Hi everyone! I'm wondering if anyone out knows what the ultimate resolution of cast acrylic is. By this, I mean what is the maximum density (dpi) that can be engraved on acrylic before the "dots" begin to blend together and overlap...

That depends on the lasers lens and spot size.
Generally 0.003" is around the smallest spot size you will get with anything other than specialised optics, so 300 dpi is about the maximum you will get, however there will be a significant heat affected zone around each dot , so practically , its around 150-200dpi.
