Additive manufacturing and 3D printing methods based on the extrusion of material have become very popular in recent years. There are many ceramics, but direct method gives largest range sizes printed objects enables scaling processes also large-scale applications. Additionally, application this to ceramic materials is particular importance due its low cost, ease use, high utilization. The pape...

In this paper, several versions of extrusion processes were used to provide severe plastic deformation for grain refinement (with a modified ECAE extrusion) and for grain/fiber alignment (with straight extrusion). The process was performed at elevated temperatures to reduce extrusion pressure, and in order to increase strength and avoid grain growth secondary phases were added or insitu formed....

Compared to single-unit dosage forms, oral multiparticulate drug-delivery systems (e.g. pellets, granules) offer biopharmaceutical advantages in terms of a more even and predictable distribution and transportation in the gastrointestinal tract. There are different pelletization and granulation techniques available to prepare drug loaded spherical particles or granules. Extrusion Spheronization ...

An extrusion process especially designed for extrusion of pipes made from fiber reinforced cementitious materials has been developed at Department of Structural Engineering and Materials at the Technical University of Denmark. Engineered Cementitious Composite (ECC) materials have been developed in recent years at Department of Civil and Envirionmental Engineering, University of Michigan. These...

Malnutrition is one of the foremost causes of death among children below 5 years in developing countries. Development of nutrient-dense food formulations using locally available crops has been proposed as a means to combat this menace. This study optimized the extrusion process for the production of a nutritious amaranth-based porridge flour. Least cost formulations containing grain amaranth, g...
