Hollow print is solid

i tried to print this:

However I stopped the print when it had got to be 12mm high because I was convinced that it was just going to print a solid block instead of a cup. The downloaded picture in cura does look to be solid yet the item description is that it is hollow. any ideas?

Instructions

The trick:

- use a 0.8 mm nozzle [instead of standard 0.4mm]

- print with layerheight 0.4

- with skeinforge 39 [or higher] use fill, with solidity 0

- to get a nice bottom set the 'extra shells on alternating solid layers' and the 'extra shells on base layers' on 999

- for raftless printing: turn ON raft and set the base and interface layers on 0

set the first layer feed and flow rates at 0.25

- to not close the vase: remove the to 2 layers in the gcode file

- heat up and go!

and I think in Cura there was a special Vase setting, you might try that also.

Thanks for that , I'm using Cura so I've not got those settings available so all I can use is the vase setting. will that on its own give me a hollow print or do i need to do something else?

I think just doing it as a vase setting should give a hollow print.

(Disclaimer, I have never used that setting myself)

maybe do a small test print, instead to wait for the end to go wrong.

I would notice after a few layers as my first attempt was filling in the base , if I dont see the sides appearing after about 5mm then I would assume that it was printing a solid again.

Tried it with the vase setting and it worked. I just don't understand why it was printing solid in the other settings? surely the fact it is solid or hollow is set within the code for the shape and is not up for interpretation by the machine??

The vase models are tricked, they ARE solid models as the 3D preview shows, and then you just don't print the top and insides. This makes it very easy to model them, quick to print, and easy to change. The whole vase/cup printing setting is tricking the software in doing the "wrong" thing so you get the right result.
