Here's a pretty cool experiment on how different levels of antialiasing or blurring on a spherical 3D model can affect its 3D-printed surface. (Under the subtitle "Anti-Aliasing in practice with resin 3D-printing")

Is there a set technique or procedure of when we decide to either sample then filter, or filter then sample? I remember that when working with radio signals, we would also filter first before downsampling, but blurred jaggies here is the first time I have heard of first sampling, then filtering.

We can't sample then filter. That's because when we do filter, in this example, we do low pass filter and we will git rid of high-freq signals. After that we do sampling, we will avoid high frequency overlap But if sample then filter, the overlap already appearred, which means we just make the jaggies blurred.
