Additive Manufacturing of Ceramics: Issues, Potentialities, and Opportunities

Abstract

Additive manufacturing (AM) is a technology which has the potential not only to change the way of conventional industrial manufacturing processes, adding material instead of subtracting, but also to create entirely new production and business strategies. Since about three decades, AM technologies have been used to fabricate prototypes or models mostly from polymeric or metallic materials. Recently, products have been introduced into the market that cannot be produced in another way than additively. Ceramic materials are, however, not easy to process by AM technologies, as their processing requirements (in terms of feedstock and/or sintering) are very challenging. On the other hand, it can be expected that AM technologies, once successful, will have an extraordinary impact on the industrial production of ceramic components and, moreover, will open for ceramics new uses and new markets.

Fracture Toughness (KIC) of Lithography Based Manufactured Alumina Ceramic

“…Another problem is that components with complicated geometries are not possible to be manufactured with conventional methods [1] Components usually are designed by computer aided design (CAD) and it is expected also that ceramic components can be manufactured directly from CAD information. Additive Manufacturing (AM) is a new method that makes it possible to manufacture parts with a complex geometry [2][3][4][5][6][7] without subsequent machining. Additive manufacturing is a process during which the three dimensional (3D) object is produced by sequential assembly of layers.…”

Prototipos cerámicos – diseño, computación y fabricación digital

“…Research by the contour crafting group switched to concrete soon after the initial study in clay, with the focus being on-site use of additive manufacturing in order to simplify construction logistics. Other work in 3D printing of technical and clay-based ceramics has focused on producing smaller objects (12). Commercial services are available to print small ceramic pieces by selectively solidifying a fine granular ceramic powder using commercially available 3D printer.…”

Reforming and Desulphurization of Syngas by 3D-printed Catalyst Carriers

“…For components with complicated shapes, or which must be produced in small quantities 3DP ALM technology is a good choice. In general, the best ALM technology for porous structures is the Fused Direct Method (FDM), which uses ceramic-based feedstocks [8]. FDM has been demonstrated to have low cost, better interconnectivity (i.e.…”
