Graphene micro supercapacitors enhance flexibility and performance in wearable technology

Posted by in categories: 3D printing, augmented reality, computing, wearables

The proliferation of wearable devices—from smart watches to AR glasses—necessitates ever-smaller on-board energy solutions that can deliver bursts of power while remaining unobtrusive.


Scientists leverage additive-free 3D printing process to construct exceptionally customizable and high-performing graphene-based micro-supercapacitors tailored for on-chip energy storage.

Engineers 3D print the electromagnets at the heart of many electronics

Posted by in categories: 3D printing, biotech/medical

Imagine being able to build an entire dialysis machine using nothing more than a 3D printer.

This could not only reduce costs and eliminate manufacturing waste, but since this machine could be produced outside a factory, people with limited resources or those who live in remote areas may be able to access this more easily.

While multiple hurdles must be overcome to develop that are entirely 3D printed, a team at MIT has taken an important step in this direction by demonstrating fully 3D-printed, three-dimensional solenoids.

Researchers 3D print functional human brain tissue with active neural networks

Posted by in categories: 3D printing, biotech/medical, robotics/AI

Researchers from the University of Wisconsin-Madison (UW-Madison) have developed a novel approach for 3D printing functional human brain tissue.

The 3D printing process can create active neural networks in and between tissues that grow in a matter of weeks.

The researchers believe that their 3D bioprinted brain tissue provides an effective tool for modeling brain network activity under physiological and pathological conditions, and can also serve as a platform for drug testing.

Fluicell partners with Swedish researchers to 3D bioprint complex brain cell structures

Posted by in categories: 3D printing, bioprinting, biotech/medical, neuroscience

Scientists from medical tech company Fluicell have partnered with clinical R&D firm Cellectricon and the Swedish Karolinska Institutet university to 3D bioprint neural cells into complex patterns.

Using the microfluidic printheads featured on Fluicell’s Biopixlar platform, the researchers were able to accurately arrange rat brain cells within 3D structures, without damaging their viability. The resulting cerebral tissues could be used to model the progress of neurological diseases, or to test the efficacy of related drugs.

“We’ve been using Biopixlar to develop protocols for the printing of different neuronal cells types, and we are very pleased with its performance,” said Mattias Karlsson, CEO of Cellectricon. “This exciting technology has the potential to open completely new avenues for in-vitro modeling of a wide range of central and PNS-related diseases.”

Scientists create new laser-based method to 3D-print artificial cartilage

Posted by in categories: 3D printing, biotech/medical

A new laser-based approach has been introduced to produce artificial cartilage using 3D printing technology.

In this approach, researchers from TU Wien printed living cells within tiny football-like spheroids.

The team hopes this technique could be used to cultivate lab-grown tissue capable of replacing damaged cartilage in humans. It is a strong connective tissue found in various parts of the body that protects our joints and bones.

This new 3D printing method could solve the organ transplantation crisis

Posted by in categories: 3D printing, bioengineering, biotech/medical

In the United States, the shortage of available organs for transplantation remains a critical issue, with over 100,000 individuals currently on the waiting list. The demand for organs, including hearts, kidneys, and livers, significantly outweighs the available supply, leading to prolonged waiting times and often, devastating consequences.

It is estimated that approximately 6,000 Americans lose their lives while waiting for a suitable donor organ every year.

Researchers at Carnegie Mellon University have developed a novel tissue engineering technique that aims to potentially bridge the gap between organ demand and availability, offering a beacon of hope.

Photos: World’s tallest 3D-printed tower set to be built in Swiss Alps

Posted by in categories: 3D printing, innovation

The world’s tallest 3D-printed tower, set to be built in the Swiss Alps along the Julier mountain pass, started fabrication at ETH in Zurich this month.

Tor Alva, also known as the “White Tower,” is a pioneering innovation in the 3D printing industry illustrating a 30-meter tall building in Mulegns, Switzerland.

The White Tower project was led by Benjamin Dillenburger and launched in collaboration with Fundaziun Origen.

Scientists 3D Print Functional Human Brain Tissue

Posted by in categories: 3D printing, biotech/medical, neuroscience

A team of scientists at the University of Wisconsin-Madison claim to have 3D-printed functional human brain tissue for the first time.

They hope their research could open the doors for the development of treatments for existing neurological disorders, including Alzheimer’s and Parkinson’s disease.

As detailed in a new paper published in the journal Cell Stem Cell, the team flipped the usual method of 3D-printing on its side, fabricating horizontal layers of brain cells encased in soft “bio-ink” gel.
