Acrylic sheet, also known as PMMA (Polymethyl Methacrylate) or plexiglass, is one of the most versatile materials in modern manufacturing. It combines optical clarity, lightweight strength, and excellent machinability, making it ideal for lighting, signage, display, and architectural applications.
Among all cutting methods, laser cutting is widely regarded as the most precise and professional way to shape acrylic.
So, can you laser cut acrylic sheet?
The answer is absolutely yes—laser cutting is the preferred technique for producing clean, polished edges and complex shapes without the need for mechanical finishing.
At KUNXIN Plastics, we specialize in laser-cut acrylic sheet fabrication, providing OEM/ODM services for global clients who require precision and aesthetics in every project.
Laser cutting uses a concentrated CO₂ laser beam to vaporize material along a programmed path. Because acrylic absorbs the laser wavelength efficiently, it produces a crisp, flame-polished edge with high dimensional accuracy.
Extremely Smooth Edges – No burrs or post-polishing needed.
High Precision – Cutting accuracy within ±0.1 mm.
Complex Shapes Possible – Ideal for curves, lettering, and patterns.
No Physical Contact – Eliminates cracking or vibration damage.
Fast Production – Automated and repeatable for high-volume manufacturing.
Laser cutting has become the go-to method for optical and decorative acrylic fabrication, ensuring consistent quality from prototype to mass production.
Not all plastics respond the same to lasers, but both main types of acrylic perform exceptionally well.
| Type | Characteristics | Laser Cutting Result |
|---|---|---|
| Cast Acrylic Sheet | Harder, excellent optical clarity | Produces flame-polished edges, ideal for displays and signage |
| Extruded Acrylic Sheet | Softer, more cost-efficient | Cuts cleanly but with slightly frosted edges |
KUNXIN Plastics supplies both cast and extruded acrylic sheets, available in clear, frosted, colored, mirrored, and textured finishes, all suitable for precision laser fabrication.
The process involves three key stages:
Digital Design Setup
A CAD or vector file (.dxf, .ai, .svg) defines the cutting pattern.
This enables intricate shapes such as brand logos, letters, and optical lenses.
Laser Beam Interaction
The CO₂ laser beam (usually 10.6 μm wavelength) melts and vaporizes acrylic precisely along the programmed path.
The energy is concentrated in a small area, creating smooth edges without tool marks.
Cooling and Finishing
A compressed air assist removes fumes and prevents overheating.
After cutting, no polishing or sanding is needed—the edge appears glossy and transparent.
| Parameter | Typical Setting | Purpose |
|---|---|---|
| Laser Power | 60–150 W | Determines cutting depth |
| Cutting Speed | 10–30 mm/s | Balances heat and smoothness |
| Air Assist | Low to medium | Prevents flame and discoloration |
| Focus Distance | Adjusted per thickness | Ensures edge precision |
| Maximum Thickness | Up to 25 mm | Depends on power and quality |
These settings may vary based on acrylic grade and thickness.
At KUNXIN Plastics, our technicians calibrate each cutting parameter to guarantee clean edges and optical-grade transparency.
Laser cutting delivers superior quality compared with manual or saw cutting.
| Feature | Laser Cutting | Mechanical Cutting |
|---|---|---|
| Edge Finish | Glossy, flame-polished | Matte, requires polishing |
| Precision | ±0.1 mm | ±0.5 mm |
| Complex Shapes | Excellent | Limited |
| Heat Distortion | Minimal | Higher |
| Repeatability | Perfectly consistent | Depends on operator skill |
| Production Speed | High | Medium to low |
This precision is particularly valuable for architectural lighting diffusers, custom signage, and decorative wall panels, where every edge must meet aesthetic and functional standards.
Laser cutting is a clean and safe method when performed with proper setup and materials.
Use Only Pure PMMA – Avoid PVC or ABS, which emit harmful fumes.
Keep Protective Film On – Reduces surface scratches and soot buildup.
Ensure Ventilation – Extract fumes and residues during operation.
Avoid Excessive Power – Overheating can cause discoloration.
Store Sheets Flat Before Cutting – Prevents warping and uneven edges.
KUNXIN Plastics uses professional-grade laser cutting machines with enclosed chambers and fume extraction to ensure both safety and precision.
Laser-cut acrylic products are used across numerous industries due to their clarity, strength, and premium appearance:
Illuminated Signage and Lettering
Architectural Lighting Panels and Diffusers
Decorative Wall and Ceiling Panels
Retail Display Fixtures and Product Stands
Protective Covers and Instrument Panels
Custom Branding and Art Installations
Every design benefits from acrylic’s light transmission of 92–93% and smooth polished edges achievable only through laser processing.
At KUNXIN Plastics, we operate advanced CO₂ laser cutting and CNC fabrication lines in Jiangmen, Guangdong.
Our services include:
Custom Cutting: Clear, frosted, colored, mirrored, and patterned acrylic.
Engraving & Etching: Branding, labeling, or decorative surface textures.
Edge Finishing: Optical-grade flame polishing and deburring.
OEM/ODM Projects: Tailored solutions for lighting, display, and design clients.
Fast Lead Time: Streamlined production for international orders.
Our technical expertise ensures each sheet meets optical, dimensional, and aesthetic requirements demanded by professional buyers.
Q1: Does laser cutting cause acrylic to melt?
No, when properly adjusted. The laser vaporizes rather than melts, leaving clean edges.
Q2: Can colored acrylic be laser cut?
Yes. Transparent, translucent, and opaque acrylic sheets all respond well to CO₂ laser cutting.
Q3: What is the thickest acrylic that can be laser cut?
Up to 25 mm, depending on machine power and optical focus.
Q4: Does laser cutting discolor the edges?
Not with pure PMMA. KUNXIN’s sheets produce crystal-clear polished edges without burning.
Q5: Do you offer custom designs or pre-cut panels?
Yes. We accept CAD drawings and design files, offering full OEM/ODM support for international customers.
