Let's start with the general design look and feel: This printer contains a robotic arm with a toolhead, pretty similar to a welding robot, and probably is controlled with a similar CAM software.

The really interesting part here is the tool head. So let's look at it and try to reverse engineer the use of some parts by how ...

Most CAD tools generate quite low-res triangulations. The ideal solution is to avoid using the CAD tool to generate them. For example, if the print shop can accept your CAD files directly, they may have other software that can triangulate them. For example, if the shop uses GrabCAD Print to slice your parts, that software can open CAD files directly, and ...
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 ...
