The studio users incorporate these services intoclass projects, research, and instruction. Scalfani has also recommended the deployment of the3D studio in a visibly open area in their library. Colegrove reported findings from the Universityof Nevada, Reno (UNR)6. He indicated that the services offered by the campus library weresubstantial and cut across numerous disciplines. He reported that cross-disciplinary users quicklyadopted the 3D printing services offered by the UNR library and that the new 3D printers wereoperating at or near capacity during their first year of deployment

Service Learning Experiences are distinguished by being mutually beneficial for bothstudent and community. Service learning is growing rapidly and is considered a part ofexperiential education by its very nature of learning, performing a job within the community,and serious reflection by the student. Service learning involves solving some of society'sissues; such as, homelessness, poverty, lack of quality education, pollution, etc. One of thegoals of service learning is to help students become aware of these issues

The mostrecent U.S. Bureau of Labor projections through 2020 show significant growth of jobs in thescience, technology, engineering, and math (STEM) disciplines. Marra1 et al states thatengineering and science fields will grow at more than 3 times the rate of other disciplines.However, in the midst of the demand, institutions of higher education are faced with thechallenge of retaining students within their engineering programs1-5. Student attrition has beenattributed to several factors including: student attitudes and a sense of belonging in discipline,preparation for the course material, and quality of teaching and compatibility with studentlearning styles1,6-10.
