Just published on Toms Guide is a review of the Formlabs Form One+, a high-end 3D printer that uses a resin material.

The benefit of the SLA printing process that the Form 1+ uses is that you can create very thin layers that result in extremely fine detail. The downsides are that it is complex and requires special resins. Oh, and it is expensive: $3299 for the printer and $149 for each liter of resin. This is still an evolving technology, though, and there are a few quirks on this printer.
