DETAILED DESCRIPTION OF CERTAIN EMBODIMENTS OF THE INVENTION Embodiments of this application pertain to Systems and processes for detecting problematic grid structure designs, and for correcting these designs to ensure buildability in an additive manufacturing tool. An object that measures is built using
BE2016 / 5979 of additive manufacturing techniques may, for example, comprise one or more grating structures. A grid structure may refer to ears structure which includes a number of openings (e.g. geometrically shaped openings) in the material. Accordingly, the grid structure may resemble a screen or other grating with intersecting lines, in some aspects the grid structure includes substantially straight lengths (to which Also referred to as "beams") building material, which forms a pattern of openings (eg, a shrinking pattern). Near the intersection of beams can be referred to as a node. For example, a honeycomb structure can be an example of a grid.
The inventors have identified several probabilities that arise in producing designed grid structures. Designers often have total freedom in designing a grid structure. Moreover, a finite element analysis (FEA), when generating a grid structure, does not take into account. with the buildability of the generated structure, therefore probes that occur during the production of raster structures often include inadequate support for long horizontal lines or other areas that are not self-supporting, such as downwardly hanging ends on the bus edges of the structure, [802Ö] To these and other probabilities identified by the inventors to be taught, Systems and methods are described for detecting and correcting non-manufacturable features of frames, generally these inventive Systems and methods include receiving a digital graphics support. ng of a grid structure, as described, is described in International Patent Publication No. WO 2015/022341, which is incorporated herein in its entirety by reference. in some embodiments, the graphical representation of the grid structure includes a skefet representation of the grid structure design before the construction process is performed. in particular, the graphic representation may include lines reflecting the position and orientation of the proper building material (e.g. beams) used to form the grid structure when produced (e.g. using additive manufacturing techniques). However, the graphic representation may indicate the quantity (eg thickness, actual dimensions, etc.) of construction material along each of the
BE2016 / 5979 does not show lines. Accordingly, the graphic representation may not represent the dimensions of the bays of the grid structure. On the other hand, the graphic representation of the grid structure may only give an approximate indication of the length over which the building material must be used to form the grid structure during production, as discussed further below.
(002ij) In some embodiments, to ensure the buildability of the raster structure, a computer system anaphyses the digital graphic representation of the raster structure to identify potential (eg lines, bays, etc.) of the digital graphic representation that are not self-supporting or would know those fouls when built using additive manufacturing techniques, for example, the computer system analyzes the digital graphical representation of the grid structure to identify lines that do not conform to a threshold angle of an XY plane of the grid structure, in particular objects, with additive manufacturing, typically built low per layer on a building platform, with a whey-oriented orientation of the object during construction process relative to the building platform Hot XY plane refers to any box corresponding to (eg, parallel to) one single layer and that is parallel to the construction platform. The Z axis is the axis right on the build platform, Correspondingly, the angle of a line relative to an XY plane of the grid structure is the angle formed between the line and the XY plane. For lines parallel to the XY-vfak, the angle formed is nui. For lines intersecting the XY plane, the angle formed is the smaller of the two adjacent angles formed by the cutting. The angle of the line can be referred to as the “overhang angle”, or the self-supporting © angle, and indicates the angle when the structure is self-supporting during the construction process. for example, if the line's overhang angle is wider than the drempoi angle, the line may be self-supporting and thus the line is considered to be manufacturable. Such lines can be mainly or substantially vertical lines relative to the building platform.
jWZj The computer system determines whether such angles of lines do not meet the threshold angle (eg, the angles of the lines are smaller than the threshold angle, as horizontal lines representing horizontal bays), Such lines may
BE2016 / 5979 are mainly or essentially horizontal lines relative to the construction platform. Such lines that do not meet the threshold angle can be referred to as non-conforming lines. in some embodiments, the computer system then further analyzes non-conforming lines to determine whether they can be produced in the context of the grid structure.
In addition to the angle of the line, for example, the length and thickness of the actual building material (e.g. bays) that the line forms contemplates whether the non-conforming line ai will be self-supporting during an add-on production process. The shorter the bays of a grid structure, the more likely it is, for example, that it will be self-supporting .. Lines represent the length of the construction material for the line (eg the length of an effective beam, such as a horizontal beam, of a Grid structure produced) As discussed, however, lines are only a mathematical representation of the grating structure to be built, in particular the lines do not indicate the beam thickness (eg thickness of the building material hanging along the line) for the line. previously hidden and only available in a later step of the design and production process, as described in International Patent Publication No. WO 201 5/022341. in particular, the beam thickness and the orientation of adjacent bays, represented by adjacent lines, can have a significant impact on the buildability of bays represented by lines that do not meet the threshold angle. Accordingly, the Systems and Methods described here determine whether one or more bays represented by a non-conforming line (e.g. non-conforming bays) are self-supporting, in addition to building the length (e.g., the horizontal component of the length of the non-conforming line parallel to the XY-viak) of the line representing the beam, to analyze the beam thickness and / or the orientation of adjacent bays. Adjoining bays can refer to bays that are connected to (e.g. share a node with) the given bar. Adjoining downward facing bays may refer to bays extending downwardly to a building platform relative to the given bay. Adjacent upwardly facing bays may refer to near bays extending in an upward direction of a building platform relative to the given beam. In some embodiments, the computer system, if one
BE2016 / 5979 defined bay is indicated as being non-compliant, and adjacent downward facing bays are also designated as being non-compliant, the Length of the specified bay all adjacent adjacent downward facing bays that are not compliant (e.g., and their non - conforming downward facing neighbors also reach a conforming near downward facing neighbor) to determine the corresponding length of the overhang for the bays. in some embodiments, if there are no adjacent downward facing bays (e.g., some adjacent upward facing bays) for a beam represented by a line that does not pass at the threshold angle, the bay can be identified as being non-self-supporting.
A computer system may use those procedures indicated here to determine whether or not a whey-engineered non-conforming baik ai is self-supporting. In some embodiments, the computer system may provide a user with an indication (e.g., in a graphical user interface on a screen) that a baik ai is self-supporting. Furthermore, the computer system, in some embodiments, can correct bays that have been identified as being non-self-supporting (eg, automatically).
[MZSj in some embodiments, the computer system determines an actual length of the structure (eg, baik) that will be formed during the actual production process for a non-conforming line, in some embodiments, for example, the computer system draws values based on the baik thicknesses (eg, the half of the beam thickness (baik diameter), the baik thickness, the radius of a baik (e.g. beam diameter / 2 * cos (aifa) in which alpha is the book between the non-conforming baik and the adjacent baik, etc.) of the bays adjacent to the nonconforming beam of the length of the corresponding nonconforming line {which is also referred to as "line length" *) of the nonconforming beam to determine an effective length of the structure (eg, effective beam length) which will be formed during the actual production process. Based on the type of material used for the construction site, the computer system compares the effective length of the bay structure with a predetermined maximum sway load bay length, if the actual bay length is greater than the predetermined maximum sway load bay length, it can
BE2016 / 5979 computer system identify the non-conforming beam as being irregular or indicated as being non-self-supporting.
teOiSs In some embodiments, the computer system, in the pleats vert to use the values based on the beam thicknesses of adjacent beams, may consider connection thicknesses when analyzing the buildability of a non-conforming beam. In particular, in some axle legs, joint thickness can be used to determine whether or not a non-conforming beam is self-supporting if such joint thickness information is available; otherwise, values based on the beam thickness of adjacent beams are used .
.1.0 in particular has produced a {eg. using additive manufacturing) component inherently a joint thickness where two beams intersect. This joint thickness can act as a rounding (e.g. rounding a corner) that can reinforce areas of high stress in the design. Such joint thickness information can be determined at a junction connecting a non-conforming beam! with its adjacent bars In the digital graphic representation of the grid structure. For example, for a given node, the connection thickness may include a thickness of the node or a street of a pile at that node corresponding to the thickness of the building material used at the node to build the grid structure fe. If the connection thickness is used as a criterion, the computer system calculates the effective working length {e.g. actual overhang) instead of the line length of the nonconforming beam, less the joint thickness of each node common to each adjacent beam. The computer system can compare the actual bay length to a predetermined maximum to determine the buildability of that non-conforming bay. If the effective bay length is greater than that predetermined maximum self-supporting bay length, the non-conforming beam may be identified by the computer system as being irregular or as self-supporting.
In some embodiments, the computer system can modify vlsueei iijnon to correspond to non-conforming or non-self-supporting beams in the design, to assist the user in identifying them in the graphic

V presentation of the design. Furthermore, in some embodiments, the computer system may correct any beam identified as being non-conforming or non-self-supporting (e.g., automatic), in some embodiments, the computer system may, for example, adjust the connection thickness (e.g., bent) at nodes that are common with adjacent bays in order to delay the actual length of the non-conforming beam, Additionally or alternatively, the computer system may adjust the design by moving nodes closer together to reduce the line length of the irregular beam fe, in some embodiments the computer system , additionally or alternatively, adjust the thickness of adjacent bays (eg, bent) to reduce the actual length of the non-conforming beam. In these embodiments, the angles of adjacent lines (e.g., adjacent bays) may change due to the shorter length of the non-conforming beam, accordingly, the computer system (e.g., iteratively) can re-analyze the new angles to ensure it is satisfactory of craftability specifications, [oozsh Figure 1 is a preview of a graphical representation of part of a grid structure in accordance with one or embodiments. As shown, the graphic representation includes a 2D representation of the raster structure 100. The vertical axis of the graphic representation corresponds to the Z axis discussed here. The horizontal axis of the graphic representation corresponds to a cross section of the XY-viak discussed here. in particular, the graphical representation is a cross-section of the grating structure 100 along a plane parallel to the Z axis. This portion of the grid structure 100 includes two diagonally opposite lines on the left side, diagonal bays 102A and 102D.
Grid structure 100 also includes two diagonally opposite lines on the right side of the structure, diagonal bays 102B and 102C. Each pear diagonal bays converge In an end point (eg, node) of a non-conforming beam 104 (shown as being horizontal), as shown in Figure 1. Because each of the diagonal bays 1Ö2A-102D runs sharply diagonally! as it extends away from the non-conforming beam 104, each of the diagonal bays 102A-W2D has an angle greater than the threshold angle for lines. It is easy to see that the diagonal bays 102A-1Ö2D meet the buildability requirements because they
BE2016 / 5979 are self-supporting. On the other hand, it is not clear at first whether the non-conforming beam 104 can or cannot be printed because the buildability of that particular beam depends on the physical properties (such as beam thickness, joint thickness, etc.) of the diagonal beams 102A-102D proposed. through the diagonaa! opposite lines, Thus, in order to determine whether the non-conforming beam 104 kart is printed in the beam design, the physical properties (eg dimensions, joint thickness, beam thickness, and 2.) must be considered in adjacent beams 102A-1Ö2D FIG. 2 is an example of the graphical representation of FIG. 1 showing 1.0 bar thicknesses placed above the graphical representation of the grid structure 100. The bar thicknesses visually show how the grid structure will be physically formed during production. As shown, the diagonal baik 102A has an added baik thickness 202A. This added beam thickness provides thickness to the line which is not similar. Similarly, each diagonal beam 1Ö2B-1Ö2D has a corresponding beam thickness 2Ö2B-202D added to the token. The non-conforming beam 104 has a bay thickness 204 which is also shown in Figure 2. As discussed above, the thickness of adjacent bays can often have an Impact on the tolerability of a non-conforming beam because the thickness of the adjacent bays the actual length of the non-compliant beam can be reduced. This impact is illustrated in figure 2, figure 2 shows a line 206, which reflects the length of the drawn line representing the non-compliant bay 104. As shown, the line length 206 extends from each end point (eg, node) to the other end point (eg, node) on the nonconforming baik 104. However, this distance gives the actual length of the ninth25 conforming baik 104 in the physical world not accurate weather, as it does not take into account the baik thickness of adjacent bays. Accordingly, a second dimension, the effective length 210, is also shown in Figure 2. The effective length 210 is determined by subtracting values based on the beam thicknesses 208A and 20S from the notch length 206 of the non-conforming beam.
104. As can be seen in figure 2, the actual length is somewhat smaller than the line length, and this effective length 210 is a useful indicator of whether or not the nonconforming bay 104 is self-supporting (eg or he meets the
BE2016 / 5979 buildability requirements of the additive production equipment) during and after the production process.
Figure 3 is an example of the graphical representation of Figure 1 illustrating how increasing the baik thickness in adjacent bays can affect the effective length of a horizontal bar. As shown, the scenario illustrated in Figure 3 is strongly aligned with that shown in Figure 2 in Figure 3, however, the thickness of each of the diagonal bays 302A-302D is significantly greater than the thickness of the diagonal bays shown in Figure 2. Therefore, the effective length of the non-conforming beam 104 and the effective length of the non-conforming beam in Figure 2. As was the case in Figure 2, the effective length is determined by subtracting the values based on the beam thicknesses 308A and 308B from the line length 206 of the nonconforming beam 104. in this example, the effective length decreases to such an extent that it is within the buildability parameters for the machine and construction material, and it is accordingly identified as being "OK in FIG. 3. Thus, as illustrated by the example provided in FIG. 3, when the thickness of adjacent bays is considered in the context of a graphical preview of the grid, a non-conforming beam that may initially not be self-supporting, in fact structurally sprung to be produced successfully without any additional support structure.
(sssij In Figures 2 to 3 above, the baik thickness of adjacent bays was used to determine an effective length (eg, effective horizontal length) of the non-conforming beam 104. Baik thickness Is only one way in which an effective length of the non-conforming beam can be determined in a token Another way this can be determined is by using the templation thickness as parameter As explained above, a printed part inherently has a connection thickness in the pleats where two bays meet, this connection thickness can work as a rounding (eg a rounding of a book) that can strengthen areas of high stress in the design. Figure 4 is an example of the graphical pre-selection of Figure 1 showing how the connection thickness can be used to determine the actual length fe of non-conforming beam 104. As shown in Figure 4, the grid structure 100 includes
BE2016 / 5979 a non-conforming beam 104 meeting with diagonal beams 102A-102D, each of which has corresponding beam thicknesses 302A-302D. Additionally, Figure 4 illustrates connections 412A and 412B, which are represented as circles (e.g. corresponding to spheres at the nodes) in the drawing. Connections 412A and 412B extend quite near the center of the non-conforming beam 104, as reflected by connection thickness 408A and connection thickness 408B (e.g., penalties of connections 412A and 412B, respectively). in this configuratle, the actual length 410 of the non-conforming beam 104 is determined by subtracting the total joint thicknesses from the length 206, Since the residual actual length is relatively small, it can be determined that the non-conforming beam 104 satisfies the applicable buildability sizers.
As noted above, the inventors have recognized that certain modifications may be made to improve the buildability of a grid structure design, Figure 5 provides an illustrative way of improving the buildability of a grid structure. in particular, Figure 5 is an iltoslrat of an increase in the joint thicknesses of joints that can be used to make a non-conforming beam meet buildable hero requirements As shown in Figure 5, the dimensions of joints S12A and S12B were increased relative to of the joints 412A and 412B shown in Figure 4. Thus, if the joint thicknesses of the joints shown in Figure 4 are not sufficient to ensure that the non-conforming bell 104 meets the buildability requirements of a particular material and machine, the connection thicknesses can be adjusted (eg enlarged den) in such a way that the actual length 510 decreases even more in the hope that the custom © design will meet the buildability of the machine and material used to complete the task, to033j In addition to changing the joint thickness of joints, another technique can be used to improve the buildability of the horizontal beam. Figure 6 is an illustrais® of another adaptation to the drawing that can be made to allow the grid structure to meet buildability needs. As shown, the frame structure 100 includes one
BE2016 / 5979 Changed Baik 604. In this example, the line length 606 of Baik 604 was changed by blanking the connection points on each side of Baik 604. As a result of changing the intersection points between the beam and the adjacent bays, the angle of each of the adjacent bays decreases,
S Accordingly, the adjacent bays can be rechecked to confirm that they are still above the threshold angle for the machine on materials to be used. Thus, in this whey example, the buildability of the beam 604 can be improved without the need to change the thickness of the joints or the adjacent bays.
1 (3 The examples illustrated above can be performed using Computer software running on a computer system. Figure 7 is a flowchart illustrating a computer-implemented method for analyzing a graphical representation of a raster structure for non- identifying self-supporting debris in accordance with one or more embodiments The process begins at blök 702, in which lines ln the graphical representation of the grid structure are located which lie above the threshold angle in the XY plane, The process then proceeds to blök 704, where the detected lines that meet the buildability requirements in the system are identified as being those that meet the buildability requirements, the process will go to block 706. There, a line in the token, which is below the threshold angle, is selected to be considered as being a riet-conf The process then proceeds to block 706, where the actual length of the line is calculated based on the drawn length of the line and the thickness or joint thickness of adjacent lines.
Furthermore, in biok 710, it is determined whether or not the selected line ai meets buildability requirements on the basis of its calculated actual length. The process then proceeds near Besisssingsbiok 712, where, if the selected line meets buildability requirements, the reed process returns to block 706. wear another line is selected to be considered. If, however, in decision step 712, the selected line is not. meets buildability requirements, the process continues to biok 714. There, the token is modified (eg by the computer system) (or optionally the line is marked using a visual indication such as
BE2016 / 5979 discussed) in such a way that the selected line can meet the buildability requirements. As noted previously, various adjustments can be made to the token in such a way that an irregular line is brought into line with the requirements. As noted above, these changes may be a change in beam thickness, a change in connection thickness, or Also, an alteration of the end points of a dozen, Embodiments of the invention can be used within a 3D object design and production system. Figure 8 shows an example .1 (3) of a computer environment suitable for effecting the design and production of 3D objects. The environment includes a system 800. The system 800 includes one or more computers 802a-802d, which, for example, knowing any Workstation, server, or other computer equipment capable of processing information In some aspects, any computer 8Q2a-802d may be connected to a network 805 through any convenient communication technology (eg, an Internet protocol). (eg the Internet) Accordingly, computers 802a-882d can exchange data (eg software, digital representations of 3D objects, commands or instructions to control an additive production device, and 2.) with each other over the network 805.
The system 800 further includes one or more additive production tools (eg,
3D printers) 808a ~ 808b. As shown, the additive manufacturing appliance 808a is directly connected to a computer 802d (and via computer 802d connected to computers 802a-802c via the network 805) and additive production appliance 808b is connected to the computers 802a-802d via the network 805.

3 Inventive Step
3.1 Document D1 discloses (the features in strikethrough formatting considered to be absent from this disclosure) Computer-readable medium that stores instructions that when executed by a computer system processor, ensure that the computer system performs a method for analyzing a graphical representation of our three-dimensional structure to identify non-said dragend areas (section 4.1), the method comprising the following:
XY ^ vtal ^ iehdeieeUe-dae-eee-dFempeUteek-where-the-flin-a-kp4eegte iiisüaifci varbmdingsdifd: orwar ^ iVT-Wfkeiijke4eegte-va «-d ^ deefee4'de - 4yrH - eft actual length, whether the line detected meets buildability requirements (page 98: 5, right-hand column, last sentence),
3.2 The prior art does foresee deriving buildabiuty information from line iength. This length Is however not based on the actual length as determined with due consideration of the thickness of the line or the joint, as required by claim 12. Other prior art relates to angle threshold or overlap, but does not base its determination on an updated and corrected line length taking into account the actual influence of thickness.
3 3 The subject-matter is therefore novel.
3 4 The problem to be solved can be seen as hew to avoid the generation of unneeded support structures close when a bridge suffices.

WRITTEN OPINION (SEPARATE SKEET)
3 5 It is considered that the person skilled in the art when departing from the prior art at hand would rather tune parameters or as In D1 establish a maximum length rather than correcting the length on the basis of the thickness information,
3.6 An Inventive step can thus be acknowledged,
3.7 The same reasoning applies mutatis mutandis to the subject-matter of corresponding claims 13.14.
