Title: Coated sheets for improved additive manufacturing parts
Inventor: NISHANT K SINHA
IPC: B33Y70/00
Filed: 2021-01-05
Abstract: To provide a coated sheet that prevents formation of voids between sheets in sheet-based additive manufacturing such as LOM.SOLUTION: A coated sheet for use in additive manufacturing includes a base polymer layer formed of a base polymer material, and a coating polymer layer 20 formed of a coating polymer material. At least the coating polymer material is susceptible to dielectric heating in response to electromagnetic radiation, thereby promoting fusion between adjacent coated sheets during the additive manufacturing process. Specifically, when electromagnetic radiation is applied to at least an interface area 68 between adjacent coated sheets, the polymer coating layer of each coated sheet melts to diffuse across an interface area, thereby preventing formation of voids. The base polymer material and the coating polymer material may have similar melting points and compatible solubility parameters to further promote fusion between sheets.SELECTED DRAWING: Figure 2
