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 ...

In past columns, I've written about measurement of the key process variables in extrusion: Melt temperature, melt pressure and motor load . . . the vital signs. However, I shouldn't assume that all of ...

We have a fascination with gloss. Think of shining shoes, polishing apples for the teacher, don’t touch my car, squeaky-clean and more. Somehow, shiny noses are the other way around, which is why we ...

Extrusion is a process widely used in the polymer processing industry. It involves pushing material through a die with a specific cross-sectional shape, resulting in products like profiles, thin ...

The hot melt extrusion (HME) process can be employed in the production of a wide range of pharmaceutical dosage forms, including capsules, tablets, lozenges and implants. HME is suitable for both ...

Liposomes have emerged as a significant biomedical carrier system. Particle size is one of the most important elements impacting the performance of liposomes. High-pressure homogenization, extrusion, ...

Viscometers are used by the food industry to ensure the consistency and quality of liquid foods. Zwick Roell claims its new tester provides what the company claims is an economical alternative to ...

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 ...
