Indeed we noticed this too..

We have another theory that could explain this also, Stray laser light.
We have an alarming amount of light scattering far away from the focal point of the laser.
in arias that are more complex ( like the ones you point out ) the aria around that complication may get enough stray light to cause the surface of the resin to partially cure, to become so viscose that it has trouble flowing in over the printed wall.

Been working on better laser focus along side about 5 other theories , hopefully will have it solved soon.
The laser focus problem has been fun, iv been staring at beautiful diffraction patters for days, and learned about electro polishing, and how to machine very very small holes.
Light has some mind boggling property's.
as for focusing the light, I was wondering what about having the focal lens after the aperature, in the assembly videos they show mounting a small aluminium disk with a small hole punched in it stuck on top of the laser module after the focusing lens, if you reversed it you would be focusing the small beam instead of restricting an already focused beam, this might solve the stray light problem as well as possibly producing an even finer beam allowing for even better than your already awesome resolution.
