Johnno, I think you haven't seen a properly printed, quality, 3D RESIN print. Yes, some are brittle, depending on the mix of resin, but a Filament 3D print cannot match the resolution and surface quality of resin. Resin is durable if mixed properly, but, not as durable as what a filament printer can provide. That's the trade off.

Here's a print of some louvres I had commissioned by a well known modeler in Germany. This is impossible to achieve with a filament printer, period.
           


Here's another print of a rear engine cover to turn a GT2RS into a GT2 Touring, printed by the same guy.
