Definitions
- the invention relates to a method and a device for producing a three-dimensional object according to the preamble of claim 1 and claim 10.
- Such a method or device is known from EP-A-0 171 069.
- the carrier is lowered in a bath of liquid, polymerizable plastic, so that a layer of liquid plastic can form, and this layer is then polymerized or solidified at the corresponding points on the object by irradiation with a laser beam. Since the polymerization requires a certain reaction time, the laser beam cannot be guided over the layer as quickly as desired, so that the production time cannot be shortened as desired.
- the object of the invention is to reduce the time required for producing the object.
- a container 1 which is open on its upper side is filled up to a level or a surface 2 with a light-curable, liquid plastic material 3.
- a support 4 in the area of the plastic 3 with an essentially flat and horizontal support plate 5, which is arranged parallel to the surface 2 and by means of a schematically indicated height adjustment device 6 in the direction perpendicular to the surface 2 or to Carrier plate 5 can be moved and positioned.
- the height adjustment device is connected to a controller 7 for controlling the displacement position.
- the object 8 which is constructed from a plurality of layers 8a, 8b, 8c and 8d in the manner described later, is located on the carrier plate.
- An irradiation device 9 for solidifying the uppermost layer 8d adjoining the surface 2 contains an illumination device 10 with a radiation source 11, which generates a focused beam 13 via optics 12.
- the radiation source 11 is preferably a light source such as e.g. a laser, but can also be any other source of electromagnetic radiation.
- a plurality of, for example three, in each case partially radiation-permeable mirrors 14, 15, 16 are arranged one behind the other in the direction of the beam 13, each of which is gimbally suspended independently of one another and corresponds to this ⁇ corresponding schematically indicated control devices 17, 18, 19 can be pivoted such that the beam 13 incident on the mirrors 14, 15, 16 is independent of the mirrors 14, 15, 16 as a reflected beam 20, 21, 22 within certain areas of the surface 2 can be positioned.
- two rotating mirrors, one for each coordinate direction can be used in a known manner.
- control devices 17, 18, 19 are each connected to the controller 7 for controlling the direction of the beams 20, 21, 22.
- the data about the shape of the object 8, which was created on the basis of a construction program or the like, are first stored in the controller 7. These data are prepared for the production of the object 8 in such a way that the object is broken down into a plurality of horizontal layers which are thin in comparison to the object dimension and the shape data are available for each layer.
- the controller 7 controls the height adjustment device 6 such that the surface of the carrier plate 5 is positioned below the surface 2 at a predetermined height corresponding to the thickness of the layer 8a.
- the controller 7 controls the height adjustment device 6 such that the surface of the carrier plate 5 is positioned below the surface 2 at a predetermined height corresponding to the thickness of the layer 8a.
- the control device 7 controls the lighting device 9 and in particular the control devices 17, 18, 19 in such a way that the beam 20, 21, 22 reflected by each corresponding mirror 14, 15, 16 strikes predetermined areas of the layer 8a and thus solidified these areas.
- an edge region of the layer 8a can be solidified by a first beam 21 deflected by the central mirror 15 and the central region of the layer 8a by the two other beams 20, 22.
- the edge region is solidified in a closed train, which enables an improved, in particular smoother surface of the object without offset.
- the inner region can then be solidified by the other steels 20, 22 in such a way that these beams alternately sweep along adjacent linear regions or each beam 20, 22 solidifies a separate area or a separate field of the layer. In the latter
- the height adjustment device 6 is lowered by the controller 7 by the amount of the intended thickness of the second layer 8b, so that a liquid layer with the thickness of the second layer 8b forms on the first layer 8a. Thereafter, the control devices 17, 18, 19 are controlled analogously to the first layer to solidify the second layer. The following layers 8c, 8d are produced accordingly.
- a plurality of radiation sources 11 can also be used be provided in each case an associated mirror or a deflection device for the light beam.
- a particularly advantageous modification of the described device also consists in that a radiation source and 5 mirrors are provided, four mirrors being arranged in a ring around a fifth, central mirror.
- Each mirror is provided with a corresponding control or deflection device for the respective light beam and is controlled by the controller 7 to solidify individual areas of the layers 8a ... 8d. It is particularly advantageous if the central mirror is controlled in such a way that it takes over the consolidation of the edge region of the layer in accordance with the mirror 15.
- the division of the beam 13 and the separate deflection of the partial beams can also be achieved by a plurality of light guides, in one end of which the beam 13 enters and the other end by means of a known x, y shifting device in accordance with Rays 20,21,22 is guided over the surface.
- Further possible modifications consist in the fact that plastic, metal or plastic-coated metal or ceramic powders are also used instead of the liquid plastic. All suitable methods such as scattering and spraying devices, wipers, rollers etc. can be used to apply a layer of this material. Depending on its properties, the material can also be solidified by other forms of electromagnetic radiation, such as an electron beam or thermal radiation.
