During printing, the filament can change its aspect from a shiny surface to a matte surface depending on multiple factors like temperature, speed, layer height, minimal layer time and cooling.
Most of the time, some sections turn from matte to glossy because the print speed slows down and the filament spends more time in the hotend.
This effect is easily seen on more shiny filaments like Silk PLA filament, or PETG basic filament.
1. The printing speed of different model sections is significantly different
In the example below, you can easily see the purple section in the slicer having a much slower speed compared to the rest of the model.
To solve this problem, and avoid this issue in the future:
The speed reduction can be made from the Outer Wall setting, under the Speed tab
A community blog post explains this issue in more detail, and it is available here: Bambu Studio Fine Tuning: Tips and Tricks
2. Inconsistent finish when fast printing at very low layer height
When printing models with a very low layer height (such as 0.08 mm) at high speed, you might see that the model generates a fish scale effect as the one shown in the images below.
This occurs due to a combination between low layer height and the forces applied on the filament when printing very fast that shear the filament.
