Excellent parts, even tougher than I hoped for, these are really going to take a beating! The nylon material has a beautiful surface sheen and there is no cleanup required. There was a little surface warping (bulging) but that's to be expected with 100% infill and I could easily sand them down to tolerance.
Réponse: Agreed re the slight curve to the flat surface. Nylon shrinks a lot as it cools which causes that. And as you've pointed out 100% infill means there's more material to shrink, so the shrinking force is greater. Glad you're happy with them.
