Skull with Brain

thingiverse

This is a model that combines a skull with a brain inside. The design allows for empty space around the brain to be filled with liquid as it prints. Check out this video I made using Coca-Cola: https://youtu.be/4hr75JSFLsM I used this skull model from BlendSwap: https://www.blendswap.com/blend/10291, and this brain model: https://www.blendswap.com/blend/13180. To fill the liquid into the print as it's going on, I employed a syringe to slowly inject Coca-Cola at intervals without pause. Since the brain is a solid object, the printer spends more time working on it when I injected the liquid. However, this method isn't safe and shouldn't be attempted. Here's what you should do instead: modify your gcode file so that it pauses around 80% of the print. Then, inject the liquid and continue printing. Viewing the layer by layer in your slicer will help you determine when and where to insert the liquid for optimal results.
