Hi @SandervG, thank you for the feedback!
I am aware that these parameters all influence accuracy, however the material shrinkage would be something that, given a reasonably controlled manufacturing process and proper filament storage/handling, should remain essentially constant, which means that it could be most probably compensated for in a material profile.
As the new materials you are introducing are most useful for engineering applications (not much sense in printing a figurine with a fiberglass filled filament), I think it would be good to really put a focus on print accuracy.
One idea would be to provide two profile sets - a "fast/draft" option with fast printing speed, and a "engineering" option that provides maximum dimensional accuracy (not only outer dimensions, but also inner holes etc.)

Hi @P3D,
thank you for your questions! I was out at the TCT show myself, hence my late response.
Yes that is what I mean. The Ultimaker 3's feeder is not equipped to handle abrasive materials, the teeth will (quickly) wear off. How fast, depends on the material you decide to use. The Ultimaker S5 feeder (in particular the knurled sleeve) on the other hand is made of a hardened material and is also coated to make it even stronger.
The dimensional accuracy is a synergy of the print profile used (like speed and temperature), the material (like shrinkage) and the printer itself (calibration). So it is hard to say by leaving two of the 3 influencers out of the equation how accurate it will be. I believe the added glass fibers make it less prone to shrinkage, which should make it more dimensionally accurate. I'll see if I can report back with something to make it more tangible.
Let me know if you have any other questions ?
