Silicon carbide has been the most widely used material for the use of structural ceramics. Characteristics such as relatively low thermal expansion, high force-to-weight radius, high thermal conductivity, hardness, resistance to abrasion and corrosion, and most importantly, the maintenance of elastic resistance at temperatures up to 1650 ° C, have led to a wide range of uses.

• Silicon carbide materials are very difficult to process by any AM technology and nearly all current appliions are based on reaction bonded silicon carbide (RBSiC). Those—like binder jetting and bound powder extrusion—that do not require light or direct heat as an energy source during the printing process are better suited as SiC is a heat resistant, dark material that does not
