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.

Carnegie Mellon University researchers develop low-cost open-source 3D bioprinter (Video)

3D bioprinter

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)”

Johnson & Johnson to open 3D bioprinting lab at Trinity College Dublin

3D bioprinting lab

AMBER, the Science Foundation Ireland-funded materials science institute headquartered at Trinity, today announced a new strategic collaboration with Johnson & Johnson Services, Inc. to establish a collaborative laboratory focused on 3D bioprinting.

Research projects will focus initially in orthopaedics and, in the long-term, offer its internal scientific experts as adjunct professors and engage in staff exchanges. The new Global Centre of Excellence for 3D bioprinting will transform healthcare delivery for patients and consumers. It is due to be operational by the end of 2018.

The announcement was welcomed by Minister for Business, Enterprise and Innovation, Heather Humphreys TD, who said: “Because of the fantastic success of the SFI Research Centre, AMBER, Ireland has a worldwide reputation for excellence in 3D bioprinting and is a global leader in materials science. I am delighted to welcome this new collaboration and look forward to its success moving forward.” Continue reading “Johnson & Johnson to open 3D bioprinting lab at Trinity College Dublin”

Brasil researchers to test 3D bioprinting in agriculture

Imitating nature in laboratories and manufacturing leaves, seeds, and even more complex structures of plants, animals or microorganisms could soon become a reality at Embrapa Genetic Resources and Biotechnology’s Laboratory of Nanobiotechnology (LNANO), in Brasília, DF, Brazil. The recent approval of a project, as well as other related activities, will enable researchers to test biological activities in three-dimensional environments, that is, closer to reality.

The project leader, the Embrapa researcher Luciano Paolino da Silva explains that the  technique used is called 3D bioprinting, a variant of 3D printing, a method to manufacture solid objects from a digital file containing spatial information and dimensional coordinates. The team intends to use the 3D bioprinting technology to create valid models and to test nanomaterials produced from biomolecules obtained from agricultural and forestry industry waste.  Continue reading “Brasil researchers to test 3D bioprinting in agriculture”

Moroni Lab – Largest European 3D bioprinting program launched by Maastricht University, Brightlands Materials Center

3D bioprinting program

Moroni Lab – Largest European 3D bioprinting program launched by Maastricht University, Brightlands Materials Center. It looks like Maastricht University is rapidly becoming one of Europe’s key centers for medical 3D printing efforts. Just this month, they spearheaded the new €4.6 million PRosPERoS project for 3D printed joint implant development, while researchers from Maastricht’s Moroni lab pioneered 3D bioprinted scaffolds that control stem cell differentiation.

New bioprinting technology to be developed by UMC Utrecht, regenHU (VIDEO)

bioprinting

New bioprinting technology to be developed by UMC Utrecht, regenHU. Partnering experts in 3D bioprinting with experts in biomanufacturing has resulted in the first melt electrospinning device that incorporates the use of bio-inks. Housed at the Utrecht Biofabrication Facility, this combination of techniques may lead to improved and more accurate 3D bioprinting for therapeutic use. The Utrecht Biofabrication Facility was established with support of Utrecht University and the UMC Utrecht in 2013.
