Related Technical Papers More than 100 SME Technical Papers cover additive manu- facturing topics, including TP13PUB82, which describes three open-source machines built or redesigned at Robert Morris University (Moon Twp, PA; www.sems.rmu.edu/engineering)— two based on fused filament fabrication (FFF) and digital light processing (DLP) technologies, and another on the modification of a numerically controlled (NC) router into an extruder based on FFF. The project costs varied within a range of $200–$1000, and future work will include experimenting with additional bio- logically friendly materials for biomedical engineering and with composite materials for various applications.
