I recently worked on a model of a 3D disarticulated skull with Pixologics ZBrush. It was quite a large project to take on in the way of ensuring accuracy and especially the accuracy of the sutures in order for a perfect fit, one piece to the next. This is a temporary turntable that needs updating with the many parts of the ethmoid remaining together as one piece. I will reveal the production process involved in this later in the year. In the mean time if you want to see it in high quality print you should check out Dorling Kindersleys 'The Complete Human Body' which I worked on heavily last year and earlier this year.
