3D printing has allowed a team at the University of Adelaide to print the smallest scope ever made for imaging blood vessels. Here’s more from SlashGear:
Tiny endoscopes, such as the one the team has created, allow doctors to look inside the vessels to see how the plaque forms and explore new ways to treat it. The team was able to print complicated lenses that are too small to see with the naked eye using the 3D micro-printing technique. The entire endoscope, including its protective casing, is less than half a millimeter across.
We are angry, frustrated, and in pain because of the violence and murder of Black people by the police because of racism. We are in the fight AGAINST RACISM. George Floyd was murdered, his life stolen. The Adafruit teams have specific actions we’ve done, are doing, and will do together as a company and culture. We are asking the Adafruit community to get involved and share what you are doing. The Adafruit teams will not settle for a hash tag, a Tweet, or an icon change. We will work on real change, and that requires real action and real work together. That is what we will do each day, each month, each year – we will hold ourselves accountable and publish our collective efforts, partnerships, activism, donations, openly and publicly. Our blog and social media platforms will be utilized in actionable ways. Join us and the anti-racist efforts working to end police brutality, reform the criminal justice system, and dismantle the many other forms of systemic racism at work in this country, read more @ adafruit.com/blacklivesmatter
