Research reveals how pores form during metals additive manufacturing and become defects trapped in solidifying metal. The practical value of this research is that it can inform industry on how to ...

Researchers can now detect the formation of keyhole pores, one of the most challenging defects common in additive manufacturing, with incredible accuracy. A research team led by Tao Sun, associate ...

Metal additive manufacturing (AM), widely recognised for its ability to produce lightweight and geometrically complex components, has long faced a major barrier to wider adoption: microscopic internal ...

Longitudinal (top) and axial (middle) images of X-Ray CT data of parts with 6 internal defects: a spherical clog, a stellated shaped clog, a cone shaped void, a blob shaped void, an elliptical warp of ...

A real-time correction system and open-access data release aim to reduce failed builds and material waste in metal additive manufacturing.

A growing number of academic and industrial research groups regard the integration of artificial intelligence-based algorithms into the 3D printing process as a promising approach to improve the ...

Understanding how dislocations (line defects in the crystal structure) occur when 3D-printing metals has been unclear to materials scientists. Understanding when and how dislocations form in ...

A recent study published in the journal Advanced Materials introduces triply-twinned metamaterials, a new architectural strategy for strengthening lightweight lattice structures produced through ...

Additive manufacturing (or 3D printing) performs well in prototyping, where speed and flexibility outweigh cost and throughput constraints. Problems begin when those same designs move into production.

Researchers at the University of Birmingham have developed a 3D printing method capable of producing geometrically complex ...

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 ...
