Description
- The invention is related to a device and a method for a layer-wise manufacturing of a three-dimensional object from a building material in powder form. In particular, the invention is related to a method for selective laser sintering, in the following briefly called laser sintering method, and to a laser sintering device.
- A laser sintering method and a laser sintering device according to the preamble of
claims - In the known method for each building process a specified amount of old powder, i.e. powder, which remains from one or several previous building processes, is used. However, the old powder is subject to an aging process.
- For example the old powder is thermally and/or thermooxidatively damaged and thus has other material properties and for this reason also other processing parameters than new powder. Therefore, it can be added to the new powder only in defined proportions in order not to put at risk the building process and the part quality. The so-called refresh rate is the value of the percentage of new powder in the mixed amount/percentage of old powder in the mixed amount (e.g. 50/50) that is used for a building process. This refresh rate shall be as small as possible, because then the costs for new powder can be saved.
- In DE 101 05 504 A1 it is proposed to preprocess the old powder or a mixture of old powder and new powder before the solidification, for example by fluidizing, in order to reduce the effect of aging-related quality-reducing changes such that more old powder can be added.
- By such a pre-treatment, however, usually not all aging-related quality-reducing changes of the powder can be eliminated. In particular, a too high proportion of old powder gives rise to an unsatisfactory surface quality of the outer walls of the part due to dip positions, which are also called “sink marks” or “orange peel”.
- From WO 2005/097475 a laser sintering method and a laser sintering powder for such a method are known, wherein it is attempted to solve the problem of the dip positions by using a certain material that has an increased stability in the laser sintering process and thus has fewer aging-related damages, when it is used as old powder. However, in that case the user is dependent on the use of this specific powder which in turn has different properties than the familiar powder used up to that time and possibly does not meet all demands.
- Furthermore, from U.S. Pat. No. 4,938,816 it is known to compact the powder in laser sintering by generating an electromagnetic field during or before the solidification with the laser.
- From
EP 1 058 675 B1 it is known to compact an applied powder layer by means of a roller in the layer sintering of a ceramics powder. Thereby the time shall be reduced, which is required in the sintering in the solid phase of the ceramics powder. - From DE 195 14 740 C1 a device for laser sintering, in particular of metal powder, is known, in which the powder is applied by means of an application blade. The blade has at the application edge a beveled edge having an angle between 30° and 90°. A beveled face, which has an angle between 1° and 60° is also provided at the opposing smoothing edge. The smoothing edge smoothes an already solidified layer.
- It is an object of the invention to provide a method and a device for producing a three-dimensional object, in particular a laser sintering method and a laser sintering device, by which the refresh rate can be reduced and by which the costs of the process can be reduced.
- The object is achieved by a device according to
claim 1 and a method according toclaims 7, 8 or 13. Further developments of the invention are described in the dependent claims. - The method has the advantage that conventional powder for laser sintering such as polyamide or other families, in particular polyaryletheretherketone (PEEK), in each case with and without additions such as glass particles, reinforcing fibers, metallic additions as e.g. aluminum-filled polyamide and others, can be used, the properties of which are sufficiently known. Furthermore, by the method and the device the refresh rate can be reduced up to 0% new powder (0/100).
- Further features and utilities of the invention arise from the description of embodiments based on the figures, of which:
-
FIG. 1 shows a schematic representation of a laser sintering device; and -
FIG. 2 shows a schematic perspective side view of the powder application by means of an application device in the laser sintering device; -
FIG. 3 shows a schematic representation of the cross-section of the application blade of the application device; and -
FIG. 4 shows a schematic partial cross-sectional perspective view of how the application device applies powder onto an already sintered layer. - The laser sintering device shown in
FIG. 1 comprises acontainer 1, which is open to the top and has therein a support 2 that can be moved in a vertical direction, supports theobject 3 to be formed and defines a building field. The support 2 is adjusted in the vertical direction such that the respective layer of the object, which layer is to be solidified, lies in a work plane 4. Further, anapplication device 5 for applying the building material in powder form, which is to be solidified by means of electromagnetic radiation, is provided. The device comprises also alaser 6. Thelaser beam 7 that has been generated by thelaser 6 is directed onto acoupling window 9 by means of a deflection device 8, which lets thelaser beam 7 pass into theprocess chamber 10 and focuses it to a predetermined point in the work plane 4. - Furthermore, a
control unit 11 is provided through which the components of the device are controlled in a coordinated manner in order to perform the building process. - As is shown in
FIG. 2 , the application device comprises twojaws powder supply 20 is located between these twojaws jaws blades FIG. 2 the present direction of movement of theapplication device 5, which is shown, is indicated by B. - As can be seen in
FIG. 3 , the blade has a thickness D in the direction of movement B and has twosurfaces surface 60 c, wherein the blade is positioned in the application device such that the slopingsurface 60 c ascends in the direction of application B. The sloping surface forms an application surface. Together with a surface E that is in parallel to the work plane 4 and the support surface, respectively, it includes an acute angle α, which lies between a value larger than 0° and approximately 5°, preferably at approximately 2°. Thelower edge 60 d between theperpendicular surface 60 b and the slopingblade surface 60 c is at a height x with respect to the plane E. When the blade has a thickness D of approximately 6 mm, the height x is larger than 0.03 and smaller than approximately 0.5 mm. The thickness of the blade can be between 1 mm and 20 mm. Thereby the application device has only a small angle of incidence of thesurface 60 c in the application direction B. - The
second application blade 61 is arranged at the inner side of thesecond jaw 52 and is formed such that it is mirror-symmetrical to thefirst application blade 60. Thus, thebeveled surface 61 c of thesecond application blade 61 has an angle of incidence opposite to the application direction B, in which thefirst application blade 60 performs the application operation. Thereby it is possible to apply a new powder layer by means of the application device during the forward movement and the backward movement, respectively, and to respectively take along the powder supply and if necessary supplement it. - In operation preferably a plastic powder, for example a polymer powder such as polyamide, in particular polyamide 12, or a powder from another family such as PEEK, in each case with or without additions, is used as powder. Before the application operation old powder, which remains as not sintered powder from one or several previous building processes, is mixed with new powder. For example, for unfilled polyamide the refresh rate is 50%-30% of new powder (refresh rate 50/50 to 30/70) and for filled polyamide the refresh rate is 100%-70% of new powder (refresh rate (100/0 to 70/30). The term “new powder” describes a powder that has not been used in any previous manufacturing step. The term “old powder” describes a powder consisting of approximately 90% powder, which is co-inserted into the powder cake and is stored under a high temperature for the whole duration of the building process, and approximately 10% powder, which has been shifted into overflow containers during the layer application.
- The mixing can take place outside or inside the laser sintering device. Before each application operation the powder is added in the
application device 5 in an amount that is sufficient for applying a layer of the powder. - Then the
application device 5 moves across the building field, wherein theapplication blade 60 applies alayer 21 having the predetermined thickness d. As thesurface 60 c is sloped with respect to the direction of application B, a force acts onto the powder to be spread, which powder is positioned in the powder column located in front of theapplication blade 60, wherein the force is directed into the work plane. Thereby thepowder 20 is compressed during the application of the layer. - Then the cross-section of the
object 3 in the respective laser is irradiated with the laser beam and thus the powder is solidified. Afterwards theapplication device 5 is again filled with powder and is moved in a direction opposite to the direction B shown inFIGS. 2 and 3 . Thereby the second application blade 62, which is formed mirror-symmetrically to thefirst application blade 60, acts as application device and applies a new powder layer onto the last solidified layer and the powder surrounding the solidified region, respectively. -
FIG. 4 explains schematically the operation of the blade according to the invention. Theobject 3 comprises a plurality of already solidifiedlayers 21 and not sinteredpowder 22 surrounding these layers. The last applied and solidified layer comprises an already solidified portion 23 a and not sintered powder 23 b. As the density increases during the solidification, the already solidified region 23 a is slightly lowered with respect to the level of the unsolidified powder 23 b. Thereby edges 24 are formed between the already solidified portion 23 a and the unsolidified region 23 b. - When the
blade 60 according to the invention is used, it was observed with surprise that a compression pressure acts on the particles in the layer and there are marginal or no dip positions in the completed part. - By increasing the powder bed density it is not only possible to reduce the refresh rate, but also to use a powder, which up to now is not or only to a limited extent suited for the laser sintering process.
- The powder bed density is measured as follows: A closed hollow thin-walled block-shaped laser sintering part is exposed such that the enclosed volume during the exposure has a value 100 mm×10 mm×15 mm in the directions xyz. The volume surrounding the part has to be dimensioned correspondingly. Adhering powder remnants are removed from the outside of the thus manufactured part and the thus manufactured part is weighed. Thereafter the part is cut open and the powder inside is drained and the empty part is again weighed. The difference between the masses corresponds to the mass of the enclosed powder volume. As the powder volume is known, the density of the powder bed can be calculated from it.
- The following table shows a result of the device according to the invention and of the method compared to the prior art. Polyamide 12, which can be obtained under the trade name PA 2200 (sintering powder of the applicant for the EOSINT P machine) was used as laser sintering powder. The applied layer thickness was 0.15 mm:

- By the method and the device, respectively, the required proportion of new powder can be reduced. In an exceptional case it is even possible to work with nearly 100% of old powder. Furthermore, the table shows that the solution viscosity, which is a measure for the melt viscosity of the material, increases with the proportion of old powder. Therefore, by the method according to the invention it is also possible to sinter also powder materials that have a correspondingly high melt viscosity and could not be processed by the methods and devices existing hitherto. Polyamide (PA), in particular PA 12, is advantageously suited for the device and the method, because it can be manufactured by a precipitation process and therefore has a particularly smooth surface compared to a milled powder. Therefore, settling processes can advantageously take place during the application.
- The geometry of the application device is not limited to the specifically shown embodiment. For instance, the
surfaces - The ascending slope of the application surface need not be constant, but may also ascend in a different way, e.g. may be scaled or may have a different shape.
- Instead of a laser also a different energy source, which is suited for the solidification of a material in power form such as an electron beam source can be used. Also other ways of an energy entry are possible such as mask sintering, inhibition sintering or a line-shaped energy entry or an energy entry via an array.
