Additive manufacturing method using focused light heating source

A method of manufacturing a metallic component by additive manufacturing, the method comprising:

• providing a work surface on which the component is to be manufactured,
• providing at least one deposition material being at least one wire from which the component is to be composed,
• advancing the at least one deposition material to a localized deposition area where the at least one deposition material is added to the component being manufactured,
• focusing light emitted from at least one light source in the localized deposition area so that the at least one deposition material is deposited for building up the component, wherein the at least one light source is one or more high power electrical lamps or one or more Light Emitting Diodes (LEDs), wherein the at least one focused light has a focused spot size of between 0.5 to 4 mm in the localized deposition area, and
• mutually moving the work surface and/or the focused light and the at least one deposition material in a way that results in the additive manufacturing of the component,
• the method being characterized in that the at least one light source emits incoherent light, and in that at least one light focusing mirror and/or lens is used to focus the incoherent light in the localized deposition area,
• wherein the at least one wire comprises a material selected from the group consisting of pure aluminium, alloyed aluminium, magnesium, titanium, beryllium, steel, nickel, cobalt, copper, solder, brazing alloys and alloys of these materials.
