How many start-up CEO’s do you know that host a podcast? Not many, for sure. As of today you can add Bre Pettis, the CEO and co-founder of Makerbot Industries to that short but illustrious list of podcasting CEOs.
In the inaugural episode of the new MakerBot Explorers podcast, Bre interacts with Corey Renner, Tom Burtonwood, and Thomas Lipoma to find out what they’ve been doing and creating with their Makerbot 3D printers.
Thanks to the Make: Robot Hacks series, hosted by Mike Senese, you can get an inside perspective on the development, trials and tribulations, and performance of Gael Langevin’s unique InMoov Open Source 3D printed humanoid robot.

Makerbot and America Makes jointly announced “Makerbot Academy”, a new initiative to support and strengthen American schools and STEM education. A big part of the initiative centres around giving students access to technology to foster interest, curiosity, and enthusiasm in STEM.
The new Makerbot Academy, with support from donors, plans to place thousands of 3D printers in schools across the nation. Here’s the opening text of the announcement:
We’re proud to announce MakerBot Academy, an educational mission to put a MakerBot® Desktop 3D Printer in every school in the United States of America.
The first MakerBot Academy initiative includes 3D printing bundles for classrooms, an awesome Thingiverse Challenge, and generous support from individuals and organizations.
What You Can Do
1. Get the word out. Tell the teachers you know to register at DonorsChoose.org.
2. Support a school. Contribute to the effort by choosing a teacher; help get them set for the Next Industrial Revolution.
3. Participate in the Thingiverse Challenge. Develop models that teachers can use to improve Science, Technology, Engineering, and Mathematics (STEM) education.
Responding to a Presidential Call to Action
At this year’s State Of The Union address, President Obama announced a new initiative to bring manufacturing jobs back to the US. He affirmed, “3D printing has the potential to revolutionize the way we make almost everything. The next industrial revolution in manufacturing will happen in America.”
We’re inspired by the President’s commitment to keep America at the forefront of the Next Industrial Revolution and we’re eager to do our part to educate the next generation of innovative makers who will keep our economy strong.
Let’s Get MakerBot Desktop 3D Printers into American Schools
Together with America Makes, and by leveraging the crowdfunding power of DonorsChoose.org, we’re launching our first MakerBot Academy initiative: Get thousands of MakerBot® Replicator® 2 Desktop 3D Printers into K-12 public school classrooms across the country — by December 31, 2013!
This Kickstarter project uses an innovative approach to produce 3D printed circuit boards on a wide range of different substrate materials.
It won’t meet everyone’s needs, and the long term reliability of the circuits it produces is still to be established, but if you do a lot of circuit board prototyping or want to explore more exotic applications like wearable electronics, this project might be just the ticket.
No etching, no harsh chemicals, and almost zero lead-time. Just print out your circuit board design using the two-pass system and you’re ready to install the components and test.
Want to get involved with 3D printing but don't have a big enough budget to buy even one of the current low-cost machines? If you aren't particular about the print quality or size, and don't mind waiting quite a while for delivery, then you might find the Peachy Printer Kickstarter project just what you've been looking for.
The design approach is minimalist, to say the least, and was originally hacked together using parts that Rylan Grayston happened to have laying around on his workbench. It looks very much like a school science project - which I'm not negative or being critical about. Actually I admire his ingenuity and creativity quite a bit.
Rylan, with some help and assistance from his local hackerspace, managed to put together a resin based 3D printer that actually produces parts of surprising quality - surprising given the total lack of precision mechanical drives or other commonly used techniques. Instead of using a z-axis drive mechanism, Rylan decided to keep the build platform stationary while slowly increasing the resin level, drop by drop. By counting the number of drops that fall in the build container, and knowing the container dimensions, his application calculates the current resin level and drives the resin curing laser accordingly.
He eliminated the need for a dedicated micro controller and other electronics by using the audio headphone and microphone jacks on his PC. Of course, this approach is marginally robust and requires that you don't use your PC for anything else while printing - but it does work, which is brilliant.
At first I was a bit concerned that The Peachy Printer Kickstarter project might be a scam, but after watching the introductory video and looking at the associated photos, I decided that it's probably real. In any case the cost is extremely low - basically CAN$100 for one of the Peachy Printer kits.
As I mentioned above, if you do decide to back the project be prepared to wait a while. Most of the reward options have dates in the Fall of 2014 - about a year out at this point in time.
How's Rylan doing so far? Pretty good actually. The initial project funding goal was CAN$50,000, which he needed to improve some of the design and to order parts for the printers. As of October 12th, with 8 more days left to go, he has totally blown away the goal and clocked up CAN$591,450 all ready.
Spent an interesting afternoon with Roland working with his brand new MakerBot Replicator 2X 3D printer. The printer arrived while I was in the States at the World Maker Faire, and Roland had been able to make a lot of progress - more than I expected.
He had unpacked, setup, and adjusted the printer, and was cranking out lots of sample parts including some that he downloaded from Thingiverse. Today's session was primarily Q&A - talking about his toolchain, processes, and design trade-offs.
It turns out that the MakerBot documentation is fairly light on some details - so he didn't realize the necessity of cleaning the build platform regularly, typically with acetone and alcohol. The documentation is also written from the perspective of a U.S. user and makes lots of assumptions that aren't valid for overseas users - like the ready availability of 3M blue tape at local hardware stores.
The biggest issue we ran into was that the left extruder wasn't working properly. After a little inspection we noticed that the knurled shaft was incorrectly aligned and wasn't grabbing the filament, as you can see in this photo:
Disassembling the extruder, we were able to realign the shaft so that it worked properly, at least for the first print:
After we buttoned everything up again, Roland was able to print using both of the heads for the first time.
Unfortunately the left extruder started acting up with the next print and will require more debugging/trouble-shooting. It's almost as if there is a missing spacer or spring.
