J-head on an Ultimaker?

Recommended Posts

Aren't these designed to have the extruder mounted directly on top of them?

Afaik there is no interface on the J-head to mount a Bowden tube, so you need to have a somewhat more complicated printhead design than for example with the E3D Bowden hotend. I had a look at the J-head (and clones), but that's why I chose the E3D in the end...

I dont know...

The one i got has a screw (called umbraco in DK, dont know if thats an international title...) in the top that can be taken out so the top has internal threads...

A few pictures:

 

 

So im guessing if one could find a coupling that fits the diameter and threads it could be used straight out as a very compact little bowden hotend..?

Would the diameter allow you to cut the threads directly into the bowden with a die, and forgo a coupling entirely?

Sadly not, already tried... I think the thread is M8, the bowden tubes i have both measure just around 6 mm. on the outside, so they are actually quite loose in the hole...

Also i kind of like the push fittings, and how you can easily remove your bowden from them... That gets alot harder if the bowden is screwed directly into the hotend...

    • Architect Design Contest | People
      The goal of this contest is to design a set of people figurines that could be used in such a project to make an area, office or mall seem populated. 
      Think of different types of people in different environments, like walking people, people standing still, working people, and both men and women.

    • Taking Advantage of DfAM
      This is a statement that’s often made about AM/3DP. I'll focus on the way DfAM can take advantage of some of the unique capabilities that AM and 3DP have to offer. I personally think that the use of AM/3DP for light-weighting is one of it’s most exciting possibilities and one that could play a key part in the sustainability of design and manufacturing in the future.
