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 have resolved a long-standing debate surrounding laser additive manufacturing processes with a pioneering approach to defect detection. Researchers from EPFL have resolved a long-standing ...

(Nanowerk News) Structural defects that form during additive manufacturing, also known as 3D printing, are a barrier to some applications of this technology. Researchers used diagnostic tools and ...

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 ...

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 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 ...

Researchers working at the nanoscale have found that 3D-printed metal parts can stay mechanically strong even when they ...

Additive manufacturing, also known as 3D printing, has had a major impact on the contemporary design and production process. First developed in 1988 with the aim of allowing for rapid prototyping, ...

(Nanowerk News) 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 ...
