3D printing in nanofabrication could make processes cheaper, faster, and reduce waste. Armed with pre-patterned substrates and 3D printing technology, researchers may be able to realize new complexity in nanoscale 3D fabrication. The most recent development in 3D printing on the nano-scale comes from a team led by Ho-Young Kim, a professor at Seoul National University in South Korea.
Electrospinning is a technique which uses an electrical charge to draw a micro or nano-scale fibers from a liquid. It’s a relatively cheap and easy way to produce polymer nanojets which may be used to create nanoscale fibers. According to professor Kim, nano-scale fiber streams are often so chaotic that it is difficult – if not impossible – to control individual fibers. In their recent work such nano-scale fiber streams are kept in relative order using a thin metal electrode line.
Using this line, the polymer nanojet may be stacked to form a wall-like structure. The team showed that tension in the polymer fiber may be balanced using the electrostatic interaction of the fiber and a metal ground, and that the length of a nanowall may be controlled translating the substrate….
Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!
Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!
The Adafruit Learning System has dozens of great tools to get you well on your way to creating incredible works of engineering, interactive art, and design with your 3D printer! We also offer the MakerBot Digitizer in our store. If you’ve made a cool project that combines 3D printing and electronics, be sure to let us know, and we’ll feature it here!
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
