This particular printer is very small, with a print area that's around 10 cm X 6 cm or so. However, since I'm using it for printing miniatures, it's not that big of a deal. SLA printers work by curing liquid resin with either lasers or projector light. In this case, it's a set of UV LEDs whose patterns are controlled by an LCD screen that blocks the UV light. Resin is cured layer by layer, until an object is built.
Building objects took quite a while, and the build area got quite messy due to the liquid resin, which had to be cleaned using rubbing alcohol. However, the results are quite good when the print finishes successfully.
The results look great so far, even without a lot of tweaking from me. I'll be trying more complex stuff with the printer very soon.
