Mastering Laser Cutter Settings for Different Materials: A Comprehensive Guide
Laser cutting has become an essential tool in modern manufacturing, design, and crafting. Whether you’re working with wood, metal, acrylic, or glass, understanding the right laser cutter settings is crucial to achieving precision and optimal results. This guide will walk you through the ideal settings for various materials, ensuring your projects turn out exactly as envisioned.
Introduction to Laser Cutter Settings
Before diving into specific materials, it’s important to understand the basics of laser cutter settings. The three primary parameters are power, speed, and focus. Adjusting these settings correctly can mean the difference between a polished finish and a botched project. For detailed guidance, refer to our comprehensive guide on laser cutter settings for different materials.

Laser Cutter Settings for Wood
Wood is one of the most popular materials for laser cutting due to its versatility and natural aesthetic. However, different types of wood require varying settings:
- Hardwoods: Set the power between 50-70% and speed at 100-200 mm/s. Ensure the laser is focused properly to avoid burning.
- Plywood: Use a slightly lower power of 40-60% with speeds around 80-150 mm/s to prevent splintering.
- Basswood: Opt for a medium setting with power at 40-50% and speed between 120-180 mm/s.
Tip: Always start with lower settings and gradually increase to avoid damage. Test cuts on scrap material are highly recommended.
Laser Cutter Settings for Metal
Metal laser cutting requires precision and the right equipment, such as a laser cutter designed for metal. Here are some key settings:
- Steel: Use high power (80-100%) with moderate speeds (200-300 mm/s). A focused beam is essential to ensure clean cuts.
- Aluminum: Set the power slightly lower at 60-80% and increase speed to 250-400 mm/s. Be cautious of heat buildup, which can cause warping.
- Copper: Due to its high reflectivity, use a red laser with reduced power (30-50%) and slower speeds (80-120 mm/s).

Laser Cutter Settings for Acrylic
Acrylic is a favorite among crafters and designers due to its smooth finish and wide range of colors. Here’s how to set your laser cutter for acrylic:
- Thin Acrylic (1-3mm): Use moderate power (40-60%) with high speeds (250-400 mm/s) to avoid melting.
- Thick Acrylic (5-10mm): Increase power to 60-80% and reduce speed to 150-300 mm/s for cleaner cuts.
- Tip: Always cut on a bed of protective material like MDF or glass to prevent burn marks on the underside.
Laser Cutter Settings for Glass
Glass is a challenging but rewarding material for laser cutting. Here’s how to achieve success:
- Fused Glass: Use low power (20-40%) with slow speeds (60-100 mm/s). Multiple passes may be necessary to create deep scores.
- Laminated Glass: Set the power slightly higher at 30-50% and increase speed to 80-150 mm/s. Always wear safety goggles and ensure proper ventilation.

Troubleshooting Common Issues
Encountering problems like burns, uneven cuts, or warping? Here are some solutions:
- Burn Marks: Lower the power and increase speed. Ensure the material is properly secured to avoid movement during cutting.
- Uneven Cuts: Check for lens fouling or misalignment. Clean the lens and adjust the focus as needed.
- Warping: Avoid prolonged exposure by reducing power and increasing speed. Use a cooling system if available.
