MACHINE TOOL SYSTEM AND METHOD FOR ADDITIVE MANUFACTURING

A machine for additive manufacturing positions a film having additive material relative to a substrate. The additive material is melted onto the substrate or previously formed layers of a workpiece using a laser. The substrate/workpiece and/or the film can be positioned in multiple axes so that comp...

Zusammenfassung:	A machine for additive manufacturing positions a film having additive material relative to a substrate. The additive material is melted onto the substrate or previously formed layers of a workpiece using a laser. The substrate/workpiece and/or the film can be positioned in multiple axes so that complex shapes can be formed without extraneous supporting structures. The film-based delivery of the additive material allows deposition in orientations other than horizontal as is required for powder-only additive manufacturing and also avoids the inconvenience of collecting and recycling unused loose powdered metal.
