The New 3D Printing Thread

The tracks look a bit rough for the monorail. Do you know if it will be smooth enough for the monorail?
I have noticed when playing with the monorail that some tracks that are not smooth can easily stop them because the monorail 'slides' on the rims of the track.

No, we don't know, yet.

These samples have been printed in quick 'draft' mode, i.e. a relatively wide nozzle and a relatively thick layer size, purely as a test to see if they are OK dimensionally and that the elements are in the right places. That said, I'm hoping that they will clean up sufficiently to be usable.  I certainly agree that the Plarail monorail trains can be a bit temperamental, but the design of this slope rail has more roughness on the faces that the tyres run on than the original injection-moulded MR-02 did, which in theory ought to help.
