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.

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)”

VTT Finland is developing 3D technology for wound care
Cellulose nanofibrils have properties that can improve the characteristics of bio-based 3D-printing pastes. VTT Technical Research Centre of Finland is developing a 3D wound care product for monitoring wound condition in hospital care. However, the first commercial nanocellulose applications will be seen in indoor decoration elements, textiles and the production of mock-ups.
3D printing has proven to be an efficient manufacturing method for complex, customised and light structures. In addition to thermoplastics, 3D printing materials include metals, ceramics and foodstuffs. The range of biomaterials in 3D paste printing is still fairly limited, since pastes pose unique challenges: their structure must not collapse during printing and the objects manufactured must remain sufficiently strong, rigid or flexible after drying. In 3D biomaterial filaments, however, commercial products already exist. Continue reading “VTT Finland is developing 3D technology for wound care”
US researchers develop technology that can 3D print drugs on wide variety of surfaces
A technology that can print pure, ultra-precise doses of drugs onto a wide variety of surfaces could one day enable on-site printing of custom-dosed medications at pharmacies, hospitals and other locations. Because the technique can print multiple medications into a single dose on a dissolvable strip, microneedle patch or other dosing device, it could make life easier for patients who today must take multiple medications every day. The work could also have important implications for the drug development process.
A team of University of Michigan researchers, in a study lead by materials science and engineering professor Max Shtein and U-M graduate researcher Olga Shalev, Continue reading “US researchers develop technology that can 3D print drugs on wide variety of surfaces (Video)”
