Forexample James Nasmyth’s [1] definition of engineering as “common senseapplication of materials” reflects the knowledge and technology, exclusive tomechanical elements, prevailed at that time. Makers are individuals who design andbuild new devices and share their experiences with others. Universities provideopportunities to wake up the dormant geniuses of such individuals among studentswho sometimes may not be turned-on by the traditional classroom teaching. But tomake full exploitation of their geniuses they have to have a comprehensiveknowledge of the prevailing technologies. This paper describes the method by whichknowledge of

In January 2002, The National Science Foundation chartered a workshop on“Redefining Mechanical Engineering” to explore new possibilities for ME education.Recommendations were made to streamline and update ME curricula by introducing emergingknowledge related to micro/nano technology, product design and realization and etc. andexposing students to computational methods and design practices employed by practicingengineers [2].

In addition, students often say, “Our friends in artsand management have fun and still get A grades, why do we have to work so hard to getgood grades in engineering?” In other words, some students feel that the faculty sets thebar too high in engineering, and therefore the grade does not always reflect the hard workthey put into the learning process.

After further reflection and discussionwith the faculty mentors, the students realized that the specified clearances were less than the.012” minimum layer thickness of the Dimension machine. In slicing the STL into individualcross sections, the slight difference was not captured as in effect it “rounded up” and printedanother .012” layer when only a fraction of that thickness was specified by the CAD file. Thiswas remedied by using a deburring knife and razor to slightly trim the guide slots until the panelwas able to slide in with reasonable effort.A second challenge
