PAHT-CF printing functional parts on Bambu Labs H2D.

Printing in CF-Nylons is like printing with black aluminium. It's as strong by weight, and actually more abrasion resistant, making it the perfect material for a high performance brushless 12v water pump. When printing functional parts with thick walls, nylon is more prone to warping than other materials. In the case of this two part pump housing that is split down the center to allow for some advanced thread placements specific to this design, I needed the mating surface to be as flat as possible for a strong epoxy glue joint. The very tips of the pump exit diffuser would remain stuck to the build plate while printing, but after cooling and removing the part there was some residual stress built up that would curl them up by about 1 mm. I solved this problem by adding a draft skit I modeled in Fusion 360 that could take advantage of the ASA support material I was already using with the dual nozzle to help the 110C bed temperature keep the part warm.

For solid print and thick walls, what are some strategies you have used that can help with this situation or residual stresses in the print?
