2. Corrugated cardboard: Corrugated cardboard is the first choice for courier and cargo boxes. Corrugated cardboard usually has a wavy sandwich in the middle and is highly compression-resistant.

Advantages of laser cut cardboard

There are many advantages of Laser cut cardboard, a few of which will be listed below:

1. High precision: Laser cutting cardboard can cut at a very fine level to achieve exact designs.
2. High speed: Laser cutting cardboard can finish the cutting task quickly, thus increasing production efficiency. And you can mass-produce several of the same goods.
3. High flexibility: Laser cutting cardboard can be cut in different shapes to meet various design requirements.
4. No contact operation: When Laser cutting cardboard, the laser head does not touch the cardboard, so there is no loss of the machine during the cutting process. So there is no need to worry about the deformation or damage of cardboard during the cutting process.
5. Environmental protection: The laser cutting process does not need to use chemicals and does not produce harmful fumes, so it is relatively environmentally friendly.

Cons:

Improper operation can easily cause fire, need to prepare fire extinguishers and other safety measures.

What is the max thickness of laser cut cardboard?

The maximum thickness of laser cut cardboard depends on the power of the laser cutting machine being used. Generally, a laser cutter can handle cardboard up to about 1/4 inch (6mm) in thickness. However, some more powerful machines can handle thicker materials, up to 1 inch (25mm) or more. It is important to check the specifications of your specific laser cutting machine to determine its maximum cutting thickness for cardboard.

CO2 laser cutter

The CO2 laser cutter is the first choice for cutting cardboard. It is ideal for cutting cardboard, wood, paper, and non-metallic materials. Typically a 50w laser cutter can cut paper up to 10mm.
A 50w CO2 laser cutter costs between $2500-6000. The price will be higher if you want to buy a machine with more power or a larger working area.

Diode laser cutter

A diode laser cutter can also cut cardboard and paper, but it is limited to the thickness of the paper it can cut. And it is a more economical choice, usually only costing $200-1000 to buy a desktop laser engraver.
If you need to cut paper frequently, buying a diode laser cutter with more power is recommended.

How to laser cut cardboard?

Laser cutting cardboard can be a precise and efficient way to create intricate designs or precise shapes. Here's a step-by-step guide on how to laser cut cardboard:

Prepare your design and cardboard

Start by creating or obtaining the design you want to laser cut. You can use graphic design software such as Adobe Illustrator, CorelDRAW, or even online design tools. Make sure your design is in a vector format (such as SVG, AI, or DXF) so that it can be easily imported into the laser cutting software.
It's best to use a relatively thin and consistent cardboard with minimal variations in thickness. Avoid materials with coatings or finishes that could release toxic fumes when cut.

Set up your laser cutter

Ensure that your laser cutter is properly set up and calibrated. Follow the manufacturer's instructions for your specific laser cutter model. Check that the lens and mirrors are clean and in good condition.

Secure the cardboard

Place your cardboard sheet on the laser cutter bed and secure it in place using masking tape or a dedicated material-holding system. Ensure that the cardboard is flat and taut to prevent any warping during the cutting process.

Adjust the laser settings

Configure the laser settings based on the thickness and type of cardboard you're using. Consult the laser cutter's manual or the manufacturer's guidelines for recommended settings. Typically, you'll need to adjust parameters such as power, speed, and focus distance.

Import and position your design

Import your design file into the laser cutting software. Position it on the virtual representation of the cardboard sheet to ensure it fits within the cutting area. You can also arrange multiple designs to optimize material usage.

Test the settings

Before cutting the actual design, it's wise to perform a test run on a small area of the cardboard sheet. This allows you to verify that the laser settings are correct and that the design will be cut as intended. Make adjustments if necessary.

Start the laser cutting

Once you're confident with the settings and alignment, start the laser cutting process. Most laser cutters have a control panel or software interface where you can initiate the cutting operation. Ensure that you are in a well-ventilated area or have proper exhaust systems to handle any smoke or fumes generated during cutting.

Monitor the process

Stay attentive and monitor the laser cutting process to ensure everything is running smoothly. Avoid leaving the machine unattended during operation.

Remove the cut pieces

Once the laser cutting is complete, carefully remove the cut pieces from the laser cutter bed. Use caution, as the edges of the cut cardboard may be hot immediately after cutting. Allow the pieces to cool down before handling them further.
Remember to practice proper safety precautions when using a laser cutter, such as wearing protective eyewear and following the manufacturer's guidelines.
