Real human brain from MRI scan

prusaprinters

<p>I recently had an MRI scan (don't worry, I'm fine) and I thought it would make a super cool to 3D print my brain. &nbsp;Now you can too!</p><p>I have uploaded a ‘coarse’ model that doesn't have as much detail but is a much smaller file and is easier to handle if you want to quickly download to interrogate the model or get a quick estimate of print times.</p><p>The model does have some internal structures (although I have removed a significant portion) but PrusaSlicer's “Support All” option can apparently be used to fill any remaining internal voids and dramatically reduce the print time.</p><p>Print settings:</p><ul><li>Build adhesion - raft (maybe not necessary, but there is a lot of separate support material)</li><li>Supports - yes (I used tree supports as I sliced this with Cura)</li><li>0.2mm layers</li><li>0.4mm walls</li><li>3 walls (4 might be better to deal with the steep angles)</li><li>3 top and bottom layers</li><li>Adaptive infill to reduce filament use but fully support the top section</li><li>eSun Marble PLA at 190/65 degC (63 hours (this was before I had done any printer tuning…) and 433g of filament (including raft and supports)</li></ul><p>If you have had an MRI and want to recreate your brain, instructions are available on my website <a href="https://wigglememore3d.com/html/guides/3D_brain_from_mri/index.html">here</a>.&nbsp;</p>
