I'm trying to decide print orientation for a local SLS printer for my parts. I'm considering the three main materials PA, PA-GF, and Alumide. I know that the z-axis strength is weaker than the x-y, so a thin ring would be stronger if printed flat instead of standing on its side.

But by how much?

For appearance, and other factors, I prefer to print my parts with the ring standing on its side to hide the stepping lines on other surfaces of my model, but I'm worried that this would weaken the part too much.

I'm looking at the EOS materials data center:

PA properties appear to be the same in all axis, except the "strain at break" of the Z (10%) is half of the X-Y (20%). Does this mean it is weaker in the Z-axis, or is it just as strong as the X-Y but half as flexible?

PA-GF shows weaker properties in all values in the Z-axis, but still stronger than PA.

Alumide is completely missing the Z-axis data.
