Definitions
- the invention relates to a method for producing a three-dimensional object according to the preamble of claim 1.
- a method for producing a three-dimensional object is known under the term "stereolithography".
- a layer of a liquid or powdery material is applied to a support or an already solidified layer and is solidified at the corresponding points by irradiation with a directed light beam, for example a laser beam.
- the object is produced in layers by successive solidification of a plurality of successive layers.
- a method for producing a three-dimensional object is known from DE 43 09 524, in which the entire object or each layer of the object to be formed is broken down into an inner core region and an outer envelope region and the radiation effect in the core region and in the envelope region Generation of different properties of both areas is controlled differently.
- the object to be formed is broken down into an envelope area and a core area in a computer.
- the object data corresponding to the decomposition of the object to be formed into the envelope area and core area are made available to a further computer which controls an irradiation device for consolidating the layers of the object to be formed.
- WO 94/07 681 a method for producing a three-dimensional object by successively solidifying layers of the object lying one above the other is known, in which partial areas of a layer are initially solidified and thereby connected to underlying partial areas of the previously solidified layer to form multilayer cells , and then adjacent sub-areas of the same layer are connected to one another by solidifying narrow connecting areas. This is intended to reduce deformation of the object.
- the three-dimensional disassembly of the support structure into the core area and the envelope area makes the support structure very homogeneous, since there is no double irradiation or double exposure within the support structure.
- the envelope area can be constructed in such a way that an easily detachable connection to the object is produced, and the core area can be constructed in such a way that a sufficiently stable support structure with a short construction time - 3a -
- Fig. 1 is a schematic representation of an apparatus for performing the method according to the invention
- FIG. 2 is a schematic cross-sectional view of a
- Fig. 3 shows a section along the line A - A of
- FIG. 4 shows a schematic cross-sectional view of an object to be formed with a support structure according to a further embodiment of the invention.
- a device for carrying out the method according to the invention has a container 1 which is open on its upper side and which has a material which can be solidified under the influence of electromagnetic radiation to a level or a surface 2 3 is filled.
- a carrier 4 with an essentially flat and horizontal carrier plate 5, which is arranged parallel to the surface 2 and can be moved and positioned up and down perpendicularly to the surface 2 or to the carrier plate 5 by means of a height adjustment device, not shown can.
- An object 6 to be formed is arranged on the carrier plate 5 together with a support structure 20, the object 6 and the support structure 20 each consisting of a plurality of layers 6a, 6b, 6c, 6d and 6e or 20a, 20b and 20c, which each extend parallel to the surface 2 and to the support plate 5, are constructed.
- a device (not shown) for smoothing the surface 2 of the solidifiable material 3 is arranged above the container 1.
- an irradiation device 7 for example a laser, which emits a directed light beam 8.
- the directed light beam 8 - 5 - is via a deflection device 9, for example a
- a controller 11 controls the deflecting device 9 in such a way that the deflected beam 10 strikes any desired location on the surface 2 of the solidifiable material 3 in the container 1.
- the controller 11 is connected to a computer unit 50 which the. Control 11 supplies the corresponding data for solidifying the layers of the object 6 and the support structure 20.
- the carrier plate 5 is positioned in the container 1 in a first step in such a way that between the top of the carrier plate 5 and the surface 2 of the solidifiable material 3 in the container 1, a layer thickness corresponding exactly to the intended one There is a distance.
- the layer of the solidifiable material 3 located above the carrier plate 5 is determined by means of the light beam 8, 10 generated by the irradiation device 7 and controlled by the deflection device 9 and the control device 11 at predetermined, corresponding to the object 6 and the associated support structure 20 Places irradiated, whereby the material 3 is solidified and thus forms a solid layer 6a or 20a corresponding to the shape of an object and the support structure.
- the object and the support construction data for the control of the consolidation of each layer are calculated by breaking down a three-dimensional model of the object 6 and the support structure 20 into individual layers.
- the entire three-dimensional support structure 20 in the computer unit 50 is broken down into an envelope area and a core area.
- the envelope - 6 - area and the core area form two independent parts or individual objects of the support structure.
- the three-dimensional model of the support structure can also be broken down in a separate computer, and the data generated can be transferred to the computer unit 50.
- the radiation effect during solidification in each layer is now carried out in different ways, depending on whether it is the core area or the envelope area of the support structure. Due to the disassembly, a double exposure of overlapping parts of the support structure no longer occurs.
- FIG. 2 shows a section through a support structure 21 together with the object 6 in the region of the connection of the support structure 21 to the object 6.
- the support structure 21 is broken down into a core region 22 and an envelope region 23, which have different structures and thus different properties exhibit.
- the radiation effect is preferably carried out in such a way that the deformation of the support structure 21 when the object 6 is generated is minimal.
- the core area 22 must be exposed hard and thus inelastically, i. H. strong solidification must be created.
- the core area 22 of the support structure 21 is only solidified in individual, spaced-apart partial areas which are either not connected at all or are connected to one another by connecting webs. If the envelope region 23 is sufficiently stable, it is also possible not to consolidate the core region 22 at all. After completion, non-consolidated material can be discharged through openings provided in the envelope area and / or in the core area.
- the solidification of the support structure 21 in the envelope area 23 can preferably be used to produce a sufficiently stable but easily detachable connection of the support structure to the
- the exposure in the envelope area is soft, i. H. less solidification than in the core area is generated, so that the envelope area of the support structure does not inseparably adhere to the object in the area of the connection to the object.
- Individual spaced subregions can also be solidified in the envelope region 23 of the support structure, which are either not connected at all or are connected to one another by connecting webs.
- the distance between the partial areas in the envelope area is preferably smaller than the distance between the partial areas in the core area so that the object is adequately supported.
- areas of the envelope area 23 of the support structure 21, which adjoin the object it is possible to solidify only individual contiguous blocks or blocks of the envelope area, thereby producing a perforated connection to the object, which detaches the support structure after Completion of the object facilitated.
- the wall thickness of the envelope area can be adjusted within the entire support structure and / or from layer to layer. The distance between the support structure and the walls of the object to be formed can thus be set.
- a further embodiment of the method according to the invention consists in disassembling a support structure 30 into shell regions 31, 32, 33 and a core region 26 forming several shells, these regions 31, 32, 33, 26 are each separate parts or individual objects of the support structure.
- Different shell thicknesses are possible.
- An envelope area can, for example, completely or Include only partially.
- the shell 31 has no Z thickness, but it has an XY wall thickness.
- the envelope region 32 has only a Z thickness, while the envelope region 33 has a uniform wall thickness in the XY and Z directions.
- the core 26 can be built with very large spaced sections. With such a shell-shaped disassembly, it is possible to optimally direct the flow of force through the support structure with minimal construction time.
