By far the most important component to an FFF or FDM-based 3D printer is that of the extrusion system. A faulty extruder can make a quality 3D printer, a worthless piece of junk.

X-truder, Dual Nozzle 3D Printer Head Assembly
Finally, a print head worth buying!
What is it?
A high temperature, dual nozzle, single motor, compact, affordable, light weight, professional 3D print head. We’ve integrated all the best functionality, in a small package weighing about 16 ounces.
Why is it?
We wanted a print head capable of high temperatures and running materials such as ABS, PC, PVA, PLA, TPU, etc. Along the way, our wishlist grew to include dual hotends, nozzle retraction, simplified wiring, LED lighting, compact size, low cost, etc. We weren’t interested in what was available in the marketplace, so we created it.
