Yes, a laser engraver needs to be vented.
The exhaust system is important for removing fumes and particles generated during the laser engraving process. Without proper ventilation, the operator and people nearby may inhale harmful particles and chemicals.
Additionally, inadequate ventilation can cause damage to the laser machine. Therefore, it is recommended to install a ventilation system and follow proper safety procedures when using a laser engraver.
By doing so, we can ensure a safe and healthy working environment, as well as extend the lifespan of the equipment.
