A couple of months ago we talked about the Rabbit Proto, an add-on that lets existing 3D printers print with conductive ink and other viscous materials. Structur3D’s Discov3ry extruder is like Rabbit Proto, but it’s designed to be more versatile from the get go.
Discov3ry works with “any stepper motor based, fused deposition modeling (FDM) desktop 3D printer system.” All you have to do is switch out a printer’s printing tip with Discov3ry’s feed tube and extruder tip, then connect Discov3ry’s wiring to the printer. Now you can print with even more kinds of materials, including icing, ceramics, polyurethane, silicone and yes, conductive ink.
The Discov3ry will come with reusable food-grade syringes, tubing, connectors and tips to help you get started. Because printing parameters will have to be adjusted depending on the material you want to use, Structur3d will also provide documentation as well as setup a forum for users to exchange tips on using the extruder with different materials.
Pledge about $275 (USD) on Kickstarter to get a Discov3ry extruder as a reward. With your help, someday Structur3d will be able to afford the letter “E.”
