Hollow Object inner support structure

[haftting 0]

As quotedd I want to print a hollow objecct (see pictures). I was already able to print that one without support structure but the result wasn't really satisfying at some points, therefore I thought modeling a supportive structure inside the object could help. Unfortunately, when slicing the model the modeled structure is totally gone and I'm asking myself why this is happening. 

I'm quite new into 3D printing and thankful for any advise.

Thanks in advance

I’m going take a guess that the walls you have in the model are to thin for you to print. If using a 0.4mm nozzle your wall thickness needs to really be 0.4mm but you can get away with a little thinner.

 

So you could try editing the model to add some wall thickness or you could try smaller nozzle sizes.

 

but basically if your settings have a line width of say 0.35mm any walls thinner than that it not be able to print.
