We are Rabbit Proto, an open source project redefinining 3D printing. Rabbit Proto makes plugins that easily integrate into your 3D printer, enabling it to print complex conductive traces within 3D designs.  Your 3D printer can now print interactive prototypes with capacitive and conductive features.

What is it for?

Designers and makers can now radically speed up their prototyping and ideation process, going from computer design to interactive prototype with just one click.

How does it work?

Rabbit Proto is a print head add-on that easily plugs into your 3D printer, enabling it to print complex conductive traces within your 3D design. The project source code, documentation, and example designs are open source and available on GitHub. Pre-order your Rabbit Proto solution right here.

What can I print with Rabbit Proto?

The possibilities are endless!

Game controllers, wearables devices, and interactive art are just the tip of the iceberg of what is possible.

We’d love to hear about your ideas, sketches, or prototypes, and to feature them on this site!

    An old prototype coming from a student project at the origin of Rabbit. It demonstrates 3D printed conductive circuits embedded within puzzle pieces. More info about that specific project here. Coming up next: demonstrating the workflow from CAD to working prototype. (Source: http://vimeo.com/) InnoEx 3DPrinted Electronic Puzzle from Alexandre Jais on Vimeo.

    While we have focused on extruding conductive material, Rabbit Proto’s functionality can be applied to extrude pretty much anything viscous. Our ultimate vision is to get 3D printers to print *any* material in *any* form, not only plastic, and not only filament.

    Unlike some of the 2D circuit printers out there, Rabbit Proto allows you to effortlessly print circuits inside of the plastic design itself — without having to interrupt the printing process. You can also print circuits on 3d surfaces, and can deposit some pretty complicated conductive patterns while doing it. As just one example, Rabbit [...]

    We’re taking Rabbit Proto through Stanford’s Launchpad this year, and it’s been an amazing journey so far!  We’ll be at the Launchpad beta trade show this next Tuesday, May 6th, between 4 and 5:30pm, on the first floor of Stanford’s design school.  PLEASE JOIN US!

FAQ

Which printer is Rabbit Proto compatible with?

Rabbit Proto is compatible with all RepRap printers having a dual-extrusion board (for example, Rambo, Ramps, etc.). We have successfully installed Rabbit Proto on a Rostock Max and a Mendel Prusa V2. Rabbit Proto could be modified to adapt to other kinds of 3D printers. If you are interested in adapting a Rabbit Proto extruder to your printer, shoot us an email at (info@rabbitproto.com) or post your design on GitHub.

If you are a 3D Printer Manufacturer, please contact us so we can look into making Rabbit Proto compatible with your machine.

What material does Rabbit Proto use?

Anything that can fit inside a 10cc syringe! Our initial focus has been on conductive material and Bare Conductive ink is awesome for printing capacitive touch sensors. We also have done tests with silver filled silicon RTV, which is great in terms of conductivity but also much more expensive.

However you should not be limited by only those two choices! If you want to put chocolate in the syringe and 3D Print your own chocolate factory, do it and (please!) send us some pictures :-)

Is it safe?

Bare Conductive ink is non-toxic and safe for children, their FAQ can give you more information.
PLA is also non-toxic.
Other plastic filaments or conductive pastes might be toxic so be careful with what you print.

What is the electric resistance of the material used?

To get more information about Bare Conductive ink’s properties, please refer to their notes.

Where can I find details to build a Rabbit Proto?

We will post detailed documentation on GitHub and video instructions on YouTube! Also feel free to shoot us an email at info@rabbitproto.com if you have any questions or would like to be added to our mailing list!

Where can I buy a Rabbit Proto?

You can pre-order one from us on this very website! You won’t be charged anything until we are ready to ship you your extruder (around mid June!), so no risk on your side and you will be among the first to witness Rabbit Proto’s awesomeness.

What's so special about 3D printing a circuit?

Unlike some of the 2D circuit printers out there, Rabbit Proto allows you to effortlessly print circuits inside of the plastic design itself — without having to interrupt the printing process. You can also print circuits on 3d surfaces, and can deposit some pretty complicated conductive patterns while doing it.

As just one example, Rabbit Proto can print a first part of a plastic enclosure, then deposit a conductive pattern, and finally finish up printing the rest of the plastic enclosure – all in one printing process. The conductive pattern can be laid out on uneven surfaces just like that! Check out the demo in the video below for another illustration!

An example of 3d printed circuit

How thin can the traces be made? How accurately can they be placed?

The trace is .2 in thickness, and width is 0.84 with the current nozzle. Positioning Accuracy is 50 microns on the Rostock Max prototype, though it will depend on the 3d printer you install rabbit prot o on.
