of the final project and feedback for revision and improvement within the design process(Alley, 1961). In an educational setting, models and prototypes have traditionally beenconstructed by hand using a variety of materials in the absence of machining tools and training.This is considered a fundamental aspect of design according to the Standards of TechnologicalLiteracy set by the International Technology Education Association (ITEA, 2002), the NationalAcademy of Engineering (NAE, 2002), and many leading engineering educators (Oaks, 2003). In the 1980’s, the manufacturing industry began developing what has evolved into rapidprototyping and three-dimensional printing technology. This technology has provided the abilityfor designers and

traditional problem-based learning format, as after the stated Challengeand following the Generate Ideas activity, students examine selected thoughts from experts thatrelate to the problem and direct their thoughts in the desired direction(s) before engaging in“Research and Revise” activities. These steps are supported by additional research that hasdemonstrated improved learning when students first generate their own ideas and then hearexperts’ ideas prior to consulting resources or learning new material.18 Formative assessment orfeedback is useful to students and instructors as well in generating actual learning19 and isincorporated in the Legacy Cycle at the Test Your Mettle stage. Lastly, students are motivatedby creating a product or answering
