I have bought several items from Shapeways. Yes, small items like Lego pieces will have some level of rough texture as seen in the Master Sword picture (still looks great to me!). They are constantly improving, plus, if you are crafty, there's easy fixes for the rough spots, applying a primer, light sanding, molding and casting all reduce the overall roughness. I make head models for action figures and I get them printed in "White Detail" material, it's kinda waxy to touch, and has the texture of the Lego slope piece, maybe a little less rough. They look and feel great. If you have more questions, feel free to ask!
