How to Use SolidWorks for 3D Printing: Step-by-Step Guide

To use SolidWorks for 3D printing, first design your 3D model using SolidWorks tools, then export the model as an STL file. This file can be imported into 3D printing software to prepare and print your object.

Syntax

In SolidWorks, the key steps to prepare a model for 3D printing involve designing the part, checking its geometry, and exporting it as an STL file.

• Design Model: Use SolidWorks features to create your 3D shape.
• Check Geometry: Ensure the model is solid and has no errors.
• Export STL: Save the model as an STL file for 3D printing.

3d_printing

File > Save As > Select 'STL (*.stl)' from file type dropdown > Click 'Options' to set resolution > Save

Example

This example shows how to export a simple cube model from SolidWorks as an STL file ready for 3D printing.

3d_printing

1. Open SolidWorks and create a new part.
2. Use the 'Extruded Boss/Base' feature to create a 20mm x 20mm x 20mm cube.
3. Click 'File' > 'Save As'.
4. Choose 'STL (*.stl)' as the file type.
5. Click 'Options' and set the resolution to 'Fine' for better print quality.
6. Save the file to your computer.
7. Import the STL file into your 3D printer software to slice and print.

Output

STL file of a 20mm cube saved and ready for 3D printing.

Common Pitfalls

Common mistakes when using SolidWorks for 3D printing include:

• Exporting the model with incorrect units, causing size issues in printing.
• Not checking for gaps or holes in the model, which can cause print failures.
• Using low STL resolution, resulting in rough or inaccurate prints.
• Forgetting to make the model a solid body; surfaces alone cannot be printed.

Always verify your model's integrity and export settings before printing.

3d_printing

Wrong way:
File > Save As > Choose STL > Save (without checking units or resolution)

Right way:
File > Save As > Choose STL > Click Options > Set correct units (mm) and resolution (Fine) > Save

Quick Reference

Step	Action	Tip
1	Design your 3D model	Use solid features and ensure it is a closed solid body
2	Check model units	Set units to millimeters for most 3D printers
3	Export as STL	Use 'Fine' resolution for better print quality
4	Import STL to slicer	Prepare print settings like layer height and supports
5	Print	Use your 3D printer software to start printing

Key Takeaways

Always export your SolidWorks model as an STL file with correct units and high resolution.

Ensure your model is a solid body without gaps or holes before exporting.

Use the 'Save As' > 'STL' option and adjust export settings for best print quality.

Check your model in 3D printing software before printing to avoid errors.

Design with 3D printing constraints in mind, like wall thickness and support needs.
