Elephant on Rock

prusaprinters

<p>This is a model of a hollow elephant sculpture. The original elephant could only be made by sand casting, consisting of only a pattern and core box. This was changed using 3D scanning and digital manipulation in Blender, allowing you to print it.</p><p>The model was produced in an unusual way, being derived from scans of the pattern and core box rather than of a positive model. The 'rock' is actually a small piece of the gating system that can't easily be separated from the model.</p><h3>Print Settings</h3><p><strong>Supports:</strong></p><p>Yes</p><p><strong>Notes:&nbsp;</strong></p><p>The supports can be a pain to remove. I used a tree structure to make sure that it was all in one piece, and pulled it out with a pair of pliers.</p><h3>How I Designed This</h3><p>The pattern and core box halves were 3D scanned using the ATOS Triple Scan, a type of structured light 3D scanner. The core box halves were carefully aligned in Blender, and a cuboid was placed between them. The core box halves were subtracted from the cuboid using a Boolean difference operation, producing the core. The core was then aligned to the pattern and subtracted. Finally, the result was subtracted with a plane, revealing the internal cavity.</p><p>&nbsp;</p><figure class="image"><img src="https://media.prusaprinters.org/media/prints/71804/rich_content/00caf610-7026-4ca6-a5c6-2e19c50c8e6b/elephant-steps.jpg#%7B%22uuid%22%3A%22799cb5bd-7ce3-4f6e-a459-e4c89b57ceb7%22%2C%22w%22%3A599%2C%22h%22%3A400%7D"></figure>
