杰森玛耶兹1994Method to create three-dimensional bodies (30), for example models, formers, finished products, mi-finished products, among others, from a medium (12) consisting of particles, by producing a number of cross-ctional layers (25), each and every one reprenting a cross ction of an object that has to be manufactured, whereby by means of an energy producing device (22a), which moves over the medium, the particles, in the just then topmost layer, in chon areas, are connected at least with each other or with each other and with a preceding layer, in accordance with signals from a control unit (20). Particles that are no connected in respective layers are removed. The energy producing device (22a), which compris at least one electrode (22b), forms one of the poles in a circuit, where the other pole is constituted of said medium (12), which is electrically conducting or miconducting when the poles are connected to at least a voltage source (40), whereby energy waves are formed between said electrode and said medium (12), for example in form of at least an electric arc or heat, that connect the material particles of said medium by changing the physical characteristics of said particles in said
