Second "Included Print File" Printed - Shoe

Here is the completed Macedonia Shoe that was printed in Delaware over the weekend,  The top view does an excellent job of showing how smoothly the Cube prints contours.

From the side, we see how it deals with large areas and holes.

Notice that there was no raft and no support required to print this very complex object.  There was not sign of warping and the only hint of anything but SMOOTH can be seen in one tiny flaw best seen in this view.

This little extra extrusion material was easily flicked off.  In a design this demanding, this kind of performance is astounding to me.

But, there is something else that should be mentioned.  To simply print out the included free creations as novelties would be a big mistake.  They are excellent opportunities for learning.  Freedom of Creation is a company having designers that are masters at designing for 3D printing.  It is highly informative to check on the progress of the print in an object created by them.  It will reveal some helpful hints at how to design so that rafts and support are not needed.

In this shoe, there are some interesting INTERNAL features at the part where the ball of the foot would be and also where the top connects to the back end of the shoe.  It's worth studying these.

Internal Support designed into Shoe #1
The pad in the sole of the shoe (above) seems to be one of the keys to the lack of a need for support.  But, the most interesting thing for me was the upper internal support design.

Cantilevered Support Structure
Kudos to Freedom of Design for coming up with these innovative solutions to reducing the need for external support structures.  And, kudos for the Cube in being able to pull it off.

Click on any of these images to see a 21mpx image that is more than capable of revealing every flaw.  NOTHING stands out as even worthy of notice over 99.9% of the print.
