Cardiac conduction system visualized using 3D printing
- Scientists at the Universities in the UK and Denmark have developed a new method of conceptualising the cardiac conduction system (CCS) using the 3D printing technology.
- This new technique will mean surgeons will be able to plan complex heart surgery in abnormal hearts without damaging precious tissue.
- The process works by soaking post-mortem samples in an iodine solution, which means that the soft tissues can absorb X-Rays and therefore become visible.
How to use real world problems to teach design thinking, 3D printing and collaboration
- The students worked with senior citizens to identify real world problems that could be addressed by designing and prototyping solutions.
- The Brookwood students used Play-Doh, cardboard, and duct tape to create prototypes of their proposed devices, before producing 3D-printed objects. The surprising collaboration led to some ingenious outcomes: a playing-card holder for someone with a bad rotator cuff; a bingo marker that is easy to pick up and move; and a bagel holder that makes slicing safer.
Researchers use laponite to improve 3D printing with hydrogels
- Most research teams interested in using hydrogels have persisted in learning to 3D print them because of the ability to customize items like implants, offering patient-specific devices that can be so much more effective.
- Three-dimensional printing of cell-laden hydrogels is still a challenge today, that is why researchers from Technische Universität Dresden and the University of Southampton has begun using Laponite, an artificial nanosilicate clay. With this material they are able to 3D print new scaffolds. The bioink is created through a combination of both alginate and methylcellulose which facilitate easier 3D printing
U.S. navy’s 3D printed CICADA drone is ready to drop
- Equipped with a 3D-printed fuselage, the U.S. Naval Research Laboratory’s (NRL) CICADA drone is ready for a commercial partner to take the technology to the next level.
- The CICADA MK5 is made using a single printed circuit board plate. The board is cut in a way that the device can be easily folded into an airborne 3D shape, and a 3D printed fuselage is used to keep the internal electronics secure.
Nonprofit Pawsthetics launches GoFundMe campaign to raise funds for 3D Printed Animal Prosthetics
- Pawsthetics has officially obtained its 501c3 nonprofit status this year to expand its reach and raise more money for animals that are victims of abuse, neglect, or disablement.
- The nonprofit organization has made good use of 3D CAD, 3D scanning, 3D printing, and even freehand design to develop functional prosthetics for animals.
