From aerospace and defence to digital dentistry and medical devices, 3D printed parts are used in a variety of industries. Currently, 3D printed parts are very fragile and only used in the prototyping phase of materials or as a toy for display.
A doctoral student in the department of materials science and engineering at Texas A&M University has pioneered a countermeasure to transform the landscape of 3D printing today.
Brandon Sweeney and his advisor Dr Micah Green discovered a way to make 3D printed parts stronger and immediately useful in real-world applications. Sweeney and Green applied the traditional welding concepts to bond the submillimeter layers in a 3D printed part together, while in a microwave.
The team recently published their work in the journal Science Advances.
“I was able to see the amazing potential of the technology, such as the way it sped up our manufacturing times and enabled our CAD designs to come to life in a matter of hours,” Sweeney said. “Unfortunately, we always knew those parts were not really strong enough to survive in a real-world application.”
