Method for preparing three-dimensional green body
The invention relates to a method for producing a three-dimensional green body (GB) by means of a three-dimensional (3D) printing method, wherein at least one raw material, a building chamber and a three-dimensional extrusion printer (3D) printer comprising at least one nozzle are used. In the method, the at least one raw material is fed into a 3D printer comprising the at least one nozzle, where the at least one raw material comprises at least one binder (B) and at least one inorganic powder (IP), and where the at least one binder (B) comprises at least one polyoxymethylene (POM). The at least one feedstock is then heated in a 3D printer and extruded through the at least one nozzle to obtain at least one extruded wire. A three-dimensional green body (GB) is formed layer by layer from the at least one extruded wire on a substrate (BP) located in a build chamber, where the substrate (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 substrate (BP) are removed from the building chamber, wherein the three-dimensional green body (GB) is attached to the substrate (BP). The invention further relates to a three-dimensional green body (GB) produced by this method and to a three-dimensional sintered body produced from this three-dimensional green body (GB).
本发明涉及一种通过三维(3D)打印方法制备三维生坯(GB)的方法，其中使用至少一种原料、构建室和包含至少一个喷嘴的三维挤出打印机(3D)打印机。在该方法中，将所述至少一种原料供入包含所述至少一个喷嘴的3D打印机中，其中所述至少一种原料包含至少一种粘合剂(B)和至少一种无机粉末(IP)，并且其中所述至少一种粘合剂(B)包含至少一种聚甲醛(POM)。然后将所述至少一种原料在3D打印机中加热并通过所述至少一个喷嘴挤出以获得至少一根挤出线材。由所述至少一根挤出线材，在位于构建室中的基板(BP)上逐层形成三维生坯(GB)，其中基板(BP)包含所述至少一种粘合剂(B)和任选的所述至少一种无机粉末(IP)。将三维生坯(GB)和基板(BP)从构建室中取出，其中三维生坯(GB)附接到基板(BP)。本发明进一步涉及通过该方法制备的三维生坯(GB)以及由该三维生坯(GB)制备的三维烧结体。
