For this particular model, I used support on the build plate only and few small support enforcers for the overhanged parts of the big vessels. I also added a "box" support enforcer from the base to the level of the valves, because with support on the build plate only there is a small part of the aortic valve, which doesn't print well. With those settings, the entire athriums will be clean and the vessels will be steady. It requires to play a bit with the settings, but at the end the control over
Hi @valchanov and thank you! I was actually wondering where exactly you put the blockers... well I'm almost done my first print of this, and I just enabled support everywhere (but from bed only) so we'll see how it looks... I'm using MK3S and PrusaSlicer too.
