Extrusion characteristics of reinforced composite materials
Soviet Powder Metallurgy and Metal Ceramics, 1986The constituents of a metal-metal fiber material react with each other in accordance with the relevant constitution diagram. The results of experiments conducted on metal specimens have enabled a process to be developed for the production of fiber materials by extrusion and for structural investigations to commence.

Extrusion of implanted materials
1985Generally, extrusion is interpreted as a reaction of the body to non- tolerated implants. This applies to many uses of various materials in different surgical fields. Middle ear implants are used for very different purposes (e.g. ossicular replacement prostheses, grommets, sheat- ings, posterior canal wall implants, materials for obliteration).

Preliminary investigation into metal-material extrusion
Progress in Additive Manufacturing, 2020Additive manufacturing (AM) technologies provide a method of fabrication that minimizes the production of waste and maximizes part customization. The most common form of this technology is material extrusion (ME) in which material is deposited layer-by-layer to produce a highly customized part.

Material Extrusion Based Ceramic Additive Manufacturing
2020Abstract This article is a review of the material extrusion-based ceramic additive manufacturing (MECAM) processes. The discussion begins with details of extrusion with filament and paste, covering the most popular variants of paste extrusion-based MECAM techniques that can be differentiated based on paste type and the method of shape ...

Extrusion freeforming of Nylon 6 materials
Polymer, 1999A modified Nylon 6 formulation, developed originally for reaction injection moulding, has been used to freeform small parts. Liquid monomer is deposited as a fine stream from computer-controlled writing head and polymerizes on a heated plate as the part is built up.

Extrusion and Co-extrusion: A Technology in Probiotic Encapsulation with Alternative Materials
Current Pharmaceutical Biotechnology: Encapsulation, in particular extrusion and co-extrusion, is a common practice to protect probiotics from the harsh conditions of the digestive tract as well as processing. Hydrocolloids, including proteins and carbohydrates, natural or modified, are a group of ingredients used as the wall material in extrusion.

Non-isothermal Extrusion of Composite Materials
International Polymer Processing, 1990Abstract Non-isothermal extrusion, of non-dilute fiber suspensions with solidification is analyzed by means of an integral constitutive equation for melt fiber suspension and a novel, streamlined inverse finite element method (IIFEM), to account for the solidification.

Interference fit of material extrusion parts
Additive Manufacturing, 2019Abstract Material extrusion is an Additive Manufacturing process able to fabricate a physical object directly from a virtual model using layer by layer deposition of a thermoplastic filament extruded by a nozzle. The fabrication of functional components implies the need for the assembly with other parts with different properties in terms of material ...
