The report helps its readers to answer questions such as: how much are academic libraries spending on their 3D printers and related peripherals? What kind of equipment are they buying? What is the policy on the technology replacement cycle?  Who is making the decisions on equipment purchases?  Which academic departments are the heaviest users of 3D printing equipment? What percentage of use if for education? For research? For personal use? How much staff time does 3D printing consume? How can staff time be maximized? What are the biggest problems that libraries are encountering in developing and implementing 3D printing programs?  How is equipment being funded? What percentage of funding is grant or gift derived? What percentage of cost is funded through cost recovery charges to end users or service agreements? How are libraries handling the potential environmental hazards of 3D printing? How has the program affected the library's standing on campus? What kind of advice are librarians who have had programs up and running offering to their peers?
