In regards to a part that I'm having printed remotely (by two processes:- stereolithography and laser sintering), I've been advised by the 3d printing company that 'the triangulation of the file is rather rough'.
In this particular instance, it probably doesn't matter, but for the future, are there any tips to improving 'triangulation' when generating forms in AutoCAD?

The phrase "triangulation of the file is rather rough" is somewhat vague, but one can interpret it to mean that the surface is what is considered "low poly" in the 3D modeling world.
From Thingiverse, this low poly fox shows an intentionally reduced poly surface. I'm not suggesting that your models appear this distorted, but it may give a hint to what the service is referencing.
Consider to load your model into a program such as Meshmixer, which will show you the triangles in 'W'ireframe mode. If there are few triangles over a surface, you can get the aforementioned effect.
Meshmixer also allows you to increase the mesh count, possibly improving the surface and satisfying the requirements of the printing service.

If you don't wish to send your original CAD parts, check if your tool can export Parasolid files (.x_t or .x_b). They contain the original boundary representation your CAD tool uses to represent geometry, but not the feature structure, constraints, or design intent.
