The field will be replaced by minimum acceptable value. Vertex Spacing - This option controls the length of the edge of a facet.A setting of 0.0000 causes this option to be ignored. Surface Tolerance - This setting controls the greatest distance between the edge of a facet and the actual geometry.A setting of 1 would mean the height of a facet is no greater than its width. Aspect Ratio - This setting controls the Height/Width ratio of the facets.Reducing the angle will increase the resolution of the STL file. Angular Tolerance - This command limits the angle between the normals of adjacent triangles.The following command line options affect the quality of the STL and should be adjusted to produce an acceptable file.Use the AMSTLOUT command to export your STL file.Set absolute facet deviation to 0.000395.Select Prototype Device >SLA500.dat >OK.Choose Stereolithography from Export options.Make sure the model is in positive space.Your design must be a three-dimensional solid object to output an STL file.Should Quickparts determine that your STL file is not adequate for production, we will contact you for an updated file.)
Please consult your users guide or the software's developers for more information or technical support. (Please note, these are only general guidelines and may not work or produce the best possible STL file in some cases. An exception is the High Resolution SLA, which will make features down to 0.010 and the SLS Flex material, which needs 0.040 thickness to produce features. Please check your models and make appropriate changes to critical features. Anything less then this and features will not develop. For many geometries, files larger then 5MB are unnecessary and will often just result in more time to get your quote and parts back.Īlso, for most RP processes and materials, the minimum feature thickness is 0.020. For complex models, files sizes in the range of 1-5MB will produce good parts. For simple geometry (not a lot of curves), the file may only be a couple hundred kilobytes. The larger the STL file, the more triangles placed on the surface of the model. This saves on time and file size.Īs a general rule, changing options such as Chord Tolerance or Angular Control will change the resolution on your STL file. In all cases, export your STL file as a Binary file. Below are steps for producing high quality STL files from a number of today's leading CAD systems. For the user the process is often as simple as selecting File, Save As, and STL. Almost all of today's CAD systems are capable of producing an STL file.
