Export to STL

Export to STL

Our little guide to export from your CAD application to STL. If you cannot find your chosen application, let us know and we will try and  add it on for you.

form – Z/bonzi3D

File > Export > STL


  1. Click Output tab > Send panel > Export
  2. In the Export Data dialog box, enter a file name.
  3. Under Files of type, select Lithography (*.stl). Click Save.
  4. Select one or more solid objects. All objects must be entirely within the positive XYZ octant of the world coordinate system (WCS). That is, their X, Y, and Zcoordinates must be greater than zero.
  5. The file extension .stl is automatically appended to the file name.


Part > Export Part > as STL


  1. Select “File -> Export -> Save As … -> STL”
  2. Enter file name
  3. Press Save.


All models exporting should be 3D body, instead of just being surface, and all the XYZ coordinates should be positive values.


  1. Enter command “Facetres” in command line.
  2. Set FACETRES as a value from 1 to 10 (1 is for low resolution, and 10 is for high resolution)
  3. Enter command “STLOUT” in command line.
  4. Choose model to export
  5. Select Y, and output as binary file.
  6. Enter filename


  1. Select “File > Export > Rapid Prototype File > OK”
  2. Select the model to export
  3. Select Prototype Device > SLA500.dat > OK
  4. Set absolute facet deviation as 0.000395
  5. Select Binary > OK


  1. Click right mouse button to a model to export
  2. Select “Part Properties > Rendering”
  3. Set Facet Surface Smoothing as 150
  4. Select “File > Export”
  5. Select .STL

Mechanical Desktop:

User command “AMSTLOUT” to export STL file.

To output the STL file, the following parameters on the command line affects the quality of the STL output.

  1. Angular Tolerance: Set maximum angles between two adjacent triangles. The default value is 15 degrees, and lower value of this parameter can increase the resolution of STL.
  2. Aspect Ratio: Set ratio between height and width for triangle. 1 would mean the height of a triangle is less than width, and 0 is default value, which is ignored.
  3. Surface Tolerance: This value is for the maximum deviation between edge of a facet and the actual value. If it is set as 0.0000, this parameter is ignored.
  4. Vertex Spacing: This value is for the length of the edge of a facet. The default value is 0.0000, ignored.


  1. Select “File > Export > Model” or select “File -> Save a Copy”
  2. Set the file type as STL
  3. Set chord height as 0, which will be treated as the minimum value the system accepts.
  4. Set Angle Control as 1
  5. Select a file name

ProE Wildfire:

  1. Select “File -> Save a Copy -> Model”
  2. Set file type as STL(*.stl)
  3. Set chord height as 0, which will be treated as the minimum value the system accepts.
  4. Set Angle Control as 1


  1. Select “File -> Save As”
  2. Select File Type as “STL”
  3. Enter the file name
  4. Select Save
  5. Select Binary STL files.
