Delaware RepRap Prusa i3 Mendel Build Class

9286503929_b62a5d4fba_o

Our friend John Abella (of the Maker Faire 3D Printer Village and Delaware Makerspace Barrel of Makers) is running a two-day RepRap build workshop in Wilmington Delaware, October 5th and 6th.   Attendees will be building Prusa i3 printers with all top-shelf parts:  milled frames from Josef Prusa, genuine J-head hotends from Hotends.com, stainless threaded rods and hardened chromed smooth rods.

The workshop is being held at the Wilmington DoubleTree Hotel, and will have catered food for attendees.   Every person attending will leave with tools and basic supplies to maintain their printer and get started printing.   The workshop fee – all inclusive –  is $999.

FREE EVENT THIS THURSDAY: Through the Looking Glass

This Thursday, please join us at a FREE exhibition of the work of Cornelius Varley (1800-1860) put on by the venerable American Philosophical Society. It is a fantastic exploration of the life work of this fellow tinkerer and inventor who’s insight and explorations reminds me a lot of our Hive76 members!

A few of us will also be presenting at this event! We will have live 3D sugar glass printing, exhibitions of Brendan’s boom cases, Dan’s 8 mm RockBox, PJ’s electronics, Corrie’s textiles and artwork, Chris Terrell’s wood burning, and maybe a few more things.

We hope to see you there! Deets and directions below.

Getting Raspberry Pi to control your 3D Printer

We got some Raspberry Pis and began jumping through some tutorials. Adafruit has a particularly thorough and easy to follow series. We’ve had good luck with the Raspbian Wheezy distro and it works just like familiar Ubuntu since it’s based on Debian. Remember to run:
sudo apt-get update
sudo apt-get upgrade

upon first launch. That will make things a lot easier since the release is rather old by now.

I got some time to explore the Raspbian distro.

RaspberryPi-jmil

After seeing all of my efforts, Morfin couldn’t wait to give it a shot.

RaspberryPi-Morfin

Eventually we got my favorite light-weight print controller github.com/kliment/printrun running an active 3D print. It really was incredible to have a $40 computer connected to the interwebs and sending gcode with a full GUI over python->USB-serial. It’s a bit too slow for computational slicing, but would probably be GREAT for a bot-farm. Note that you should also use pianobar instead of full-blown pithos for pandora audio. Note that the audio worked great after we ran the apt-get upgrades mentioned above.

RaspberryPi-Desktop

And remember to grab our desktop background! It’s only 1.2 MB.

ShopBot as a 3D Printer: controlled by a RepRap RAMBo

suggested by Kliment via IRC (/ht), the way to have a heavy toolhead moving about in 3D with high speed AND precision is to modify a ShopBot instead of a Rostock. Recall, the Darwin suffered this design challenge which led to the Mendel.

With RAMBo bypassing the stock motherboard we can drive the ShopBot to scary speeds (10x faster in XY and 100x faster in Z.). Precision should also be ~10x better than belt-driven motion, but needs more fine tuning.

and did i mention it was freaking awesome?

My ShopBot RAMBo Marlin firmware branch is available via GitHub (of course). Follow along in the GitHub log to understand our process.

Thanks to ShopBot and Ultimachine for all your help and schematics!!

Illustrator to OpenSCAD to 3D printing

For Philly Tech Week, I will be showing visitors how to take a shape from Adobe Illustrator into the popular open source CAD program OpenSCAD and make a 3D model suitable for 3D printing.

Draw in Illustrator, extruded in OpenSCAD

I’m sure you know Illustrator. It’s the most successful vector drawing program <clarkson>in the world.</clarkson> OpenSCAD is less well known. It is best described as coding for objects. You make a solid with the function cube() and cut a cylinder() out of it with the difference() function, etc. But sometimes you want a more organic or complicated shape to start with. That’s where artist JK Keller stepped in and made a script that automates some of the process for you. What you need for this workshop:

There may not be time to print everyone’s design, but you should go home with something 3D printed.

Monday 4/22 5pm – 10
Gratis and Libre (free)

Why I’m Registered to be an Organ Donor

TEDxYouth@SanDiego Logo

The critical shortage of organ donors in our healthcare system is the reason I’m registered to be an organ donor and motivates my research to develop suitable replacement technologies in the field of regenerative medicine. Video below! It was an honor and privilege to take part in TEDxYouth@SanDiego, which brought 400 San Diego high school students together to interact and think deeply about the future. It was incredible to speak with so many students who are truly the Architects of the Future.

From TEDxYouth@SanDiego:

Using simple yet illustrative analogies to help non-scientists understand his scientific discovery process, Biomedical Researcher Jordan Miller explains to his young audience how he developed vascular structures through 3-D printing. This exciting research is an important complement to advances medical researchers have made in 3-D printing bioidentical human tissue and organs in the lab. it’s a remarkable prospect for the future of organ transplantation.

Deriving inspiration from a cross section of bread and the sugar structure arcing over his dessert, Dr. Miller describes how he combined his background in regenerative medicine, a passion for the maker movement and reliance on worldwide open sourcing to develop viable 3-D printed vascular systems that he demonstrates actually transporting blood.

Jordan Miller, Ph.D. is a post-doctoral researcher in the Tissue Microfabrication Laboratory at the University of Pennsylvania. Involved with the 3-D maker community since its infancy, Jordan uses a 3-D printer in his work in biomedical research and regenerative medicine and credits open-source collaboration and the maker movement as important contributors to the success of his research.

Leaders of the 3D Printing Revolution

The Creator’s Project released a new video, and our sugar printing, gelation, and blood pumping was featured in it! Trackback is to 3Ders.org The project goal is to unify artists and technologists and this video is focused on 3D Printing:

And I just got done with a talk at ScienceOnTap Philly! It was a truly excellent night! Special thanks to the Organizers and also the Hivers who came out or emailed in their support! You peeps are the best.

Here are some pics via the Twittersphere. Thanks to the photographers for posting!

Open Source is a Philosophy, Not a Checkbox

I just got back from the 2012 Open Science Summit which took place in Mountain View, CA. It was an excellent meeting and a great opportunity to meet others using open tools and ideas to forward Science! Check out the list of talks and you can also access videos of all of the talks. And you can also read more about the speakers.

I gave a talk too where I delved deeper into the science behind our work with RepRap for research in Regenerative Medicine and I made the case that open source is a philosophy, not a checkbox. Try not to get caught up in semantics of open vs. not-open (e.g. one could try to label Arduino as not an “open” platform since it has proprietary Atmel chips on the board). Instead, try to think of open projects as those in which you see people as collaborators (“open”), not customers (“closed”). We all have many things we can learn from each other, and who doesn’t want more collaborators to learn science together? Some interesting Q&A at the end too.

Tonight at IndyHall: Cory Doctorow book reading and 3D printed sugar

We are cosponsoring Cory’s Pirate Cinema event at IndyHall tonight, but since there’s not much for Hive76 to do, we decided to make him a present. Here’s a video of production last night:

That’s a 3D printed sugar head! Cory’s excited to see it in person. You should be too! Come to IndyHall 22N 3rd at 7pm tonight. Here’s the Anyvite link to RSVP. We’ll be bringing a boomcase for the PA too.

The gritty details: That’s a Baricuda extruder using air pressure to extrude molten sugar. Now I need to figure out how he can get it home to the UK in one piece.

Hive76 @ Maker Faire NYC 2012

Hive76 sure made the rounds at this year’s Maker Faire. With 2 tables in the 3D Printing Village, we had a steady stream of visitors both

eagleApex being interviewed

days, ranging from Chocolateers, Digital Artists, to young children asking about 3D printing toys and parts for their projects. Discussion started about 10 minutes after we left Maker Faire for what to do next year. Check out the album for some quick snapshots of this year’s events including Karaoke, Thumb Wrestling, and of course, the occasional interview.
