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 ...

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 ...

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 ...

The global plastics industry is at a critical juncture, with mounting pressure to reduce waste and embrace sustainable practices. At the heart of this transformation lies extrusion technology — a ...

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 ...

Bosch has published three related German patent applications that point toward a rather interesting 3D printing concept: a ...

There are essentially three widely used technologies for manufacturing plastic products: Injection molding, extrusion, and blow molding. Injection molding is the most commonly used process for the ...

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 ...
