Printed in PLA (red-orange, white, gray, black and clear) on a Flashforge Creator. Standard settings as recommended by the original author. No painting of the model was required. (That's the PS3's 'Globe' music visualization running in the background.) It's a great model; I highly recommend it if you are looking for a "showpiece" to print big.
I've also printed it at 30% size (resulting in a 5-inch model, shown in the last picture) with great success. In both cases, I found that printing the black "strut pods" 15% larger than the other parts helps them fit.
