Any way to make the Hot End Isolator be rigid/fixed inside its hole?

Recommended Posts

(On my two UM2 machines)

It seems there's a tiny bit of wiggle room between the printing head's lower aluminum plate and the Hot End Isolator.      It's a very tiny bit of wiggle, but I'm curious  whether making that joint rigid would improve printing accuracy at all.  

Has anyone experimented with this, or does anyone have a trick for eliminating that wiggle?  

Last year I had an Isolator that wouldn't fit all the way down inside its hole (it wouldn't seat against the aluminum plate) because it was too fat near the top of its thin cylinder.  That wasn't good for fitting of the spring replacement, but it sure made the block and nozzle rigid.   I replaced that isolator with one that would seat properly.

I'm just not sure if the feel of rigidity would actually translate to better prints

The Ultimaker Hot End Isolator was had a small fat section at the top which would be tight in the Aluminium Plate and the bottom bit would be loose.

3D solex have a Hot End Isolator V2 which is fat all the way down. this should stop any wiggle.

You could also print a Spring replacement part and that should hold it flat.

If you use the spring on that um2, you could increase the pressure on the steel coupler by leaving 1mm of distance between the ptfe/steel, by rotating the steel coupler counterclockwise. That should generate enough pressure to keep all without wiggle (don't leave more than that or the pressure will short the ptfe life span). Also, there's fixed spring replacements. They recommend to print it on xt/hightemp, but I use one printed on pla that so far it's alive and kicking for almost 3months without signs of deformation.

      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.

      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.
