First human corneas have been 3D printed by scientists at Newcastle University
It means the technique could be used in the future to ensure an unlimited supply of corneas. As the outermost layer of the human eye, the cornea has an important role in focusing vision.
Yet there is a significant shortage of corneas available to transplant, with 10 million people worldwide requiring surgery to prevent corneal blindness as a result of diseases such as trachoma, an infectious eye disorder.
In addition, almost 5 million people suffer total blindness due to corneal scarring caused by burns, lacerations, abrasion or disease. Continue reading “First human corneas have been 3D printed by scientists at Newcastle University (Video)”
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.

New method for 3D printing biological samples enables faster, cheaper models for research & diagnosis
What if you could hold a physical model of your own brain in your hands, accurate down to its every unique fold? That’s just a normal part of life for Steven Keating, Ph.D., who had a baseball-sized tumor removed from his brain at age 26 while he was a graduate student in the MIT Media Lab’s Mediated Matter group. Curious to see what his brain actually looked like before the tumor was removed, and with the goal of better understanding his diagnosis and treatment options, Keating collected his medical data and began 3D printing his MRI and CT scans, but was frustrated that existing methods were prohibitively time-intensive, cumbersome, and failed to accurately reveal important features of interest. Keating reached out to some of his group’s collaborators, including members of the Wyss Institute at Harvard University, who were exploring a new method for 3D printing biological samples.

Additive manufacturing a novel titanium dental implant abutment – Presented by Les Kalman, Research Driven at the 3D Medical Printing Conference, which will take place on 30-31 January 2019 at MECC Maastricht, The Netherlands.
Dental implants are an important elective option for the replacement of a missing tooth or teeth. The abutment acts as an interface between the implant and artificial tooth/teeth. A novel dental implant abutment, that provides a simple, efficient and inexpensive alternative for tooth fabrication, has been developed, patented and termed Tempcap.
The initial (traditional) prototype was fabricated by laser welding components but resulted in a weak structure with excessive variability in design. Manufacturing through conventional machining proved too costly and complicated. Additive manufacturing was investigated as an alternative to fabrication. The prototype was digitized and refined through CAD and initially printed in Duraform 316L stainless steel. The prototypes were qualitatively assessed for functionality by implant threading and successful simulated fabrication of an artificial tooth in a laboratory setting.
Based on the final optimized design, Tempcaps were 3D printed in dental-grade Titanium (Ti-6Al-4V) (ADEISS, London, ON). Complimentary to the 3D printing process, all Tempcaps underwent post-processing, which included final thread tapping for pronounced thread geometries, heat treatment for relieving thermal stresses and strengthening, and bead blasting for a smoother finish.
The final research objectives are: (1) to compare the maximum torques experienced during insertion of conventional and 3D printed Tempcaps into dental implants and (2) to assess the mechanical strength of the retentive pin projections under compression.
Results will be obtained this summer. The research will provide the necessary results required to verify and validate the 3D printed Tempcap for a clinical assessment. Continue reading “Additive manufacturing a novel titanium dental implant abutment – Presented by Les Kalman, Research Driven”
Smart Material Applications in Dentistry – Presented by Sherif Kandil, K Line at the 3D Medical Printing Conference, which will take place on 30-31 January 2019 at MECC Maastricht, The Netherlands.
The greatest scientific discovery of humanity was the discovery of knowledge. Once humans realized how little they knew about the world, they suddenly had a very good reason to seek new knowledge, which opened up the scientific road to progress.

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.
