Collagen is the primary component of the extracellular matrix in the human body. It has proved challenging to fabricate collagen scaffolds capable of replicating the structure and function of tissues and organs.We present a method to 3D-bioprint collagen using freeform reversible embedding of suspended hydrogels (FRESH) to engineer components of the human heart at various
Italian 3D printer manufacturer WASP has launched a free add-on for open source 3D modelling software Blender that allows users to model orthopedic devices with 3D scans. Designed for use by medical professionals, the add-on runs on Blender 2.8 and contains step-by-step commands to model a shape on a 3D scan, with the final design intended for 3D printing. The
In ‘Application of high resolution DLP stereolithography for fabrication of tricalcium phosphate scaffolds for bone regeneration,’ researchers examine how to make complex, stable scaffolds based on β-tricalcium. Typically, there are obstacles to finding materials and techniques suitable for creating structures capable of sustaining cell life. Here, the authors are aware of the necessities in tissue
Researchers from the University of Illinois at Chicago (UIC) have developed a scaffold-free 3D bioprinting process. Commonly, biodegradable scaffolds are used to maintain the shape of 3D bioprinted tissue used in regenerative medicine research. However, according to the study published in Materials Horizons, degradation byproducts within the scaffolds can be toxic as well as interfere with the development of cell-to-cell connections of functional tissues.
With 109 established bioprinting companies and many entrepreneurs around the world showing interest in the emerging field, it’s just a matter of time before it becomes one of the most sought after technologies. Mapping the companies that make up this industry is a good starting point to understand the bioprinting ecosystem, determine where most companies
Source NIH There’s considerable excitement that 3D printing technology might one day allow scientists to produce fully functional replacement organs from one’s own cells. While there’s still a lot to learn, this video shows just some of the amazing progress that’s now being made. The video comes from a bioengineering team at Rice University, Houston, that has
For people whose spinal cords are injured in traffic accidents, sports mishaps, or other traumatic events, cell-based treatments have emerged as a potential avenue for encouraging healing. Now, taking advantage of advances in 3D printing technology, researchers have created customized implants that may boost the power of cell-based therapies for repairing injured spinal cords. Made of
Scientists have successfully 3D printed a cornea utilizing a biocompatible bioink, composed of decellularized corneal stroma and stem cells, resulting in a replica with transparency similar to a human cornea. A collaborative team of engineering and medical scientists from the Pohang University of Science and Technology (Republic of Korea) have developed a strategy for 3D
In ‘Differential thermal analysis of the antibacterial effect of PLA-based materials planned for 3D printing,’ authors P. Maroti, B. Kocsis, A. Ferencz, M. Nyitrai, and D. Lorinczy explore the opportunities biomedical applications offer to research and medicine, along with the importance of evaluating materials used in creating devices. In this study, researchers are specifically concerned
Organovo Holdings, Inc. (NASDAQ:ONVO) (“Organovo”), a biotechnology company pioneering the development of 3D bioprinted tissues aimed at treating a range of serious diseases, today announced a collaboration with Professor Melissa Little at the Murdoch Children’s Research Institute (“MCRI”), The Royal Children’s Hospital, Melbourne, Australia and Ton Rabelink at Universiteit Leiden (“LUMC”), Leiden, Netherlands. The project will expand the use of 3D bioprinted stem
