> CNC machining technologies are becoming much more affordable and easier to use

I disagree with this. The first level of decent CNC machines has been in the $7,000-$10,000 range for quite some time now. As they generally require 3-phase power and flood liquid (generally something which requires a non-trivial MSDS) over the part being cut, they require a dedicated space in a relatively dedicated shop. The "rent" to house the machine exceeds the cost of the machine very quickly.

I would rather have an affordable SLS machine which could print nylon.

Rotary phase convertors or variable frequency drives can efficiently (enough) create 3-phase power from single-phase power, so that's no barrier to even serious home users. I know several people with CNC-converted mills/lathes in their garage/home shop.

I print nylon in my consumer grade FDM printer and the result is outstanding. Something about the way nylon fuses together gives it a really solid feel and nice surface finish.
