FYI: I printed mine with PLA, temp 200 nozzle, 50 for bed. Support settings are Lines type, 15% density, XY distance of 0.73, build supports everywhere.

Can you please tell me the density of your support, the type of support you used and the support line width used? If you were to use an FDM printer

I have a resin based printer so I couldn't tell you. But there are quite a few FDM makes that specified settings.


I require a model of the heart with the inner surfaces and walls also included, e.g. the walls and passage way between the right atrium and the right ventricle. Does this model also include the inner walls? If no, would you know of such a model?

Kind regards,

@mosiznbd no sorry it's hollow inside without interior walls.

Absolutely awesome model. I made one of these for my wife. She's a cardiothoracic nurse and she's really impressed with it. She wants to take one into her work and use it to help patients understand what's wrong with their heart. Please let me know if you're ok with it being used in this way?

Absolutely that's fine. Glad she can use it to help her patients.

As long as it's not a commercial usage (e.g. selling the model to patients or using the model in promotional materials for that hospital, etc.)

Perfect. Thank you!

Hi Brian, firstly congrats this beauty design.

Which options that we have use for printing this heart. I mean with support or not, vase options or normal printing vs vs. We will use pulse sensor with this heart and will show at the exhibit in our school. I will let you know about the results. :)


Sorry for the late reply. You definitely need supports unless you have an SLA printer.

What do people mean when they say "support"? We just got a 3D printer and want to create this, but I see people saying mesh support, yada yada and all we have is the filament.

Support is what is created on the slicer program. It is the same filament but is printed to help support overhangs and is made to snap off.

might I suggest watching some Youtube Vids on 3d printing. You would get a vast amount of info quickly.

The short version is that most 3d printers cannot print anything that is in an overhang angle. (If it dangles it won't print) So a support needs to be built from the bed up to support this overage.

Hello! I'm a student at the University of Utah and for one of my classes I will be putting on an exhibit at my school about race and genetics. In our exhibit we talk about how race is a social construct. In our display we wanted to show this point artistically by having the same 3-D heart printed four times and placed on display side by side and saying "this is a black heart, this is a white heart..." and ect demonstrating that were all human and race is only skin deep. I would like permission to use your 3-D heart in our exhibit. Its a free exhibit so no money will be profited from your 3D heart and it will not be sold, it will be used for display purposes only. And if you like I can send you pictures of the display using your 3D model in our exhibit when its done.
Thanks Melanie Prettyman.


Absolutely, use it for any non-profit use. That sounds like a great project. I'd love to see the makes.


Thank you! And is it okay if I know your last name so that I can credit you as the artist?

Brian Locicero is my full name. Thanks again for asking!

thankyou nice design with our perfect machine settings its coming out fine even with FDM....

Absolutely beautiful model. Printed with supports at 0.1mm resolution sliced by Simplify3D as a gift and it looks stunning. Incredibly accurate!
Thank you for the model!

Anatomical Heart

Thank you! Nice make.

How do I go about scaling it back up i need to put things inside of it

What setting would you use?

hello could explain how I can convert those MRI files into other 3D CAD program files? such as .stl or .stp

I didn't convert an MRI file. I sculpted it in ZBrush based on photo references.

hello! this looks fantastic.
I would like to make this... I'm curious if you have a file for second-extruder support material.

Sorry I do not.

Congrats! Your model has been featured as one of the Top 3D Printed Christmas / Holiday Models this year. Search "Top Free 3D Printed Christmas Gift 2015 Printing Ninja" to see. (sorry thingiverse bans URL addresses)

Awesome thanks! Searching that doesn't bring up any results though?

Can you please tell me about its wall thickness?


Where did you get a heart to 3d scan?

I didn't scan it. I modeled it in ZBrush while looking at a variety of anatomy references.

Yes, it's hollow. I had it printed by Shapeways so can't take credit.
