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 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 ...

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 ...

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, ...

Researchers at Lawrence Livermore National Laboratory (LLNL) have modernized high-explosive (HE) manufacturing by adapting ...

For decades, manufacturing plastic-bonded high explosives, or PBXs, has relied on legacy processes like slurry coating. In ...

Choosing appropriate screens for an extrusion process involves striking a balance between filtration needs (removing more contaminants) and overheating. Finer screens get more contaminants out, but ...

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 ...

Additive free, multimaterial 3D printing is achieved for milk-based products without temperature control. Researchers from the Singapore University of Technology and Design (SUTD) developed a method ...

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 ...
