METHOD FOR DEPOSITING MOLTEN METAL FILAMENT USING A LASER BEAM SWEPT ACROSS THE SURFACE OF THE WORKPIECE - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240375218 titled 'METHOD FOR DEPOSITING MOLTEN METAL FILAMENT USING A LASER BEAM SWEPT ACROSS THE SURFACE OF THE WORKPIECE

The abstract describes an additive manufacturing method that involves using a laser to focus on the outlet of a supply head delivering a metallic wire onto a workpiece. The equipment item moves the zone of interaction of the laser beam with the wire along a main path representing the workpiece's geometry. The movement is modulated in a longitudinal and transverse direction in the focal plane, creating a curve swept at a speed greater than the travel speed along the main path. The 2-axis modulation is controlled by a system entering parameters for each manufacture.

• Laser-focused additive manufacturing method

Original Abstract Submitted

an additive manufacturing method involves commanding movement across the surface of a workpiece of an equipment item comprising a laser, of which the beam is focused on the outlet of a supply head that delivers a metallic wire. the equipment item is caused to move the zone of interaction of the laser beam with the wire along a main path representative of the geometry of the workpiece being manufactured. the movement of the zone of interaction is modulated by 2-axis modulation in a longitudinal direction parallel to the main path and a transverse direction normal to the main path in the focal plane. the deviation defines a curve swept at a speed greater than a speed of travel along the main path. the 2-axis modulation is controlled by a control system comprising means for entering the parameters, for each manufacture, of the control law used for the 2-axis modulation.
