Toothless needs support help!

Recommended Posts

Yes, Toothless from "How to Train Your Dragon" is a favorite of mine.

 

And there's a great model (without supports one) on Thingiverse.  (https://www.thingiverse.com/thing:2335797)

 

However no matter what I've done, the supports fail on the wings on the back

 

Using the latest Cura.... and really stumped as to how to get this little fella printed successfully!  It's eluded me a few times!

Ok, I've been looking at those settings.

 

I think the problem is the foundation.  Even if I set a brim, the supports would be weak.

 

It looks like the wings have good support but the base would again be the weak spot.  Can you offer some tips on the Join Distance and Horizontal expansion that might be good to try?

@kmanstudios - but an "infill mesh" does not influence the stability of support structures, right?

So there's no way for a set some solid layers first to strengthen the support to the bed?

 

It depends on the support pattern. I think, "Zig Zag" has always this grid like bottom layer.

 

In general - "zig zag" supports are much more stable if you choose at least one surrounding wall. The setting is called "Support Wall line count". And you should select "Enable support roof".

I decided to go with brim and the changes I posted above.

 

79% into the print and the area that failed previously is working very well.

 

I'll let you know how the finished print does but so far (20 hour print), the big problem area seems to be working well.  I think the brim gives a stronger base for the support and added the one wall helped too.
