Help, parts not showing up in final print!

    Okay, so I've been printing this model destroyer, and when I'm printing the third part of the deck, only the superstructure get modeled in the final print.

There's a few possibilities.  But first ALWAYS view your part in layer view (as shown in screen shot) before printing it so you don't waste time as about half the time I slice I catch something (like this) in slice view.

 

The first obvious possibity is that the part is less than 0.3mm thick.  I know you have Cura set to layer height 0.1 but the first layer (initial layer) defaults to 0.3mm.  So try setting that to 0.1 and see what happens in slice view.  Or thinner.  how thin is that part?

 

Another possibility is that the part is not one solid object (part isn't manifold) and that the part that isn't printing either has holes in its walls or is missing a bottom or has extra internal walls.  View your part in xray view to see if this is true.  Any red areas in xray view means the part is not a solid.  It's not manifold.  You can fix it with the netfabb free repair service here: https://service.netfabb.com/login.php

 

Another possibility is you set Z to a negative value.  Click on the part in normal view and some icons appear at the bottom.  Click on the move icon and it should show the Z position to be zero.  If not set it to zero.

Thank you, I will try that!
