Bioprinting

The second-generation PrintAlive bioprinter that produces skin grafts for burn victims on ...

While most are familiar with the potential for 3D printers to pump out plastic odds and ends for around the home, the technology also has far-reaching applications in the medical field. Research is already underway to develop 3D bioprinters able to create things as complex as human organs, and now engineering students in Canada have created a 3D printer that produces skin grafts for burn victims.  Read More

Scientists have come a step closer to being able to 3D-print biological tissue with integr...

The ability to bio-print tissues and organs could one day allow us to create custom body parts that could be used for transplants. New research has brought that possibility one step closer to reality. Scientists have bio-printed artificial vascular networks that mimic the body's circulatory system.  Read More

The researchers used three specially developed inks that borrow biological properties from...

The notion of 3D printed biological tissue holds all kinds of possibilities for drug testing and the reparation of damaged cells, though replicating the complexities of human tissue in a lab presents some very big challenges. A new bioprinting method developed by researchers from the Wyss Institute for Biologically Inspired Engineering at Harvard University has enabled the creation of tissue constructs with small blood vessels and multiple cell types, marking important progress toward the printing of living tissue.  Read More

A 3D printer built at Oxford University can produce droplet networks capable of folding in...

While the prospect of 3D printers pumping out biological tissues and replacement organs has many justifiably excited, researchers at Oxford University have gone in a slightly different direction with the creation of a custom 3D printer capable of producing synthetic materials that have some of the properties of living tissues. Rather than being intended for supplying spare parts for damaged replicants, the new materials could be used for drug delivery or replacing or interfacing with damaged tissues inside the human body.  Read More

When a child is born with the congenital deformity known as microtia, they have an underdeveloped external ear – also known as the pinna. Even though their inner ear may be normal, the lack of the external structure can affect their hearing, plus it looks unusual. Normally, a replacement pinna is made from a foam-like material (or sometimes even cartilage from the rib cage) and implanted under the skin, although these don’t always look particularly natural. Now, scientists from Cornell University have developed a more realistic pinna grown from biological material, using a 3D printer.  Read More

The RepRap printer, using molten sugar to create the vascular network's mold and filaments...

For a great number of people, the idea of being able to use a patient’s own cells to create lab-grown replacement organs is very appealing. Already, researchers have had success growing urethras (which are essentially hollow tubes), and miniature human livers. Before large, solid, three-dimensional organs can be grown, however, scientists must figure out a reliable way of incorporating blood vessels into them – if the lab-grown organs simply take the form of a block of cells, the cells on the inside won’t be able to receive any nutrients, and will die. Now, a team from the University of Pennsylvania and MIT has devised a way of building such vessels, using sugar.  Read More

Using a modified HP DeskJet 500 printer, researchers at Clemson University have discovered...

Old inkjet printers are an important tool for bioprinting. Recently, researchers from Clemson University discovered that inkjet bioprinting disrupts the membranes of the cells being printed, leaving them open to having proteins inserted ... and opening up new avenues of research in the field.  Read More
