3Dx2014 – Erin RobotGrrl #3DThursday #3DPrinting

We invited a handful of members of the 3D printing community that we have been featuring for #3DThursday or on our weekly 3D Hangouts live show to share with us their thoughts about the past year, what they each shared, and what they are looking forward to for 2015.

Erin RobotGrrl makes robots!

She had this to say:

Was out for a week with a cold over the break. Thanks for the offer to include it again. Hope it is all going awesome there. Can’t wait for the next episode of Circuit Playground!

Here is some of her recent work, shared at Maker Faire Ottawa 2014:


  1. Soft robotics toolkit
  2. Graphene filament created in a home lab
  3. Computational Design of Linkage-Based Characters


An Automatic Food Slicer robot that used a 3d printed chassis, augmented reality, and a gesture sensor. It was able to slice play doh.

Flexineocube – two flexible circuit boards that fold together to create a cube that uses neopixels. We improved some methods of 3d printing an etch-resist onto flexible circuit board material (Pyralux).


I’m looking forward to when someone creates a new 3D printer that uses two robotic arms to simultaneously extrude filament and glue. The arms would not be limited to a single axis of movement, so prints could be fabricated in a manner that is better than the usual bottom-top approach. There would also be swappable tool heads, for polishing, sanding, or micro-subtraction like drilling small holes.

(ED NOTE: and now that is what *I* am most looking forward to! Wow!)

Thanks for sharing your thoughts with us!

Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!

Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!

The Adafruit Learning System has dozens of great tools to get you well on your way to creating incredible works of engineering, interactive art, and design with your 3D printer! We also offer the LulzBot TAZ – Open source 3D Printer and the Printrbot Simple Metal 3D Printer in our store. If you’ve made a cool project that combines 3D printing and electronics, be sure to let us know, and we’ll feature it here!

Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
