The right nozzle for your laser application

The correct nozzle can be the crucial component needed to achieve your perfect laser result. Additionally, the nozzle serves as the main dust protection for the lens. Read below to find out which nozzle best suits your needs.

Selection of nozzles

There are 3 different nozzles to choose from:

Short nozzle with large hole diameter (1/4")

The standard nozzle, a short nozzle that has a large hole diameter (1/4"), may be used with both laser cutting and engraving.
During cutting, the nozzle is mainly used with acrylic since the material doesn't cool down as quickly, making a lovely flame-polished edge.

Laser engraving and cutting with short nozzle

Short nozzle with small hole diameter (1/8")

The short nozzle that has a smaller hole diameter (1/8") is primarily meant for cutting materials that generate too much smoke like wood. Thanks to the small opening, the concentrated airflow goes to the kerf and blows away any smoke or gases that result from cutting.
This nozzle does not work as well when engraving dust intensive materials like plastic or rubber stamps. Engraving dust can quickly settle on the opening of the nozzle and block it, causing a hole to be burnt into the lens.

Long nozzle with small hole diameter (1/8")

Made specifically to be used alongside the 2.5" lens is the long nozzle with a smaller hole diameter (1/8"). This nozzle helps compensate for the bigger focal distance between the 2.5" lens and the laser material. The long nozzle has the same properties as its shorter version.

Copper nozzles for laser cutting with compressed air

When laser cutting using compressed air on the SP500 there are extra copper nozzles that have a hole diameter of 0.07" for short nozzles. Because of the very small diameter, the airflow is even more focused towards the kerf. As a result, you gain the ideal laser cut with materials like thicker wood from around 3/16" thick or polycarbonate.
Depending on the lens you use and the resultant focal distance, these attachments come in four different sizes.
