Como generar .stl desde tu Programa CAD favorito

Para poder imprimir un modelo en una impresora 3D es necesario generar antes el archivo STL correspondiente. STL (de estereolitografía) es un formato de archivo que prácticamente todos los programas de control de impresoras 3D aceptan.


Muchos, sin embargo, hemos tenido problemas a la hora de generar estos archivos partiendo de nuestro diseño y luego, al imprimirlos en 3D, el resultado no ha sido el deseado.

La siguiente guía debería ayudaros a resolver estos problemas y obtener ficheros STL perfectos, listos para enviar a vuestra impresora 3D.


Archivo STL: El paso previo a la Impresion 3D

A continuación, los pasos necesarios para exportar un .STL:

SolidWorks
  • File > Save As

  • Set Save As Type to STL

  • Options > Fine > OK

  • Save

  • STL settings: How to change STL settings

  • File > Save As

  • STL > Options

  • For a smoother STL file, change the Resolution to Custom

  • Change the deviation to 0.0005in (0.004 mm)

  • Change the angle to 5 (Smaller deviations and angles will produce a smoother file, but the file size will get larger)

  • Pro/ENGINEER

  • File > Export > Model

  • STL

  • Set chord height to 0. The field will be replaced by minimum acceptable value.

  • Set Angle Control to 1

  • OK

IronCAD
  • Richt Click on the part

  • Part properties > Rendering

  • Set Facet Surface smoothing to 150

  • File > Export

  • Choose .STL

Solid Edge
  • Open Model & select File > Save As

  • Select File type as STL

  • Options > conversion tolerance to 0.015 mm

  • Surface Plane Angle > 45°

  • Select Binary type and OK

  • Name & Save STL file

AutoDesk Inventor
  • Go to the File menu, then select the ‘Save Copy As’ option

  • Select STL from the Types drop-down

  • Click the Options button, and choose the High detail level

  • Click the Save Button

3D Studio MAX 3D
  • File > Export>

  • Select "StereoLitho [*.STL]" in 

  • Select location

  • Enter a name

  • Save

  • OK

  • Export To STL dialog

  • Object Name: Enter a name for the object you want to save in STL format.

  • Binary/ASCII: Choose whether the STL output file will be binary or ASCII (character) data. ASCII STL files are much larger than binary STL files.

  • Selected Only: Exports only objects that you selected in the 3D Studio scene.

Rhinoceros 5.0
  • File > Export Selected>

  • Select [*.STL]" in 

  • Tolerancia: 0,01 mm

  • Ok

Autodesk Fusion 360
  • Seleccionar componente o modelo

  • "MAKE" o Save as STL

  • Guardar como STL

AutoCAD
  • Set DISPSILH to 1

  • Set ISOLINES to 0

  • Set FACETRES to 10

  • Relocate the object to the positive X-Y-Z octant

  • Use the STLOUT command to export a .stl file. (AMSTLOUT for AutoCAD Desktop files)

Blender
  • File> Export > STL

  • Enter Filename

  • Select Location

  • Click button Export STL

CAD Key
  • File > Export > STL

  • Type in a filename and select OK

  • Change Format to Binary

  • Use default Facet Tolerance

  • Additional export tolerance options are in the Solids99 Configuration window accessed from the Tolerance section of Configuration.

Catia

  • Select the entire product tree

  • Tools >Generate CATPart from product

  • Enter a new part number or name

  • Do NOT check: merge all bodies of each part in one body

  • OKYou will now be able to export the CATPart in the Part Design EnvironmentThe accuracy of the .stl file is a fuction of the Display accuracy.

  • Tools > Options...

  • In the tree select General > Display

  • Select the Performance tab

  • Under 3D accuracy, select Fixed

  • Set to .02mm (.0008in)

  • Adjust Curve accuracy ration to .2

  • OK

  • File > Save As

  • Enter filename

  • Select type STL

  • Save

Inventor
  • File > Save as > Save Copy as…

  • Select STL

  • Enter Filename

  • Click the Options button

  • Format Binary

  • Select units

  • Resolution > medium or high

  • Click the Save button

Iron CAD
  • Select Part Properties then Rendering

  • Set Facet Surface Smoothing to 150

  • Select File then Export

  • Select .STL

Mechanical Desktop
  • Use the AMSTLOUT command to export your STL file.

  • The following command line options affect the quality of the STL and should be adjusted to produce an acceptable file.

  • Angular Tolerance - This command limits the angle between the normals of adjacent triangles. The default setting is 15 degrees. Reducing the angle will increase the resolution of the STL file.

  • Aspect Ratio - This setting controls the Height/Width ratio of the facets. A setting of 1 would mean the height of a facet is no greater than its width. The default setting is 0, ignored.

  • Surface Tolerance - This setting controls the greatest distance between the edge of a facet and the actual geometry. A setting of 0.0000 causes this option to be ignored.

  • Vertex Spacing - This option controls the length of the edge of a facet. The

  • Default setting is 0.0000, ignored

Pro Engineer
  • File > Export > Model

  • STL

  • Set chord height to 0. The field will be replaced by minimum acceptable value.

  • Set Angle Control to 1

  • OK

Revit

Revit does not allow direct export to STL files but does allow to first save as .dwg file and open in AutoCAD to create .stl files.

  • 3D view

  • File menu > Export CAD format > select 3D polymesh

  • Save as Type > AutoCAD 2004 DWG

Think 3
  • File > Save As

  • Set Save As Type to STL
