- a sliced file is generated to get a full representation of three-dimensional model consisting of the superposition of successive cross-sections.
- all layers are considered separately and even if several consecutive layers are similar, their coding size remains approximately the same leading to a huge file which may be a problem.
- An object of the present invention is to provide a slicing method which is suitable for continuous additive manufacturing of three-dimensional parts.
- a method for forming at least one three-dimensional article through successive fusion of parts of a powder bed comprising the steps of: providing at least one model of the three-dimensional article, wherein the model of the three-dimensional article is described in a 2-dimensional angular coordinate system; applying a powder layer on a support structure; directing at least one energy beam from at least one energy beam source, the energy beam source being an electromagnetic energy beam source and/or a charged particle beam source, over the powder layer causing the powder layer to fuse in first selected locations according to the model to form a first portion of the three-dimensional article, providing a first portion of the powder layer simultaneous as fusing a second portion of the powder layer, wherein the second portion of the powder layer is fused along a line perpendicular to a rotational axis of the support structure.

- a rotational axis of the model is coinciding with the rotational axis of the three-dimensional article built on the support structure.
- the powder layer is provided continuously on the support structure during the formation of the three-dimensional article.

- (x,y,z) are the Cartesian coordinates
- r is a radial coordinate (distance to Z axis)
- ⁇ is an angular coordinate [rad].

- a continuous cutting model (continuous slicing) of the article to build is generated and stored in the control unit 10 .
- the vacuum chamber 320 is capable of maintaining a vacuum environment by means of or via a vacuum system, which system may comprise a turbo molecular pump, a scroll pump, an ion pump and one or more valves which are well known to a skilled person in the art and therefore need no further explanation in this context.
- the vacuum system may be controlled by the control unit 10 .
- the work plate may be provided in an enclosable chamber provided with ambient air and atmosphere pressure.

- the axis of rotation 15 may be vertical and the work plate 5 may be annular. This rotation can be done intermittently or continuously together with the work plate 5 lowering continuously as the build progress.
- the build envelope in the case of an energy beam non-aligned with the rotational axis 15 , the build envelope can be much wider than the beam scan area in a powder bed plan. It is obvious that the work plate 5 lowering range remain identical to standard equipment. It is entirely conceivable that the build envelope in vertical direction will be designed to extend the maximum build height up to approximately 1000 mm.
- a three-dimensional object 11 in a rotational movement around an axis 15 , is melted between its inner and outer boundary radii in the beam scanning area 9 .
- the beam movement is coordinated with the rotational movement by the control unit 10 .
- the melting strategy allow changing the revolution speed during the revolution of the work plate 5 and the melting is preferably located along the main radius between sector I and II.
- we get three concurrent spots 1, 2, 3 to produce several melted lines 16 In this example, three lines along radii R 1 . . . R 3 ).
- the duration of each spot and frequency on each line is the same, at a given time of the building.

- the rotation speed may be calculated from the combination of eq. (1) and (2), at a given radius, in the middle for instance.
- the linear speed difference of powder particles between the outer and inner radius can be accommodated by a change in beam power giving a homogeneous melting all along a radial line.
- sector I may be the preferred working area when multiplexing the beam on a radial line and other sectors II-IV are used to make easier any change in rotation speed.
- This arrangement eliminates the need of a XY-beam trajectory software and allow the machine to operate continuously in a 1-dimensional radial beam movement directly linked to the powder bed rotation speed.
- the process may be particularly suitable to be applied to produce principally large parts, although not exclusively, turbine cases or large aerospace structural frames with a central hole.

Description
- This application claims priority to and the benefit of U.S. Provisional Patent Application Ser. No. 62/091,990, filed Dec. 15, 2014, and U.S. Provisional Patent Application Ser. No. 62/235,934, filed Oct. 1, 2015; the contents of both of which as are hereby incorporated by reference in their entirety.
- 1. Technical Field
- The present invention relates to an improved method for manufacturing a 3-dimensional object.
- 2. Related Art
- Freeform fabrication or additive manufacturing is a method for forming three-dimensional articles through successive fusion of chosen parts of powder layers applied to a work plate. A method and apparatus according to this technique is disclosed in US 2009/0152771.
- Such an apparatus may comprise a
work plate 5 on which the three-dimensional article is to be formed, a powder dispenser, arranged to lay down a thin layer of powder on thework plate 5 for the formation of a powder bed, a ray gun for delivering energy to the powder whereby fusion of the powder takes place, elements for control of the ray given off by the ray gun over the powder bed for the formation of a cross section of the three-dimensional article through fusion of parts of the powder bed, and a controlling computer, in which information is stored concerning consecutive cross sections of the three-dimensional article. A three-dimensional article is formed through consecutive fusions of consecutively formed cross sections of powder layers, successively laid down by the powder dispenser. - Sliced files are widely used for additive manufacturing applications and can be generated using digital data, such as any suitable solid computer aided design (“CAD”) model. The sliced layers consist of successive cross-sections taken at ascending Z-intervals where each slice is taken parallel to the XY-plane as shown in
FIG. 3 , with Z along a vertical direction. Usually, a sliced file is generated to get a full representation of three-dimensional model consisting of the superposition of successive cross-sections. According to this usual slicing algorithm, all layers are considered separately and even if several consecutive layers are similar, their coding size remains approximately the same leading to a huge file which may be a problem. - There is a demand for additive manufacturing techniques which is capable of building three-dimensional articles faster and faster. This may ultimately require an additive manufacturing method in which the current slicing method is more or less unsuitable.

Indeed, embodiments of the invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will satisfy applicable legal requirements. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly known and understood by one of ordinary skill in the art to which the invention relates. The term “or” is used herein in both the alternative and conjunctive sense, unless otherwise indicated. Like numbers refer to like elements throughout.
- To facilitate the understanding of this invention, a number of terms are defined below. Terms defined herein have meanings as commonly understood by a person of ordinary skill in the areas relevant to the present invention. Terms such as “a”, “an” and “the” are not intended to refer to only a singular entity, but include the general class of which a specific example may be used for illustration. The terminology herein is used to describe specific embodiments of the invention, but their usage does not delimit the invention, except as outlined in the claims.
- The term “three-dimensional structures” and the like as used herein refer generally to intended or actually fabricated three-dimensional configurations (e.g. of structural material or materials) that are intended to be used for a particular purpose. Such structures, etc. may, for example, be designed with the aid of a three-dimensional CAD system.
- The term “electron beam” as used herein in various embodiments refers to any charged particle beam. The sources of a charged particle beam can include an electron gun, a linear accelerator and so on.
- The invention relates to a method for producing three-dimensional objects by powder additive manufacturing, for example by selective laser melting (SLM), selective laser sintering (SLS) or Electron Beam Melting (EBM). In various example embodiments the object may be wider than the beam scanning area.
- An
energy beam source 1 may be used so that abeam 2 defines a 2D pattern in a thin bed ofmetal powder material 3 leveled byrake 6. The rake may be movable or stationary. Apowder bed 4 may in an example embodiment measure a diameter 750 mm in a plan view and awork plate 5 can be lowered 200-500 mm by amechanism elevator 8. Thus parts up to 0 750×500 mm can be manufactured in such equipment. It should be understood that these are not fundamental limits however. - Sliced files are widely used for additive manufacturing applications and can be generated using digital data, such as any suitable solid computer aided design (“CAD”) model. The sliced layers may consist of successive cross sections taken at ascending Z-intervals, where each slice is taken parallel to the XY plane as shown on
FIG. 3 , with Z along a vertical direction. - To allow additive manufacturing to be conducted in a continuous way, a continuous computer description of a 3D object may be used. Such continuous description may eliminate one dimension, thus allowing to associate an angular position to the object's boundaries along a radial line.
- A possible application of this invention may consist in adjusting dynamically the position of a printer head—or a beam spot—along a radial line to melt the 3D object between the 1D segments described in this mathematical representation. With an appropriate system coordinate change, each interior and exterior boundary polyline from the solid material can advantageously be described in the two dimensional coordinate system (r,α) as follow:
-
- where (x,y,z) are the Cartesian coordinates, r is a radial coordinate (distance to Z axis) and α is an angular coordinate [rad]. α is positive if measured counter clockwise as seen from any point with positive height. H is the height of the three-dimensional article which is to be built.
- According to the method proposed by the present invention, a mathematical model may be generated from a helical like cutting of a three-dimensional article to be formed as shown in
FIG. 4 . This slicing method require to define a rotation axis along for instance Z (longitudinal) and an origin angular position. - A file containing all r coordinates (intersecting the line that rotates uniformly around the axis) can be generated for each angular coordinate a with a step size chose in accordance to the accuracy needed. For instance, a three-dimensional article resulting from the Boolean union between: i) a cylindrical tube with the height of 100 mm and of
internal radius 300 mm and external radius 301 mm; with, ii) a conical frustum with theheight 100 mm and upper internal andexternal radii 300 mm and 301 mm respectively and bottom internal and external radii 319 mm and 320 mm respectively; with, iii) a triangular flange with theheight 100 mm and base 20 mm and a thickness of 1 mm placed between i) and ii); may be described, according to the inventive method, by a continuous helical cutting as shown onFIG. 5A andFIG. 5B . - The digital representation of the 3D object may result in better accuracy if the slice thickness is chosen accordingly to the minimal details accuracy.
- In the previously mentioned example, the result of the coarse helical-like slicing along the Z-axis parallel to length L, with a slice thickness t=20 mm is defined in this system coordinate as presented as a graph in the
FIG. 5 . In this simple test-case a full description of the 3D object is obtained in 5 laps (part height divided by t). - The full representation of such a three-dimensional model would correspond to a very minimal coding size, in the previously mentioned example the digital data to store to construct the closed segment lines consist in 32 points only being in the two dimensional coordinate system (r,z):
- Boundary loop (1)=300,0;300,100;301,100;320,0;319,0;317.1,10;301.1,10;301,0;300,0;
Boundary loop (2)=301,11;301,30;313.3,30;316.9,11;301,11;
Boundary loop (3)=301,31;301,50;309.5,50;313.1,31;301,31;
Boundary loop (4)=301,51;301,70;305.7,70;309.3,51;301,51;
Boundary loop (5)=301,71;301,90;301.9,90;305.5,71;301,71;
Boundary loop (6)=301,91;301,94.7;301.7,91 -
FIG. 1 discloses only one beam source for sake of simplicity. Of course, any number of beam sources may be used. - In the embodiment of this invention illustrated in
FIG. 1 , thework plate 5 can be moved in aprocess chamber 14 across a beam scan area 9 such that: - a) a continuous cutting model (continuous slicing) of the article to build is generated and stored in the
control unit 10. - b) an optional preheating a
work plate 5 to an adequate start temperature. Energy deposition on thework plate 5 during preheating may be done either during an incremental or continuous movement of thework plate 5. - c) depositing with a moving feeding member of a quantity of powder in the melting chamber to form a layer of powders with a regular and substantially uniform thickness. This may be done, but not limited to, by a fixed powder layering device while the
work plate 5 is moving. - d) an optional preheating the layer of powder to a temperature below the melting point of the powders. The energy may be transmitted to the powders either during an incremental or
continuous work plate 5 movement. As a function of the temperature loss during one rotation, it is possible to arrange areheat area 12 before the powder come again to the beam scan area. - e) performing the melting by scanning with a focused beam in the area corresponding to a portion of the continuous cutting of the article according to the model stored in the
control unit 10. - Repeating the steps b) to e) occurs either as the
work plate 5 rotates continuously either incrementally with a “quadrant” rotation until reaching the top definition of the article. Thework plate 5 is lowered as the build progress, each revolution a distance ranging 20 to 200 μm equal to the thickness of the completed layer. - The
vacuum chamber 320 is capable of maintaining a vacuum environment by means of or via a vacuum system, which system may comprise a turbo molecular pump, a scroll pump, an ion pump and one or more valves which are well known to a skilled person in the art and therefore need no further explanation in this context. The vacuum system may be controlled by thecontrol unit 10. In another embodiment the work plate may be provided in an enclosable chamber provided with ambient air and atmosphere pressure. In still another example embodiment the work plate may be provided in open air. - This invention concerns the provision of a rotation axis to the
work plate 5 aligned or non-aligned with the center line of the energy beam. In an example embodiment of the present invention the axis ofrotation 15 may be vertical and thework plate 5 may be annular. This rotation can be done intermittently or continuously together with thework plate 5 lowering continuously as the build progress. - By this mean, in the case of an energy beam non-aligned with the
rotational axis 15, the build envelope can be much wider than the beam scan area in a powder bed plan. It is obvious that thework plate 5 lowering range remain identical to standard equipment. It is entirely conceivable that the build envelope in vertical direction will be designed to extend the maximum build height up to approximately 1000 mm. - As illustrated in
FIG. 2 , a three-dimensional object 11, in a rotational movement around anaxis 15, is melted between its inner and outer boundary radii in the beam scanning area 9. The beam movement is coordinated with the rotational movement by thecontrol unit 10. In this embodiment the melting strategy allow changing the revolution speed during the revolution of thework plate 5 and the melting is preferably located along the main radius between sector I and II. In this example, by use of a beam multiplexing, we get threeconcurrent spots - At a given radius Ri, the relation between the angular speed w and linear speed of the rotating powder bed is the following:
-
LineSpeed=Ri*w (1) -
And we also have: -
LineSpeed=SpotOffset*Fb/NbOfSpots (2) -
With: -
NbOfSpots=(Rout−Rin)/Line offset (3) - where,—Spot Offset: distance between two successive melting spots on the same radius—Line Offset: distance between two adjacent lines—Line speed: speed of a powder particle—Fb: Beam pulse frequency
- Thus, if we use a fixed value of Line Offset for an entire build cycle, the number of spots required to melt effectively the part geometry can change periodically according to eq. (3). Then taken into account a limit value for Spot Offset, the rotation speed may be calculated from the combination of eq. (1) and (2), at a given radius, in the middle for instance. Lastly, the linear speed difference of powder particles between the outer and inner radius can be accommodated by a change in beam power giving a homogeneous melting all along a radial line.
- In
FIG. 2 , sector I may be the preferred working area when multiplexing the beam on a radial line and other sectors II-IV are used to make easier any change in rotation speed. This arrangement eliminates the need of a XY-beam trajectory software and allow the machine to operate continuously in a 1-dimensional radial beam movement directly linked to the powder bed rotation speed. - The process may be particularly suitable to be applied to produce principally large parts, although not exclusively, turbine cases or large aerospace structural frames with a central hole. The present invention may be used for manufacturing one continuous object wider than the beam scanning area, it must be understood that the principles of the present invention can be applied equally to the production of several objects included into the build envelope.
- It must be understood that the present invention is potentially applicable to any type of layer wise rapid prototyping and additive manufacturing machines, and to other machines using the layer-on-layer fabrication technique, including non-metallic material.
- The energy beam source may be an
electron beam source 1 generating an electron beam, which may be used for melting or fusing togetherpowder material 3 provided on thework plate 5. Thecontrol unit 10 may be used for controlling and managing theelectron beam 2 emitted from theelectron beam source 1. Theelectron beam 2 may be deflected between at least a first extreme position and at least a second extreme position. - At least one focusing coil (not shown), at least one deflection coil (not shown) and an electron beam power supply (not shown) may be electrically connected to the
control unit 10. A beam deflection unit (not shown) may comprise the at least one focusing coil, the at least one deflection coil and optionally at least one astigmatism coil. In an example embodiment of the invention theelectron beam source 1 may generate a focusable electron beam with an accelerating voltage of about 60 kV and with a beam power in the range of 0-3 kW. The pressure in the vacuum chamber may be in the range of 1×10−3-1×10−6 mBar when building the three-dimensional article by fusing the powder layer by layer with theenergy beam source 1. - Instead of melting the powder material with one electron beam, one or more laser beams and/or electron beams may be used. Each laser beam may normally be deflected by one or more movable mirror provided in the laser beam path between the laser beam source and the
work plate 5 onto which the powder material is arranged which is to be fused by the laser beam. Thecontrol unit 10 may manage the deflection of the mirrors so as to steer the laser beam to a predetermined position on thework plate 5. - The
powder supply 6 may comprise the powder material to be provided on thework plate 5. The powder material may for instance be pure metals or metal alloys such as titanium, titanium alloys, aluminum, aluminum alloys, stainless steel, Co—Cr—W alloy, Ni-based alloys, Titanium aluminides, Niobium, silicon nitride, molybdenum disilicide and the like. - The powder distributor or powder feeding member 7 may be arranged to lay down a thin layer of the powder material on the
work plate 5. During manufacturing of the three-dimensional article thework plate 5 will be continuously lowered and rotated in relation to the energy beam source. In order to make this movement possible, thework plate 5 may in one embodiment of the invention be arranged movably in vertical direction, i.e., in the direction indicated by arrow P. This means that thework plate 5 may start in an initial position, and continuously rotate around anaxis 15 and move vertically along theaxis 15. Thework plate 5 may continuously be lowered and rotated while simultaneously providing new powder material for the formation of new cross sectional portions of the three-dimensional article. Means for lowering thework plate 5 may for instance be through a servo engine equipped with a gear, adjusting screws, and the like. The rotation may be performed with an electrical motor. - In
FIG. 8 it is depicted a flow chart of an example embodiment of a method according to the present invention. The method comprising afirst step 810 of providing at least one model of the three-dimensional article. The models may be a computer model generated via a CAD (Computer Aided Design) tool. The three-dimensional articles which are to be built may be equal or different to each other. - In a second step 820 a first powder layer is applied on a support structure. The support structure may be a
work plate 5. Thework plate 5 may be a removable or fixed build platform, a powder bed, a partially fused powder bed or a pre-manufactured part. The powder may be distributed evenly over thework plate 5 according to several methods. One way to distribute thepowder 3 is to let thepowder material 3 in thepowder supply 6 falling down onto thework plate 5. The powder supply may have an opening at its bottom facing thework plate 5, through which the powder may fall down to thework plate 5. A feeding member or rake 7 may ensure the powder material onto the work plate is provided uniformly to an essentially flat surface. The rake may be arranged stationary or movable. - A distance between a lower part of the rake 7 and the upper part of the
work plate 5 or previous powder layer may determine the thickness of powder distributed over thework plate 5. The powder layer thickness can easily be adjusted by adjusting the distance between the lower part of the rake and the previous layer or thework plate 5. - In a
third step 830 at least one energy beam is directing from at least one energy beam source, the energy beam source being an electromagnetic energy beam source and/or a charged particle beam source, over the powder layer causing the powder layer to fuse in first selected locations according to the model to form a first portion of the three-dimensional article. - The at least one energy beam may fuse the three-dimensional article with parallel scan lines so as to form a fusion zone extending in a direction perpendicular to an axis of rotation of the
work plate 5. - The first energy beam may be an electron beam or a laser beam. The beam is directed over the
work plate 5 from instructions given by thecontrol unit 10. In thecontrol unit 10 instructions for how to control thebeam source 1 for each portions of the three-dimensional article may be stored. - In various example embodiment of the present invention the scan lines in at least one layer of at least a first three-dimensional article are fused with a first energy beam from a first energy beam source and at least one layer of at least a second three-dimensional article is fused with a second energy beam from a second energy beam source. More than one energy beam source may be used for fusing the scan lines. A first energy beam may emanate from an electron beam source and the second energy beam from a laser source. The first and second energy beam sources may be of the same type, i.e., a first and second electron beam source or a first and second laser beam source. The first and second energy beam sources may be used in sequence or simultaneously.
- By using more than one energy beam source the build temperature of the three-dimensional build may more easily be maintained compared to if just one beam source is used. The reason for this is that two beam may be at more locations simultaneously than just one beam. Increasing the number of beam sources will further ease the control of the build temperature. By using a plurality of energy beam sources a first energy beam source may be used for melting the powder material and a second energy beam source may be used for heating the powder material in order to keep the build temperature within a predetermined temperature range.
- In a fourth step 840 a first portion of the powder layer is provided simultaneous as fusing a second portion of the powder layer, wherein the second portion of the powder layer is fused along a line perpendicular to a rotational axis of the support structure. According to the invention the powder application and fusion takes place simultaneously. The powder is applied at a first portion of the work table 5 while the fusion is taken place on a second portion of the work table 5. The fusion may in various example embodiments take place along a line perpendicular to the rotational axis of the
work plate 5. One example embodiment of a three dimensional article which is manufactured according to this invention where the fusion take place along a line perpendicular to the rotational axis is illustrated inFIG. 6 . InFIG. 6 the rotational axis is along the z-axis. The threedimensional part 600 which is to be manufactured is centered around the Z-axis. A work plate is inFIG. 6 rotating around the z-axis and simultaneously performing a downward movement depicted byarrow 610. Fusion may take place in an area denoted by 620. According to the invention a continuous slicing along Z is performed which may be described in a 2-dimensional angular coordinate system depicted at the bottom ofFIG. 6 . The three-dimensional article is sliced continuously according to both a rotation and a translation along the z-axis at the same time. Continuous representation for a slicing thickness, or work plate drop, of Zmax/4 per turn is used in this example embodiment. Obviously any slicing thickness may be used other than this exemplified Zmax/4. - In
FIG. 7 a continuous slicing along the radius of the three-dimensional article is performed instead of as inFIG. 6 along the z-axis. The threedimensional article 600 is identical inFIGS. 6 and 7 . The three dimensional article is sliced inFIG. 7 continuously according to a rotation along the X-axis. Abeam scan line 601 moves progressively from the inner to the outer radius. Contentious representation for a slicing thickness, or radial distance move, of Rmax/4 per turn. According to the invention a continuous slicing along the radius of the three-dimensional article is performed which may be described in a 2-dimensional angular coordinate system depicted at the bottom ofFIG. 6 . As can be seen, although the slicing mechanism is totally different inFIGS. 6 and 7 for the same three-dimensional object, the description in the relevant 2-dimensional angular coordinate system will be identical. - In another aspect of the invention it is provided a program element configured and arranged when executed on a computer to implement a method for forming at least one three-dimensional article through successive fusion of parts of a powder bed, which parts correspond to successive portions of the three-dimensional article. The program element may be installed in a computer readable storage medium. The computer readable storage medium may be the
control unit 10 or another distinct and separate control unit, as may be desirable.
