FDM for Vacuum Forming

I am somewhat confused by the comments from several list members who have
stated that FDM ABS parts are great for vacuum forming because of the
inherent porosity. I assume the porosity comes about because of gaps in the
layer to layer adhesion.

If the parts are inherently porous, how can it be that FDM ABS parts have
nearly the same mechanical properties as injection molded ABS?
