Here’s what i think about the very affordable Aluhotend! Plus, there’s a chance for you to win one at http://www.youtube.com/watch?v=Fv7Gkp8-Mh8&t=8m57s

Those look like the exact same nozzle that QU-BD supplies us.
@Chuck_A thanks for reminding me, i knew i had forgotten something there. Will have it on Youmagine in a second!
The hotend was of course PID tuned and had a very stable temperature throughout the print. Feed rates were at a very normal 60 to 70mm/s, and both hotends have an 0.4mm nozzle.
If I started tuning extrusion widths and multipliers, I’d start influencing all kind of other parameters about the result as well, like layer adhesion, and I wanted the result to be (at least mechanically) as comparable as possible.
@ThantiK I would think it’s the other way around. The Aluhotend is made by a respected member of the RepRap community who also happens to be a forum admin. http://reprap.org/wiki/Aluhotend
My money is on QU-BD copying his design, not the reverse.
@Normand_Chamberland , QU-BD has been producing these nozzles since the MK7 or so. It’s a pretty common MakerBot nozzle. The history on the AluHotEnd only goes back to late 2013. So I think you are likely wrong in this case. The second, less sharp nozzle in the picture is a MG nozzle.
The wiki page history only goes back to late 2013… But you’ve been around the RepRap movement much longer than I (and I only in a lurker capacity) so I’ll defer to your arguments. I’ll admit I may be biased against QU-BD considering their bad rep.
Oh believe me. Fuck QU-BD. I’m doing what I can do move us away from their trash. Why in fuck we’re using MakerBot clone extruders is BEYOND ME.
Man that’s an ugly hotend… 
I’ve got one of these on order… That I can change over from direct-drive to bowden without replacing my hot-end and the price was the two selling points. The JHead is going into the ‘backups’ box.
