Build Your Own SLA/SLS

Hello.
I encounter the following problem in most models I try to print (the more complex ones), no matter what computer I am on.
CW on around 10% of the layers generates horizontal lines that end up being holes or missing parts of the model alltogethere. The meshes are all collapsed, closed and checked but I cannot seem to get rid of this problem.

Most times line appear like this is because the model is non-manifold (not watertight). You may wish to test the model in another program and see if you can repair it. The debug window will also give you some additional information .

Ok, thank you. Ofc I tried my best to keep the models watertight but most programs fail to fix them or just crash. They are complex models with 200.000 to 1 million polygons.

I have the best luck with NetFabb software...
