摘要： The invention refers to a method and an apparatus for producing three-dimensional objects by using a converting machine, which is controlled by computer instructions. The material consists of a number of sheet- or disc-shaped sections (16). On the flat side of each section (16) at least one electrode (17a, 17b; 42, 43) is placed, and an electric voltage is impressed thereon sufficient to cause a breakover between the electrodes. Parts or particles of material located opposed to the electrodes are thus removed from or connected with the respective section (16). The treated sections are integrated layer by layer in a programmed sequence forming said three-dimensional object.

摘要： Device for cutting of materials by means of at least one cutting means, which partly is provided to be controlled by preferably a plotter or the like, partly to be heated to a temperature, which is higher than the melting temperature of the material by electric induction and/or resistance heating, and partly comprises a cutting part (30) and a holder part (31) connected thereto. The cutting part (30) is constituted by a cutting electrode formed as a substantially cylindrical pin with considerably smaller cross sectional area than the holder part (31), so that the cutting part emits substantially the whole amount of heat generated by current supplied, and that the electrode (30) is connected into a control circuit for controlling the temperature of the electrode in dependence on its cutting speed.

摘要： Device for manufacturing of three-dimensional objects, of a substantially homogeneous material by means of a converting machine (1), which is controllable by means of computer instructions. The material, which is constituted by web, sheet or disc shaped sections (16), is insertable in said converting machine, where every separate section is provided to be subjected to a material cutting treatment in accordance to given computer instructions. The separate converted sections are arranged to be brought together and integrated with each other in a programmed sequence. The converting machine (1) comprises at least one means (57) for annihilation or connection of material particles in the material section (16) in the form of at least one electrode of a spark converting machine, glow pen, plasma cutter or the like, which means and/or which section is controllable by means of computer instructions in the x- and/or y-direction of the section plane.
