Buying Guide to 3D Laser Marking Machines

The article provides a purchasing guide for 3D laser marking machines, and explains seven key indicators that must be tested on-site, including marking accuracy, speed, and material compatibility.Through the use of actual testing methods, it helps users select equipment with a high ratio of performance to price, avoiding the problem of false parameter claims, and ensuring that the equipment meets production requirements.

Why is testing necessary?

When choosing a 3D laser marking machine, many users are easily "fooled" by manufacturers 'specifications.No matter how beautiful the specifications are, the actual performance may be a lot less.For example, it is not uncommon for a machine with an advertised precision of 0.01 mm to produce a sample with a fuzzy edge.Therefore, we have to test them ourselves. Below are seven indicators that you should not skip!

The precision and clarity of the marking.

The samples were stamped on the spot.

Don't just look at the "micron-level accuracy" on the brochure. Bring along some of the materials you usually work with (like metal plaques or plastic parts) and have the manufacturer engrave them on the spot.The key is to focus on the details of complex patterns, such as whether the strokes of small characters are connected, and whether the curved lines are smooth.If it can't even print your logo clearly, then you can just forget about it.

Comparing different focal lengths.

The operator can adjust the focal distance to produce different patterns.High-quality equipment should maintain consistent clarity at different heights, while lower-end models may suffer from blurry edges or uneven energy distribution.

Actual work speed.

Don't be lazy.

The figures the manufacturers give for "XX items marked per minute" are usually under ideal conditions.You can use a stopwatch to measure the time from the moment you press the button until the needle is back in its original position.Remember to test both shallow and deep engraving modes. Deep engraving is generally at least 30 % slower.

Continuous operation stability.

The machine is operated for more than an hour to observe whether the speed drops.Some machines have a fast start-up, but as they heat up and the laser power declines, they get slower and slower. These machines have a high maintenance cost.

Materials adaptability.

Bring your own special materials.

If you need to process special materials such as anodized aluminum or ceramic, don't take the phrase "supports multiple materials" at face value.The key point is to see whether the color is even.For example, if you try to put white lettering on black anodized aluminum, a low-quality machine might result in yellowing or uneven coloring.

Sensitivity of energy regulation.

Let the technicians show how to quickly switch between the parameters of different materials.A good machine will have a memory function, so that you can switch with one button between the settings for copper, stainless steel, or glass, rather than having to manually adjust it for half an hour each time.

The seven criteria are: 1) laser stability; 2) ease of use; 3) after-sales service; 4) cost-effectiveness; 5) accuracy; 6) speed; and 7) reliability.
