Laser Cutting Thickness Choosing Guide
There is no simple answer on the thickness a laser system can cut. http://am.co.za/ Since a laser is a light, it will lose power on propagation and reflection, and tends to be more complex when the machine size is larger. http://am.co.za/ So we have compiled this guide for the laser system that we sell, which gives you a good idea of all kinds of materials that a laser can mark, engrave, drill and cut from the commercially available options that we provide.

#1 Laser Generating Device is mounted on Gantry on Flatbed model, therefor the length of cutting table won't effect the cutting efficiency. http://am.co.za/ General speaking, the laser cutting machines require to achieve laser efficiency higher than 90% with laser beam travel distance less than 3 metres.
#2 There is no absorption problem of laser light from either a Nd:YAG (1.06 microns) or CO2 (10.6 microns) laser in nitrogen, or in air without contaminants. http://am.co.za/ In real working environment, air has variable percentages of CO2 and water vapor and also tends to contain hydrocarbons, all of which absorb 10.6 um light. http://am.co.za/ If you do not have clean and dry working environment, the decrease of laser power is dramatically increase from 3% energy lose per meter to 20% or more per meter.
Laser Cutting Gas
A small air pump is included and functions as the default cutting air source for all our CO2 laser cutting tables. http://am.co.za/ Stronger pressure cutting air sources may be required if you are going to employ the melt and blown cutting method for non-metal materials, especially plastic materials. http://am.co.za/ This is to say, for melt and blown cutting on metal, except stronger air pressure requirements, as the cutting air compound may require to be replaced with oxygen or other metal cutting assistance gas for better cutting quality. http://am.co.za/ Otherwise, the molten dross tends to adhere to the underside of the cut surface. http://am.co.za/ For exceptionally clean cuts, very high gas pressures can be used.
Laser Lens & Lens' Focus Length ( FL )
The longer of the lens' Focus Length the longer the Depth Of Field ( DOF ) which increases the cutting thickness. http://am.co.za/ Increasing of FL, however, also results in bigger Spot Size on material, which means a wider cutting gap ( Kerf ) and lower energy density meaning that less material can be cut. http://am.co.za/ Customized lenses will provide any FL, commonly commercially available lenses are:
|Focus Length ( FL )|

indicates the Zinc-Selenide (ZnSe) Lenses we sell and the price associated with Lens diameter ( Φ ). http://am.co.za/ We may expand our product range later with additional sizes. http://am.co.za/ Focus length 50.8 mm for smaller table and 63.5mm for larger table are the most commonly used FL and is installed as the default focus lens for most our CNC Laser Cutters.

- NOT ≤ 5%
- Poor ≤ 20%
- Fair ≈ 40%
- Good ≈ 60%
- Very Good ≥ 80%
- Excellent ≥ 90%
- Temperature required to melt the material, useful to laser welding as well as blow cutting. http://am.co.za/ Not all materials can melt.
or.. Burning Temperature http://am.co.za/
- Temperature required to vaporize the material, useful for laser cutting. http://am.co.za/ Everything can be vaporized when the temperature rises enough. http://am.co.za/
If the material will burn at vaporization temperature, a risk of fire is tremendous as well as a burning marks being visible on the cutting edge.

Wavelength is µm for laser. http://am.co.za/ Laser beam's widest diameter is mm, therefor all mirror sets and lenses should be chosen with required diameter larger than mm. http://am.co.za/ With laser duty cycle %, theoretically Watt ( with occasionally burst to Watt ) of laser energy will be delivered to the material on the cutting table.

While there are some laser cutters that can cut material as thick as 20 mm, most machines work on materials closer to 0.5-12 mm thick, depending on what's being cut.What is the best thickness for laser cutting? ›
In general, you want wood that's no more than 1/2” thick. A 1/4” piece would be ideal. For the 1/2” piece, you'll need a 90-watt CO2 laser, and for 1/4” you'll need half the power.How thick of wood can a 40W laser cutter cut? ›
40W Laser. You can typically cut up to 5 mm acrylic, 6 mm soft woods using a 40w laser.What setting do you use for laser engraving on wood? ›
Wood engraving techniques:
Most wood can be engraved using full power no matter whether you are using a 25-watt laser or a 120-watt laser. Depending on the wattage of your laser, the best approach is to set the laser power at 100 percent and adjust the speed to obtain the desired depth.

Cutting Thickness:0-0.8 ”(Depends on the material and thickness.)
An 80 watt laser can cut plywood up to 1/2 inch thick. Make sure to use a high pressure source of air to knock out all of the charring during the cutting process so the laser can work efficiently.How thick should a plywood laser cutter be? ›
What thickness plywood can a laser cutter cut? You can cut plywood up to 15 mm thick with a laser machine.What is the best format for laser engraving? ›
For laser engraving acceptable file formats include the following: TIFF, BMP, JPG or other Raster images that are 1-Bit black and white camera ready artwork. No Gray scale. Should be in a minimum of 300 DPI resolution.What power laser for engraving? ›
If you'll be using the laser primarily for engraving, the best results may be achieved with a laser power of between 25 to 80 watts. In order to maximise productivity when laser cutting, when speed is paramount, we suggest a laser power of in excess of 80 watts.Should I sand wood before laser engraving? ›
The surface of the wood needs to be as smooth as possible before engraving, this is achieved by sanding the surface to remove loose fibres of wood and uneven areas. The laser engraves the design or text and once the depth and finish are achieved the wood is sanded to remove any residue.How thick will a 1000W fiber laser cut? ›
1000W fiber laser cutting machine is used to cut 6mm thick carbon steel with a maximum cutting speed of 1.4m per minute. 1500W fiber laser cutting machine is used to cut 6mm thick carbon steel with a maximum cutting speed of 1.5m per minute.What can a 150W laser cut through? ›

A 10 watt and 10 watt+ laser can easily cut wood, plywood and dark acrylic, up to 1/3'' thick with a few passes, but with white acrylic or plastic it might be a problem since the 445 nm wavelength beam will be more likely reflected from the acrylic surface and will be unable to cut at all.How thick can a 12kW laser cut? ›
Solid state 12kW laser power ensures our ability to achieve excellent feed rates and cutting speeds including the capability to cut mild steel up to 30 mm thick and standard sheet sizes of 3000 mm x 1500 mm with a max weight of 1800 kg for one pallet.
