5 Things to Know Before Buying Laser Air Compressor

What specs do I need to look at when buying a compressor?

I'm currently in the process of building my first DIY 90 watt laser cutter. Which is a fun project since I have near zero experience with laser cutting. If some find it interesting of course I'm happy to share my progress pictures.

You can find more information on our web, so please take a look.

Anyway, I'm currently researching my options for air assist. Of course I could just buy a 'standard Cloudray pump', but as most of you know, the results when using a real compressor are usually much better.

Unfortunately I don't have a lot of space for a huge compressor. And since it will be used in a room which is directly connected to the house, it can't make a lot of noise. So these restrictions really limit my options.

I found this nice compact compressor: Senco AC Olievrije Stille compressor

But I have no idea if these specs will work for using it with a laser cutter. The thing I'm most worried about is the volume: 5 liters. Is this an option? Or do I need a much bigger tank?

Can anyone give me some specs I should keep in mind when selecting a compressor?

Or is it smarter to go for the standard Cloudray pump and upgrade later?

Thanks for all your help!

Understanding Key Specs for Laser Air Compressors

When it comes to selecting the right compressor for your laser cutter, there are specific specs you need to prioritize:

1. Compressor Capacity

A common concern is the volume capacity of the compressor. While a 5-liter tank, like the one in the Senco AC Olievrije Stille compressor, can be manageable for smaller tasks, it might not sustain continuous laser cutting sessions. If you anticipate extended usage, consider a compressor with a larger tank size.

2. Noise Levels

Given that your workspace is directly attached to the house, noise would indeed be a major issue. Look for compressors marketed as "quiet" or "low-noise". This ensures that your laser cutting doesn’t cause significant disturbances at home.

3. Pressure and Flow Rate

The efficiency of your compressor is largely influenced by its pressure (measured in PSI) and its airflow rate (measured in CFM). High precision laser cutting requires consistent airflow to keep the laser lens clean and clear debris. Ensure your choice meets or exceeds the specifications recommended for your laser cutter.

4. Oil-Free Compressor

Opt for an oil-free compressor, which reduces maintenance and the risk of oil mist contaminating your laser workpieces. The Senco AC Olievrije Stille compressor is a good example of an oil-free option that can be ideal for home environments due to its clean operation.

5. Size and Portability

Since space is a constraint, the physical footprint of the compressor is critical. Compact and portable options can offer the flexibility needed in a limited workspace without compromising performance.

In this article, we'll cover some knowledge before buying a suitable laser engraving machine. Here we go:

What are laser engraving machines?

LASER is the acronym for Light Amplification by Stimulated Emission of Radiation. Laser engraving is the process of subtractive manufacturing to engrave material surface using a laser beam. It is a non-contact process, as the high heat and energy of laser melts and vaporizes the area where you are aiming the laser beam at.

Finally, it leaves a permanent mark on the surface, usually used to create an image of the material. With graphic software and parameter, laser engraving can produce amazing effects, such as photo or 3D engraving.

How does a laser engraving machine work?

A CO2 laser works by electrically stimulating the molecules of a carbon dioxide gas mixture. When focused through a lens, this invisible intensive beam can vaporize many materials. Depending on the speed and intensity of the beam, CO2 laser can be used to engrave a wide variety of materials.

For customers, it is fairly easy to operate the laser system for engraving and cutting, similar to the way your paper printer prints. You can install most kinds of graphics software in the Windows system, such as CorelDraw, to design the graph you need. Set the page size to the same as the plaque, trophy, or other objects you will be engraving, and print it to the laser. With adjustable speed settings from 0.1% to 100%, power settings from 1% to 100%, and dpi settings of up to , the engraver will print with as much depth and detail as you need.

There are two ways how a laser engraver works; one is raster, and the other is vector. Raster is like a high clarity lattice printing, where the laser head scans left to right, engraving a series of dots one line at a time, then moves back and forth to carve as many lines as needed to make up a full-page picture or characters. Different from raster, vector proceeds on the outline of the characters. We usually use this model for cutting materials, like woods, acrylic, and paper, or marking on the surface of them.

What is a laser engraving machine used for?

The versatility of laser system means that it works on many materials, including wood, acrylic, plastics, stone, metals, etc. In particular, it is a great tool to add numbers, logos, images, and serial numbers to parts. Laser engraving is today a technology commonly used for producing promotional products like pens, signs, and displays, which makes laser engraving suitable for a variety of industries, such as signage and advertising, personalization and identification, gifts and promotions, post-press, apparel, and electronics industries.

One of the most noticeable applications is customization which is popular nowadays, like a wedding ring with a name on it. It is more effective than traditional engraving for small objects.

In the apparel industry, it is most common to use laser machines to directly engrave customized patterns on materials. It is also applied to heat transfer vinyl, especially thick or stretchable materials. The laser engravers cut quickly and accurately, thus replacing the traditional cutting method.

How much does a laser engraving machine cost?

Laser engraving machines are widely used in various engraving and cutting jobs because of the smooth cutting surface, fast cutting speed and high precision, especially in industries that have higher standards and requirements for cutting speed and accuracy. However, when buying a laser machine, people are likely to be confused as to which laser engraving machine to choose and what the price of the machine is.

It is difficult to give a simple answer as it depends on your needs or what kind of work you want to accomplish? Before starting all projects, you first need to consider the material you want to process and its production volume, and then you determine the specs you desire for the machine, such as the type of laser, wattage, and working area size. Different types of laser engraving machines have different functions and applications. Generally, the greater the wattage and work surface, the higher the cost.

Another thing to consider when buying a laser engraver is the cost of maintenance. The amount of cleaning required for machine maintenance depends on the materials used. Sometimes mirrors or lenses need to be finely cleaned, and the machine may also need to be realigned. Regular maintenance and cleaning help avoid consuming too much time and interrupting the company's production line. There is also the after-sales service, which may incur labor and parts costs when necessary.

Why is a laser engraving machine so expensive?

The price of a laser engraving machine varies widely from one model to the next. There are some low-cost and self-assembled units available at US$100-300, but the limited efficiency and laser power can only handle paper or the surface of wood and plastic. However, there are some high-quality units that cost dozens of times or even more. This massive difference in equipment cost is reflected by the significant difference in machine quality, functionality, and performance.

High-quality laser engravers typically consist of durable components that do not break down easily and powerful lasers that cut through a variety of materials precisely and quickly. High-quality laser engravers use software that is compatible with many programs, making them highly versatile. Finally, it has a comprehensive warranty and service package that protects you from equipment malfunctions and breakdowns (usually lower-cost laser engravers are not provided with warranty and service and eventually given up).

While it may be tempting to buy the most inexpensive laser engraving machine so you can spend the least money on your latest beloved project, perhaps a more expensive machine is a wise investment for you in the long run. Investing more money into a higher-quality unit means longer service life and smaller maintenance costs, both of which will lead to lower overall equipment costs.

How much does a small laser engraver cost?

Small laser engraving machines do not take up much space and therefore have a large market in DIY & hobby users, personalization, and education market. Small laser engraving machines in the market vary in quality and price. The price of laser cutting machine is often determined by the laser brand, laser power, servo motor, laser head and other configurations. Of course, a more affordable system is by default less functional and perhaps less reliable, and the output quality does not always satisfy most people.

One thing to remind you is to consider practical needs rather than price when choosing laser equipment. There are a few factors to determine the suitable laser equipment for you, such as what materials you want to process, what you want the equipment for, and the quality you expect, etc.

What are the types of lasers engraver?

By laser source, the laser engraving machines developed by GCC LaserPro come with CO2 lasers or fiber lasers.

• CO2 lasers

  CO2 lasers are gas lasers that emit infrared radiation and the most common and widely used laser sources with a wavelength of about 10.6 μm (infrared), which is currently the highest power laser in the world. High-power CO2 laser engraving machines are usually used for industrial applications, while low-power ones are used for commodity processing and engraving.

• Fiber lasers

  With a wavelength of 1,060 nm and a smaller focal length, fiber lasers are about ten times more intense than CO2 lasers. They are suitable for metal processing and widely used for identification and equipment traceability, such as the numbering or marking of metal parts; in addition, they are also commonly used in industrial technology for equipment cleaning, such as removing rust, paint stains, oxides, etc.

Laser engravers can also be distinguished into X-Y table and Galvo laser systems by processing structure; the main difference between the two is how the laser beam moves for engraving and cutting.

• X-Y table

  The laser beam is reflected by a series of fixed mirrors, directed through a focusing lens, and projected vertically from the laser head on the surface of the material. The laser head cooperates with the slide rail of the X and Y axes and directly moves for processing. The maximum working areas for X-Y table are defined by the size of the machines; i.e., the larger the machine, the larger the working area. In addition, the X-Y table can deal with thick materials.

• Galvo laser systems

  The laser beam is rapidly moved back and forth by two reflected mirrors driven by the constant vibrations of a motor, and the beam is irradiated on the processed object with high speed, high precision, and repeatability. The size of the working area is determined by the reflection angle and focal length of the optical element and is usually limited to a working area of up to 300 mm x 300 mm.

How long do laser engravers last?

There is no actual data on how long a laser engraving machine can last, but it is certain that regular and diligent maintenance of the machine as recommended in the user manual will extend the service life of the machine. This not only keeps your laser engraving machine up and running, but also saves you the cost and time of repairing the machine.

Check this article "The Suggestions for Laser Machine Maintenance", which provides 5 basic maintenance tips below to ensure stable and reliable high-quality output and extend the life of your machine:

• 1. Cleaning the Worktable and Motion System

• 2. Lubrication of the X/Y Rail System

• 3. Cleaning the Mirrors

• 4. Cleaning the Focal Lens

• 5. Cleaning the Exhaust Duct

What is fiber laser engraver?

Fiber laser and CO2 laser both project high energy beam on object, and the difference lies mainly in the wavelength of the laser source. Metals absorb the wavelength of fiber laser pretty well, and that makes fiber lasers suitable for metal processing. The working area of most fiber lasers is relatively limited. For this particularly, GCC LaserPro developed a full table size production engraver, which yields spectacular engraving results thanks to the design of the X-Y table.

In addition to S290LS, the S400 and Spirit GLS Hybrid which accommodate concurrently CO2 and fiber dual laser sources produce excellent output quality and allow for a wide range of materials to be processed. No matter it is a font or graphic design, a mark on a plastic surface, or a barcode on the metal tool, you will be satisfied with all the results that come from them.

How does fiber laser engraver technology work?

Fiber lasers use rare-earth-doped fiber as an active gain medium to produce short pulses with high peak power. Fiber laser engraving with high peak power vaporizes material easily to make a clear and visible engraving on the material. Fiber laser with short pulse makes heat-affected zone smaller to reduce over-burning at the edge area of materials during engraving.

What materials can a fiber laser engraver?

You can use fiber laser engravers on a wide range of metals, including stainless steel, copper, iron, nickel, aluminum, brass, and many more. Some materials, like plastics (ABS, PBT, Silicon, ABS, PS), synthetic leathers and carbon fiber, are also suitable for fiber laser engraving.

Can a fiber laser engraver work on glass or wood?
