WebFeb 9, 2024 · Fused Filament Fabrication (FFF) 3D printing is an additive technology used to manufacture parts. Used in the engineering industry for prototyping polymetric parts, this disruptive technology has been adopted commercially and there are affordable printers on the market that allow for at-home printing. This paper examines six methods of reducing … WebA fuse acts as a circuit breaker to protect against overload by interrupting the power flow. Typically, the fuse element is a thin wire with a low melting point. Higher power through the fuse means more increased current flow through it, which heats the wire and causes it to melt or blow. This interrupts the power flow.
