An anatomical model of a human heart, painstakingly assembled from obj files taken from BodyParts3D's database. They claim that I have to say this: "BodyParts3D, © The Database Center for Life Science licensed under CC Attribution-Share Alike 2.1 Japan"


There are a couple errors in the STL mesh that I couldn't seem to get rid of, but it printed just fine. It seems a little larger than life-size, but I'm not really sure; I've never seen a real human heart. With 1:1 scaling this is nearly as big as a Makerbot Replicator would be able to print.

I used ReplicatorG (skeinforge) with raft and support turned on. "Support Minimum Angle" was set to 85 degrees, so it didn't build very much support at all. I also set the "Support Gap Over Perimeter Extrusion Width" to .015 so the support would detach more easily.

Do you mind if I make a wax mold out of it? I will pass it through maya for a higher resolution and obtain the two parts for the mold..

Yes of course, it was obvious, I just wanted to be polite asking you first :)

Thanks! I can't wait to see what you make.

I will probably be reprinting,

"An adult heart has a mass of 250–350 grams (9–12 oz). The heart is typically the size of a fist: 12 cm (5 in) in length, 8 cm (3.5 in) wide, and 6 cm (2.5 in) in thickness. Well-trained athletes can have much larger hearts due to the effects of exercise on the heart muscle, similar to the response of skeletal muscle."

Let us know what scaling factor you decide on to be most realistic.

I printed one and it turned out really good. Thanks Drew!

This is super awesome. Thanks for the great model. Any chance you can post a model that doesn't have the bottom sliced off? Thanks again!

Nope, this is the only file I have.

I was diagnosed with a dilated aortic root (aneurism) and this is the highest quality 3d model I've found. I printed and used to explain to my family/young daughter and friends what I am actually having replaced (I just got a dacron aorta). Many thanks to Drew for all his hard work in making this available. It was much appreciated resource in explaining to people my condition and your work is hugely appreciated.

If anybody happens to build the cross-section version of this, I would LOVE to get a copy. I actually got my 3D printer yesterday and the first "Could you do this?" question was a biology teacher wanting a 3D human heart that she could show students.

I am looking for the same thing, have you had any joy finding a cross-section version? I need one for a university project I am working on at the moment.

I have had no luck. I have found anatomically accurate hearts -- but nothing with the internal structure. I may build one this Summer, but I was hoping to get some models to my anatomy teaches before I leave in June.

Very nice! Is the inside solid or can you cut it in half to show the chambers?

To get it to print well and quickly as an exterior model, I've stripped out all the internal features. It took a lot of work to do, but I think it's worth it for my intended purposes. If you'd like to create one that is cut in half, the raw STL files are available for download here http://dbarchive.biosciencedbc.jp/en/bodyparts3d/download.htmlhttp://dbarchive.biosciencedbc... .

Unfortunately, due to how their database is organized, you'll have to download a multi-hundred mb zip file and piece together about 9 of the included STL models, each of which is named with a seemingly random code like FMA3669 (i'm not sure if that's really one of the files, I don't have the list with me right now). To find out which codes you need, you have to use their strange web-viewer interface, which is quite difficult to navigate. (They also provide a .txt file which I did not find to be useful.) Then, after piecing them together, you'll probably want to trim the arteries and veins back down to a manageable, printable size.

To be fair, though, their database is worth every penny that it costs!</you>

Thank you very much. What a great tip and resource!
