199 downloadsBreast cancer is the most commonly diagnosed cancer in women and one in eight women will be diagnosed with breast cancer in her lifetime. Each year it is estimated that over 230,000 women in the United States will be diagnosed with breast cancer and more than 40,000 will die. It is the second leading cause of death from cancer in women (lung cancer is the leading cause). Over 2.9 million breast cancer survivors are alive in the United States today. These STL files allow you to 3D print a whole breast with the mass within the breast and another model of just the mass. The models are provided for distribution on embodi3D.com with the permission of the creators Dr. Beth Ripley and Dr. Tatiana. These models are part of the Top 10 Killers 3D printable disease library. James Weaver and Ahmed Hosny also contributed to the project. We thank everyone involved for their contributions to embodi3d.com and their advocacy for better health and education through 3D printing. There are two STL files available for download and 3D bioprinting. One STL file for printing the breast including the cancerous mass and the other STL is for printing the mass. Both files have been zipped to reduce the file size. You will need to unzip the files once you have downloaded them.These files are distributed under the Creative Commons license Attribution-NonCommercial-NoDerivs. Please respect the terms of the licensing agreement. Both files are verified as watertight (manifold) and 3D printable.
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.
