3-D Printers for Libraries

As the maker movement continues to grow and 3-D printers become more affordable, an expanding group of hobbyists is keen to explore this new technology. In the time-honored tradition of introducing new technologies, many libraries are considering purchasing a 3-D printer. Jason Griffey, an early enthusiast of 3-D printing, has researched the marketplace and seen several systems first hand at the Consumer Electronics Show. In this report he introduces readers to the 3-D printing marketplace, covering such topics as:

• How fused deposition modeling (FDM) printing work
• Basic terminology such as build plate, spool, nozzle hot end, direct extruder, and Bowden extruder
• Plastics used, such as ABS, PLA, and others
• Descriptions, price ranges, and filament specs for 3-D printers from MakerBot, Printrbot, Solidoodle, and other manufacturers
• Suggested staff skills for performing basic maintenance tasks
• Where to find both ready-to-use designs and the software for customizing, from beginning to advanced systems
