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 ...

Producing balloons used for angioplasty catheters calls for tubing that has more stringent requirements than that used for other uses, such as catheter body or strain relief. To ensure that the proper ...

Editor?s note: Chris Rauwendaal is a designer, consultant, and seminar instructor who has written extensively on process engineering and extrusion topics. Part 1 of this article (PM&A Nov./Dec. 2002) ...

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 ...

When it comes to 3D printing clay, there are a lot of challenges to be met. An extruder capable of pushing clay is critical, and [davidsfeir] has an updated version suitable for an Ender 3 printer.

Polymers are defined as materials consisting of macromolecules that are made up of small, regularly repeating smaller subunits. The coextrusion process is a manufacturing process that uses different ...

Discover how the Thermo Scientific TM Process TM 11 and Process TM 16 extruders can aid in mechanical polymer recycling by helping define the optimal workflow and recycling parameters. Why is it ...

In contrast to the success of their molten-plastic cousins, paste extrusion 3D printers have never really attained much popularity. This is shame because, as the [Hand and Machine] research group at ...

All architecture is grounded in the earth. This pliant, resilient raw material is the origin of extruded ceramic tiles—clay transformed from its natural state into an architectural solution without ...
