Multinozzle printer can switch between multiple inks up to 50 times per second 3D printers are revolutionizing manufacturing by allowing users to create any physical shape they can imagine on-demand. However, most commercial printers are only able to build objects from a single material at a time and inkjet printers that are capable of multimaterial
A novel bioink can integrate living cells into 3D scaffolds at a speed of one meter per second, making it possible to study the spread of diseases and produce tailor-made tissue. 3D bioprinting has come a long way in recent years, with scientists using living tissue to print organs as complex as human skin. Researchers in
Liquid-in-liquid 3D printing was first presented in a BMW funded MIT project. Although the project initially seemed limited in scope the possibilities of 3D printing within a liquid medium opens new opportunities in terms of escaping gravitational pull and thus producing parts that require a more volumetric approach, such as biological structures and organs. As reported
Development is significant step toward skin grafts that can be integrated into patient’s skin Researchers at Rensselaer Polytechnic Institute have developed a way to 3D print living skin, complete with blood vessels. The advancement, published online today in Tissue Engineering Part A, is a significant step toward creating grafts that are more like the skin our bodies
With a new process developed at TU Wien (Vienna), living cells can be integrated into fine structures created in a 3D printer – extremely fast and with very high resolution. Tissue growth and the behavior of cells can be controlled and investigated particularly well by embedding the cells in a delicate 3D framework. This is
3D-printed thick vascularized tissue constructs for organ engineering and regenerative medicine In this video, the Wyss Institute and Harvard SEAS team uses a customizable 3D bioprinting method to build a thick vascularized tissue structure comprising human stem cells, collective matrix, and blood vessel endothelial cells. Their work sets the stage for advancement of tissue replacement
In the recently published, ‘Hydroxyapatite Structures Created by Additive Manufacturing with Extruded Polymer,’ Katherine Vanesa López Ambrosio (School of Advanced Materials Discovery / Colorado State University at Fort Collins) tackles 3D printed implants for bone regeneration. While surgeons have been using conventional implants with some success, there is always a risk of infection and the potential
In ‘Synthesis, characterization and 3D printing of linear and star-shaped poly(propylene fumarate) for medical applications,’ Yuanyuan Luo offers a PhD dissertation for The University of Akron on the subject of additive manufacturing and new polymer synthetics for use in the medical realm. As materials science continues to expand, researchers are drawn to exploring the uses of 3D
The School of Engineering and Applied Science announced late last month that a mechanical and aerospace engineering professor received $300,000 from the American Heart Association to develop a device that can print tissue used for repairing heart damage. The AHA – a nonprofit organization that funds cardiovascular research – granted a three-year award to Lijie
Biofabrication holds great potential to revolutionize important industries in the health, food, and textile sectors, but its translation to market is still challenging. Pedro F. Costa in a paper newly published on Trends in Biotechnology analyzes the current state of innovation and commercialization in biofabrication and try to assess its limitations, strengths, and future progress.
