Look in the lower right corner - can you setting it to 300 layers or 400?

Welcome to 3dPrinting.SE! What have you tried to change in order to get it to render? Is it throwing any exceptions? What *isn't* it doing exactly?

@Pᴀᴜʟsᴛᴇʀ2 I added what the model looks like and what it looks like when rendered

The second image helps a lot so we can understand *what it should look like*. Is this a print you got from Thingiverse?

(Asked by: username_0 on 2019-04-18)

I am trying to print a belt but when I preview it, the model doesn't fully render

[![Screenshot of half rendered preview](https://i.sstatic.net/s9PtZ.png "Screenshot of half rendered preview")](https://i.sstatic.net/s9PtZ.png "Screenshot of half rendered preview")

It isn't rendering the full model correctly. The model is rendering halfway but isn't fully which is why you can still see the infill when the slider is at max which isn't normal.

This is what it *should* look like:

[![Screenshot of fully rendered preview](https://i.sstatic.net/eG3Lv.png "Screenshot of fully rendered preview")](https://i.sstatic.net/eG3Lv.png "Screenshot of fully rendered preview")

I have a 0.4 nozzle and those with a 0.6 have been able to print this. What is going on?

First I thought that the model was improperly modeled due inverted faces or any missing line to close that faces but, I rendered the same STL to be printed 0.4 nozzle with height 0.2mm and looks pretty well.

However the recommended settings for a 0.4 nozzle should be less than 80% diameter = 0.32mm as maximum to get a proper bonding.

So, I think that you need to download the part and render it again. The time to process this render under XP with an small PC last for 5 minutes. So on bigger PC's will be faster.
