I recently read/watched/listened to a few social media commentator types (a lot like me) who all seemed to be of one mind that 3D printing wasn't a problem for GW. I very much disagree. Sort of.   In the first of a two-parter, I take a look at how 3D printing may affect GW's business model and why, look at why people think it "isn't a problem" and why they're wrong, and what GW could and should do to adapt their business model to 3D printing.   In the second part, I'll look at the wider world of miniatures wargaming, where the impact is, I suspect, going to felt much more keenly.
