Disconnected (missing) layers

[RaimoR75 0]

Hello!

 

I have problem with some missing layers. When i Slice my slt and model have level middle of object, slicer drops one or two layers. This happens if model have holes and when model have straight levels. Holes drop layers at bottom tangent. Here is two pics from sliced objects.

 

Problem was "solved" at hole case by setting adaptive layer height on, but even then there was left weak interface at the bottom of hole.

can you share the model to have a look?

did you check the model with the x-ray view?

Hello!

 

Of course! And one thing... Slicing is fine, if i turn oject to another face down. Problem occurs only when this flat part is oriented horizontally.

 

At X-ray view there is no visual problems...

This doesn't look right at all... 😲

A solid (watertight) model is needed for 3D-printing.

This one consists of 370 separate shells that are not connected to each other:

 

 

Similar issues for the other one:

 

 

 

There are online tutorials for many modelling software products that explain how to design proper models for 3D-printing.

Which program did you used to create these?

Hello!

 

Oh my god! I use Freecad and i Exported models by selecting everything with box selection... I followed generall tutorials, but have to miss some step to make model as whole... Thanx I examine this and try figure this out!

WOHOU!!!

 

That cracked the case! I made union form whole object before I exported STL file..

 

Thousands of thax!
