Video: 3D-printing Technique Uses Ultrasonic Waves to Print Composite Materials – IHS Electronics360

A new 3D-printing technique may enable folks to turn it into most additional products at home, inexpensively.
A team of engineers at the University of Bristol has created the technique that uses ultrasonic waves to create a pattern of microscopic glass fibers that donate components increased durablity. A laser and so cures the epoxy resin and turn it intos the component can print composite materials, that are utilized in most products like tennis rackets, golf clubs and actually airplanes.

In its demonstrations, the team carefully positioned millions of small reinforcement fibers that were molded into a microscopic reinforcement framework to donate the materials their durablity. The microstructures were and so set in place with a focutilized laser beam, that cured the epoxy resin and and so printed the object.
“We have demonstrated that our ultrasonic process can be introduced cheaply to an off-the-shelf 3D printing device, that and so turns it into a composite printing device,” says Tom Llewellyn-Jones, a PhD student in high end composites who created the process.
In the study, a print speed of 20mm/s was achieved, that is much like to conventional additive layer techniques.
The new approach shows how harsh architectures can be printed inside a 3D object. Since the technique is versatile, its can enable 3D printing of most particle materials, shapes, and sizes.
“Our work has shown the initially example of 3D printing with real-time control over the distribution of an internal microstructure and it demonstrates the future to create rapid prototypes with harsh microstructural arrangements. This orientation control donates us the skill to create printed parts with tailored material properties, all without compromising the printing,” says Bruce Drinkwater, Professor of Ultrasonics in the Department of Mechanical Engineering.
