Its really cool seeing what everyone has made with 3D printing. The terrain especially really looks cool.
I think one aspect why I can see 3D printing taking a larger role is the loss of the FLGS to play at, if it was ever there at all, in some parts of the world. The reason I sometimes consider it is because I have to bike 40 minutes to go to the city to visit a shop, there are four of them within 5 minutes walking distance from each other.
One switched to board games only years ago (no room to play, just sells),
Another switched to escape rooms instead of wargames (still sell board games and magic) and they never had room to play even when they did have various wargames
The third has room to play but has stopped doing kings of war to have more room for magic and occasionally rpgs.
The fourth is games workshop. It is the only one that runs demos and has tables to play at, but only for warhammer of course.
So I can’t just pick up a box of dudes, even though its only a few minutes out of the way of my commute (I wanted to pick up the book for KoW with cash real quick for example and went home empty handed. Ended up not getting a physical version of the book at all). I have to order things if I want them, and none of the shops in my country have the combination of good selection and a usable webshop. So I end up ordering from Germany or the UK anyway, and need to order in larger batches to mitigate the shipping costs.
I can imagine that there are other places, particularly remoter locations, that face similar problems that at home 3D printing might help after the expensive initial buy in.
