design course is to teach a procedure to practice the fundamental engineering knowledge as repeatable design techniques. A popular approach to teach undergraduate engineering design is by solving open ended design problems. Tools are available now to students allowing them to evaluate the cost, manufacturing, usability, and environmental consequences of their designs. However aesthetical success of the design can only be verified subjectively and cannot be imagined from 2D drawings or 3D models. Observing and touching the products prototype may help overcome this obstacle. Rapid prototyping (RP) techniques allow creation of prototypes in short amount of time. RP enables realization of a design and promotes the enthusiasm and motivation in students. This paper describes the visualization of the design ideas and the position of the RP in the design methodology.

1. Introduction

Design as activity involves creativity and innovation but it is constrained by high quality and low cost to meet customer expectations. Customers are increasingly demanding both innovation and value. Methodological design courses exist in engineering education with the objective of teaching engineering design fundamentals. A popular approach to teach undergraduate engineering design is through a structured, problem solving method that students use to tackle open-ended design problems1-4. Classical engineering design process5 has the following general steps, 1) Recognition of need 2) Definition of Problem, 3) Synthesis, 4) Analysis & Optimization, 5) Evaluation, 6) Presentation. The native language of design has evolved from the technical drawing to a 3D model. Ability to visualize the ideas and communication among design teams are possible with visual-spatial perception of the design concepts. The visualization of technical artifacts started with scratched stone tablets, continued freehand sketches on papyrus or paper and with digital age and CAD it has advanced to another level6. Solid models provide the ability for easy modification and enable structural/thermal analysis and simulations. Another advantage is that the traditional tasks of a designer, drafter, analyst, and prototype maker may be all performed by a single engineer using digital engineering design tools. Digital 3-D models can be easily shared and accessed through web-based tools on the internet, which provide a collaborative design environment for geographically distributed design teams7. Next step for design visualization and verification is Rapid Prototyping (RP), which started a few years ago but stumbled because of the large capital investments required and hidden expenses for the consumables8.
