Laser engraving is a popular method for customizing and cutting various materials, but one common concern for users is energy consumption. Whether using a laser engraver for business or personal projects, understanding power usage can help you estimate costs and improve efficiency. So let’s answer this important question: Do laser engravers use a lot of electricity?
This guide explores how much electricity laser engravers consume, factors that affect their power usage, and tips to minimize energy consumption.

Understanding Power Consumption of Laser Engravers
Types of Laser Engravers and Their Power Usage
Different types of laser engravers consume varying amounts of electricity, depending on their power rating and efficiency. Here’s a breakdown:
Laser Type | Typical Power (Watts) | Average Power Consumption (kWh) |
|---|---|---|
Diode Laser | 5W – 20W | 0.05 – 0.2 kWh |
CO2 Laser | 30W – 150W | 0.3 – 1.5 kWh |
Fiber Laser | 20W – 100W | 0.2 – 1.0 kWh |
Diode lasers generally use the least power, making them ideal for home or hobby use. CO2 and fiber lasers, commonly used for industrial and professional applications, consume more electricity due to their higher wattage.
Factors Affecting Energy Consumption
Several factors influence the amount of electricity a laser engraver uses:
- Power Rating – Higher wattage machines consume more energy.
- Engraving Time – Longer operation times lead to higher energy consumption.
- Material Type – Some materials require more power to engrave or cut effectively.
- Efficiency of the Machine – More advanced models optimize power use for better performance.
- Cooling Systems – Some laser engravers use additional power for cooling (e.g., CO2 lasers with water cooling systems).
Estimating Energy Costs
To estimate the electricity cost of running a laser engraver, use the following formula:
Energy Consumption (kWh) = Power (W) × Time (hours) / 1000
For example, if you use a 50W CO2 laser for 2 hours per day:
50W × 2 hours / 1000 = 0.1 kWh per session
Assuming an electricity cost of $0.15 per kWh:
0.1 kWh × $0.15 = $0.015 per session
Over a month (60 hours of use), this would cost $0.90. Industrial machines with higher wattage will naturally incur higher costs.
Factors That Affect How Much Power a Laser Engraver Uses
Now that you know how much power a laser engraver can use, it’s important to note that this number can vary depending on the following factors:
Actual Working Time
The actual working time is the amount of time the laser will take to perform the cutting engraving process.
Used Laser Power
The laser power used is the amount of laser power your engraver consumes while cutting or engraving. This number can vary depending on the type of material and design you’re working with, so it’s important to consider this when calculating your electricity usage.
Peripheral Equipment
Using any additional equipment with your laser engraver, such as an extractor fan, will also increase the amount of electricity it uses.
Size of the Engraved Area
The size of the area being engraved can impact the amount of power your laser engraver consumes. Larger areas require more power to engrave and can increase the amount of electricity used.
The Size of Your Machine
Laser engravers vary in size; some are small and portable, while others can be quite large. Generally speaking, the bigger the laser engraver is, the more power it will require to run.
The Type of Material You’re Engraving On
Different materials require different levels of power to be successfully engraved. For example, aluminum requires more energy than wood, and laser engravers will use more power if they engrave on a material that requires a higher energy level.
The Power Settings
You can set the power settings on your laser engraver to use more or less electricity. When you are using a high-power setting, the machine will use more electricity, and vice versa.
The Frequency of Use
When you are using your laser engraver frequently, it will use more power than when you are not using it. So if you plan on using the machine often, make sure to factor in this additional electricity usage.
How to Use Your Laser Engraver Effectively
While laser engravers are energy efficient, here are a few steps you can take to ensure you are using your machine as efficiently as possible:
Check Power Settings
You should ensure the power settings are set at the correct level for your specific material and design. This will help to ensure that you are using the minimum amount of power required to get the job done.
Turn it Off When Not in Use
When you’re not using your laser engraver, make sure to turn it off. Doing so will reduce the amount of electricity you are consuming and help save energy.
Regularly Clean Your Laser Engraver
Regularly cleaning your laser engraver will help ensure it runs at peak performance. This means that your machine won’t be using more power than necessary, helping you save energy in the long run.
Also consider
- Choose the Right Laser Type: Fiber lasers are more energy-efficient for metals, while CO2 lasers work best for wood and acrylic.
- Use Air Assist and Proper Cooling: Keeping the laser lens clean and ensuring efficient heat dissipation can improve performance and reduce wasted power.
- Select Efficient Materials: If possible, choose materials that require less power to engrave while still meeting your design needs.
How Do Materials Affect Laser Engraver Power Consumption?
When using a laser engraver, the type of material being engraved significantly impacts power consumption. Different materials require varying levels of laser intensity, speed, and duration, all of which contribute to overall energy usage.
Understanding these factors can help you optimize efficiency and reduce operational costs.
Factors That Influence Power Consumption
- Material Density
Dense materials, such as metals and hardwoods, require higher laser power to achieve precise engraving or cutting. This increased power output leads to higher electricity consumption. - Reflectivity
Highly reflective materials like stainless steel or aluminum require more laser energy to penetrate their surfaces, as a portion of the beam is reflected rather than absorbed. Fiber lasers, which are more efficient at engraving metals, consume less power compared to CO2 lasers. - Thickness of the Material
Thicker materials demand multiple passes or slower engraving speeds, leading to prolonged laser operation and greater energy usage. Thinner materials, such as paper or fabric, require less power and shorter engraving times. - Material Composition
Some materials absorb laser energy more efficiently than others. For instance:- Wood: Requires moderate power; softer woods consume less energy than hardwoods.
- Acrylic: Needs high power but engraves cleanly with CO2 lasers.
- Metal: Requires fiber or CO2 lasers with high power settings, increasing electricity usage.
- Leather and Fabrics: Typically require low to moderate power, making them more energy-efficient.
- Engraving vs. Cutting
Cutting through materials generally consumes more power than surface engraving, as the laser must penetrate deeper. Intricate designs that require multiple passes also add to the total energy cost.
The type of material you engrave directly affects laser engraver power consumption. Understanding these material properties allows you to make informed choices that balance efficiency, cost, and quality. By adjusting settings and selecting appropriate materials, you can minimize energy use and maximize engraving efficiency.
Frequently Asked Questions
How much power does a laser engraver use?
The power consumption of a laser engraver depends on the type and wattage of the machine. Diode lasers typically use 10-50W, CO2 lasers range from 40-150W, and fiber lasers can consume 200W or more. Additionally, power usage increases with auxiliary components like cooling systems and air assist.
Is laser engraving energy efficient?
Yes, laser engraving is energy efficient compared to traditional cutting and engraving methods. It uses focused laser beams with minimal waste and precise power control, reducing overall energy consumption. However, efficiency varies by laser type and power settings.
How much does a laser cost to run?
The cost to run a laser engraver depends on its wattage, usage time, and electricity rates. On average, a 50W laser running for an hour consumes about 0.05 kWh, costing a few cents per hour. Higher-powered lasers will cost more.
Final Thoughts
Laser engravers do consume electricity, but the amount varies depending on the type, power rating, and usage habits. For hobbyists and small business owners, the cost is typically low, while industrial users may see higher electricity expenses. By choosing an efficient machine and adopting energy-saving practices, you can minimize costs and maximize productivity.
