About the Authors

Joan Horvath is a cofounder of Nonscriptum LLC in Pasadena, California. Nonscriptum consults for educational and scientific users in the areas of 3D printing and maker technologies. She also has an appointment as Core Adjunct faculty for National University’s College of Letters and Sciences. She has taught at the university level in a variety of institutions both in Southern California and online. Prior to that, she held a variety of entrepreneurial positions, including VP of Business Development at a Kickstarter-funded 3D-printer company. Before becoming an entrepreneur, she spent 16 years at the NASA/Caltech Jet Propulsion Laboratory, where she worked in programs including the technology transfer office, the Magellan spacecraft to Venus, and the TOPEX/Poseidon oceanography spacecraft. She holds an undergraduate degree from MIT in Aeronautics and Astronautics and an Engineering master’s degree from UCLA. She is also the author of Mastering 3D Printing (Apress, 2014).

Rich Cameron (known online as “Whosawhatsis”) is Joan’s cofounder at Nonscriptum LLC. Rich is an experienced open source developer who has been a key member of the RepRap 3D-printer development community for many years. His designs include the original spring/lever extruder mechanism, the Reprap Wallace, and the Deezmaker Bukito portable 3D printer. By building and modifying several of the early open source 3D printers to wrestle unprecedented performance out of them, he has become an expert at maximizing the print quality of filament-based printers. When he’s not busy making every aspect of his own 3D printers better, from slicing software to firmware and hardware, he likes to share that knowledge and experience online so that he can help make everyone else’s printers better too.
