Production of ceramic rods using a 3D printer

In February 2019, in the foundry of the enterprise, work continues on testing the manufacture of ceramic rods forming the inner cavity of the turbine blade airfoils on the 3D printer. The equipment installed in the mechanical-foundry-thermal complex allows making complex ceramic products with the parameters of the shape and surface roughness specified by the design documentation. However, the application of this technology is constrained by the low technological strength of products in thin sections.
There are reviewed the proposals on finalizing the printing technology and the subsequent processing of the rods, including with specialists in the field of ceramic materials from the Institute of Materials Science named after I.M. Frantsevich in Kiev
