Hey Guys We’ve been playing around with some of the developing dual extruder modifications, and it’s been AWESOME. We’re currently working on a redesign of 1013’s excellent dual extruder mount ([https://forum.lulzbot.com/t/taz-dual-extruder-mod-files/142/1](https://forum.lulzbot.com/t/taz-dual-extruder-mod-files/142/1)). Stay tuned for a drop in dual extruder kit for your printing pleasure. Dual extrusion lets you do all kinds of neat things; two-tone parts are just the beginning. You can print with a secondary support material like HIPS that will dissolve away cleanly. You can mount extruders with different size nozzles; allowing you to print with ultra fine detail on the surface while gobbing the infill in at high speed with a second larger diameter noz. People have even printed rudimentary circuits with dual nozzle setups ([blog.reprap.org/2012/04/some-more-printed-circuitry.html](http://blog.reprap.org/2012/04/some-more-printed-circuitry.html)). Here are a few images of our dual extruder R&D. ![IMG_2301.JPG](https://us1.discourse-cdn.com/flex020/uploads/lulzbot/original/1X/0ba47c8df33e73f8c67abc4ced22ae1fee8df489.jpeg) ![IMG_2299.JPG](https://us1.discourse-cdn.com/flex020/uploads/lulzbot/original/1X/8a64b83fc7c09562af8b6d29ec5300e0986b5456.jpeg) ![IMG_2244.JPG](https://us1.discourse-cdn.com/flex020/uploads/lulzbot/original/1X/26f431ffc7da8d919998f882786b0586c98d011c.jpeg) ![IMG_2319.JPG](https://us1.discourse-cdn.com/flex020/uploads/lulzbot/original/1X/95be6178e4fdb1882269395e2f6739da3c0d6ce0.jpeg) What will you use dual extrusion for?
