Novel vacuum-assisted extrusion technique improves performance of polymer prints

New vacuum-assisted extrusion technique improves performance of polymer prints

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 hindered by internal porosity that weaken printed components. Reducing porosity is key to improving overall performance. Researchers tackled this challenge with a novel approach: integrating a vacuum hopper during the extrusion process to remove trapped…
