The research team at the University of Minnesota in the United States recently used a portable 3D printer to print electronic products on human hands. This new technology will not only help soldiers quickly print the electronic equipment needed on the battlefield, but also hope to provide new methods for wound healing and skin disease treatment.
The research results were published in the new issue of "Advanced Materials" magazine. The researchers implemented this technology using customized low-cost 3D printers. With new technology, soldiers on the battlefield can print temporary sensors on their bodies to detect chemical or biological agents, and they can also print solar cells to charge electronic devices.
"We are excited about the potential of this new 3D printing technology, which uses a lightweight printer that costs less than $ 400," said the study ’s lead author Michael McAlpin, an associate professor of mechanical engineering at the University of Minnesota. It's like a future 'Swiss army knife' that uses portable 3D printing tools to bring everything together. "
The key to the new technology is that it can adapt to the tiny movements of the body when printing. After making temporary marks on the skin and scanning, the 3D printer can use computer vision to track and adjust these marks in real time. In this way, during the printing process, even if the human body has some subtle movements, it can ensure that the printed circuit shape is not affected.
The new technology also uses a special ink containing silver flakes, which can be formed and conductive at room temperature. Traditional 3D printing inks usually require high temperatures to handle, which can cause burns to the human body. In addition, removing the electronic device printed on the skin is also very simple, just peel off with tweezers or rinse with water.
In addition to printing electronic products, the new 3D printing technology also has huge application potential in other fields. The research team led by McCalpin and the University of Minnesota School of Medicine collaborated to successfully use bio-ink to print cells on mouse skin wounds, which is expected to provide new methods for wound healing and skin disease treatment.

A room divider is a screen or piece of furniture placed in a way that divides a room into separate areas.
Room dividers are used by interior designers and architects as means to divide space into separate distinct areas.
A room divider for a conference hall.
There are a number of different types of room dividers such as cubicle partitions, pipe and drape screens, shoji screens, and walls. Room dividers can be made from many materials, including wood, fabric, plexiglass, framed cotton canvas, pleated fabric or mirrors. Plants, shelves or railings might also be used as dividers. Portable room dividers have folded wall panels supported on wheels.
Types
In general, room dividers are used in one of these ways:
To divide rooms, creating a more efficient use of the space within the room.
As decorators and/or accent pieces to add character to room space.
To hide areas of different usage or privacy protection
To decorate rooms for better home design effect
Room dividers differ in nature being either:
Permanent as in using wine shelves in restaurants
Built in as in sliding partitions in offices
Portable or temporary as for example in convention centers
Fixed room dividers and hanging room dividers
They may completely obscure as in floor to ceiling dividers, or may allow sight through as for example when plant pots are used to divide areas.
