We experimented with printing electric paint through our paste extruder, into a Fractal Antenna shape recently. Through trial and error, we managed to get it fairly well figured out, and we wrote up our experiences here:
We've spoken a lot about the 3D printing applications possible with the
Discov3ry paste extruder(link go to kickstarter) but there are also some
incredibly cool 2D projects that we want to draw some attention to as well.
Printed electronics is one of these applications.
We got our hands on some Bare Conductive Electric Paint; a water-soluble,
nontoxic and child-friendly material.
The electric paint has a surface resistivity of about...
Our kickstarter campaign has gotten a number of inquiries from Rigidbot users, so I thought I'd reach out here. We're launching a paste extruder that attaches to desktop 3D printers like the rigidbot. It's about the size of a loaf of bread, sits beside your printer, and gives you the ability to print with pastes like silicone, wood filler, gels, icing sugar and a lot more.
+John Mardlin You had me at print Star Wars logo in icing. I opted for Prod batch #1. So, again, I will be curious how long that tubing will accommodate the RB Big. :P Did you guys find a viable 150k reward yet? I saw on the forums that some people were speaking of a dual paste extrusion.
This campaign is ending in 4 hours, we've been blown away by the support we've received for a product(paste extruder), that goes on a product(3D printer), that not that many people have already. Thanks to this amazing community. Disclosure: I'm involved.
Closed source is fine, but I would not recommend trying a patent. Many people have done paste extruders before you and many people will do paste extruders after you. Trying a patent would just piss off everyone, so please take that to heart and avoid being called slime like MakerBot. They have recently started attempting to patent things that others seem to have come up with or is a minor improvement and pissed off many people including myself.
