Can a 3d printer make this part?

[curious aardvark]

basically it's possible, not necessarily to the same level of clarity, but definitely possible.
And it would be just as strong.
I actually find that clear pla is tougher than coloured pla.
I often use it for that little bit of extra strength.
Ralph is right, to get good clarity from fdm you'd need to paint it with a resin that fills in the gaps and shape fdm naturally produces.

Clear pla works well, as does clear pet-g. and hdglass (pet-g).

With a resin printer it's possible to print useable spectacle lenses.

It's swings and roundabouts. resin machines do some things fdm machines can't and vice versa.
