In the Make Magazine November 2012 issue, they ran a 3D print competition with many of the existing available 3D printers. They ran a test print that had some unique features. It had an unsupported arch, round and hex holes, posts and a box with walls of different thickness. Then each printer created it at default settings.

I decided to try the same print on my Davinci 3D printer and the results were great. I printed with and without supports so the arch failed in the non-support but everything else was fine. It's still not clear to me if support would have been permitted or not. I produced a YouTube video showing the steps and the results.
The .STL file is available on Thingiverse for anybody to try. I printed it at different levels or 0.2 layer and 0.4 layer. The default on my XYZware is 0.4 layer, 10% fill and standard shell and standard speed. The support was low fill. Both the 0.2 and 0.4 looked great.
It's true that the Davinci had two years of development over the printers in the magazine, since it wasn't released until two years later, but a sub $500 printer wasn't available back then either. So I'm once again sold on the quality of this Davinci printer.
