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.

We welcomed Dr. Haym Benaroya, mechanical and aerospace engineer at Rutgers University, back to the show to discuss lunar thermal and seismic analysis, space policy, human spaceflight, Mars, and more.  Our intention was to do a one hour program but due to incoming listener phone calls, this program lasted for 1 hour 39 minutes without a break!  In addition, the discussion at times with callers was quite heated, very passionate and ripe with disagreement, especially between callers and myself.  Frankly, there were times I just had enough of the gloom and doom and the la la land fantasy stuff so I blasted back on what the callers more than the guest were saying.  We started the program with an update from Dr. Benaroya on thermal and seismic analysis of lunar data collected from sensors left on the Moon by the Apollo missions.  The data has been run through new models for up to date processing.  As it turns out, for seismic activity, an igloo like structure which Dr. Benaroya described is probably the best for the habitat. Also, he said only flimsy items such as an antenna would like be risky structures due to lunar seismic activity.  I asked him to compare lunar seismic activity to the seismic activity of California and Japan.  We have it much worse here on Earth!  We talked about radiation issues & Haym suggested about 10 feet of regolith on the top of the hab would probably be OK other than for a solar event.  He also said much more data was needed for actual lunar structural engineering.  I asked him what the first lunar settlers would do during their day and this took us to HSF to Mars issues, microgravity concerns, and the Moon as a stepping stone to Mars.  John Hunt was the first of the callers, focusing on policy with the politicians.  Haym talked 3D printing with him, then I asked John if the program he was describing could be done in 10 years.  After forcing him to provide us with a yes no answer, he said no. Haym said the same but both agreed technology was not the problem, leadership was the problem.  We talked the need for profits for private ventures and opened up public/private partnerships for discussion on the show.  I asked both how to start implementing their plans & that was the opening salvo of the fireworks that unfolded for the rest of the show.  Doug called next and talked about his ideas for what astronauts on the Moon would do and his lunar development ideas.  I then challenged both caller and guest to outline their steps for making their happen.  I thought their implementation plans were severely lacking and opened up on each of them but more so on Doug for the balance of his call.  Haym said the first step was to rebuild U.S. launch capabilities. Doug had a different first step & talked about government funding as in a private/public partnership similar to what SpaceX has with NASA for Falcon.  I asked Dough how he intended to sell the importance & value of the program he suggested to those controlling policy and funding.  See what you think of this discussion & post your comments on our blog.  After Doug cleared the line, Charles Pooley called in & at one time I said he was the longest playing broken record in Space Show history! I told him he was full of doom and gloom and other people see things differently and I did not want is view of things to be right or prevail, suggesting others see things differently than he does. Again, your comments are welcome.  Near the end, I simply was rejecting the “dismal situation” facing our space program. While Haym agreed that things were not good today, he talked about how he inspires and works with his students so they can create a positive space environment during their careers and for our future.  Just before the show ended, Tim called at the last minute and I promised to send him a Timex given his rotten sense of timing show after show. With Tim, we talked propulsion, Zubrin’s thoughts on going to the Moon, & the two private Mars missions on the drawing board.  In his concluding remarks, Haym explained why he was not supportive of either Inspiration Mars or Mars One.
