Not printing holes

Recommended Posts

Hi

Please take a look at this image of my object...

http://www.bredel.dk/um2/sokkeltandhjul.jpg

When I open my model in Cura, alle view modes show the center hole.

Except the layer view, where the center holes is filled out...

...unfortunately this is also how it is printed.

So can someone please explain what is going wrong with the slizer, or which considerations I should take to have these holes printed?

Have experienced it with many of my models that have holes?!

Thanks

Kind regards Taras

Might be that the normals of the holes are the wrong way around. Then Cura can decided to fill instead of keep a hole open.

In the expert settings there are "fix horrible" settings, unchecking the "type A" one changes this behaviour.

"the normals" is a unfamiliar term for me.

 

In sketchup the default surface is white on the outside, gray on the inside. You can right click on any triangle and swap sides. This could take many days if you have hundreds of thousands of triangles that need swapping. Fortunately Cura has a "fix horrible" option to take care of this.

While I love sketchup, it's not very good for models to be printed.
