My last three extrusion articles in PlasticsToday dealt with inpush, getting the material into the extruder (see links at the end of this article). Now I'll focus on outpush, or output as it's more ...

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 ...

Earlier this year, Pacific Northwest National Laboratory in Richland, Washington, announced that it took delivery of the second generation of its ShAPE, or Shear Assisted Processing and Extrusion, ...

Extrusion is a process used for creating a product (an extrudate) by forcing a material through a die or an orifice to form a shape, or alternatively an extruder is used to produce semi-finished or ...
