I badly want to do this (I have multiple MRIs of my brain because I have MS). Thanks for the information on how you did it. Would you mind if I picked your brain when I try it?

Katlee- certainly! It's been a while since I did it, but I'd be happy to help any way I can!

Lowlight - I didn't try Slicer. I use Paraview professionally, so I'm quite comfortable with it, and I found it can export to .stl files.

I was looking to do the same thing with one of my own MRI scans and was looking at using Slicer (http://www.slicer.orgwww.slicer.org) to process the DICOM. I'll have to look at Paraview. Did you try Slicer by any chance?

Thank you very much for sharing your brain with us!

BTW. Your Cerebellum looks a tad rough. Tsk! A case of less Tequila and more crosswords, I think. :-P

The cerebellum's the lizard's brain! Crosswords won't help that! Although you're right that Tequila ain't exactly cerebellum-juice.
However, blame it on the MRI. It's more tuned for cerebral tissue. Even then, there are some actual visualization issues:
-Alpha: Because the top of my brain actually fell slightly outside the scanning volume, there are some jagged edges there.
-Beta: It's only a 256^3 volume, so the scanning noise can really distort the isosurface. Which is why my cerebellum looks like someone took to it with pinking shears.

P.S. I'm actually quite good at crosswords!

Hi there, brainy!

Your use of the word "rubbish" marks you out as either a Brit or Antipodean. I'm in UK. I'm not exactly a highly experienced user as I've only had my 3DP a week or so but I'd be happy to help you if you need it. I can certainly print small versions of your brain. Cheers!

Nope, I'm a Yank. Just grew up reading too much Dorothy L. Sayers, I think.
As far as printing goes, I'm most curious as to how we can squeeze the finest 3D resolution from our Ultimaker, just to know how intricately I can design my models. Anything you learn which can help craft really intricate designs (optimal PLA temp, speed, layer width, etc.) would be much appreciated.

"Cheers", and "Have A Nice Day"

Well, Matt. What I've learned so far is that PLA is a bit of a pain and that the only supplier I'd use is Faberdashery. High quality, great range of colours etc. My Up! Mini runs PLA (1.75mm) at around 220 degrees. A heated bed at 50-55 degrees helps. Kapton works with PLA. In fact results are really good. Oh! and PLA could in no way be described as dishwasher safe! :-)

And as for your isosurface.....Think that's best kept to yourself!

Cheers!
