Laser cutting is a powerful tool for creating precise, intricate designs across various materials. However, ensuring a successful laser-cut project requires careful preparation of your design file. Whether you’re a beginner or a seasoned designer, following these key steps will help you optimize your file for a smooth and accurate cutting process.
1. Choose the Right File Format
Laser cutters typically work with vector-based file formats. Some of the most commonly accepted formats include:
- DXF (Drawing Exchange Format) – Widely used for technical and mechanical drawings.
- SVG (Scalable Vector Graphics) – Ideal for intricate designs and scalable graphics.
- AI (Adobe Illustrator) – Preferred for detailed graphic work.
- EPS (Encapsulated PostScript) – Useful for compatibility across various design programs.
Using a vector format ensures that the laser cutter follows precise paths instead of pixel-based approximations.
2. Set Correct Line Thickness & Color Coding
Laser cutters distinguish between cutting and engraving based on line thickness and color settings:
- Cut Lines: Use a thin stroke (0.001″ or hairline width) in red.
- Engraving Lines: Set thicker lines (greater than 0.1″) in black or grayscale.
- Etching or Scoring: Use blue to mark shallow cuts without fully cutting through.
Check with your laser cutting provider for specific color coding requirements.
3. Convert Text to Outlines
If your design includes text, convert it to outlines (also known as converting to curves) before exporting. This prevents font substitution issues and ensures that text is treated as a shape rather than an editable font.
In Adobe Illustrator:
- Select your text.
- Click Type > Create Outlines (or press Shift + Ctrl + O).
4. Optimize Your Design for Material Constraints
Different materials respond differently to laser cutting, so consider the following:
- Avoid extremely thin lines – They may break or burn through certain materials.
- Allow for kerf width – The laser removes a small portion of material when cutting, so adjust dimensions accordingly.
- Ensure proper spacing – Leave enough space between cuts to prevent weak spots in the material.
5. Use Closed Paths for Cutting
For accurate cuts, ensure all paths are fully closed (connected). Open paths may result in incomplete or inaccurate cuts.
- Check for gaps in design software by selecting all objects and using the Join or Close Path function.
6. Arrange Parts for Efficient Cutting
To minimize material waste and cutting time:
- Nest parts closely together while maintaining necessary spacing.
- Align parts strategically with the material grain or orientation.
- Use shared cutting lines where possible to reduce redundant cuts.
7. Check and Test Before Final Cutting
Before sending your design to production:
- Run a preview in your software to detect errors.
- Print at scale on paper to verify dimensions and layout.
- Conduct a small test cut if possible to ensure accuracy.
