Application of 3D-printing extrusion technology in foundry production

A brief review of the additive technologies used for producing the foundry forming tooling is carried out. The peculiarities of using extrusion 3D-ptinting technology for producing the foundry forming tooling in comparison with other additive technologies are considered. The possibilities to produce the foundry forming tooling from clay viscous-flowing materials using extrusion 3D-ptinting technology are demonstrated experimentally.
