E3D Titan - A powerful, compact, lightweight extruder. Technical review and video.
http://e3d-online.com/blog/titan
This is what we’ve been working on for the past few months besides BigBox! Learned so much about injection moulding, the intricacies of filament drive teeth and stepper motors.
Clare has done a crazy-awesome job putting together the flashy video, a bit of a departure from our normal style, but I hope it’s informative!
I know I’ve been pretty absent around these parts lately, but I will be here answering any questions you guys might have. @Joshua_Rowley is also online and was the engineering lead for this design so is well placed to answer any questions!
The documentation is up and I would welcome any feedback:

nnnngh… You guys at e3d just seem to nail it every time. I think this will be the next addition to the FB2020. At £63 with bowden adaptor and mount + shipping, it’s pretty damn competitive too!
@Mark_Ellison The motors we supply for use with Titan do have a D-flat, but it’s not really necessary and the set-screw on the smaller metal gear will easily clamp effectively onto a round shaft.
@Sanjay_Mortimer1 Definitely upped the ante with presentation this time!
@Sanjay_Mortimer1 - quick question, if I may, the tooth profile of the extruder gear, I’m taking this was a follow on from the HobbGoblin?
@Robert_Cicetti I know right, @Clare_Difazio worked with an amazing 3D animator to create it. It’s a bit of a departure from our old style which I don’t want to abandon, but the 3D renderings are so informative and show things that you really wouldn’t be able to see with footage of black plastic parts inside other black parts!
@Ax_Smith-Laffin Yes, absolutely. We took the basic concept of HobbGoblin and did a lot of testing and refinement. Settled on a new smaller tooth cut with a new tool which results in much better and more consistent grip. The new profile was tweaked to death to squeeze out every last drop of grip. I didn’t expect it, but making very small and subtle changes around things like the tooth count and spacing resulted in us gaining around 40% more grip. Surprised me.
We’ve now actually pushed this new tooth-profile that was developed for Titan back upstream to the HobbGoblin products, which from now on will have the new improved tooth profile.
Thanks @Sanjay_Mortimer1 , that’'s good to know, I may dive in and grab a new HobbGoblin before I take the full plunge on the Titan. The HobbGoblin is an evil little drive gear, I’ve had no slipping at all with it on the Schlotzz extruder, with the improved tooth profile, it can only get better.
Oh god yes. Just what little printing I’ve done on my Maker Select has convinced me the biggest problem is the extruder
Seems to waste a lot of vertical print height though…
Already on its way from Filastruder. Can’t wait to try out this bad boy.
Can it handle flexible material on a Bowden (Rostock)???
@Sanjay_Mortimer1 It seems you use motor shaft as hinge of spring arm, any chance of wearing out after some use?
@Sanjay_Mortimer1 One more question, how acetal gear attached to metal drive gear? I’m looking for solution for my DIY geared extruder.
