Introduction: COVID-19 Laser Cut Face Mask

About: Hi. My name is Adelle and I work for Trotec Laser, Inc. In my spare time I enjoy sharing projects for people to use on their lasers.

The attached laser tutorial video will give you the information on how to create a protective face mask using your laser and sewing machine. If we make our own masks, it will help ease the shortage to hospitals, and reserve the supply of N95 and medical-grade masks for those on the front lines.


  • CO2 laser cutter (We used a Trotec Speedy 360 80W with a 2" lens)
  • Cotton fabric (fabric can be found online at various craft stores)*
  • Cotton rope (rubber band/elastic would work well too)

*Please keep in mind when choosing fabric that it is recommenced for a face covering use.

Step 1: Process the Fabric

Position a sheet of standard cotton fabric into the laser machine. Pick a mask size for the three standard options, and laser-cut the materials using the file provide. You can cut one, or an array of samples, as shown in the video. Once processing has completed, remove the remaining material from your samples. Repeat this process with another sheet of cotton material.

Tip: Use two different colored fabrics, so that it is easy to determine which sides face towards and away form the mouth.

Laser Parameters*

  • Color: Red
  • Process: Cut
  • Power (%): 100.00
  • Speed (%): 5.00
  • ppi/Hz: 5000ppi

*Use these parameters as a guide but make sure you adjust your settings if you have a different machine or wattage.

Step 2: Sew Inner and Outer Mask Sides

Start by pinning two pieces of each color together. Sew them together, as demonstrated in the attached video. Repeat for the other color. Determine which color will be your inner and outer-facing sides of your mask.

Step 3: Assemble Your Mask

Fit the inner and outer-facing fabrics together. Place the cording in the appropriate spots, and then pin the cords in place. Proceed to sew each of the sides of the mask.
