Learn to Use the Laser Cutter Safely

Perfect for makers, small businesses, and creative experiments.

Our laser cutter can precisely cut and engrave wood, acrylic, cardboard, leather, and more. This guide explains what to expect from your first training, how to prepare files, and how to run a safe laser job at Kalamazoo Makerspace.

What You Can Make

  • Custom signs and wall art – Engrave logos, text, and illustrations.
  • Prototype enclosures – Cut panels and parts for electronics projects.
  • Jigs and fixtures – Make helpers for woodworking and metal projects.
  • Personalized gifts – Engraved cutting boards, keychains, and ornaments.
  • Inlays and decoration – Combine laser-cut parts with woodworking, metal, or 3D prints.
  • Educational projects – Classroom kits, puzzles, and STEM demonstrations.

Laser Cutter Basics

Before you run your first job, you’ll complete a hands-on orientation. You’ll learn:

  • How to power on the laser, exhaust, and air assist.
  • How to focus the lens and position your material.
  • Which materials are safe (and unsafe) to cut.
  • How to choose speed and power settings.
  • How to send jobs from design software to the laser.
  • What to watch and smell for while the laser is running.

After you are signed off, you can use the laser independently during staffed hours, following our posted safety rules.

From Idea to Finished Part: Step-by-Step

  1. Bring an idea or sketch. Even a rough drawing helps us suggest materials and design approaches.
  2. Choose a material. Start with small pieces of plywood, MDF, cardboard, or cast acrylic from the approved list.
  3. Prepare your design file. We recommend vector files (SVG, DXF, PDF) for cutting and high-contrast images for engraving.
  4. Set up the laser. Turn on exhaust and air assist, place your material, and focus using the provided gauge.
  5. Frame and test. Use the machine controls or software to outline the job area and run a small test cut or engrave.
  6. Run the job while watching it. Never leave the laser unattended. Keep the lid closed and be ready to pause or stop.
  7. Inspect and clean up. Check your part, adjust settings if needed, then remove scraps and leave the area ready for the next member.

Laser Safety & Approved Materials

Safety Rules You Must Follow

  • Never leave the laser unattended while it is cutting or engraving.
  • Keep the lid closed anytime the laser is active.
  • Turn on exhaust and air assist before starting a job.
  • Keep a clear work area around the machine and avoid stacking materials in the bed.
  • Know the emergency stop and how to quickly shut down the machine.
  • Stop immediately if you see sustained flames or smell something unusual.
  • Wear safety glasses if recommended by the trainer for specific tasks.

Typical Laser-Safe Materials

Always confirm with the posted signage or your trainer. When in doubt, do not cut it until it has been approved.

  • Birch or craft plywood (no exterior or pressure-treated lumber).
  • Uncoated MDF and hardboard.
  • Cardboard and chipboard.
  • Paper and card stock.
  • Cast acrylic (PMMA) – not polycarbonate.
  • Natural leather and some fabrics.

Never cut: PVC, vinyl, unknown plastics, reflective metals, or anything that may release chlorine or heavy-metal fumes.

Laser Cutter FAQ

Do I need training before I can use the laser cutter?

Yes. All new users must complete a laser orientation or class with an approved trainer. This ensures you understand safety rules, basic operation, and our makerspace policies.

What software can I use for laser cutting?

You can create designs in Inkscape, Adobe Illustrator, CorelDRAW, LightBurn, or similar software. We typically accept SVG, DXF, PDF, and standard image formats like PNG or JPG for engraving.

Can I bring my own materials?

Yes, as long as they are on our approved list and clearly labeled. If you are unsure about a material, ask a volunteer or trainer before cutting. Unlabeled plastic is treated as unsafe.

How much does it cost to use the laser?

Access to the laser is included with the appropriate membership level. You are responsible for your own materials. For the latest pricing and membership options, visit our membership page.

Can I sell products made on the laser?

Many members use the laser to prototype or produce items for craft shows, Etsy shops, and small businesses. As long as you follow our usage policies and respect other members’ time, you can absolutely build your side hustle here.
