There is a new class of SLA (Stereo Lithography) 3D printers that is using an LED screen to generate the UV light, instead of a laser or DLP projector. This innovation is bringing the cost of SLA way down, as low as $250!
The SparkmakerFHD is selling on Kickstarter for only $250. It is big enough for making miniatures and jewelry
Another is the Anycubic Photon for a little more than $500, and is great for miniatures.
I have been watching the adoption of 3D printing by the Tabletop Wargaming community, and I think this class of printer is making it possible for gamers to print their own 3D printed miniatures at home.
I believe this technology is a game changer for the hobby of tabletop Wargames and miniatures, because the detail is much finer than can be created through traditional molding, and the cost of printing these miniatures is much less that the mass-produced ones.
I wrote an earlier article about this 3D printed alternative to traditional miniatures
