Mold DemoCreating Parting Line: Load the included Vampire Boy model.Go to Tab > Moldable PartCreate a parting line curve by activating the mold toolbar feature by selecting theMoldable Part tab. Then click on the Parting Line Curve icon on the toolbar andFreeform Mold Demo -1-click on the Show Parting Line Color icon to show the parting line. The arrow on the screen indicates the mold pull direction. You can change the direction by clicking onthe Set Direction icon to check the best parting line solution. Once everything is set, click on Apply to create the parting line curve.The parting line curve direction is already set for this model, but be sure the parting line draft angle is set to zero. To check if the draft angle is set to zero for this evaluation, go to Tools > Option > Parting line draft angle. For using the Parting Line tool, always set the draft to zero so that you will get a clear blue line. If the draft is not set to zero, the parting line curve will not be created in the correct location.Currently, the mold pull direction is already set correctly. If you want to show people the different pull direction, click on the Set Direction icon to change the setting.Showing Curvature PlotFreeform Mold Demo -2-The parting line curve is very dense and trying to pick up all the details necessary. If you want to look at the level of quality of the parting line curve, you can turn on the curvature plot and create a curvature plot of each curve. Go to:View > Design Curves -> Create Curvature Plots. Then click on the parting line curves on the model. By default, the plot is set in 2D to show the noise in Z direction only; you can also set to show the noise in X and Y direction by changing the 2D Curvature icon to 3D Curvature icon on the Dynabar. [as shown below]2D curvature plot showing on noise in Z directionFreeform Mold Demo -3-3D curvature plot showing noise in X and Y directionIn most cases, you will only want to use the 2D curvature plot in the Z direction. The number shown on the curvature plot indicates the minimum radius curvature of the curve. This number can be used to determine the tool size for machining in the future. To find the tool radius, simply take the inverse of the curvature value. The equation used in this calculation is shown below:C = 1/R ; C = curvature, R = radiusEditing Parting Line CurveFreeform Mold Demo -4-machining. To avoid this problem, I am going to smooth the parting line curve. Tosmooth the parting line curve, click on the Select icon on the toolbar and then clickon the parting line curve. Change the number on the Points box to reduce thenumber of points on the curve. In most cases, you can reduce the number of point by halfthen refit it. Be aware that it may have drifted from sharp details in the XY plane.Usually, after reducing the points on the parting line, the parting line will likely still be very close to the original parting line. However it does not work for every case. In most situations, you can just reduce the points and refit it just for demo purposes.Now I will refit the parting line curve by clicking on the Fit CurveFreeform Mold Demo -5-to Clay tool under the same flyout as the Parting Line Curve tool. Then click on the parting line curve. Refitting the curve will remove the curvature plot information because the refitted curve is actually a new curve. Therefore, you have to put the curvature plot back on to see the new result. Now you can see that the refitted curves have a low curvature and noise.You can also use the Smooth Curve tool under the Parting Line Curve tool to smooth out the curves. After you are satisfied with the result, you can turn off the curvature plot.Fixing DraftFor this model, there is a draft problem. To demonstrate the draft-fixing feature, youFreeform Mold Demo -6-should point out some draft problems on the model. Indicate the areas behind the nose and the teeth (Create Parting Line actually surrounded these areas with curves, which can be deleted at this time.)The next thing to do is to fix draft. As you can see on the screen, the nose and the tooth have a draft issue. To correct the problem, I can either add material or remove material to correct the problem under the Draft option.Go back to create moldable part and then select Draft tool on the toolbar. Then click on the parting line. The problem areas are shown in blue. Now I want to add material behind the nose to the fix the draft instead of chopping off the nose to fix the draft. So I click on the Add Clay , but hold to the parting line by clicking thePreserver Parting line icon then click Apply.The changes on the model should be very quick, so you can say a few words or gesturing with your hands, then the changes should be done. The fixed model is shown below.Freeform Mold Demo -7-Shelling The ModelClick on the “d” key to show the model in See Through mode, and indicate that it is a solid model. Click the “d” key once more to return to an opaque view.Now you can shell the model. Click on Shell on the toolbar. For this model, I want a 4mm shell. Then change the number in the Shell Thickness box on the dynabarto 4 and click Apply.Freeform Mold Demo -8-The shelling process should be done very quickly. While waiting for the model to be shelled, you can talk about the benefit of this feature. After the shell is complete, click on “d” on the keyboard again to activate the dotted mode for showing the part thickness.Click “d” to change to dotted mode to show part thicknessYou can check the part thickness by using the ruler feature. Go to Tools > Ruler or click“r” on the keyboard to activate the ruler feature. Then select Measure Thicknessicon on the Dynabar and measure the part thickness.Freeform Mold Demo -9-Creating Split JointFor better visual, turn off the clay by clicking on Blank Clay icon. The resulting screen is shown above. By turning off the clay, you can see the glue joint that you will create on the screen.Now I want to be able to create the shiplap joint. I go down to the Split Joint tool and pick on the curve on the screen. It will create a butt joint by default first (shown below) then I will create a shiplap joint on the modelFreeform Mold Demo -10-.After selecting the curve on the screen, a butt joint will be created. The creation of butt joint will not fail on this model. The shiplap joint properties box will pop up automatically when the butt joint is created.On the ShipLap Joint Properties box, set the values on the boxes to:-Offset value to 2mm because it’s a 4mm shiplap-Depth value to 2.5mm, just high enough that people can see the difference -Angle value to 5 degree so that it looks like in a angleFreeform Mold Demo -11-Ensure the Modify Region icon is selected on the dynabar then click on any two points on the outside curve of the model to define the region of the joint then click on any place on the curve within the region to create the split joint (as shown above).For the demo, create shiplap joint at only one place because for every place you do, you have to be able to select the inside curve of the split joint in the middle of the demo when you are doing Make Part and Make Insert. Therefore, to shorten the demo time and keep the audience’s attention, avoid creating more than one split joint.Next you want to show the Groove split joint feature, make an undo after the shiplap joint is created. Then select Groove Joint icon and the Groove Joint Properties box will appear.Freeform Mold Demo -12-Make sure the sum of the Offset value and the Width value does not exceed the width of the split joint, which is 4mm in this case. Otherwise, you will receive an error message. Once the values are entered, ensure the Create Split Joint icon is selected on the dynabar to create a groove joint on the entire curve. Then select the curve on the screen and a Groove Joint will be created (shown as below)Creating the groove joint for the demo is easier for the Make Part step later in the demo because you don’t have to pick the separate section all the way around the curve.Freeform Mold Demo -13-Freeform Mold Demo -14-Making PartNow I will separate the model into 2 parts, part 1 and part 2. I go to the Make Particon on the toolbar. Then select the Split Curve icon on the dynabar and click on the first split joint then the second split joint of the part. Next I click on the Part 1 Sideicon and click on the outside of the model(the face in this example) to select what is going to the part 1.When selecting the part 1 side, uncheck the Blank Clay to show the whole piece of clay. It’s easier in this way.Freeform Mold Demo -15-The first split joint is the outside curve of the part and the second split joint is the inside curve of the partThe first split joint is highlighted inFreeform Mold Demo -16-The second split joint is highlighted in green as shown on the rightnow look at the other part by selecting Work on Part of the other part in the Object List.Freeform Mold Demo -17-To turn on the object list, either click “o” on the keyboard or go to View > Object listOn the Object List, click on the part icon, and select Work On Part option to select the part that you want to work on.For the rest of the demo, we will work on one part of the model, Part 1 the face, though the other Part 2 can be done in a similar way.Freeform Mold Demo -18-Creating Mold InsertSo the next thing I will create an extent for the part, that is defining the actual mold insert dimensions, and create parting surfaces for the model.The extents can be resized to any dimension you need to fit into the mold. To resize it, you go to the set extents option (which is usually active when first entering the Mold Insert tab) and enter the XYZ values for the extents.To resize the extent, click on Create Mold Insert tab on the top of the workspace thenselect Mold Insert Properties and click on Set Extents icon on the Dynabar. Enter the desired dimension for the extent on the X,Y,Z boxes. For the demo, show people that the extent can be changed and set the numbers in the X,Y,Z boxes to a reasonable numbers. The following numbers are used for this demo:+X = 100.00, -X = -100.00+Y = 150.00, -Y = -150.00Freeform Mold Demo -19-+Z = 100.00, -Z = -100.00Freeform Mold Demo -20-Creating Extruded Parting SurfaceNext I will create the parting surfaces for the part. I go to the Extrude Parting Surfacetool then pick on two places on the curve to define the boundary. When you are picking the points to define the boundary, you don’t have to pick on the points, you can pick anywhere on the curve. The extruded surface can be created in a 45 degree angle. When extruding the surfaces from this example, extrude the surfaces perpendicularly from the form. For example, extrude it in a horizontal or vertical direction.Freeform Mold Demo -21-Creating Insert BlocksAfter the parting surface is completed, I will create a core insert block and a cavity insert blocks for the part. This can be done in a few steps.First I go to the Make Insert Blocks tool on the toolbar. Second, I pick the edge of the parting surface and the parting line. Finally, I select the side for the cavity block. To create insert blocks for the part:-Click on Parting Surface Curve icon on the Dynabar and select the edge of the extruded surface-Then select the parting line of the model (as shown below in green)Freeform Mold Demo -22--Click on Cavity Side icon on the dynabar and select the cavity side of the model.-Once the cavity side is selected, a plane will appear on the screen to represent the bottom of the cavity block.o Notes: Don’t zoom to close to the model; otherwise you will not be able to see the plane.o Notes: If you selected the top part as the cavity side, then the plane should be placed on the topside or on the bottom side if the bottom part isselected as the cavity side.- A window will pop up and asks if the plane is placed correctly, click “Yes” if the plane location is correct or “No” if the plane location is incorrect…Freeform Mold Demo -23-shown below)…Freeform Mold Demo -24-From here, I have two insert blocks, one for the core and the other one for the cavity. I can look at either one of the blocks by selecting it on the Object List.To look at the core block:-Turn on the object list and click on the core mold insert icon, and select Work On Component option-This will hide the cavity side component automatically.Freeform Mold Demo -25-Freeform Mold Demo -26-You can turn off “See Through Clay” option by View > Design Curve > See Through Clay for people easier to see to blockFreeform Mold Demo -27-Reverse Engineering the Core FaceThe next thing I will do is to create patch surface for the core. After I create the patches, I can export the file to other CAD software to build other components on the mold insert such as runners systems, water lines, sprues, and ejection pins, etc. To create the patch, I draw curves that defined the patch boundary on the core. Then using the Patch toolon the toolbar to create the batch surfaces for the core.Freeform Mold Demo -28-To draw curves defining the patch boundary on the core:-Select Draw tool under Parting Line tool-Ensure the Fit on Create icon is selected on the dynabaro Notes: DO NOT select Split on Create icon on the dynabar because it will destroy the surfaces by separating the curve into two-Turn on See Through Clay option by: View > Design Curves > See Through Clay (if you find it to be easier).-Start drawing curve on the model to cover up the entire core (as shown above)Freeform Mold Demo -29-To create patches on the core surface:-Once the curves are drawn on the surface, select the Patch tool-Ensure Fit to Clay and Manual Boundary Select icons are selected on the dynabaro Notes: Selecting the Fit to Clay icon will create patches that are more tightly fitted on the clay surface than using the Fit to Boundary icon . -Click on the curves in sequence to define the boundary of the patch. Once you are done the patches, go to the object list and folder the patches you create and label the folder something meaningful. You will need to refer to this folder later.Freeform Mold Demo -30-Exporting IGESOnce the Core side of Part 1 is patched, it can be exported as an IGES file for further modification in other CAD software.To export an IGES file of the Core side:Go to File > Export > Curves and Patches, then check the following information in the dialog box that appears:Freeform Mold Demo -31-…which will write an IGES file for CAD import. To export an STLfile of each of the blocks of the insert, for rapid prototyping:For the core, turn off the display of all Clay and Curves using the lower left display control:Then go to File > Export > Model, then, it will export the patches which will be subdivided to create polygons out of the patches.Usually, the default has adequate details when exporting the STL polygon file but if you want more detail, go to Patch Display Properties under the Blank Patches icon onFreeform Mold Demo -32-the Dynabar.Freeform Mold Demo -33-Changing the Display Resolution to High in thePatch Display Properties will give you a muchfiner tessellation of the patches.You can verify your results by reading the fileback in as an STL import and preview (but don’tkeep it, just preview it as below…Note: When exporting the Cavity side, you don’t want the Split Joint patches or the core face patches visible. On the Object list, do a “work on component” on the cavity component first, then hide the Split Joint Curves and Split Joint Patches folders as shown on the right. Find the folder you created for the Core face reverse engineering patches and hide it as well.Creating ElectrodeCreating electrode off the cavity is not something that is automatically created but it is not too difficult to do. First you want to turn off the surfaces and build a plane to project the parting line onto the plane. Then draw a line to connect the curves and create a patch for the side. Once the patch is created, export it as an electrode.To Create Electrode Off the Back Cavity Block:Go to the Object list then turn off the surfaces of the core and cavity blocks and the parting surfaces as shown below.Then select New Plane/Sketch on the toolbar to create a plane. The distance between the part and the plane is equal to the distance of the side of the electrode.Select Project Curve to Plane from the flyout of the Parting line curve tool on the toolbar. Then click on the parting line curves and touch the plane. The curves will then be projected onto the plane (as shown below). Once the curve is projected, you can hide the plane on the object list.Freeform Mold Demo -34-Next select Draw from the Parting line curve tool on the toolbar. Make sure the Fit on Create icon on the dynabar is deselected because you want to make a square patch. Then draw a line connected the parting line and the projected parting line.For this model, a patch can be built with only two main curve segments (as shown below)Freeform Mold Demo -35-Freeform Mold Demo -36-dynabar so that a straight extrusion can be created. Then select the curves in sequence to create the patches (as shown below)Once the side patches are created, you can make a patch for the back but for electrodes the back patch is not required. Then export it as an STL file for tooling the electrode.。

stl标准模板库 pdf
stl标准模板库 pdfSTL（Standard Template Library）标准模板库是C++语言中的一个重要组成部分，它提供了许多常用的数据结构和算法，为程序员提供了丰富的工具库，能够大大提高程序的开发效率和代码的重用性。
本文将介绍STL标准模板库的一些基本概念和常用功能，并提供相关的PDF文档供大家参考学习。
STL标准模板库主要包括容器（Containers）、迭代器（Iterators）、算法（Algorithms）三大部分。
其中容器用于存储数据，迭代器用于遍历容器中的数据，算法用于对容器中的数据进行各种操作。
STL的设计思想是将数据结构和算法分离，使得它们能够独立地进行组合和复用，从而大大提高了程序的灵活性和可维护性。
在STL标准模板库中，容器是其中最重要的部分之一。
STL提供了多种类型的容器，包括序列容器（如vector、list、deque）、关联容器（如set、map、multiset、multimap）以及无序关联容器（如unordered_set、unordered_map、unordered_multiset、unordered_multimap）。
每种容器都有其特定的特性和适用场景，程序员可以根据实际需求选择合适的容器来存储数据。
除了容器之外，STL标准模板库还提供了丰富的迭代器，用于遍历容器中的数据。
迭代器可以被看作是一个指向容器中元素的指针，它提供了统一的访问接口，使得程序员可以使用相同的方式来访问不同类型的容器。
STL中的算法通常以迭代器作为参数，通过迭代器来对容器中的数据进行各种操作，如查找、排序、删除、替换等。
在实际开发中，STL标准模板库的算法部分也是非常重要的。
STL提供了大量的算法，包括查找算法（如find、count、equal_range）、排序算法（如sort、partial_sort、nth_element）、修改算法（如copy、replace、swap）、数值算法（如accumulate、inner_product、partial_sum）等。

introduction to finite element methods
introduction to finite elementmethodsFinite element methods (FEM) are numerical techniques used to solve partial differential equations (PDEs) and other mathematical models in engineering and scientific applications. The basic idea behind FEM is to divide a domain into small elements, and then approximate the solution over each element using simple functions. These approximations are then combined to obtain a近似解 for the entire domain.One of the key advantages of FEM is its ability to handle complex geometries and boundary conditions. By dividing the domain into small elements, FEM can accurately represent curved boundaries and irregular shapes. Additionally, FEM can handle a wide variety of boundary conditions, including Dirichlet, Neumann, and Robin boundary conditions.Another advantage of FEM is its flexibility in choosing the type of basis functions used to approximate the solution over each element. Common basis functions include linear, quadratic, and cubic polynomials, as well as Lagrange and Hermite polynomials. The choice of basis functions depends on the nature of the problem and the desired accuracy of the solution.FEM also offers several advantages in terms of computational efficiency. By using matrix-based formulations, FEM can take advantage of modern numerical algorithms and computing hardware to solve large-scale problems efficiently. Additionally, FEM can be easily parallelized, allowing for the efficient use of multiple processors or computing nodes.In summary, finite element methods are powerful numerical techniques that can be used to solve a wide variety of engineering and scientific problems. Their ability to handle complex geometries and boundary conditions, as well as their flexibility in choosing basis functions and computational efficiency, make FEM an attractive choice for many applications.。
freeform拆件方法
freeform拆件方法Freeform 拆件方法是一种常见的3D模型拆件方法，主要用于设计，制造和可视化领域。
它允许设计师将复杂的模型拆分成更简单的部分，以便于后续处理和制造。
本文将讲解Freeform拆件方法的基本原理和具体步骤，以及其在实践中的应用。
Freeform拆件方法的基本原理是将3D模型分解为具有平滑边缘和适当数量的顶点的几何形状。
这样做可以使制造过程更容易和准确，因为简单的形状可以更容易地制作和加工。
此外，拆件过程还可以减少加工时需要的时间和人力成本。
具体步骤如下：1. 导入3D模型首先需要将3D模型导入到拆件软件中，常用的软件有Rhino、SolidWorks和3ds Max 等。
在导入模型之前，需要确定要拆除的部分以及导入时需要设置的单位和比例尺。
2. 选择拆件方法在选择拆件方法之前，需要考虑拆件的目的和要求。
主要有两种拆件方法：面拆件和实体拆件。
面拆件采用表面建模技术，将3D模型拆分为平面形状，适用于需要制造精度高和几何形状规则的产品。
实体拆件则针对复杂的有机形状，使用体积建模技术对3D模型进行切割和分割。
3. 选择切割平面或者切割体在建模软件中实现拆件的过程中，需要先选择一个或多个分解平面或者分解体。
分解平面将形状分解为简单的平面形状，而分解体则将形状分解为简单的几何体。
选择适当的分解方法可以减少后续制造和加工的困难程度。
4. 进行切割操作选择切割平面或切割体后，就可以对模型进行切割操作。
切割操作是将模型沿着选择的平面或体进行割裂，这样就可以将模型分为两个或多个部分。
在进行操作之前，需要设置相应的切割方向、角度和深度等参数，以保证切割效果的精度和符合要求。
5. 优化拆件效果在将模型分解为较简单的形状之后，需要进行优化操作。
这就是对得到的分解形状进行调整、合并、分割等处理，以保证拆件后得到的形状达到预期效果。
优化过程需要人工检查和调整，确保每个部分都符合设计要求。
6. 导出分解部件完成拆件和优化之后，可以将分解后的部件导出，以便于后续的制造、加工和可视化。

三维stl数据拟合原理
三维stl数据拟合原理Three-dimensional STL data fitting is a process of adjusting the shape and dimensions of a 3D model to align with another 3D model or a set of specific measurements. This process is essential in various fields, including manufacturing, engineering, and design. 三维STL数据拟合是一种调整三维模型形状和尺寸以与另一个三维模型或一组特定测量值对齐的过程。
这个过程在制造业、工程和设计等各个领域都是至关重要的。
When it comes to the fitting process, the first step is to analyze the initial STL data and identify the areas that require adjustments. This may involve comparing the model to a reference model or a set of measurements to determine the discrepancies. Following this, the next step is to utilize specialized software to modify the 3D model and achieve the desired fit. 在拟合过程中，第一步是分析初始STL数据并确定需要调整的区域。
这可能涉及将模型与参考模型或一组测量值进行比较，以确定差异。
接下来，利用专业软件修改三维模型，实现期望的拟合。
One of the key techniques used in STL data fitting is the utilization of surface registration algorithms. These algorithms enable the matching of surfaces from two different 3D models and align themto achieve a precise fit. The registration process involves identifying corresponding points on the surfaces, calculating the transformation needed, and applying it to achieve the best fit. STL数据拟合中使用的关键技术之一是表面配准算法。
STL（fileformat）-Wikipedia,thefreeencyclopedia
facet normal n i n j n kouter loopvertex v1x v1y v1zvertex v2x v2y v2zvertex v3x v3y v3zendloopendfacetwhere each n or v is a floating point number in sign-mantissa 'e'-sign-exponent format, e.g., "-2.648000e-002" (noting that each "v" must be non-negative). The file concludes with:endsolid nameThe structure of the format suggests that other possibilities exist (e.g., facets with more than one 'loop', or loops with more than three vertices) but in practice, all facets are simple triangles.White space (spaces, tabs, newlines) may be used anywhere in the file except within numbers or words. The spaces between 'facet' and 'normal' and between 'outer' and 'loop' are required.[2]Binary STLBecause ASCII STL files can become very large, a binary version of STL exists. A binary STL file has an 80 character header (which is generally ignored – but which should never begin with 'solid' because that will lead most software to assume that this is an ASCII STL file). Following the header is a 4 byte unsigned integer indicating the number of triangular facets in the file. Following that is data describing each triangle in turn. The file simply ends after the last triangle.Each triangle is described by twelve 32-bit-floating point numbers: three for the normal and then three for theX/Y/Z coordinate of each vertex – just as with the ASCII version of STL. After the twelve floats there is a two byte unsigned 'short' integer that is the 'attribute byte count' – in the standard format, this should be zero because most software does not understand anything else.[2]Floating point numbers are represented as IEEE floating point numbers and are assumed to be little endian, although this is not stated in documentation.UINT8[80] – HeaderUINT32 – Number of trianglesforeach triangleREAL32[3] – Normal vectorREAL32[3] – Vertex 1REAL32[3] – Vertex 2REAL32[3] – Vertex 3UINT16 – Attribute byte countendColor in binary STLThere are at least two variations on the binary STL format for adding color information:The VisCAM and SolidView software packages use the two 'attribute byte count' bytes at the end ofevery triangle to store a 15 bit RGB color:bit 0 to 4 are the intensity level for blue (0 to 31)bits 5 to 9 are the intensity level for green (0 to 31)bits 10 to 14 are the intensity level for red (0 to 31)bit 15 is 1 if the color is validbit 15 is 0 if the color is not valid (as with normal STL files)The Materialise Magics software does things a little differently. It uses the 80 byte header at the top of the file to represent the overall color of the entire part. If color is used, then somewhere in the header should be the ASCII string "COLOR=" followed by four bytes representing red, green, blue and alpha channel (transparency) in the range 0–255. This is the color of the entire object unless overridden at each facet.Magics also recognizes a material description; a more detailed surface characteristic. Just after"COLOR=RGBA" specification should be another ASCII string ",MATERIAL=" followed by threecolors (3 ! 4 bytes): first is a color of diffuse reflection, second is a color of specular highlight, and third is an ambient light. Material settings are preferred over color. The per-facet color is represented in the two 'attribute byte count' bytes as follows:bit 0 to 4 are the intensity level for red (0 to 31)bits 5 to 9 are the intensity level for green (0 to 31)bits 10 to 14 are the intensity level for blue (0 to 31)bit 15 is 0 if this facet has its own unique colorbit 15 is 1 if the per-object color is to be usedThe red/green/blue ordering within those two bytes is reversed in these two approaches – so while these formats could easily have been compatible the reversal of the order of the colors means that they are not – and worse still, a generic STL file reader cannot automatically distinguish between them. There is also no way to have facets be selectively transparent because there is no per-facet alpha value – although in the context of current rapid prototyping machinery, this is not important.The facet normalIn both ASCII and binary versions of STL, the facet normal should be a unit vector pointing outwards from the solid object. In most software this may be set to (0,0,0) and the software will automatically calculate a normal based on the order of the triangle vertices using the 'right-hand rule'. Some STL loaders (e.g. the STL plugin for Art of Illusion) check that the normal in the file agrees with the normal they calculate using the right-hand rule and warn you when it does not. Other software may ignore the facet normal entirely and use only the right-hand rule. Although it is rare to specify a normal that cannot be calculated using the right-hand rule, in order to be entirely portable, a file should both provide the facet normal and order the vertices appropriately. A notable exception is SolidWorks which uses the normal for shading effects.History of useStereolithography machines are 3D printers that can build any volume shape as a series of slices. Ultimately these machines require a series of closed 2D contours that are filled in with solidified material as the layers are fused together. A natural file format for such a machine would be a series of closed polygons corresponding to different Z-values. However, since it's possible to vary the layer thicknesses for a faster though less precise build, it was easier to define the model to be built as a closed polyhedron that can be sliced at the necessary horizontal levels.The STL file format appears capable of defining a polyhedron with any polygonal facet, but in practice it's only ever used for triangles, which means that much of the syntax of the ASCII protocol is superfluous.To properly form a 3D volume, the surface represented by any STL files must be closed and connected, where every edge is part of exactly two triangles, and not self-intersecting. Since the STL syntax does not enforce this property, it can be ignored for applications where the closedness doesn't matter. The closedness only matters insofar as the software which slices the triangles requires it to ensure that the resulting 2D polygons are closed. Sometimes such software can be written to clean up small discrepancies by moving vertices that are close together so that they coincide. The results are not predictable, but it is often sufficient.Use in other fieldsSTL file format is simple, so it is easy to output. Consequently, many computer-aided design systems can output the STL file format. Although the output is simple to produce, some connectivity information is discarded.Many computer-aided manufacturing systems require triangulated models. STL format is not the most memory and computationally efficient method for transferring this data, but STL is often used to import the triangulated geometry into the CAM system. The format is commonly available, so the CAM system will use it. In order to use the data, the CAM system may have to reconstruct the connectivity.STL can also be used for interchanging data between CAD/CAM systems and computational environments such as Mathematica.NotesIn Windows, the extension .stl is used to mean Certificate Trust List, and a .stl file will be labeled as such, even though it will still be a stereolithography.See alsoAdditive Manufacturing File Format, an ASTM standard that has native support for color, multiplematerials, and constellationsPLY (file format), an alternative file format offering more flexibility than most stereolithographyapplications.Wavefront .obj file, a 3D geometry definition file format with .obj file extensionMeshLab, a free and open source cross-platform application for visualizing, processing and convertingthree-dimensional meshes to or from the STL file format.CloudCompare, another open source application for handling STL files.Mathematica, a technical computing system that can work with STL files.References1. ^ STL2.0 May Replace Old, Limited File Format (/stl-file-format.html).
