There are other differences. While traditional 3D printers build parts from computer files, the cold-spray machine uses digital scans of actual jet engine parts to accurately reconstruct the broken part.
GE has the ability to print parts as large as 1 meter in diameter directly from a computer file.
The process looks something like a hi-tech sewing machine weaving an emblem onto a garment.
But soon the pattern begins to rise and swell, and a nose, constructed using a bio-ink containing real human cells, grows upwards from the glass, glowing brightly under an ultraviolet light.
The researchers’ new approach involves printing circuits made of electrically conductive metallic inks and insulating polymeric inks. These can be produced in a single inkjet printing process, using an ultraviolet light to solidify the inks.
n research described in the journal Nature Photonics, the Turkey-based researchers have developed a 3D laser fabrication technique that deliberately creates the conditions for exploiting these interactions, known as nonlinear feedback mechanisms.
