Title:
COATED FILAMENT FOR IMPROVED ADDITIVE MANUFACTURING PARTS
Document Type and Number:
Japanese Patent JP2021109442
Kind Code:
A
Abstract:
To provide a coated filament that prevents formation of voids between adjacent beads in filament based additive manufacturing such as fused filament fabrication.SOLUTION: A coated filament 10 for use in additive manufacturing includes a base polymer layer 8 formed of a base polymer material 2, and a coating polymer layer 9 formed of a coating polymer material 7. At least the coating material 7 is susceptible to dielectric heating in response to electromagnetic radiation, thereby promoting fusion between adjacent beads of the coated filament that are deposited during the additive manufacturing process. Specifically, when electromagnetic radiation is applied to an interface area between two adjacent beads of the coated filament, the polymer coating layer 9 melts to diffuse across the interface area, thereby preventing formation of voids.SELECTED DRAWING: Figure 1
