METHOD FOR LAYER-WISE ADDITIVE MANUFACTURING OF A SHAPED BODY
The present invention is directed to a Method for layer-wise additive manufacturing of a shaped body made up of slices of processed layers, said method comprising the steps:creating a layer of a slurry, said slurry including binder, a dispersing medium and a particulate filler material,solidifying the slurry layer,directing electromagnetic radiation to the solidified layer for processing it by debinding and/or sintering, andrepeating the above-mentioned steps to successively build the shaped body,characterized in that said creating a slurry layer is performed by a laser induced forward transfer (LIFT) process utilizing a laser to direct laser beam pulses to act on a coating of slurry on a carrier to transfer droplets of slurry to a receptor surface to create the slurry layer which is then processed further by above-mentioned steps of solidifying, and debinding and/or sintering.
