How Does Laser Cutting and Engraving Plastic Work?
Laser cutting and engraving machines work by generating a laser beam to heat up the material to the point of vaporization or melting, creating a cut or an engraved mark.
The laser beam can be modulated in power, speed, and frequency to achieve different effects and depths. It moves along a predefined path controlled by laser cutter software, allowing for complex and precise shapes and patterns.
The difference between laser cutting plastic and laser engraving plastic is the depth of cut and the amount of material removed by the laser beam. Laser cutting removes material completely along the cut line, creating a separation in the material. Laser engraving removes partial material from the surface, creating a depression or a contrast.

What is the Best Plastic for Laser Cutting and Engraving?
Before you start laser cutting and engraving plastic, you need to be aware of the appropriate type, as some plastics release toxic gases when exposed to laser.
What Plastics Can Be Laser Cut?
Some of the common plastics you can cut and engrave using a laser cutter and engraver are,
- Polymethyl methacrylate (PPMA)(Acrylic)
- Delrin
- Mylar
- Polyimide
- Polyester
- Polyurethane
- Polyethylene terephthalate (PET)
Even though these plastics are safe for laser processing, you need to make sure the ventilation is proper and there are complete safety considerations.

Polyvinyl chloride (PVC) is a very common plastic, and it is used in a wide range of essential and daily used products. But you cannot cut it using a laser machine as it produces harmful smoke of hydrochloric acid, vinyl chloride, ethylene dichloride, and dioxin. All these vapors and fumes are corrosive, toxic, and carcinogenic, so your health will be at risk if you process them using your laser machine.
What Type of Laser Cutter Can Cut Plastic?
When it comes to laser cutting and engraving plastics, the type of laser you choose plays a crucial role. Here's a breakdown of the most common types of lasers and their suitability for plastic:
CO2 Laser Cutters
These are the workhorses for plastic fabrication. Their wavelength is perfectly suited for efficiently cutting and engraving a wide variety of plastics. They deliver clean cuts and precise engravings on most plastics. For best results, consider a CO2 laser cutter with at least 40 watts of power.
Diode Laser Cutters
Diode laser cutters(455nm) offer a more affordable entry point, but their capabilities for cutting plastic are limited. They typically lack the power to completely cut through most plastics. And because of their wavelength, they can only cut and engrave opaque plastic. If your project involves mostly engraving or working with thin plastics, a diode laser may be sufficient.
Infrared Laser Engravers
Similar to CO2 lasers, infrared lasers(1064nm) are also excellent choices for engraving plastics. They create sharp, high-quality engravings on a broad range of plastic materials.
Best Laser Cutter for Plastic
For plastic laser cutting, you need a powerful laser that can easily cut plastic fast. Therefore, a CO2 laser cutter like xTool P2 is the best option.
It can cut and engrave a wide range of materials, including plastic, wood, rubber, leather, paper, fabric, etc.
You can easily cut acrylic of any color, including transparent acrylic. Other than that, it can cut other plastics that are suitable for laser cutting.
Its superior power (55W) allows it to cut 18mm black walnut or 20mm acrylic in a single pass. Coupled with a built-in air assist and fan, the xTool P2 ensures fast, clean cuts without burnt edges or smoke residue.
The xTool P2 is more than just a powerful machine; it's a smart one, too. Equipped with two 16MP smart cameras, it captures a live preview of the working area, automatically focusing on the material.
Its automatic passthrough feature allows for continuous feeding of material, making it possible to work with plastic up to 118 inches in length.
You can engrave on spherical and cylindrical objects using the rotary attachment. This increases its versatility.
The machine is completely safe, with features like a completely enclosed design, an automatic lid lock, and an emergency shutdown button. Additional features like exception warnings and a fire safety kit ensure that you can operate the machine with confidence.
Laser Engraving Plastic Project Ideas
Laser cutting and engraving opens up a world of possibilities. Here are just a few examples of laser cut and engraved plastic projects.
Laser Engraved Plastic Light
The acrylic light is a mesmerizing piece of laser art. First you need to cut the acrylic in the desired shape and engrave the pattern you like. You can engrave names, pictures, or anything you like. Finally, place the acrylic sheet over the lamp base. Turn on the light, and you will see the mesmerizing reflection on acrylic. Beside being a decor item, it makes a great gift as well.
Laser Cut Plastic Wall Clock
Who says clocks can't be art? You can transform a simple plastic sheet into a stunning wall clock with a laser machine. Modern geometric patterns, floral motifs, or even a family photo – the possibilities are endless!
Laser Cut Plastic Cake Toppers
Make any celebration extra special with custom cake toppers. Laser cut shapes, names, initials, or even characters to add a unique touch to your cakes. These toppers are guaranteed to be a conversation starter at your next party.
Personalized Plastic Signs
Laser cutting and engraving lets you create custom signage for any purpose. Create custom business signs, welcome signs for your home, or even personalized room signs for the kids.
Airpods Engraving
Tired of mixing up your AirPods with others? Laser engraving lets you personalize your charging case. Add your initials, a monogram, or a fun design to easily identify your AirPods and add a touch of flair.
FAQs of Laser Cutting Plastic
1. How Thick of Plastic Can be Laser Cut?
The thickness of plastic that can be laser cut depends on the type of plastic and the power of the laser. For example, xTool P2 CO2 laser cutter can cut acrylic up to 20mm in one pass.
2. Can a Fiber Laser Cut Plastic?
Fiber laser engravers achieve great results for engraving plastic. But they're not recommended for cutting plastic.
Conclusion
Laser machines are the best for engraving and cutting plastics because they offer fine and excellent results in the shortest time. The accuracy, performance, and speed of the machines are incredible.
But before laser engraving or cutting plastics, you must know what kind of plastic is suitable for lasers. There are some plastic types that create hazardous and toxic gas. We have discussed all these types of plastics that you can cut and cannot cut. Once you know the suitable plastics, you can make a wide range of products.
