Description

TECHNICAL FIELD [0001] The present invention relates to a three-dimensional printer for a metal alloy filament,

The present invention relates to a three-dimensional printer for a metal alloy filament in which a metal alloy filament is heated, melted, extruded and laminated to produce a three-dimensional laminate of a metal alloy.

In a conventional three-dimensional printer, a thermoplastic plastic filament is melted and extruded and laminated to form a filament. The filament forcibly fed from the feed motor is extruded into a liquid state through a nozzle heated at a melting temperature (200-300 degrees) It is adapted to complete the sculpture.

However, such conventional three-dimensional printers have a disadvantage that they are vulnerable to low strength and heat because they form a three-dimensional structure by laminating plastics.
