And which ventilation is compatible?

Yes, it is possible to engrave on a dog tag, particularly in stainless steel, as well as on certain plastics such as Biothane. Laser engraving is well suited to these materials for personalising medals with text or illustrations.

As far as ventilation is concerned, we recommend that you use the machine in a well-ventilated area or with suitable ventilation, as laser engraving can produce fumes and vapours depending on the material engraved. Ventilation or an extraction system is recommended to guarantee the safety and quality of the engraving. Using the machine without ventilation is not recommended for health and safety reasons.
