#Do we know which has the stronger layer adhesion?

I need the stronger layer adhesion to try making an air hammer head.
Not sure it will survive the impacts, but I will use plain Pla Ingeo 870, like for my press tools that are regularly under 5 tones.
Perhaps I'll do annealing step this time.
So, is it better to have small line height and width or bigger ones to have more impact resistance and layer adhesion?

For improving layer adhesion and impact resistance, it is recommended to have smaller layer heights and widths. This allows for more contact points between layers, increasing the overall strength of the part. Annealing can also help to further improve the physical properties of the PLA material. It's essential to experiment with settings and conduct test prints to find the optimal balance between resolution and strength for your specific application.

Larger layer lines can help with strength

#

Use a 3D infill to help as well

I imagine smaller lines = better layer adhesion but weaker line and the opposite for bigger lines, but not sure.

Does someone else have info on that question?
I'm watching My Tech Fun to see if he has something but not that much on layer height or nozzle diameter

also as a general rule, more walls = more strength

#

but ig if youre running 100% infill its all gonna be "walls"
