The primary component of a laser marking system is the laser itself. Typically, fiber lasers are used for clear aligner marking due to their durability and ability to produce high-quality marks. These lasers operate at a wavelength of 1060nm, ideal for engraving most materials used in aligners.
● Power: 30W
● Beam Quality: <1.2 (㎡)
● Operational Lifespan: ≥100,000 hours
● Cooling: Air-cooled
These lasers are efficient and require minimal maintenance, ensuring long-term reliability in high-volume production.
The scanning galvanometer is responsible for directing the laser beam with high precision. It adjusts the beam’s position on the X and Y axes, ensuring that marks are placed at the correct locations on each aligner. The system is capable of achieving a marking speed of ≤70,000 mm/s, which significantly enhances production efficiency.
● Marking Range: 110mm × 110mm
● Repeatability Accuracy: ±0.002mm
This precision is crucial in ensuring that each aligner is marked consistently.
The automatic marking software is an essential part of the system. It is responsible for controlling the marking process, including extracting the content to be marked, such as serial numbers or graphics. The software allows for the easy integration of text and graphics marking, ensuring accurate and consistent results for every aligner.
Before starting the marking process, it's essential to prepare the clear aligners. This involves placing them in a holding tray or conveyor that ensures each aligner is correctly positioned for marking. Ensuring the aligners are properly aligned prevents errors during the engraving process.
Once the aligners are in place, the next step is configuring the software. The software extracts necessary information, such as the aligner serial number, and prepares the system to mark this information onto each aligner. The software allows for customizations, such as adding logos or other unique identifiers.
Proper calibration is key to ensuring that the laser marks align correctly. The Z-axis focus alignment must be calibrated to ensure the laser is precisely focused on the surface of the aligner. The high-speed scanning galvanometer also needs to be set up to ensure the correct positioning of marks on each aligner.
Marking Process | Speed | Accuracy | Time per Mark |
Initial Setup | N/A | N/A | N/A |
Laser Alignment | N/A | ±0.002mm | N/A |
Engraving | ≤70,000 mm/s | ±0.002mm | 3.5 seconds per 4 marks |
Quality Control | N/A | Ensures clear, readable markings | N/A |
Once the aligners are positioned and the system is configured, the first step in the marking process is loading the aligners into the system. This can be done manually or through automated conveyor systems, depending on the scale of production.
After the aligners are loaded, the system automatically adjusts the laser’s focus and alignment to ensure that marks are placed precisely. The system uses the scanning galvanometer to direct the laser beam onto the correct positions.
Now, the system begins engraving the marks onto the aligners. The laser beam moves along the X and Y axes, engraving the content with high-speed precision. This process typically takes 3.5 seconds to mark four individual points on each aligner, significantly speeding up production.
Once the marking is complete, the system performs a final quality check to ensure that the markings are clear and precise. If there are any issues, such as misalignment or unclear marks, the system can automatically adjust to fix the problem.
Laser marking systems offer exceptional precision, ensuring that serial numbers and logos are engraved with clarity, even in fine detail. This clarity is essential for patient identification and product traceability.
With marking speeds of up to 70,000 mm/s, the laser marking system significantly increases production efficiency. Each aligner can be marked in just a few seconds, enabling manufacturers to process large volumes with minimal downtime.
Laser marking eliminates the need for consumables like ink or labels, reducing operational costs. Additionally, the system’s low-maintenance nature ensures that it remains reliable over long production runs, offering great value for the investment.
Tip: Laser marking systems are a one-time investment that can provide significant savings over time by eliminating consumables and reducing labor costs.
Inconsistent markings can be caused by improper calibration or poor focus alignment. To resolve this, the system should be recalibrated, ensuring the laser is accurately focused and aligned with the clear aligners.
Misalignment is often due to an issue with the scanning galvanometer or improper tray placement. Recalibrating the X and Y-axis alignment can resolve this issue.
If the system experiences software or hardware malfunctions, troubleshooting steps such as restarting the system or checking the software configuration should be followed. In some cases, hardware components may need to be replaced if they have reached the end of their operational lifespan.
