A PROCESS FOR THE PRODUCTION OF A THREE-DIMENSIONAL GREEN BODY
The present invention relates to a process for the production of a three-dimensional green body (GB) by a three-dimensional (3D) printing process, in which at least one feedstock, a built chamber and a three-dimensional extrusion printer (3D printer) containing at least one nozzle are employed. In this process, the at least one feedstock is fed into the 3D printer containing the at least one nozzle, wherein the at least one feedstock comprises at least one binder (B) and at least one inorganic powder (IP), and wherein the at least one binder (B) comprises at least one polyoxymethylene (POM). The at least one feedstock is then heated inside the 3D printer and extruded through the at least one nozzle in order to obtain at least one extruded strand. From the at least one extruded strand, the three-dimensional green body (GB) is formed layer by layer on a base plate (BP) located in the build chamber, wherein the base plate (BP) comprises the at least one binder (B) and optionally the at least one inorganic powder (IP). The three-dimensional green body (GB) and the base plate (BP) are removed from the build chamber, wherein the three-dimensional green body (GB) is attached to the base plate (BP). The present invention further relates to a three-dimensional green body (GB) prepared by this process and to a three-dimensional sintered body prepared from the three-dimensional green body (GB).
