About This File

This 3D printable model of a human heart was generated from a contrast enhanced CT scan.  This model is an improvement over a prior version (here). It shows the heart with slices cut in the anatomical transverse plane. If you are interested in a heart with short-axis slices, check out my short-axis stackable slice model here.

Notches have been added to ensure the slices fit together and do not slide against each other. The model demonstrates the detailed anatomy of the human heart in exquisite detail. Each slice stacks on top of the prior slice to form a complete human heart. Individual slices show the detailed cardiac anatomy of the right and left ventricles, and right and left atria, and outflow tracts. Perfect for educational purposes. It has been validated as printable on an Ultimaker 3 Extended printer.

I've printed this model many times, both in PLA and using stereolithography resin. The images below are an example using polished clear resin that the embodi3D service uses. Make sure to use adequate support for the fine structures inside the heart chamber and it should turn our great. 


If you don't want to print it yourself, you can order it printed through the embodi3D print service.

We 3D printed this model for a customer and the print turned out beautifully. The parts stack nicely and by opening them up, you can clearly see the detailed structures inside the heart chambers. To learn more about our 3D printing service, click here.





Here is another print we did in flexible material at 2/3 scale, as requested by the customer. The flexible material has a soft, rubbery feel that is very nice to handle.
