  1. Researches have been made on advancing the applications of 3D bioprinting. Thru this healthcare professionals are able to address complicated injuries and illnesses. The process of 3D bioprinting is utilized to generate tissues or living cells that help sustain growth and cell function within the printed cell or tissue. Patent on bioprinting was filed last 2003 and by 2006, it was then approved. It paved the way to more researches and encouraged hospitals and other research groups to continue experimenting on this type of process. Positive feedback are being received and it is a promising method to aid in reconstructive surgery and medical testing. 3D bioprinting started in different areas, however, Baltimore Maryland is now being seen as a hub for this type of method. This is due to a breakthrough research done at Johns Hopkins University’s Grayson Lab. Apart from that, it is also in Baltimore where you can find the world’s first 3D printing lab, called BUGSS or Baltimore Underground Science Space. It was created in 2012, by and for professional, citizen and amateur scientists and artists. This lab is their space and for them to further explore as well as learn more about the biotechnology world. The BUGSS have three 3D bioprinters. They make use of live stem cells from plants on their experiments and researches. Ryan Hoover, an artist and faculty member at the Maryland Institute College of Art is responsible for taking care of the lab and maintaining on-site bioprinters. Hoover is also using 3D bioprinters to experiment on plant material in order to create solutions wherein plant cells are able to recognize and merge into living tissues. The experiments and researches on bioprinting done at BUGSS are positive occurrences that will encourage forward the technological world of 3D bioprinting.
  2. The 3D printing technology provides revolutionary roles in the fast evolving field of medical technology. China-based company, Revotek, announced their custom-made 3D bioprinter that can print real blood vessels and other multiple layers of cells. What makes this news truly revolutionary is that no other commercially available 3D bioprinters have done this before. Yang Keng, Revotek’s chairman, noted that the company’s new 3D bioprinting system includes bio inks, medical imaging cloud platform, a 3D bioprinter, and a post processing system. With this new 3D printing system, it will now be easier to rebuild organs from scratch in the future. The heart of this new technology is the stem cell culture system called the Biosynsphere biological bricks that are developed to create personalized cells. It contains seed cells as well as bio inks to create layered cell structures with defined physiological functions. The new 3D printer works by alternately extruding bio inks, thus, it can create 10cm-long blood vessels under two minutes. The bio ink, on the other hand, is kept under special biological and environmental conditions so that the printer does not only make blood vessels but also various types of cells as well. But perhaps the most important component of this new 3D bioprinting system is the medical imaging cloud platform which will be available to all hospitals in China. This makes it easier for doctors and medical researchers to deal with bottleneck problems when it comes to treating different conditions using 3D bioprinted organs. With this new revolution, 3D printing can pave the way for better medical procedures for patients who require organ transplants.
  3. 3D bioprinting is a process of creating spatially-controlled cells using 3D printers. There are many uses of this particular technology which includes the use of 3D printers to make stem cells and building body parts to replace damaged ones. It is one of the most important engineering tools brought into the field of medical technology. One of the most recent and interesting use of 3D bioprinting is on breast cancer research. Researchers from the Texas Medical Center created in vitro models of breast cancer by magnetically levitating the cancer cells using a commercial 3D bioprinting system. By levitating the cell cultures, the research team conducting this study was able to replicate the tumor cells in a micro-environment with ease. With this technology, using 3D bioprinters allow researchers to form large-sized models within a few hours, mimic the tumor microenvironment and test the drug efficiency in a model that is compatible with the in vivo (natural environment) of the cancer cells. With the magnetically levitated 3D bioprinted cancer cells, the researchers also have control over the tumor density as well as composition. This gives researchers a lot of opportunities to test different environmental factors of the cancer cells and help them better understand it—which hopefully would lead to a cure. The research provides a better model of the breast cancer which signifies a very important breakthrough when it comes to studying cancer cells outside the body. Without 3D bioprinting, it is difficult to culture cancer cells in conditions outside the host. With this technology, it opens new doors of possibilities for future researchers to develop new and effective treatment modalities for cancer.
