Why do fiber filament weld beads break easily
The low toughness of fiber–bead interface promotes the emergence of break inside bead, and high fiber strength is capable of activating break outside bead. It usually means your voltage is too low for your wire speed, or your shielding gas coverage is poor. Layer adhesion refers to the strength of the bond between individual layers of filament in a 3D print. Ideally, each new layer should melt into and fuse with the previous one, creating a homogenous, strong object. The solution involves optimizing mold design to relocate the weld line, adjusting processing parameters to improve fiber entanglement, and selecting materials that promote better bonding across the knit line.
