Scientists at Oak Ridge National Laboratory have developed a vacuum-assisted extrusion method that reduces internal porosity—by up to 75%—in large-scale 3D-printed polymer parts. The paper is ...

Reactive processing in polymer extrusion harnesses the extruder as a continuous reactor, enabling in situ chemical modification of polymers while they are conveyed and melted. By integrating ...

Extrusion is a continuous processing technique in which polymeric materials are conveyed, melted and homogenised as they are forced through a die to form strands, sheets or complex profiles. Key to ...

Changes such as the transition from crystalline to amorphous phases or shifts in vibrational modes can be used to customize the end-polymer's mechanical, thermal, and optical properties to specific ...

Polyfuze Graphics has introduced a technology that “fuses” permanent labels into the plastic during the extrusion process, eliminating the risk of peeling or detachment. The innovation offers ...

Real-time visibility into polymer melt viscosity during the extrusion process results in improved quality of the end product and minimizes material waste. However, existing monitoring technologies ...

Angel investors understand the high stakes of funding new technologies. The journey is fraught with financial, technical and market risks—but when a groundbreaking well-designed innovation meets the ...

For a long time, factory managers and procurement teams treated recycled resin like a bad compromise. The mindset was simple: ...

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 ...

On the right, a vacuum-assisted extrusion is leveraged in large-scale additive manufacturing to reduce porosity in printed parts. The inset image, on the left, is a close-up of the vacuum-assisted ...
