Hello Peter,

thank you for your question and please excuse the delay.

In fact, a higher layer thickness leads to higher strength, but of course then brings the disadvantage of a worse surface.

Infill also plays a role here and should not be too sparse for higher strength (50%+).

In your case, I would choose a layer thickness of 0.2mm.

Experiments have shown that the actual difference is also relatively minor.

Hello! I am currently designing a high-load component for industrial plants using a high-strength polymer such as Ultem 1010 or PC (FDM printing). The component must withstand significant stress and impact.

I’m wavering between a layer thickness of 0.1 mm and 0.2 mm. I know that a smaller layer thickness can affect the mechanical properties, but I’m worried that at a layer thickness of 0.3 mm, small particles/industrial dust might get between the layers, which could affect the long-term durability.

Does anyone have experience with how different layer thicknesses affect the compressive strength, tensile strength, and impact toughness? Which layer thickness would you recommend?

Thank you!

Peter
