​Detailed Product Info & Reviews


​1. Dremel LC40 Laser Cutter and Engraving Machine

31XO3rNsroL. SL500

This 40-watt infrared laser not only engraves but also cuts a range of materials including aluminum, wood and plastic. It produces its creation by slicing through soft materials, cutting wood (up to a quarter-inch), engraving designs into plastics and acrylic material 6mm thick.


​Built-in Software

The manufacturer took a rather interesting approach for the LC40. This is because the software used to set up and control the laser cutter is built-in. Thus, users can control the machine via the web interface or touch screen.

Its touch screen is used to set up the cutter and print files from the machine memory or USB drive. Many users prefer using the web interface to control LC 40 as they can use their mobile devices and laptops without disruptions.

Preset Functions

The software is designed with a range of functions for the different materials you are working on. You just need to activate the scan setting for the machine to scan to engrave or cut the material. This preview process allows you to see how the image will look like before engraving it. The feature comes in handy when you want to engrave an odd-shaped piece of metal.

The presets also allow you to use the appropriate settings for the material you are cutting or engraving. Once the image is uploaded into the cutter, you just need to press the button and the machine automatically adjusts the setting to the ideal laser speed and power for that material.

The Size

The machine is three feet wide and two feet deep which some people will find a little too large. This means you need lots o space to set it up. What’s more, you need to connect it to the water cooler at the back of the cutter using three tubes and a cable. This takes up more space especially because you need to connect the vent tube and fan to a dryer vent or window.

What I Like

I found the Dremel LC40 Laser machine pretty easy to use thanks to its built-in camera which scans the material, uploads the design using the web interface while the cutter engraves the design.

​Laser Engraver Buyer’s Guide

Buying a laser engraver for metal is a significant investment. It’s not just about the initial capital outlay but the impact it has on the entire manufacturing process. Buying the wrong equipment means you will be stuck with an irreversible decision for a long time. it is important to get it right from the onset. Here’s how:

CO2 or Fiber Technology

There are two types of lasers in the industrial market: the new solid-state fiber glass lasers and COCO2 gas lasers. COCO2 lasers are pretty traditional and have been the foundation of metal fabrication in the last two decades.

They are powered by electricity using a gas-filled resonator and mirrors to focus and deliver the beam. Fiber laser technology was only introduced in 2008 and has become more popular than COCO2 gas lasers. It uses banks of diodes to create the laser bean which is channeled and amplified via fiber-optic cable.

Fiber laser engravers have lower operating costs and high cutting speeds than COCO2 lasers. Initially, laser engravers were designed to cut thin materials. However recent upgrades enable fiber lasers cutting materials as thick as 0.5 inches at robust cutting speeds.

Additionally, the machines can cut reflective material like copper and brass which is challenging when using COCO2 lasers. It does not mean COCO lasers are obsolete; some applications remain ideal for COCO2 lasers. For example, applications that need good edge quality on thick or specialized materials need COCO2 lasers.

The Size and the Power of the Machine

The size of the machine’s bed determines the size of material that can fit in the machine to cut or engrave. Machines with larger beds engrave larger and small pieces, and allow the user to cut multiple pieces simultaneously.

You also need to look at the ergonomics; do you want a fixed bed or one that goes up and down. The latter enables the user to engrave metals with different sizes.

When it comes to the power of the laser, metallic material needs lasers with a higher power output than any other material. As such, laser engravers for metals should have a power output of 300 W and above. 300-W laser can cut through thin steel material but for 2-mm or thicker steel sheets you will need 500 W and above.

Material Handling

An automatic material handling equipment gives you control depending on the nature of application. Do you want to run the laser for a few hours or in shifts? You also need to consider if the operator prefers manual loading or unloading of the laser based on the time taken to process a metallic sheet.

Additionally, if reducing the labor cost is an essential aspect of the production cost, then automatic equipment provides greater efficiencies. However, if you want to use a manual laser engraver before buying an automatic one, ensure the pallet system and automatic storage are easy to add.

Whether to Buy or Lease

Laser engravers for metals are pretty expensive for the average hobbyists. Low power machines like 100 W engraver is relatively affordable but barely delivers when it comes to cutting metal surfaces. The ideal metal cutting lasers should have 300 W and above which cost $10,000 or more. What’s more, you need to include the cost of gas.

If the cost of owning a laser engraver for metal is too high you should consider subcontracting. It eliminates the cost of buying the machine and is ideal if you have flexibility with lead times.

Need for New Software

Manufacturing companies already have a software package that employees are used to. As such, it is important to determine if the existing software is compatible with the new laser machine. If you need to purchase different software consider the new capabilities that come with the new software. Also, think about how the new software will be integrated into the company’s network.


(Q) How Do I Connect the Engraving Machine to the Computer?

​(A) laser engravers provide USB connection. However, there are others that allow Bluetooth and wireless connectivity like the Dremel LC 40. If you don’t have plenty of working space, consider a machine that supports wireless connectivity.

(Q) What Type of Metals do Laser Engravers for Metals Cut?

(A) The machines are designed to cut into metals like copper, brass, nickel, tungsten and titanium. However, you need to check the power and speed capabilities of the device to verify that it supports this feature.

(Q) Do Laser Engraving Machines Have Dual-capability?

(A) Most machines are designed to cut and to engrave materials. Its best to check the specifications if you are looking for a machine with dual features.

(Q) How can I Improve Laser Engravings on Metal?

(A) A range of factors affect the quality of your laser engravings. First, you need to calibrate your laser. Begin by testing a series of files from 10-15 with an increment of 1 mm. compare the results and choose the laser engraving with the thinnest solid line.

Also, keep you laser engraver clean. Use a kitchen cloth to wipe the parts and pay extra attention to the laser lens and the machine head. The parts should be free from smut and dust to avoid laser engraving mistakes.

(Q) Which is the Ideal Cooling System for a Laser?

(A) Industrial-grade lasers need constant cooling. Cooling systems made from metal or ceramic last longer usually 5-6 years. However, they are more expensive than systems made from glass. Glass cooling tubes use water to cool the machine but you need to place a bucket next to the laser engraver to collect the waste water.


Clearly, laser systems for metal come with highly customizable parameters to enable users to make high-quality markings on metallic items. Different metals have different needs it’s up to you to choose a versatile machine. Our first two picks the Triumph Fiber Laser Marking Machine and Dremel LC 40 makes it easy for users to customize the machines to the needs of the material. However, is they are out of range consider buying the Kohster 80 W laser machine. It has similar capabilities and is more affordable.
