Researchers at Oak Ridge National Laboratory (ORNL) in Tennessee have introduced a novel vacuum-assisted extrusion method that significantly reduces internal porosity in large-scale 3D-printed polymer ...

Scientists have developed a vacuum-assisted extrusion method that reduces internal porosity -- by up to 75% -- in large-scale 3D-printed polymer parts. Large-scale additive manufacturing has been ...

A new publication from Opto-Electronic Advances; DOI 10.29026/oea.2022.210058 discusses formation, evaluation, and influence of porosity in metals additively manufactured by laser powder bed fusion.

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 ...

South Korean researchers have developed a process to produce ultra-thin wafers without sacrificing any of the substrates. Their technique is based on a new approach involving the use of ...

A new process that solves the porosity problem may be a boon for superlight suspension arms, turbo impellers, and other automotive components. The aluminum blocks and heads for this Indy car engine ...

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 ...

(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 ...
