Fundamentals and applications of 3D printing for novel materials

Development of the Fray-Farthing-Chen Cambridge Process: Towards the Sustainable Production of Titanium and Its Alloys

“…One of the key areas of recent development within the titanium industry is powder metallurgy (e.g., 3D printing 25,26 and near-net-shape manufacturing 31 ). Since titanium and its alloys produced from the FFC-Cambridge process are typically in a porous structure (see Fig.…”

“…8 Due to the relatively low density of titanium, some alloying elements tend to segregate and multi-step remelting is necessary to achieve full homogenisation of the final alloys at high costs. Furthermore, the fabrication of titanium alloys in complex shapes increases both the waste and cost and calls for creative manufacturing techniques such as additive manufacturing, [24][25][26] nearnet-shape casting, 27 spark plasma sintering (SPS), 28 and metal injection moulding. 29 Most of these advanced techniques are based on powder metallurgy, 30,31 and powder production requires sophisticated pulverisation and spheroidisation processes, which in turn adds extra costs to the final products.…”

Polymer/Carbon Nanotubes (CNT) Nanocomposites Processing Using Additive Manufacturing (Three-Dimensional Printing) Technique: An Overview

“…There are numerous compatible materials available for 3DP, for example, metals, polymers, and ceramics [14][15][16]. Among these materials, polymers are in demand because of their diversified types, availability, processability, unique properties and price.…”

Laboratory 3D printing system

“…Various 3D printing technologies has become an indispensable field in various fields from engineering and aviation to printing live fabrics. [1] One of the significant limitations of expanding research in the field of 3D printing is the extremely high cost of installations, ranging from thousands to hundreds of thousands of dollars. Also commercial 3D printers quite space consuming, not much of them designed as on-the-table device.…”
