help with printing issue

Recommended Posts

Hi, I have issues with printing the ribs, it prints fine for the two thirds of the print ribs1.JPG.

My guess because the object is moving at that moment and is unstable.

So second try I add support but you see, it's still bad :-( ribs2.JPG

can you please help me out here? I used for both prints a raft.

These parts are wobbling while printing. There is no simple solution but there are several solutions.

1) You could put better support on these such that they don't wobble so much. The built in support of cura 14.X and 15.X could be better. Try cura 2.X (the latest) support features - they really improved the options on those and you can have the supports follow further up the ribs.

2) You could lay the ribs flat. They will then print much better. But you will get a larger area where support touches the rib that will look - less pretty - but at least the prints won't fail. This is probably what I would do.

3) Design your own supports. If you don't know how to use CAD software this might be an opportunity to learn one of them.
