I noticed that when printing small teeth on a pulley that the angle is not matching the design angle. I am printing without any support structure.

Overview:

Detail:

Printed:

The printed overhang incline angle under the tooth looks good (maybe not quite steep enough;) but the top angle of the reclining section looks too flat. It is as if the tooth is too perky.

(I have observed a similar behavior when printing overhanging corners. They build upward more quickly.)

What is causing this, and how to prevent it?

I reduced the speed for the outer layer to 30 mm/s, the infill is set to 40 mm/s. Layer (Z) is set to 0.1 mm. Material PLA 1.75 mm, nozzle 0.4 mm.
