If you really want conformal layers you need a five axis platform. The flat tip of FDM nozzles is an important part of layer adhesion. I've seen a little bit of experimentation with pointier nozzles and it went very poorly.
Nowadays I'm building the five axis version and packaging it up in a service , along with a bunch of other improvements that are only feasible when you stop trying to build a machine lay-people can operate.
Can't wait to see more of what you are doing soon.
I should have some fancy demo prints online in a few weeks here, keep an eye on the website!
