On the theory that everyone needs a complete T-Rex skeleton I've spend the last few years conducting a yearly dinosaur fossil hunting trip in Montana & South Dakota as part of a team from a local Zoo where I was on teh volunteer staff as an animal handler & kayak guide. Although I've amassed a fairly decent collection of dinosaur bones as can be seen in the attached pic, including a large piece of Triceratops frill, a raptor tooth and even some amber, I've never been able to find and verified pieces of a T-Rex, let alone a complete skeleton ... lol. therefore I decided another solution was in order where I could make use of my PRUSA XL.
Although I'm currently working on a full Halo Master Chief cosplay outfit my printer is idle while I work out the mechanics of casting the individual armor pieces in a flexible resin and so I decided to put it to good use.
First up was to acquire an appropriate 3D model. After a few weeks of research I found a beautifully detailed, highly accurate model. The only issue was that it was only about 15" when fully assembled which was just a tad small for what I was going for. Not to be deterred I loaded each of the 42 individual pieces into my PRUSA slicer and started scaling them to see how big I could go without having to slice any of teh individual model pieces.
Long story short it turns out that a scaling of 495% allows me to print teh complete skull in one piece and only a couple of the vertebrae needed small sections sliced to fit.
First up I decided to print the lower jaw ... here's it finished, primed & sanded and ready for attachment to teh skull & painting
Next up were the tail sections which were 4 individual pieces that needed to be eventually glued together. Here's the fully assembled tail and a closeup showing its overall length of ~ 58"
Next up we'll start working on the vertebrae and rib cage
