When laser engraving wood, plastics and rubber, the material will produce dust inside the laser machine. If this dust is not removed from the machining surface and the lenses, it can lead to undesirable processing results such as discolouration, burnt debris or distortions. In this guide we give you our top 5 tips for avoiding dust during laser engraving, in order to ensure consistently clean and accurate laser engraving results.
The following sections elaborate on these points.
Proper maintenance and servicing is essential for achieving a consistently high quality laser engraving result and a long service life for your laser machine. In just a few steps you can ensure that your laser is well maintained.
1x per day: | Check the work space and, if necessary, clean it. |
1x per day: | Inspect the mirror and lens on the machining head. They should always be free from dust and smut, so as not to be damaged. follow our guide for more information about cleaning lenses. |
1x per day: | Check that all ventilation slots are free from contamination. This ensures a continuous flow of extracted air. |
1x per week: | Check all optical and mechanical components for debris and clean if required. |
A proper exhaust system is an important component in a clean work area and achieving high-quality laser engraving results. During laser engraving the dust is immediately removed alongside contamination from the work surface.
It is important to regularly monitor the filter and the activated carbon inserts to ensure consistent, efficient extraction. Pay attention to the display on the extraction system as the operating status and upcoming maintenance are displayed on it.
Details of all display messages can be found in the operating manual of your extraction system. If you have any questions, we are happy to help you. Please contact us for more information.
The best laser engraving and cutting results are achieved by focusing the extraction specifically on the point of the laser processing. This can be done by covering the unused part of the rear exhaust vent.
If you use a vacuum table, you should also cover the vacant suction holes. This results in better suction for thin workpieces, such as engraving laminate boards, so they lie flat on the work table. By doing this you achieve a uniform distance between the lens and workpiece, resulting in a homogeneous processing of the surface.
To cover the rear exhaust vents, we recommend using magnetic strips or masking tape. For the table, materials such as paper, cardboard or laminate boards are sufficient as cover.
Reversing the laser engraving direction to “bottom to top” is very helpful for all materials in which the dust produced by engraving could compromised the finished workpiece. This technique is especially useful when engraving laminates, as well as woods or acrylics.
By changing the laser engraving direction, the engraving dust does not settle on the still warm, freshly engraved surface. Instead, the dust - depending on the laser machine model - is extracted by the head extractor or by the extractor on the rear wall of the machining area. As a result, the unprocessed part of the material is always engraved so that no dust is deposited on the warmed-up engraved surface.
The changed engraving direction also helps the user to be able to better see the material or the engraving result. By moving backwards, the axis does not obscure the view throughout the job.
Stamp engravings are generally made with the standard engraving direction “from top to bottom”. The engraving dust is heavier than with other materials and stays on the workpiece instead of swirling upwards with the suction of the extracted airflow.
