Calling this 3d printed reminds me of how some video games are referred to as 2.5D. It looks like a 2D array of dots without any real third dimension construction other than the volume of the dots. The resolution is also a fair bit lower than even consumer grade 3D printer technology. The current results are already impressive, but it seems they have a lot of headroom to grow into as well. Also, I wonder if the coloring of the dots is simply to keep track of which type each is.
