How to Use DXF Files for Laser Cutting

DXF files are one of the most popular formats for laser cutting and CNC machines.
If you’ve downloaded a DXF file and don’t know what to do next — here’s the simple process.

1️⃣ Import the DXF file

Open your laser software (LightBurn, RDWorks, xTool, Glowforge, etc.)
Click Import and select your DXF file.

If the design appears as vector lines — you’re good.

2️⃣ Check the design

Before cutting, always:

✔ Make sure lines are closed
✔ Remove duplicate paths
✔ Confirm correct size (mm or inches)

Clean DXF files save material and time.

3️⃣ Set cutting parameters

Adjust:

• Power
• Speed
• Material thickness

Example for 3mm plywood:

• 60–70% power
• 15–20 mm/s

Always test on a small piece first.

4️⃣ Start cutting

Frame the design, secure the material, and start the job.

If the DXF file is properly optimized, the cut should be smooth and precise.

DXF vs SVG for Laser Cutting

• DXF → Best for CNC and industrial laser machines
• SVG → Often used for Cricut and craft cutting

Most professional laser files include both formats.

Final Tip

Always use ready-to-cut DXF files designed specifically for laser and CNC machines. Poor files cause double lines, open paths and machine errors.
