3 - D - printed device builds better nanofibers:
Printed nozzle system could make uniform, versatile fibers at much lower cost.
The 3 - D -
printed nozzle is also 25 percent lighter than its predecessor, which means lower fuel costs for airlines.
But conventional techniques for printing circuits don't work well with silver nanowires; the nanowires often clog
the printing nozzles.
They concluded that the mechanical strength used to push the ink through
the printing nozzle was sufficient to align it.
The researchers said that emerging materials may allow 3 - D printers to work faster, thus making it more difficult for smartphone sensors to determine
the print nozzle's movement.
These sensors can infer the location of
the print nozzle as it moves to create the three - dimensional object being printed.
The INKJET process uses no electrodes, and the voltage is applied only to the piezoelectric
printing nozzle.

GE acquired 3D -
printing specialists Morris Technologies in 2012, and uses 3D
printing to make fuel
nozzles for its new LEAP jet engine.
Notably, GE's new jet engine uses a series of sophisticated 3 - D -
printed fuel
nozzles; they are lighter and far more durable because intricate cooling channels have been built into them.
Using the idea of the inkjet printer, in which small
nozzles shoot ink at the required area, the idea of inkjet -
printed biological cells was considered.
An exciting recent development is the High Laydown Technology, a novel way of firing the
nozzles during the inkjet
printing process.
«Our approach uses electrohydrodynamic
printing, which relies on electrostatic force to eject the ink from the
nozzle and draw it to the appropriate site on the substrate,» says Jingyan Dong, co-corresponding author of a paper on the work and an associate professor in NC State's Edward P. Fitts Department of Industrial & Systems Engineering.
You need [the ink] to flow out of a
nozzle like toothpaste, and it can maintain its shape after it's
printed.»
«This hydrogel has ideal flow characteristics for
printing through a
nozzle,» Zhao says.
For example, a system could have many
nozzles like a showerhead, allowing it to
print on large areas.
The importance of the technology is already being seen at a number of large companies such as GE who have made enormous strides in industrial 3D
printing by opening a facility to produce the 3D
printed fuel
nozzles for its advanced LEAP jet engines, and Rolls - Royce announcing they will flight - test what it claims to be the largest 3D
printed aerospace component to ever power an aircraft.
«Bob Marley» taught me that when you have two
nozzles and one jams, you should be able to switch it out with a second
nozzle to keep
printing.
It took me three months to figure out a
nozzle problem — I could
print items, but he would jam and smoke all the time.
It will use
nozzles to deposit tiny liquid droplets of semiconductor polymer materials on a plastic substrate to form circuits in much the same way that inkjets
print type on paper.
As it moves, tiny
nozzles spray droplets of ink, forming
printed words and pictures.
It also applies firmware upgrades on it own, and automatic maintenance features like
print bed detection and automatic
nozzle cleaning.
