functional heart valve

Recommended Posts

Hi,

Is it possible to have 3D printable whole heart model with functional mitral valve. I would like to print it using silicon/ PVA to have the elasticity as close as the real heart.

The heart is possible, but the valves will be a hard call, which depends on the skill of the radiologist and the 3D modeller.  You can segment the cuspids on hand and hope for the best. Smaller slices, better result. The print will be also a hard call, unless you have a Polyjet on hand.

I agree. Even with polyjet, there is the issue of wall thickness. The leaflets are very thin and thus hard to print with any printing technology. With great difficulty I designed an 3D printed a customized sheep heart for flow testing of TAVR devices using elastic material.
