Joan Horvath and Rich Cameron

Joan Horvath and Rich Cameron are the cofounders of Nonscriptum LLC based in Pasadena, California. Nonscriptum consults for educational and scientific users in the areas of 3D printing and maker technologies. Joan and Rich are particularly interested in finding ways to use maker tech to make scientific research cheaper and more accessible to the public.


They have written five books for Apress between them:  Mastering 3D Printing (2014), The New Shop Class: Getting Started with 3D Printing, Arduino, and Wearable Tech (2015), 3D Printing with MatterControl (2015),  3D Printed Science Projects (2016) and Practical Fashion Tech (October 2016). They also teach online classes in 3D printing and maker tech for LERN Network’s U Got Class continuing education program. Links for all of the above are on their website, www.nonscriptum.com.

In addition to her work with Rich, Joan 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. Before she and Rich started Nonscriptum, she held a variety of entrepreneurial positions, including VP of Business Development at a Kickstarter-funded 3D-printer company. Joan started her career with 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 a master’s degree in Engineering from UCLA.

Rich (known online as “Whosawhatsis”) 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 used on many 3D printers, 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.
