El CNC laser engraving and cutting It is a widely used technology in the industry, since it allows fast and very precise work. You can find this type of machinery both for makers, as well as for small companies such as carpentry workshops, metal workshops, etc., and even in larger companies for the production of parts on a larger scale.
As we discussed in the previous article on cutting, the laser beam focused on the surface of the piece will be capable of marking, burning, or evaporating material, depending on the type of material. That way you can work.
Between the advantages of this type of laser process are:
- With a single machine you can engrave and cut
- Great precision in cuts and engravings
- Ability to replicate many identical parts
- Can create complex layouts
- Reduce the number of scrap parts
- The tool does not require maintenance (sharpening, tool replacement,...)
- No debris such as chips or dust is generated
- Very clean cuts, without burrs, which will reduce revision and post-processing time.
- The piece does not need to be held during the process, since at no time is it touched
- It can be a profitable technology
Not all are advantages, the disadvantages of this type of CNC machine is:
- May burn some materials, such as certain woods, if exposure time is not minimized
- Cuts in woods that are too wet or with resins are not as clean
- The laser is a dangerous technology, so protective glasses should be used if the machine does not have a protective barrier to filter the emitted radiation.
- The cutting speed is usually not the best compared to other CNC machines intended for cutting
- Limitations on the thicknesses you can cut
- Not suitable for certain transparent materials
Types of laser CNC machines
As for types of cnc engraving We have several ways to catalog these machines. One of them is according to the technologies or laser sources, and another can be according to the material they can work with, although the vast majority accept multiple materials without changes.
Types of CNC laser engraver according to technology
Laser diode (solid state laser)
One of the most widespread CNC engraving machines is the one that uses laser diodes. They are cheap and are usually used for DIY or small workshops or freelancers dedicated to engraving. This type of machine differs from the rest in that the source of the laser beam is obtained from a semiconductor device, an LED similar to IR or light, but that can emit a specific wavelength.
They have some and advantages Compared to other technologies:
- They are small and light.
- They have a fairly long lifespan, estimated at about 8000 hours.
- Power can be adjusted while running, which can allow you to cut or engrave only, and even create multi-grayscale designs (PWM).
- The laser will always point at the work surface, so no special protective equipment is needed, just a pair of goggles if you don't have a protective case with a filter.
However, they also have their disadvantages and limitations:
- One of the main ones is the output power of the laser. Laser diodes are typically around 8W, some can reach up to 40W using small pulses, but they cannot maintain that maximum power consistently. Therefore, this may limit the materials you can work with and the thicknesses you can cut.
- Nor will they be able to work with transparent or translucent materials, nor if it is a highly reflective material. Some of the most difficult materials to be engraved by laser diode are some shiny bare metals, glass, etc. Some of them would need masking material (or anodized metals), but this can be expensive.
- They usually need more time than other more powerful lasers.
On the other hand, machines with higher power output, for professional or industrial use, are usually based on CO2 lasers. These have the advantage of reaching higher powers, between 40W and 100W, enough power to cut thicknesses greater than those allowed by diode technology. However, these lasers are still somewhat limited in metal engraving as they often require a coating material to make it less of a reflective surface.
One of the main disadvantages of CO2 lasers is their size. The tube is usually big size and also fragile. On the other hand, the laser is visible to the naked eye, so you will need the machine to be completely closed. In addition to that, there are other considerations to keep in mind:
- The CO2 laser tube is usually placed at the rear of the machine in a stationary way, using mirrors to direct the laser beam to the part. This results in the mirrors having to be oriented correctly, which can be tedious in some cases where it doesn't adjust automatically.
- They also need water cooling to prevent the tube from overheating, as it tends to get quite hot during the process. This adds complexity, weight and bulk to the machine.
Despite everything, CO2 laser CNC engraving is usually very versatile due to its power and speed for small-scale production. Of course, it cannot generate gray scale effects in the recorded images, since it does not allow control or adjustment of the beam while it works.
Finally, another of the technologies for CNC engraving is the fiber laser. this is much newer than the two previous technologies, but it is increasingly better considered given its small focal diameter to increase the intensity of the beam up to 100 times with respect to CO2. Thanks to that, they can easily engrave and cut metals and other hard materials.
In this case, the useful life is even higher than the diode, so they will be more reliable machines. The useful life usually exceeds 25000 hours. The disadvantage is that it is a more expensive technology at the moment, so it is more oriented to industrial or professional use. They are expensive machines for the average user who needs them for DIY.
The technology is simply based on a tube where the laser beam is generated, which comes from a diode and will be conducted through a fiber optic cable doped with elements such as ytterbium or neodymium, amplifying the power of the beam.
Between the advantages of the fiber laser with respect to the diode and the CO2 are:
- Much longer shelf life
- Smaller laser beam diameter, concentrating power to improve cutting capabilities
- Capable of recording texts and drawings in high resolution
- The laser beam is more stable
- Requires less investment in maintenance
- They are very versatile due to the number of materials they can engrave and cut (steel, stainless steel, aluminum, titanium, brass, copper, silver, gold, hardened metals, iron, etc.).
- Fiber laser tubes are more compact than CO2 laser tubes of equivalent power
However, as is evident, it also has its disadvantages:
- Higher equipment cost
- Inability to process organic materials
These machines can be used for many applications: labeling, manufacturing or personalizing jewelry and other objects, engraving logos, text, barcodes and QR codes, serial numbers, traceability codes, engraving tools, cutting parts and marking, manufacturing electronic components, welding, cleaning of metals, and more.
Types of CNC laser engraver according to the material
laser engraving on wood
CNC laser engraving machines that support woodworking can mark with a lots of types of wood , both soft and hard, as well as MDF panels, plywood, etc. Not all woods work as well with this type of marking. It is best to work with woods with low humidity, with as little beta as possible, and with as little resin or sap as possible (resin causes darker burns).
Best to work are:
- Cerezo: It is very easy to work and cut. However, you have to consider that over time it can darken and take on a more reddish brown color.
- Alder: it is another wood that also darkens over time, but it is one of the best for working with the laser, since its lighter color leaves dark marks during engraving and with good contrast.
- hard maple: it is a whitish wood, somewhat yellowish, and excellent for laser engraving due to its finishes. However, it is somewhat more complicated to work with since it is denser.
- Linden: This wood is very soft and light. It works very easy and fast.
- ochroma: a type of softwood widely used to create rafts. It has a somewhat reddish hue, can be tinted well, and can be engraved well. Its main flaw is that it can be susceptible to nicks and dents because it is not very hard.
- Plywood: You can also work with a laser, but the results will depend on the quality of the plywood. However, for cuts it is a great choice, especially birch and bamboo.
- Wood fiber boards: HDF, MDF, etc. are not suitable. These are made from cellulose and mixed with resins and compressed. That does not make them the best material to use with lasers because of the glues or resins used. However, MDF panels could be used for cutting, although some dark areas or burns will be generated.
For wood cutting or engraving some steps should be taken. adjustments to adapt well to this type of materials. Also, before proceeding with the engraving or cutting you should prepare the material well, and have everything suitable to start, such as dust filters, protection elements, etc.
metal laser engraving
Engraving laser on metal It is also widely used in industry, given the versatility of metals. In this case, CO2 and fiber lasers are usually used. The advantage of CO2 is that the mark is produced on the surface of the metal, without removing part of this metal, without interfering with the impact tolerance or resistance of the piece. Also, coated metals such as anodized aluminum or painted brass, plated, powder coated, etc., will not require pre-treatment.
For bare metals it is better to use fiber lasers. They are ideal for bare aluminum, brass, copper, nickel plated metals, stainless steel and more. What you do have to keep in mind is that this type of laser will create gray shadows and not black on aluminum or titanium. Depending on the alloys the tone will change.
Some of the most used metals for CNC they are:
- Anodized aluminum
- Precious metals
- Sheet metal up to 0.5 mm (brass, aluminium, copper, precious metals…)
- Stainless steel
- painted metal
laser engraving on plastic
Another of the most important engravings after wood and metal is the plastic. It is one of the most widespread materials and used for its properties and large number of applications. Plastics can be lasered, though not all or all types of lasers, as they could melt or burn. Most plastics tolerate CNC laser engraving, marking and cutting well, but the most commonly used are:
- Acrylics/PMMA, such as Plexiglas®
- Polyamide or PA
- Polycarbonate or PC up to 0.5mm
- Polyoxymethylene or POM such as Derlin®
- Polypropylene or PP
- Polyphenylene sulfide or PPS
- Polystyrene or PS
- Polyurethane or PUR
- PVC-free foam
laser engraving on glass
El glass or crystal engraving it is also possible by laser, although not all lasers can achieve it, not even in mirrors. However, there are machines in which these materials can be used. On the other hand, the advantages of using lasers to engrave mirrors, glasses, stained glass windows, jugs, bottles, etc., are:
- Custom design possibilities and complex drawings
- Flexibility for modifications even in small batches
jewelry laser engraving
Of course, another of the great uses of CNC laser engraving machines is the personalization of jewelery and costume jewelery, in addition to keyring plates, etc. In this sense, you can work from stainless steel, chrome, sheets, anodized metals, and even noble metals such as silver and gold.
Finally, they can also be used many other materials to engrave them using the CNC, such as:
As you know, CNC laser engraving machines are even used for the inscriptions they make on the PCBs or chips in the electronics sector...
