Extensive research on nature-inspired cellular metamaterials has globally inspired
innovations using single material and limited multifunctionality. Additive manufacturing (AM) …

Rheology has a key position in polymer research, being an important link in the so-called
'chain of knowledge'reaching from the production of polymers to their end-use properties. A …

Multi-material extrusion in 3D printing is gaining attention due to a wide range of possibilities
that it provides, specially driven by the commercial availability of a large variety of non …

Fused-filament fabrication (FFF) is an extrusion-based form of three-dimensional (3D)
printing for manufacturing parts rapidly. Commercially available polypropylene (PP) …

Rheology is the science of deformation and flow of materials [1]. The Society of Rheology's
Greek motto" Panta Rei" translates as" All things flow." Actually, all materials do flow, given …

Most materials conventionally found in nature expand with an increase in temperature. In
actual systems and assemblies like precision instruments, this can cause thermal distortions …

This chapter is devoted to the presentation of the fundamental rheological properties of
polymers and their processing technologies. Measurements of the rheological properties …

In this work, a polyamide hot melt adhesive was evaluated as a feedstock for material
extrusion additive manufacturing (AM). This adhesive, Technomelt PA 6910, is a …

The continually growing plastics market consists of more than 250 million tons of product
annually, making the recurring problem of polymer melt fracture an acute issue in the …

In this work, two different HDPEs with virtually identical number, Mn, and weight, Mw,
average molecular weights were investigated from rheological as well as die drool …
