Yup, I did research on this with my own little slicer [0] back in 2014. With conventional nozzles your surface finish goes to crap past about 20 degrees. 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 [1], along with a bunch of other improvements that are only feasible when you stop trying to build a machine lay-people can operate.
