3D-printed biomaterial sleeves may reduce the risk of body piercing infections
- A startup in Canada is developing a biodegradable sleeve that will reduce the risk of infections brought by body piercing.
- This biomaterial sleeve will be used to cover piercing posts and release antiseptics slowly over a longer period of time.
- The first prototypes should be ready by this winter for field testing, and the startup hopes to have its first product commercially available in less than five years.
Virginia student uses 3D printed models to demonstrate mathematical concept of topology
- A student from James Madison University (JMU) in Virginia has 3D printed a series of objects that physically demonstrate the mathematical concepts of topology and homotopy.
- Traditionally, these concepts had been understood using two-dimensional diagrams and illustrations. In order to make it tangible, the student researcher designed it using Fusion360 and were 3D printed in collaboration with Shapeways.
Concept for 3-in-1 scanning, printing, and cutting cube unveiled
- A group of scientists from the Universidad Autonoma de Nuevo Leon in Mexico have proposed a “multifunctional cube like system” that combines scanning, dual-deposition 3D printing, stereolithographic laser treatment, and UV laser engraving.
- The scientists suggest that the concept could lead to the first commercial example of additive and subtractive functions on the desktop.
UK researchers continue work on Nanokick Bioreactor, progressing toward 3D printing living bone
- The University of Glasgow researchers have teamed up with other institutions across UK to continue work on the Nanokick bioreactor and the 3D printed bone research — the first time living bone has been grown in a laboratory setting.
- The bone is grown by sending nano vibrations across mesenchymal stem cells, found in human bone marrow, which have been suspended in collagen gel.
- The nanokick bioreactor is currently being tested for further clinical applications, like ‘switching off’ bone cancer cells, at other laboratories. In 2020, the UK research team’s innovative technique will be tested on humans, when an NHS plastic surgeon will add a little lab-grown bone into a patient’s hand.
Prellis Biologics receives funding to create human organs with 3D printing
- Wait lists for human organ transplants could be entirely eliminated through patent-pending technologies developed by Prellis Biologics, a San Francisco-based human tissue engineering company that has invented a new way to create viable human organs using near instantaneous 3D printing.
- Founded by two scientists with extensive experience in 3D tissue imaging and stem cell biology, the company is solving the greatest obstacle to producing functional human tissue in the lab – the ability to print microvasculature. Without the complex microvascular system needed to supply nutrients and oxygen to cells, an organ cannot survive.
Canadian researcher’s 3D bioprinted stem cell patch could ‘revolutionize’ heart disease treatment
- A researcher from the University of Saskatchewan is gaining attention for the development of a 3D bioprinted heart patch that could be used to re-grow and repair damaged heart tissue.
- This latest bioprinting breakthrough has so far been tested on animals with positive results.
- The nanoparticles in the 3D bioprinted scaffold prompt the stem cells (found in the patch) to transform into heart cells, which gradually helps to regenerate the patient’s own damaged heart, even helping to create new blood vessels.
