The 3D Printing world is expanding. It is relatively amazing how much has already begun, and we're probably likely to see way more moving forward. For those who don't want to mess with a 3D printer, there are folks starting to pop up who are printing on demand.
One guy I know is printing on demand for folks locally and through the mail. He is doing figures from outfits like Medway Miniatures, Reconquer (formerly Caballero), and Felipe Manivel. And he is providing these primarily in 28mm or 40mm, but capable of adjusting the size down to 15mm, 20mm, 25mm or up to 28 heroic, 30mm, 54mm, 60mm, whatever a customer prefers. Turn around time is typically no later than 3 days printing plus mailing time, and he's had to expand from one printer to using three, including one of them for larger prints.
This is going to only get bigger and more variety is certainly going to happen.
I've already purchased 12 English archers (almost completed painting and basing), and have 36 Spanish Levy (archers, javelin throwers, and spear men) ready to prime.
