Truly unbelievable!!!!!!!! I even copied the photo and blew it up in Paintshop Pro. Detail is lost but it is possible to see that there is a mass of tiny detail there, around the superstructure. I am guessing that is a sewing pin that the model is sitting on, so around 0.5mm diam. Mind blowing!!!!!
I would love to see a higher resolution image of this, it truly is difficult to comprehend the machine/process that could do this. I believe it was to show what's possible for the medical side. When you consider that today they are 3D printing human organs and have sucessfully printed human tissue with the aim for replacement organs it just shows what the future may be like. As stated this is printed in gold but there was also a mention of diamond..
I'm not sure this is for real, on two counts. Firstly, the Yamato Class Battle ship was 263m long or 263 000 mm which would make a 1:50 000 scale model 5.26mm long. The image with a scale suggests this is only ~0.5mm long. Secondly, it looks like one image shows it sitting in the eye of a needle. Now, we all know how shiny a needle is and this one looks very pitted because of the magnification and yet the scale model is very highly polished. If this is 3D printed, it certainly is not by anything we are ever likely to have access to! A thought however, perhaps it was done on the same sort of machine that the working electric motor, only a few atoms thick, was printed on?

I blew the photo up (no pun intended!). The second photo IS just the ship. No needle eye.
The 3rd photo seems to show that the ship is around the same size, top to bottom, as the needle diam. It looks slightly bigger in the photo but I would put that down to photographic perspective. What diameter of needle? I would guess 0.5mm to 1mm from the surface finish. Call it 1.0mm (typical) and the ship then ends up around 5.00+mm long.
