If Your Laser Marking Quality Is Declining, It May Be Time to Replace One of These Four Consumables

If your laser engraver suddenly starts producing blurry results with uneven depth, then it could be time to replace the consumables. In this article we look at the four core consumable parts of a laser engraver--the lens, laser tube, galvanometer, and filter system--and explain how to determine when it's time to replace them.

Why do aging consumables affect the quality of printing?

Lasers are like cars. After running for a long time, parts will naturally wear down.If you notice that the markings are blurred, the lines are broken, or there are even burn marks, don't adjust the settings right away. First check the four key consumables. They may be quietly holding you back.

Dirty or damaged lenses.

It is the most easily overlooked detail.

If the surfaces of the focusing lens and the beam expander get oily or dusty, it's like wearing dirty glasses and the laser energy will be scattered.If the foggy spots are still there after three cleanings or if the lenses have cracks, it's time to change them.

The energy of the laser decreases.

The "hidden killer" of consumables.

After using a CO2 laser for 8000 hours, the output power may decline by more than 15 %.If you need to repeatedly turn up the power to achieve the same depth, it means that the laser tube has had its day.

The mirror's performance deteriorated.

The mechanical hand is moving more slowly.

Wear and tear on the bearing of a scanning mirror can cause positioning errors, leading to distorted images or failure to read QR codes.If you feel the mirror motor is stuck or hear a squeaking sound, replace the entire scanner head.

The filtration system was clogged.

Poor ventilation leads to a chain reaction.

The air filters in the smoke exhaust ducts hadn't been changed in three months?Remove the filter and hold it up to the light. If less than 50 % of the area is transparent, replace the filter and check that the fan is operating at the correct speed.

Small tips for daily maintenance.

Wipe lenses with alcohol once a week.

Every 200 hours of operation, the rails are lubricated with a special grease.

During the rainy season, maintain environmental humidity at or below 60 % to prevent the lenses from fogging.

Taking care of these details can extend the life of consumables by over 30 %.If you're still not sure which part to change, take a picture of the screen and the model number and send it to us, and we'll give you a free diagnosis.
