Introduction: A Practical Way to Cut Cardboard
Learning how to laser cut cardboard can help makers, small businesses, designers, and hobbyists create clean packaging, prototypes, signs, models, and decorative projects. A co2 laser cutter offers a precise way to cut and engrave cardboard without using traditional blades or complicated manual tools. For users who want a compact machine with useful cutting power, the Monport Reno45 Pro 45W Desktop CO2 Laser Engraver and Cutter provides a 400 × 300 mm working area, up to 600 mm/s engraving speed, and a 100 mm adjustable Z-axis.

Why Use a CO2 Laser Cutter for Cardboard?
Cardboard is popular because it is affordable, lightweight, and easy to work with. However, getting straight and repeatable cuts by hand can take time. A co2 laser cutter uses a focused laser beam to follow a digital design, making it useful for detailed shapes, slots, holes, lettering, and prototypes.
For businesses, this can reduce repetitive manual cutting and make it easier to reproduce the same design. For hobbyists, it opens more possibilities for crafts, architectural models, packaging, and personalized projects.
How to Laser Cut Cardboard Step by Step
Knowing how to laser cut cardboard starts with preparing the material and design correctly.
- Prepare your design: Create or import your artwork into compatible software such as LightBurn or AutoLaser.
- Choose suitable cardboard: Use clean, untreated cardboard and test a small section before starting a larger project.
- Position the material: Place the cardboard flat on the honeycomb or blade working platform.
- Set the focus: The Reno45 Pro uses magnetic assisted focus, allowing users to focus the laser in a few seconds.
- Set your cutting parameters: Power and speed depend on the cardboard type and thickness. Begin with a test cut rather than immediately using high power.
- Start the job: Check alignment and monitor the cutting process.
- Inspect the edges: Remove the finished piece and check whether the cut is complete and clean.
What Can the Reno45 Pro Handle?
The Reno45 Pro is designed for more than cardboard. Its 45W CO2 laser can work with a range of suitable non-metal materials, while its strong cutting performance allows it to cut acrylic up to 15 mm thick under appropriate conditions.

| Maximum engraving speed | 600 mm/s |
| Z-axis movement | 100 mm |
| Working platforms | Honeycomb + blade |
| Connection | USB + WiFi |
| Software | LightBurn, AutoLaser, TopwisdomLaser |
| Operating systems | Windows, macOS, Android, iOS |
Can It Cut Foam?
The Reno45 Pro can cut ordinary foam materials around 20–30 mm thick, depending on the specific material and settings. However, industrial-grade foam such as polyurethane (PU) or polyethylene (PE) is denser and more difficult to cut efficiently. For these materials, a 100W CO2 laser or higher is recommended.
Material safety is important. Some foams, including PVC and certain flame-retardant foams, can release toxic gases when processed. Always verify the material composition and use proper ventilation or a suitable fume extraction system.
More Than Cutting: Engraving Glass and Eggs
A major advantage of this co2 laser cutter is its ability to handle creative engraving projects beyond flat materials. The Reno45 Pro can engrave glass tumblers when used with a compatible rotary attachment. This makes it useful for personalized drinkware, gifts, and small-batch products.
It can also engrave empty eggshells, giving makers another option for delicate decorative projects. These applications demonstrate why a versatile desktop laser can be valuable for both creative and commercial work.
Designed for Small Workspaces
The Reno45 Pro has a 400 × 300 mm working area while maintaining a relatively compact desktop form. Its dual working platforms provide flexibility for different materials, while the adjustable 100 mm Z-axis gives users more room when working with objects of different heights.
The hidden front passthrough design can also provide additional processing flexibility for suitable projects.
Easy Focusing and Software Options
Beginners often worry that laser machines are difficult to operate. The Reno45 Pro addresses this with magnetic assisted focusing and an LCD control panel. Users can choose AutoLaser or LightBurn depending on their workflow.
LightBurn compatibility is especially useful for users who already have experience with laser design and control software. WiFi and USB connectivity also provide convenient ways to transfer designs.
Important Safety Details
Laser cutting should always be performed in a properly ventilated environment. Keep the machine monitored while operating, use the recommended protective equipment, and confirm that every material is safe for laser processing. Never assume that a material is safe simply because it looks similar to cardboard or another familiar material.
