Cutting 10mm Acrylic Perfectly: CO2 Laser Settings & Machine Picks
Acrylic, also known as polymethyl methacrylate (PMMA), is a versatile and widely used material in signage, displays, lighting, and decorative applications. Its clarity, durability, and ease of processing make it ideal for laser cutting — especially with CO₂ laser machines.
However, achieving a clean, polished edge when cutting 10mm thick acrylic requires precise settings and the right equipment. In this article, we’ll walk through the optimal CO₂ laser settings for cutting 10mm acrylic and recommend some top-performing laser machines that deliver excellent results.
Why Use a CO₂ Laser for Acrylic?
CO₂ lasers are the most suitable type for cutting acrylic due to their wavelength (around 10.6 µm), which is highly absorbed by organic materials like plastics. This leads to efficient, clean cuts with minimal charring or melting. When properly configured, a CO₂ laser can produce flame-polished edges on acrylic — a major advantage over mechanical cutting methods.
Key Factors for Cutting 10mm Acrylic
Before diving into specific settings, here are the key factors that influence the quality of your cut:
Laser Power: Higher power allows for faster and cleaner cuts through thicker materials.
Air Assist: Blows away molten material and prevents re-adhesion, reducing smoke marks.
Focus Position: The focal point should be at or slightly below the surface of the material for maximum efficiency.
Ventilation: Proper exhaust removes harmful fumes and maintains lens clarity.
Material Quality: High-grade acrylics yield better results than recycled or low-quality sheets.
Recommended CO₂ Laser Settings for 10mm Acrylic
While exact parameters may vary depending on your machine and acrylic brand, here’s a general starting point:
Parameter
Setting
Power (%)
85–100%
Speed (mm/min)
300–600 mm/min
Frequency (kHz)
10–20 kHz
Air Assist
On (High Pressure)
Focus Height
At material surface
💡 Tips for Best Results:
Do a test cut on a scrap piece before working on your final design.
Reduce speed if you notice uncut sections or excessive melting.
Increase frequency for smoother edges.
Always use a honeycomb bed or elevated platform to prevent backside melting.
