This isn't a renderer default pic but a screen shot from the 3D view / java applet....
That java applet should have been replaced long ago with perhaps flash or at least display proper 3D view of our models...
It is after all THE main method for customers and surfers to evaluate the model ... rendered pic even the best ones cant be compared to a nice 3D view (real time and with color).
I hadn't noticed that yet, and my local rendering test works fine. So yeah, it'll print as intended.
A better 3D view is under investigation. Main problem is that the rendertimes are about 100x longer than for a single shot. Stay tuned
@Bart, few days ago i stumbled upon a German website which sells USB and Keychains shells using a 3d color printer - (unfortunately i didn't bookmark the URL) - every model has a VERY cool flash 3D viewer - it loads very fast and display very quickly the 3D model + zoom in/ out , pan , roll etc.. AND in color
This is a must have on shapeways.com
Having said that i have no clue how secure is Flash .. as now days every thing can be de-compiled and source may reveal the STL file of the model for anyone to copy.. :/
