Description

Title: Apparatus for producing an object by means of additive manufacturing
Description
The invention relates to an apparatus for producing an object by means of additive manufacturing, comprising a process chamber for receiving a bath of material which can be solidified; a solidifying device for solidifying a selective part of the material; and a support structure being movable in a shaft for positioning the object in relation to the bath of material. 3D printing or additive manufacturing refers to any of various processes for manufacturing a three-dimensional object. Traditional techniques like injection molding can be less expensive for manufacturing, for example, polymer products in high quantities, but 3D printing or additive manufacturing can be faster, more flexible and less expensive when producing relatively small quantities of three-dimensional objects.
It is anticipated that additive manufacturing becomes more and more important in the future, as the increasing competitive pressure forces companies to not only manufacture more economically with a constant high product quality but also to save time and costs in the area of product development. The life span of products is continuously shortened. In addition to product quality and product costs, the moment of market introduction is becoming increasingly important for the success of a product.
The three-dimensional object may be produced by selectively solidifying, in a layer-like fashion, a powder or liquid material to produce a three-dimensional, 3D, object. In particular, a computer controlled additive manufacturing apparatus may be used which sequentially sinters a plurality of layers to build the desired object in a layer-by-layer fashion. Primarily additive processes are used, in which successive layers of material are laid down under computer control. These objects can be of almost any shape or geometry, and are produced from a 3D model or other electronic data source.
In order to print a three-dimensional object, a printable model is to be created with a computer design package or via a 3D scanner, for example. Usually, the input is a 3D CAD file such as an STL file, a STEP file or a IGS file. Before printing the object from a CAD file, the file is to be processed by a piece of software, which converts the model into a series of thin subsequent layers. Further, apparatus settings and vectors are generated for controlling the creation of each of the subsequent layers. A laser comprised in the computer controlled additive manufacturing apparatus follows these settings and vectors to solidify successive layers of material to build the 3D object from a series of cross sections. These layers, which correspond to the virtual cross sections from the CAD model, are during this process joined or fused at the same time to create the final 3D object.
In a known apparatus, a bath of material is laid down on the movable support structure, and the laser is used to form a first layer of the object to be formed. Then the movable support structure is lowered by means of a spindle for a given distance, the bath of material is replenished, and the laser is used to form an additional layer on top of the first layer already formed.
To reduce operational costs of the apparatus, it is an object to fully utilize the capacity of the apparatus and, at the same time, make sure that the total production lead time of a three dimensional object is minimized, i.e. the production queue is minimized.
One of the challenges in the manufacturing of three dimensional objects, in particular in additive manufacturing of metal objects, is how to produce accurate and reproducible objects. The known apparatus does not satisfy the ever increasing additive manufacturing demands, in particular with accuracy and reproducibility of the objects produced.
It is therefore an object of the invention to provide an apparatus for producing an object by means of additive manufacturing with improved characteristics, in particular wherein an object may be produced with more accuracy and improved reproducibility.
To this end, the invention provides an apparatus for producing an object by means of additive manufacturing according to claim 1. The apparatus for producing an object by means of additive manufacturing according to the invention comprises a process chamber for receiving a bath of material which can be solidified; a solidifying device for solidifying a selective part of the material; and a support structure being movable in a shaft for positioning the object in relation to the bath of material. The accuracy and reproducibility of the apparatus is improved due to that at least said support structure is provided with guiding means for guiding the support structure along the shaft during movement thereof. The guiding means ensure that the movable support structure may be positioned more accurately, such that also the formation of layers during forming of the product may be performed with more accuracy. Ultimately, this makes it possible to produce objects with more reproducible results. With this, the object of the invention is achieved.
The guiding means are in an embodiment in contact with the shaft. In some embodiments, an interspace may be formed between the guiding means and the shaft, i.e. the guiding means are free from contact with the shaft.
The guiding means may comprise at least one of an air bearing, magnetic bearing, hydrostatic bearing, dynamical bearing, a sliding block, and/or a wheel element.
In an embodiment, the guiding means comprises at least one wheel element connected to the support structure, and displaceable along a first wall of the shaft. A wheel element provides for a relatively cost-effective guiding means. The at least one wheel element may be connected to the movable support structure, such that the wheel element may roll along the first wall of the shaft. It should be noted that the term first wall of the shaft also includes elements directly and fixedly connected thereto. For instance, the first wall of the shaft may be provided with a guide bar or guiding profile, and the wheel element may be in contact with the guide bar or the guiding profile. This is to be understood that the wheel element is displaceable along a first wall of the shaft.
In an embodiment, the support structure comprises a suspension element for the wheel element. The suspension may be a rigid suspension structure that connects the wheel element to the support structure. This aids in compensating for tolerances, such as for instance due to thermal expansion, or may improve the accuracy of the guiding means in general. However, a more flexible connection, is also conceivable, as will be explained below.
In an embodiment, the suspension element is movably, in particular pivotally connected to the support structure. This allows the support structure to better follow the wall of the shaft, and thus increases the ease and accuracy with which the support structure may be moved.
In an embodiment, the guiding means comprise at least one further wheel element connected to the support structure. In particular, the further wheel element may be displaceable along the first wall of the shaft.
In an embodiment, the at least one further wheel element is displaceable along a second wall of the shaft. The second wall differs from the first wall. By providing further wheel elements, displaceable along the first or the second wall, the accuracy of the positioning of the support structure is improved, since it reduces the degrees of freedom of the movable platform.
The further wheel element may be embodied, without limitation, as described above with respect to the wheel element. This includes the possibility of providing a further suspension element, including a further suspension element that is pivotally connected to the support structure, as well as the positioning of said further wheel element onto the same structural components as the first wheel element..
In an embodiment, the apparatus comprises a further suspension element for the at least one further wheel element, said further suspension element being movably, in particular pivotally connected to the support structure, and wherein the suspension element and the further suspension element are movably coupled to each other by means of a coupling element. A coupling element is provided, which is attached to both the suspension element and the further suspension element. This means that movement of the first suspension element leads to movement of the further suspension element, via the coupling element. This allows for a more smooth and accurate guiding of the support structure along the shaft.
In an embodiment, the coupling element comprises a spring and/or damping member. This provides for a relatively cost-effective coupling member. In addition the spring and/or damping member also ensures that the wheel element and the further wheel element are biased or urged to their respective wall of the shaft, such that smooth and accurate displacement along the shaft is possible.
In an embodiment, the suspension element and the further suspension element are interlinked to be pivotably movable in opposite directions. This ensures that the support platform itself is positioned centrally between the first wall and the second wall. In particular, when the first wall of the shaft is opposed to the second wall, it allows for a more accurate positioning of the support platform in between the first and second wall, since production tolerances of the shaft are levelled out by the guiding mechanism described above.
Embodiments of the invention will be described in the following in connection with the Figures. In the Figures
Figure 1 is an overview of an apparatus according to the present invention for additive manufacturing an object.
Figure 2 is a side view of an embodiment of the movable support according to the invention;
Figure 3 is a top view of an embodiment of the movable support according to the invention;
Figure 4 is a perspective view of an embodiment of the movable support according to the invention;
Figure 5 is a side view of an embodiment of the movable support according to the invention;
Figure 1 shows an overview of an apparatus 1 for producing an object 2 by means of additive manufacturing. The apparatus 1 is built from several frame parts 11, 12, 13. The apparatus comprises a process chamber 3 for receiving a bath of material 4 which can be solidified. In a lower frame part 11, a shaft is formed, wherein a support 5 is provided for positioning the object 2 in relation to the surface level L of the bath of material 4. The support 5 is movably provided in the shaft 50, in a direction generally indicated by arrow Z, such that after solidifying a layer, the support 5 may be lowered, and a further layer of material may be solidified on top of the part of the object 2 already formed. In a top part 13 of the apparatus 1, a solidifying device 7 is provided for solidifying a selective part of the material. In the embodiment shown, the solidifying device 7 is a laser device, which is arranged for producing electromagnetic radiation in the form of laser light, in order to melt a powdered material provided on the support, which then, after cooling forms a solidified part of the object to be produced. However, the invention is not limited to the type of solidifying device. As can be seen, the electromagnetic radiation 71 emitted by the laser device 7 is deflected by means of a deflector unit 74, which uses a rotatable optical element 75 to direct the emitted radiation 71 towards the surface L of the layer of material 4. Depending on the position of the deflector unit 74, radiation may be emitted, as an example, according to rays 72, 73.
Fig. 2 shows a schematic side view of an embodiment of the support 5 according to the invention. Fig. 2 shows the movable support 5, having a build platform 52 and a spindle 51, which is movably provided, in a direction indicated by arrow Z, within a shaft 50. Now referring back to Fig. 1, it can be seen that the shaft 50 is part of the lower frame 11, and that the movable support 5 is movable within the shaft 50 for positioning the build platform 52 at a desired height in order to produce the object 2. Now referring to Fig. 2, it can be seen that the support 5, and in particular the build platform 52, is provided with a first wheel element 54 and a second wheel element 55, both of which are displaceable along opposite walls of the shaft 50. Thus, the support structure 5 is provided with guiding means 54, 55 in contact with the shaft 50 for guiding the support structure 5 along the shaft 50 during movement thereof.
Fig. 3 shows a top view of an embodiment of the movable support 5 having guiding means 54-59, preferably in the form of wheel elements. In total, six guiding elements 54-59, which can be wheel elements 54-59, are visible in Fig. 3, although it is conceivable to use more or less guiding elements. Furthermore, it can be seen that pairs of opposing guiding elements are formed here. For instance, guiding element 54 is positioned opposite to guiding element 55, guiding element 56 is opposed to guiding element 57, and guiding element 58 is opposed to guiding element 59. The positioning of these pairs of guiding elements 54-59, preferably in the form of guiding wheels 54-59, aids in constraining the degrees of freedom. It is noted that a small offset may be present, between opposed guiding elements, without substantially affecting the constraining in the degrees of freedom.
Fig. 4 shows a schematic view in perspective of a further embodiment of the build platform 52 of the movable support, having all guiding elements as described with respect to the top view of Fig. 3, and having additional pairs of guiding elements, for which only a single guiding element 64, 66 is visible in Fig. 4. It is noted that directly opposite each of the two guiding elements 64, 66 a further guiding element, preferably in the form of a guiding wheel, is provided. The further guiding elements are positioned directly below the guiding elements 57, 55 depicted in Fig. 3, such that opposing pairs of guiding elements are formed.
In principle any solid object has a total of 6 degrees of freedom (DOF): 3 DOF for translational movements and 3 DOF for rotational movements. By using the pairs of guiding elements 54-59 in Fig. 3, and 54-59, 64, 66 in Fig. 4, the number of DOF are reduced, by constraining certain movements. The guiding means shown in Fig. 3 would constrain any DOF related to translational movement and/or rotational movement within a plane defined by the surface of the build platform 52, i.e. within the plane defined by the drawing of Fig. 3. The guiding means shown in, and described with respect to, Fig. 4, having a total of 5 pairs of guiding elements, would additionally constrain the remaining DOF related to rotational movement, such that only the DOF related to movement in the axial direction (indicated by arrow D), i.e. the desired movement of the build platform 52, remains unconstrained.
Fig. 5 schematically shows an embodiment of a pair of guiding elements for a movable support structure. Fig. 5 schematically shows the shaft in the form of two opposed wall parts 50, 50’, within which the build platform 52 is movably provided. The build platform 52 is movable in the direction Z by means of, for example, a spindle, as also indicated in Figs. 1 and 2. Other ways of driving the support structure 52 in the direction Z are conceivable of course, and the way of driving is not limited to the invention.
According to the invention, guiding elements in the form of a wheel element 54 and a further wheel element 55 are provided. The wheel element 54 is connected to the build platform 52, by means of a suspension element 541, and is movable along a first wall 50 of the shaft. The further wheel element 55 is also connected to the build platform by means of a further suspension element 551, and is movable along a second wall 50’ of the shaft. The first wall 50 of the shaft is directly opposed to the second wall 50’, and is facing said second wall 50’. The suspension elements 541, 551 are each pivotally connected to the build platform 52, such that pivotal movement about axes 542, 552, respectively, of the suspension elements 541, 551 is possible. As can be seen in Fig. 5, the suspension element 541 and the further suspension element 551 are movably coupled to each other by means of a coupling element 45, in the form of a hinge element 45. The coupling element furthermore comprises a spring and/or damping member 46, which is connected to the build platform 52 of the movable support structure and, in the embodiment shown in Fig. 5, to the further suspension element 551. It is noted that the spring and/or damping member 46 may additionally or alternatively be connected to the suspension element 541.
The coupling between the suspension element 541 and the further suspension element 551 is such that these elements 541, 551 are interlinked to be pivotably movable in opposite directions. The spring and/or damping element 46 is designed to be a compression spring, which presses onto the hinge 45, and biases or urges the wheel elements 54, 55 outwards, such that both wheels 54, 55 are in good contact with their respective wall 50, 50’. The construction described above implies that if the support structure experiences thermal expansion, for instance in the direction indicated by arrow X, then the axes 542, 552 will be positioned further apart, which, in the prior art, may lead to uncertainties in the exact position of the build platform 52. With the structure described above, the compression spring 46 urges the wheel elements 54, 55 into contact with their respective wall parts 50, 50’ with the center part of the support structure 52 being positioned exactly in between the wall parts 50, 50’. Thus, the guiding means described here with respect to Fig. 5 may be used to ensure an accurate and reproducible positioning of the build platform 52, even in cases where temperature gradients lead to thermal expansion of the build platform 52 and/or the shaft.
It is noted that all five pairs of guiding elements described and shown in Fig. 4 are, in an embodiment, construed as the pair of guiding elements shown in Fig. 5, enabling an accurate and reproducible positioning in all translational and rotational DOF, except for translational movement in the Z direction.
It will be clear to those skilled in the art, that the invention is described above by means of several embodiments. However, the invention is not limited to these embodiments. The desired protection is defined by the appended claims.
