Many fiber laser engraver customers ask us about machine life, productivity, consumables, and how much material the fiber can mark or engrave on. Many of them already know that UV laser can engrave almost any material, but at the same time they also know that UV laser is a technology that is three times more expensive than fiber laser technology. Also, when you want to engrave metal, UV laser technology works The speed will be slower.
What material can we mark/engrave with fiber laser marking machine
Aluminum is one of the most common marking substrates and is used in many industries. Generally, the lighter the marking strength, the whiter the aluminum will be. Aluminum looks good when anodized, but the white markings don't work with bare and cast aluminum. More intense laser settings are available in dark grey or charcoal.
The Ortur range of engravers are all capable of marking on aluminum, and the ideal system for your application depends on your laser marking requirements. The Ortur Laser Master 3 is the best Ortur brand engraver out there.
2. Brass and Copper
Brass and copper have high thermal conductivity and heat transfer properties and are commonly used in wiring, printed circuit boards, and pressurized flow meters. Their thermal properties are ideal for metal laser marking systems because heat can dissipate quickly. This reduces the effect of the laser on the structural integrity of the material.
The best marking technique depends on the brass or copper finish. The smooth surface provides a soft polished marking effect, but can also be annealed, etched or engraved. A granular finish offers little chance of polishing. Etching or engraving is best done to provide human and machine readability.
3. Tungsten and Carbides
Tungsten and carbide are two of the hardest metals on earth and are widely used in tooling and cutting applications. Another popular part of these substrates are men's wedding rings. Tungsten and carbide are receptive metals for laser marking and laser engraving.
The xTool D1 Pro is capable of marking on tungsten and carbide with very fine engraving, the ideal system for your application depends on your marking requirements. Because these metals are very hard, etching or engraving is generally not recommended.
4. Non-semiconductor Ceramics
Non-semiconductor ceramics come in many shapes and forms. Some are very soft, others are hard, offering a variety of options. In general, ceramics are a difficult substrate to laser mark because they generally do not absorb much laser light or wavelengths.
Chrome plating offers a stylish and sophisticated finish that usually requires minimal laser intensity to remove or penetrate the plating. Care must be taken to ensure that the marking occurs only on the surface and does not affect the chrome.
6. Painted Metal
There are many types of coatings used to harden or protect metals from corrosive elements. Some coatings, like powder coat, are thicker and require more intense laser settings to remove completely. Other coatings, such as black oxide, are thin and serve only to protect the surface. These are easier to ablate and will provide a nice contrasting mark.
7. Glass Fiber and Carbon Fiber
Fiber-based materials such as fiberglass may be limited. Because they consist of a single fiber, the structural integrity can be destroyed by the laser, resulting in fuzzy marks that cannot be scanned.
Carbon fiber is easier to mark because the laser generally does not threaten the integrity of the material. However, due to the composition and color of the carbon, the resulting laser marks are always black, which limits contrast and readability.
And there is a laser engraving machine that exists for marking, LaserPecker 2 will definitely make your eyes shine, the engraving speed of 36000mm/min, you can finish the work in a blink of an eye, making you feel that laser engraving is so simple.
Nickel is usually used as a coating. It can be forged or used as the base metal for some parts, but is generally considered too soft for industrial use. Plating is often used to protect parts from corrosive elements. Care must be taken to prevent it from being punctured or damaged, which would expose the underlying metal surface.
9. Plastics and Polymers
Plastics and polymers are by far the most widespread and variable materials for laser marking. There are so many different chemical compositions that you cannot easily categorize them. Some generalizations can be made based on markers and how they appear, but there are always exceptions. We recommend testing markers to ensure the best results. A good example of material variability is delrin (AKA acetal). The black delrin is easy to mark and offers a striking white contrast to the black plastic. Black delrin is indeed the ideal plastic to demonstrate the capabilities of a laser marking system. However, natural delrin is white and will not be marked with any laser at all. Even the most powerful laser marking systems will not mark this material.
The most common technique in plastic and polymer marking is discoloration. This type of marking uses the energy of a laser beam to alter the molecular structure of the workpiece, thereby changing the color of the substrate without damaging the surface. Some plastics and polymers can be slightly etched or engraved, but consistency is always an issue.
Rubber is an ideal substrate for engraving or etching because it is soft and highly absorbent. However, laser marked rubber does not provide contrast. Tires and handlebars are a few examples of marking on rubber.
11. Semiconductor Industry
A wide range of materials are used in the semiconductor industry. You have ceramics, printed circuit boards, epoxy/mold and silicon ICs and more. When marking on semiconductor substrates, the biggest key is accuracy and depth control. Accuracy is required to ensure proper placement and readability of marks, which are typically less than 1mm and read by vision systems. Deep control limits the amount and heat transfer of particulate dust to protect sensitive electronic equipment or components.
12. Silver and Gold
Precious metals like silver and gold are very soft. Silver is a difficult material to mark because it oxidizes and tarnishes easily. Gold is easy to mark and requires very little power to obtain a good contrast anneal.
13. Stainless Steel
Besides aluminium, stainless steel is the most common marking substrate we see at RMI Laser. It is used in almost every industry. There are several types of steel, each with a different carbon content, hardness and finish. Part geometry and size also vary widely, but all allow for a variety of marking techniques.
This lightweight superalloy is heavily used in medical and aerospace applications due to its strength, durability and limited mass. Industries using this material have a heavy responsibility to ensure that the marking being performed is safe and undamaged.
