3d printed bricks quality? I know Lego has high quality bricks, but would like to know how 3d printed quality compare ? I would also like to see the kinds of tricks you use to enhance your print quality.

For what it's worth, I don't use 3d printed bricks. Just thinking about it, but searching on Google only give me information on how to convert from LDR to STL.
There have been various questions asked here previously regarding 3D printing, with very mixed results.  Here is a link if you are interested in the responses to those questions.

The experience you are looking for to answer your question is slightly out of the scope of what we generally do here on Bricks StackExchange.  I would urge you to check out this more specific 3D Printing StackExchange site as it would seem more fitting and hopefully more helpful then what we may be here.
