Complete Answer: The manufacturer states that the life of the laser tube is between 1200 and 2000 hours. The 2000 hours can be related to using the laser for 8 hours per day, 5 days per week, and 50 weeks per year.
What is a K40 Laser Cutter?
A K40 laser cutter is essentially a term used for affordable engraving machines with 40W power. They’re not restricted to one manufacturer or even design, although most do look very similar, with a simple rectangle box design and a blue-colored base.
K40 Laser Cutter Bed Size
K40 laser cutters have an engraving area, also known as bed size, of 300m x 200mm. This provides enough room to work on most medium size projects, such as drinking glasses, leather wallets, and so on.
K40 Laser Cutter Uses & Applications

K40 Laser Cutter Upgrade & Modification
All K40 laser engravers come with the same fundamental parts – a CO2 laser tube, a focus lens, stepper motors, a coolant pump, an exhaust fan, and a control board with a power supply – and all of these can be upgraded.
K40 Laser Specs
Here’s a full list of the specs you’d expect on a standard K40 laser machine.
The Best K40 Laser Engraver Machines
The Vevor K40 Laser Cutter is an example of a big CNC brand getting in on the K40 laser act. This is one of the cheapest yet most impressive K40 lasers on the market.
Step 1: Savety First
If you deside to build a laser cutter in general and a CO2 laser cutter in special you have to consider that you must take precautions to not hurt yourself or others with direct or reflected laser light. Where the light of a diode laser is mostly visible, that of a CO2 laser isn't! Furthermore the power of a CO2 laser is much higher.
Step 2: Things You Need
Besides the old 3D printer I had, wat was good for: two steppers, a power supply, axels, a led strip, wire, switches and a load of torx screws, I needed a laser tube, a laser power supply, mirror/lens set, an air pump, a water pump, a water container, silicon tubing, enough mdf material to make the cabinet, a sheet of polycarbonate and thin aluminium plate.
Step 3: 1st Step.
At first I demolished the old 3D printer and on the 1st picture you see the flipped over x,y- running gear. From this part I have taken away the original guiding parts for the axles (black) and print my own (orange). The new parts I printed are tailor made to house the mirror/lens set (gold colored) I have bought.
Step 4: The Cabinet
Pic 1: the whole ground plate (85x60 cm) where I drawn where the side plates and laser compartment will come. You also see some printed parts (white and orange).
Step 5: Holes
On this pic you see the cabinet with some round holes and square holes. The most left round hole is the exhaust air hole, the round hole in the back plate is the hole were the laser beam comes trough, the round hole on the right and the narrow square hole on the right in the back are air intake holes.
Step 6
This is the power supply extracted from the Davinci. I have placed some terminals to make the power connections to all the electronics and motors.
Step 7: More Steps..
pic 1: electronics. On the left of the Arduino with CNC shield, you see a green board. This is an adaptor board I made for the end-switches and the logic invertor. The adaptor is needed because I use end-switches with a status led wich uses three leads in stead of two (one extra 5V for the led), the CNC-shield uses two-lead connections.
How much does a K40 laser cost?
The “K40” Laser is a catch all term for the blue (and sometimes red), water cooled Chinese made lasers you find for around $300-400 USD on Amazon and Ebay. There is no single manufacturer or official design spec for these, and they are all slightly different, but work on the same or at least very similar principles, a blue sheet metal box, containing an (allegedly) 40 watt laser (but usually closer to 30 watts), using roughly similar controls (some are analogue, some are digital), and with roughly similar connections.
What can you do with a laser cutter?
One of the most important modifications you can make to your laser cutter is setting up an air assist. This blows the smoke and other debris away from the cutting beam and ensures that you are always cutting at full power, meaning less chance of fires and cleaner, more consistent cuts. It’s not really required when engraving, but for cutting it’s a must have.
How to keep water cool with laser cutter?
In order to keep the water cool you have two options, either purchase a water chiller that will run your $100-150, OR get some bottles of water and stick them in the freezer. Add them to your bucket like giant ice cubes and then refreeze them after you’ve finished running your laser cutter.
How hot should water be for laser cutters?
As mentioned earlier these laser cutters are water cooled. Ideally you want to keep the water around 15-20 degrees celsius maximum (Some suggest aiming for around 18c for optimal power output and extending the life of your laser).
What is a CW-3000 water chiller?
A “CW-3000” Water Chiller (or you could just put frozen bottles of water in your reservoir like I plan to): These are chillers designed for use with laser cutters. Though just like the K40, they are all clones of whatever the original design was, so you are rolling the dice with these, and quality may vary.
Is electrocution safe?
Because of this, you do need to take some very sensible safety precautions to prevent the following risks: Electrocution: Depending on which one you get, it can either be (reasonably, I’ll get to that) safe, or a complete and utter death trap. Out of the box, even the ones that are properly grounded, aren’t.
