Scientists use temperature data to tune -- and fix -- defects in 3D-printed metallic parts. With its ability to yield parts with complex shapes and minimal waste, additive manufacturing has the ...

Figure 1. Ultrasonic testing using pulse echo and through-transmission methods. Pulse echo (left and center) uses a transducer that sends and receives ultrasound energy, producing both A- and B-scan ...

Optical 3D metrology enables fast, non-contact surface roughness measurement of defects and roughness for precise ...

Scientists of the Far Eastern Federal University (FEFU) have used a unique mathematical model to calculate the data of 3D images of defects in the volume of transparent functional materials. The ...

Laser powder bed fusion is a dominant additive manufacturing technology that has yet to reach its potential. The problem facing industry is that tiny bubbles or pores sometimes form during the ...

Researchers have been searching for various ways to control defects in the 3D printing process that can create parts and objects that are functionally compromised. The U.S. Department of Energy’s (DOE ...

A research team led by Tao Sun, associate professor of materials science and engineering at the University of Virginia, has made new discoveries that can expand additive manufacturing in aerospace and ...

(Nanowerk News) Metal-organic framework (MOF) nanocrystals are hybrid materials, built from metal clusters and organic linkers with an almost unlimited number of possible combinations. Their ...

Small defects in 3D printed metal parts limit their performance and are roadblocks preventing the technology from being more widely used. Researchers at Argonne National Laboratory theorized that the ...
