Thomas Boland
He was the first to retrofit a standard inkjet
printer and use cells as ink. By printing layer
by layer he could achieve 3D printing of
organs by 2003
Chief Science Officer and co-
founder of TeVido BioDevices
in association with Clemson
University, Dr. Boland’s work
has been cited more than 800
times. He has received
numerous awards.
How is 3D printing done now?
•
Series of successive slices of CT scan or
MRI are made
•
These are converted into layers of
plastic, ceramic, glass or even tissue
•
They are constructed into ‘graspable’
3D digital models
Potential uses of
3D Models in Medicine
•
Exact simulation and better
understanding of structural pathology
& anatomy
•
Appreciation of tissue planes for
dissection
•
Demonstration & Teaching
Potential uses
•
Models of fetus in utero to assess
anomalies
•
Depiction of fascial planes for dissection
& repair (eg. Perineal repair)
•
Depiction of injuries (eg. Ureteric injury)
•
Precise models of lesions, tumors etc
•
Pre operative surgical planning
•
Education of patients
•

Many internal organs were shared
(chest wall, lungs, pericardial sac,
diaphragm, liver, intestines, colon
and pelvis).
Using 3D printing the twin organs
were printed showing all the parts
in detail which helped in
separation of twins.

For the uninitiated in the audience, ObG watch is a brief update of what is happening in the field of ObG and our sister disciplines around the globe. I have been making these presentations since the year 2000.
Explore the groundbreaking applications of 3D printing in the medical field, from creating custom implants and prosthetics to precise surgical planning and educational models. Dr. Thomas Boland's pioneering work in organ printing and the current process of 3D printing using CT or MRI scans are highlighted. Discover how this technology revolutionizes medical training, patient care, and surgical interventions.

Tokyo researchers have successfully taken goat fetuses and put them in synthetic wombs for continued gestation! The fetuses have stayed in the environment for up to three weeks, but Yoshinori Kuwabara, chairman of the Department of Obstetrics and Gynecology at Juntendo University in Tokyo, has said that this can be extended or applied to human beings! Ectogenesis was a term created by British scientist J. B. S. Haldane in 1924. #science #biology Ectogenesis Japanese researchers have grown a goat embryo inside a 3D printed uterus
