WSF Separation Distance

I'm working in WSF and having some issues understanding when a hole will be preserved.

I have the following design:



My hope was most of the holes would be preserved. It seems like most where not. Is there a guideline for how small a hole can be. I can't find one on the material page. I feel like it used to be there.

it feels like the powder could not be removed from the holes. I made this 1mm thick so perhaps it would have broken if the depowder air was really forced onto it.

If I make this part thicker do you think it can be better cleaned(if that is the problem)? Or do I really just need to make the holes larger?

Originally the holes where larger but then the wallthickness was below 0.7mm. I tried to respect that more by thickening the lines but I'm not really happy with the final outcome. A lot of the holes are 0.5mm square or greater, they have an indent but don't go all the way through.

I'll put a picture of the 3d printed object next message.

Here is the printed object.

this was the document I remembered, thanks. Add my name to the list of people who want to specify orientation of my printed part and I'm willing to pay more for the consistency. There are some designs which could be 3d printed nicely but they would have to be printed in the same direction each time.
