Portable 3D skin printer to heal deep wounds, developed by University of Toronto researchers
University of Toronto researchers have developed a handheld 3D skin printer that deposits even layers of skin tissue to cover and heal deep wounds. The team believes it to be the first device that forms tissue in situ, depositing and setting in place, within two minutes or less.
The research, led by PhD student Navid Hakimi under the supervision of Associate Professor Axel Guenther of the Faculty of Applied Science & Engineering, and in collaboration with Dr. Marc Jeschke, director of the Ross Tilley Burn Centre at Sunnybrook Hospital and professor of immunology at the Faculty of Medicine, was recently published in the journal Lab on a Chip.
For patients with deep skin wounds, all three skin layers – the epidermis, dermis and hypodermis – may be heavily damaged. The current preferred treatment is called split-thickness skin grafting, where healthy donor skin is grafted onto the surface epidermis and part of the underlying dermis.

Researchers at Carnegie Mellon University have developed a low-cost 3D bioprinter by modifying a standard desktop 3-D printer, and they have released the breakthrough designs as open source so that anyone can build their own system. The researchers—Materials Science and Engineering (MSE) and Biomedical Engineering (BME) Associate Professor Adam Feinberg, BME postdoctoral fellow TJ Hinton, and Kira Pusch, a recent graduate of the MSE undergraduate program—recently published a paper in the journal HardwareX that contains complete instructions for printing and installing the syringe-based, large volume extruder (LVE) to modify any typical, commercial plastic printer.
“What we’ve created,” says Pusch, “is a large volume syringe pump extruder that works with almost any open source fused deposition modeling (FDM) printer. This means that it’s an inexpensive and relatively easy adaptation for people who use 3-D printers.” Continue reading “Carnegie Mellon University researchers develop low-cost open-source 3D bioprinter (Video)”
3D printing is seeing increasingly widespread adoption in the medical field, with numerous examples of applications that help surgeons accurately plan cosmetic surgery. Now, the potential of 3D printing is being examined by hospitals treating patients who are fighting for their life.
The ETZ (Elisabeth-TweeSteden Ziekenhuis) is one of the eleven trauma centers in the Netherlands. As the only center in the country with trauma surgeons on location 24 hours a day, it serves as the main location for emergency patients in North Brabant. 3D printing has already been used to visualize bone fractures, but pioneering researchers believe it can also be used to help treat trauma patients.
Mike Bemelman, MD, trauma surgeon at the ETZ, had already seen the potential of 3D printing back in 2016. Together with Lars Brouwers, MD, PhD-candidate, and Koen Lansink, MD, trauma surgeon, they have started conducting research into the benefits and effectiveness of 3D printing, compared to traditional and other new technologies. Their idea is to 3D print scanned bone fractures in order to give both surgeons and patients a clear understanding of each situation, before operating.

New 4D Printing technique developed by TU Delft researchers has potential to improve bone implants
Researchers at TU Delft have combined origami techniques and 3D printing to create flat structures that can fold themselves into 3D structures (for example a tulip). The structures self-fold according to a pre-planned sequence, with some parts folding sooner than others. Usually, expensive printers and special materials are needed for that. But the TU Delft scientists have created a new technique that requires only a common 3D printer and ubiquitous material. Among other applications, their research has the potential to greatly improve bone implants.
In recent years, Amir Zadpoor of TU Delft has become somewhat of an origami master. His team’s work combines the traditional Japanese paper folding art with the more novel technology of 3D printing in order to create constructs that can self-roll, self-twist, self-wrinkle and self-fold into a variety of 3D structures. In 2016, the researchers already demonstrated several self-folding objects. ‘But there were still serious challenges we needed to address’, says Zadpoor.

ETH researchers from the Functional Materials Laboratory have developed a silicone heart that beats almost like a human heart. In collaboration with colleagues from the Product Development Group Zurich, they have tested how well it works.
It looks like a real heart. And this is the goal of the first entirely soft artificial heart: to mimic its natural model as closely as possible. The silicone heart has been developed by Nicholas Cohrs, a doctoral student in the group led by Wendelin Stark, Professor of Functional Materials Engineering at ETH Zurich. The reasoning why nature should be used as a model is clear. Currently used blood pumps have many disadvantages: their mechanical parts are susceptible to complications while the patient lacks a physiological pulse, which is assumed to have some consequences for the patient.

Researchers are 3D printing replica human vertebrae to help in surgery room
A project led by Nottingham Trent University aims to give trainee surgeons the “tacit knowledge” of how it feels to partly remove or drill into vertebrae before undertaking procedures on patients.
The models – which are created using powder printing technology to help achieve a lifelike porosity of real bone – feature hard outer layers and a softer centre.
“Consultants undertaking delicate and precise procedures like spinal surgery need as much knowledge and experience as possible as part of their surgical training before going into live operations,” said Professor Philip Breedon, of the university’s Design for Health and Wellbeing Group.
“One error can lead to catastrophic, life-changing consequences for a patient, so it’s imperative that surgeons can prepare themselves thoroughly. Continue reading “Researchers are 3D printing replica human vertebrae to help in surgery room (Video)”

New method to 3D Print laboratory-grown cells to form living structures, developed by Oxford researchers
The approach could revolutionise regenerative medicine, enabling the production of complex tissues and cartilage that would potentially support, repair or augment diseased and damaged areas of the body.
Printing high-resolution living tissues is hard to do, as the cells often move within printed structures and can collapse on themselves. But, led by Professor Hagan Bayley, Professor of Chemical Biology in Oxford’s Department of Chemistry, the team devised a way to produce tissues in self-contained cells that support the structures to keep their shape.
The cells were contained within protective nanolitre droplets wrapped in a lipid coating that could be assembled, layer-by-layer, into living structures. Producing printed tissues in this way improves the survival rate of the individual cells, and allowed the team to improve on current techniques by building each tissue one drop at a time to a more favourable resolution.
