The Swiss researcher print a soft heart by 3D print
technology which is highly similar to the true one
on shape、size and function. Though this man made he-
art is still on testing and can’t be applied in tr-
ansplant,it provides a new idea about solve related
problems.
This human made heart is made from soft silica gel,
with help of 3D printing and investment casting tec-
hnology. Weight 390g and 679 cubic CM.
The construct of this man made heart is a complex
silica gel, include a ventriculus dexter and ventr-
iculus sinister and an extra room to separate two
ventricles, this room plays like muscle to drive the
blood in and out heart.
At present, the man-made blood pump can dive our bl-
ood,but the mechanical parts can blight us as well.
The researcher said: “ they want to make a similar
heart exact as ours. “
This 3D print heart is on testing and due to the limi
-ted of raw material, this heart can only beat 3000
times, in other word, it can continue working only
30~45 minutes. We still need to find a much better
material to solve the problem of tensile strength and
functions, but this new direction is great.
Some times its a pain in the ass to read what website owners wrote but this site is rattling user pleasant! . quality system audits
