Scientists have taken a major step towards the 3D-printing of replacement organs. A new technique for bioprinting tissues allows scientists to create vascular networks like those used in the body to transport blood, air, and other fluids.

3D-printing organs moves a few more steps closer to commercialization

New successes in printing vascular tissue from living cells point to the accelerating pace of development of 3D printing tissue — and eventually the ability to manufacture organs from small samples of cells.

Late last month Prellis Biologics announced a $8.7 million round of funding and some significant advancements that point the way forward for 3D printed organs while a company called Volumetric Bio based on research from a slew of different universities unveiled significant progress of its own earlier this year.

Miller has launched a startup to commercialize the research called Volumetric Bio. While the researchers have made their findings freely available through open source licenses, they’re hoping to commercialize the technology by selling their bioprinters and materials and reagents.

Scientists bioprint living tissue in a matter of seconds

Soon, though, it might be a matter of crafting whatever you need when you need it. Scientists at EPFL and University Medical Center Utrecht have developed an optical system that can bioprint complex, highly viable living tissue in "just a few seconds." It would represent a breakthrough compared to the clunky, layer-based processes of today.

The approach, volumetric bioprinting, forms tissue by projecting a laser down a spinning tube containing hydrogel full of stem cells. You can shape the resulting tissue simply by focusing the laser's energy on specific locations to solidify them, creating a useful 3D shape within seconds. After that, it's a matter of introducing endothelial cells to add vessels to the tissue.
While this definitely isn't ready for real-world use, the applications are fairly self-evident. EPFL imagines a new wave of "personalized, functional" organs produced at "unprecedented speed.

Harvard scientists have found a better way to 3D print organs

Amrita Khalid, @askhalid 06 Sep 2019
Scientists have experimented with growing organs in labs for years, but we're still years away from the technology being ready. Lab-grown organs are often too small for human use and lack an efficient mechanism for delivering oxygen. A group of scientists at Harvard's Wyss Institute have now developed a solution that will 3D print blood vessels on living tissues. Their paper, published today in Science Advances, explains how a new technique called the SWIFT method (Sacrificial Writing Into Functional Tissue), will enable the creation of larger, more effective organs.

Chicago biotech company 3D prints a mini human heart
BIOLIFE4D used patient-derived cardiac cells to 3D print the tiny heart
September 9, 2019
https://www.engadget.com/2019/09/09/biolife4d-3d-bioprints-mini-human-heart/

The Chicago-based biotech company BIOLIFE4D announced today that it has successfully 3D-bioprinted a mini human heart. The tiny heart has the same structure as a full-sized heart, and the company says it's an important milestone in the push to create an artificial heart viable for transplant.

The heart was printed with patient-derived cardiac muscle cells, or cardiomyocytes, and bioink made from extracellular matrix compounds that replicate the properties of the mammalian heart. BIOLIFE4D first bioprinted human cardiac tissue in June 2018.
Eventually, the company hopes to bioprint a full-sized functioning human heart.

Stratasys launches J750 Digital Anatomy 3D printer for ultra-realistic medical models
October 7, 2019
https://www.3dprintingmedia.network/stratasys-j750-digital-anatomy-3d-printer/

Stratasys has introduced a new 3D printer model, the J750 Digital Anatomy system, targeted squarely at the medical industry. The 3D printer leverages the company’s existing multi-material PolyJet 3D printing technology to produce 3D printed anatomical models that are ultra-realistic in terms of feel, responsiveness and biomechanics.

The 3D printer will enable medical professionals to produce increasingly accurate anatomical models that can be used for surgical planning and medical training.

“We believe in the potential of 3D printing to provide better health care, and the Digital Anatomy 3D Printer is a major step forward,” said Eyal Miller, Stratasys Healthcare Business Unit Head.
Stratasys has also released a series of new materials to go with the J750 Digital Anatomy 3D printer, including TissueMatrix, GelMatrix and BoneMatrix, which are suitable for mimicking cardiac, vascular and orthopedic structures, respectively.
