We welcomed Joan Horvath back to the show to discuss 3D printing with her company Deezmaker & 3D printing for space and here on Earth. For more information, visit her company website, http://deezmaker.com. During the first segment of our 1 hour 27 minute show, Ms. Horvath introduced us to 3D printing and Deezmaker in Pasadena, CA. Joan talked about being part of the Maker and Hacker communities, the two highly successful Deezmaker Kickstarter programs, and their two small desktop and portable printers, the Bukobot and the Bukito Portable Printer. She described their customer as being one of 3 types. Their target included high school and college students. We talked about the capabilities of their printers, the fact they both are do it yourself assembly kits, and that the company offers some assistance in assembly as well as scanning. Other topics in this segment included mass manufacturing, molds, robotics, mechanical parts, materials used to build the kits as well as for printing items. Joan was asked about plans to put a 3D printer on the ISS, the success of both Kickstarter programs, the interest & demand for 3D printing, Deezmaker competition, and even lunar surface 3D printing. We learned that tops among the challenges her company printers faced were supply chain problems. I asked if Deezmaker faced ITAR challenges which it does not. Joan often referred to their printers as a "little factory on the desk." Jack emailed asking if these smaller printers were stepping stones to learning how to work with larger 3D printers. Joan talked about the operating software & computer tools, including G Code which 3D printers use. She also relayed a story to us about how these printers served as a learning inspirational tool for geometry/math students and others. Rob of PISCES called in from Hawaii to ask about 3D printing and volcanic basalt. In the second segment, Aaron wanted to know if the 3D printing claims were exaggerated. Joan said the industry was definitely on the ramp of the hype cycle. She then said what she thought 3D printing would be good for and not so good for. The latter group included food. She then discussed uses in archaeology, paleontology, and other fields. Our guest was asked more about lunar 3D printing. She said it would be OK for 1 or 2 things, not for mass production copies of something needed. Ben talked about industry consolidation. Joan thought it might still be too early to see widespread consolidation. Doug called to say he was skeptical about 3D printing & asked supply chain questions and questions about trades and analysis. Joan mentioned an upcoming Burbank, CA expo, the Deezmaker blog on the website, a calendar of events and more. As we ended our discussion, we talked about international 3D printing interests, materials, garage invention tinkering with 3D printing, and the Deezmaker open house the first Sunday of every month in Pasadena.
