Description

Technical Field

[0001] The utility model relates to the technical field of laser printing, in particular to a working platform structure for laser printing. Background Art

[0002] Laser cladding and laser 3D printing are both types of additive manufacturing technologies. Laser cladding uses the laser and alloy powder to act synchronously on the metal surface (substrate) to form a metallurgical bonding layer, thereby achieving the effect of repairing the surface size of the workpiece (substrate) and strengthening and extending its life. Laser 3D printing directly melts a single substance or alloy powder.
