A coupled extrusion and in-situ UV curing method enables high-precision polymer-derived ceramic 3D printing with fewer ...

Researchers propose a novel process paradigm of photopolymerization-extrusion coupled molding targeting the 3D printing of ...

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 ...

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 ...

Extrusion using a gear pump is useful in production processes where temperatures must remain low, for example in the automotive industry to produce car tires. At too high temperatures, material ...

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 ...

It all began with a show-stopping demonstration that wowed audiences in the manufacturing world. It was at the International Manufacturing Technology Show in 2014 when the three-dimensional printing ...

While countless tubes are extruded or injection molded each year, these manufacturing techniques are neither the most optimal nor the most cost-effective methods available to medical device ...

For its latest project FAE SRL, a specialist in electrical panel design for OEMs in the plastics sector, needed a drive solution that could meet the rigorous demands of continuous operation, high ...

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 ...
