That looks like the back end of the "Orville" which does not have a straight line on it. It seems that you may have your support on the piece a bit strong. What support settings are you using?


Edit: Also, what slicer?

Try this setup:



1. To test your breakaway supports (assuming you are using one extruder), sink below the buildplate to minimize time and materials.

2. I will sometimes cheat a bit on the quality settings for support by lowering the support line width. This can make the supports more flimsy though, so,,,,,up to you.

3. Play with the Support Z distance to find a balance between supporting and just not enough contact.

Cura 2.x has the same properties I am showing. No need to cut the model, just move it below the plate. You will probably have to turn off the "Automatically drop models to buildplate." so it is easy to do so. But, everything else is available that I used or mentioned.

Those are the things I know to do. I actually use PVA for my supports. But perhaps you can look at a thing or two such as maybe less dense supports or even maybe playing a bit with the angle so that you have less support.

You dialed the separation down to less-than-one-layer (It'll round up)?


You could play with the interfaces (support floor/ceiling), that should help.


If you're desperate, perhaps lower temps would help, but you shouldn't have to do that.

    • 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.
