Organ model could improve surgical outcomes for thousands of patients worldwide. Researchers from the University of Minnesota, with support from Medtronic, have developed a groundbreaking process for multi-material 3D printing of lifelike models of the heart’s aortic valve and the surrounding structures that mimic the exact look and feel of a real patient.

These patient-specific organ models, which include 3D-printed soft sensor arrays integrated in...

Superior ‘Bio-Ink’ for 3D Printing pioneered

This 3D printing system would print gel scaffolds, or support structures, for growing human tissues. The system would include hyaluronic acid and polyethylene glycol as the basic “ink cartridges” and other cartridges featuring inks with different cells and ligands that serve as binding sites for cells.

Researchers are developing materials to help grow human tissues. Rutgers biomedical engineers have developed a “bio-ink” for 3D printed materials that could serve as scaffolds for growing human tissues to repair or replace damaged ones in the body.

Bioengineered tissues show promise in regenerative, precision and personalized medicine; product development; and basic research, especially with the advent of 3D printing of biomaterials that could serve as scaf...

Step toward ‘Ink’ development for 3D Printing a Bioprosthetic Ovary

Schematic of (a) processing the porcine ovary with a tissue slicer, prior to qPCR analysis, decellularization then proteomics analysis and iPCR validation. (b) Ovaries were sliced axially and sagittally. SDS, sodium dodecyl sulfate; decell’ed, decellularized; LC MS/MS, liquid chromatography tandem mass spectrometry; iPCR, immuno PCR.

Findings a huge step forward in fertility preservation and hormone restoration. For the first time, scientists identified and mapped the location of structural proteins in a pig ovary. Ongoing development of an “ink” with these proteins will be used for 3-D printing an artificial (or bio-prosthetic) ovary that could be implanted and allow a woman to have a child...

Honey, I Shrunk Michelangelo’s David

Researchers have reproduced Michelangelo’s David as a miniature in metal. Their achievement highlights the potential of a special 3D printing method. There he is, standing upon his pedestal: David by Michelangelo. A world-famous statue that nearly every child can recognise. But this David is just 1 millimeter tall, pedestal included, and is made not of marble like the 5.17-meter original, but of pure copper.

It was created using 3D printing by Giorgio Ercolano from Exaddon, an offshoot of ETH spin-off Cytosurge, together with the team led by ETH Professor Tomaso Zambelli from the Laboratory of Biosensors and Bioelectronics...
