Leaky joris vase

[morsch 0]

Hi folks,

I'm trying to print out a vase to give away as a present. Unfortunately, it leaks! The bottom looks more like a fine sieve than a solid part. The sides, on the other hand, look perfect. I've tried a few different settings, but I couldn't really see any difference to the bottom. Spiralize contour is always set, of course.

This is the one I've been trying to print: http://www.thingiverse.com/thing:52200

Here's a pic. It's not brilliant, but if you look closely, you can see the red of the mouse pad shine through. When viewed directly, it's even more clear; there are gaps everywhere; half a mm in width I'd say.

I've printed vases before and they always turned out fine. I'm not sure what's happened. It looks like Cura'd need to add twice as many lines on the bottom layers. But maybe the grid was always that coarse and I've got a flow problem?

Thanks in advance.

Moritz

What hardware are you printing on, and at what temp, shell thickness, and layer height?

Ultimaker 1, print speed 50 (default), shell thickness 0.8 (default afaik), I had tried various layer heights between 0.1 and 0.2 -- didn't make a difference to the problem.

The temp, though, did, I had always used 220, and repeating the print at 230 did the trick! I guess using a non-heated bed made at least the first lines put down stop flowing before a solid layer could form.

230C and 110%-120% extrusion usually does the trick to get a large amount of the Joris prints water tight.
