Laser Marking FAQ
-
How do I choose the best laser?
There is no one-size-fits-all laser; the material being marked determines the best laser to use. For metals, fiber lasers are the best choice, while for wood or organic materials, CO2 lasers excel.
-
What is laser marking?
Laser marking is a process that uses focused laser beams to create permanent marks on various materials. It typically involves two main laser types: 1064 nm lasers (such as fiber lasers), which are ideal for metals and some plastics, and 10,600 nm CO2 lasers, which work best on wood and organic materials. Fiber lasers are favored for their efficiency and durability, while CO2 lasers are optimal for marking non-metallic surfaces.
-
What determines the price of a steered beam laser marking system?
The price of a steered beam laser marking system is determined by the cost of specialized components such as the laser source, optical system (including galvanometer scanheads and lenses), computerized control systems, and proper housing, with individual components like a 20-watt laser module alone costing over $12,000. Additional factors include system assembly, calibration, and long-term support, as well as the choice between high-quality components versus cheaper alternatives or refurbished YAG systems, which can reduce costs but may compromise performance or reliability.
-
What makes fiber lasers different from YAG lasers?
Fiber lasers and YAG lasers both emit light at 1.06 microns, but they differ significantly in efficiency and maintenance. YAG lasers are power-hungry, requiring 4-5 kW to produce 20 watts of laser output, with most energy wasted as heat that needs external cooling. In contrast, fiber lasers generate the same output using only 200 watts, with heat managed by built-in fans. Fiber lasers are also more compact, low-maintenance, and free from consumables, unlike the larger, maintenance-intensive YAG systems.
-
Is there really no laser maintenance with fiber systems?
There are no user serviceable parts and there is absolutely no laser maintenance or consumables associated with fiber lasers. They are much smaller than YAG lasers and enjoy an extremely long lifetime without power degradation.
-
How fast can I laser mark a part?
The speed of laser marking a part depends on several factors, including the number of vector lines the laser draws (as text, graphics, or barcodes are made of individual lines), how fast the laser traces those lines, and the material being marked. For example, marking "Jimani" in bold Arial on anodized aluminum takes around 2-3 seconds, while using a single-line "stick" font reduces the time to 300 ms. However, marking the same bold text on a steel plate to a depth of 0.010" can take around 25 seconds. Total cycle time also includes part placement and removal.
-
What is the cost to job shop laser mark my parts?
The cost to laser mark parts at a job shop typically ranges between $60 to $100 per hour. The price per part depends on how many can be processed within that time, which is influenced by the complexity of the mark and the handling involved. For example, at a shop rate of $80 per hour, marking a simple logo on small anodized aluminum parts (arriving in bulk) might cost around $0.27 per part, often marked up to $0.30. Additional charges may apply for setup, programming, or handling if parts require special packaging. Whether outsourcing makes sense depends on factors like production volume, internal capabilities, and shipping logistics.
-
What is the cost of a laser system?
The cost of a laser system depends on its components and features, such as laser modules, scanheads, lenses, and control electronics. For example, a high-quality 20-watt fiber laser system with a versatile Z-axis workstation is typically around $45,000. Additional factors like motion systems or enclosures can increase the price.
-
What is laser marking and is it suitable for my products?
Laser marking involves using a focused laser beam to create permanent markings on various materials, such as text, images, or codes. The suitability of laser marking for your products depends on the materials you're working with, as different lasers are optimized for specific materials (e.g., CO2 lasers for wood and YAG or fiber lasers for metals). This technology offers precision and durability, making it an excellent choice for branding, identification, and traceability.

Why does Jimani Uses Prolase Laser marking software?
Jimani uses Prolase laser marking software primarily for its exceptional customer support and responsiveness. The developers, American Laserware, specialize in laser marking software, ensuring they address any issues swiftly. For instance, when a customer faced problems with "ghost" marks due to a fiber laser's delay, the Prolase team implemented a solution within hours. This level of support is crucial for Jimani, as it enhances reliability and efficiency in their laser marking operations.
