How Do I Make SketchUp 3D Printable?

SketchUp is a powerful 3D modeling tool that allows users to create and modify 3D designs. While SketchUp is primarily used for architectural and product design, you may sometimes find the need to convert your SketchUp models into a format that can be 3D printed. In this tutorial, I will guide you through the process of making your SketchUp models ready for 3D printing.

Step 1: Check and Fix Your Model

Before you can start preparing your SketchUp model for 3D printing, it’s important to ensure that it is watertight and free from any errors or issues that could cause problems during the printing process.

  • Check for Holes: Holes in your model can lead to printing errors. To check for holes, go to Extensions > Solid Inspector.

    This handy tool will analyze your model and highlight any problem areas.

  • Fixing Holes: If Solid Inspector identifies any holes, use the Eraser tool to delete unnecessary edges or faces that are causing the holes. Then use the Line tool or Arc tool to create new edges or faces to patch up the holes.
  • Cleanup Geometry: It’s important to make sure your model has clean geometry with no overlapping faces or stray edges. Use the Eraser tool or the Intersect Faces feature (right-click on a group or component) to remove any overlapping geometry.

Step 2: Scale Your Model

The next step is to scale your model appropriately for 3D printing. Most 3D printers require models to be within a specific size range. To scale your model in SketchUp:

  1. Select the Entire Model: Use the Select tool to select all the geometry in your model.
  2. Scale Tool: Go to Edit > Scale or use the shortcut ‘S’ to activate the Scale tool.
  3. Scale Uniformly: While holding down the Shift key, click and drag one of the corner handles of the bounding box to scale your model uniformly. You can also type in precise dimensions in the VCB (Value Control Box) at the bottom-right corner of SketchUp.

Step 3: Export as STL

The final step is to export your SketchUp model as an STL file, which is a commonly used file format for 3D printing.

  1. Select Your Model: Use the Select tool to select your entire model.
  2. Export as STL: Go to File > Export > 3D Model. Choose a location on your computer and give your file a name.

    In the “Save as type” drop-down menu, select “STL (*.stl)” as the file format. Click on “Options” to set additional export settings if needed.

  3. Set Units: In the “STL Export Options” dialog box, make sure that “Binary” is selected for “Export Type” and choose appropriate units for your model’s size.
  4. Export: Click on “OK” to export your SketchUp model as an STL file ready for 3D printing!

In Conclusion

Making a SketchUp model 3D printable involves checking and fixing any errors, scaling it appropriately, and exporting it as an STL file. By following these steps, you can ensure that your SketchUp creations are ready to be brought to life through 3D printing!
