Home laser engravers have become affordable, and they're a fantastic way to personalise gifts. But a laser is a serious tool. Here's what to know before you buy one.
Diode vs CO2
- Diode lasers are compact and affordable, and the most common home choice. They're great on timber, leather, slate and coated metal, and they can cut thin plywood. They struggle with clear acrylic and glass.
- CO2 lasers are bigger and more expensive. They cut thicker material faster and handle clear acrylic and glass engraving well.
What the watts mean
Many listings advertise the input power. What matters is the optical output. Roughly: 5 W is good for engraving, 10 W engraves quickly and cuts thin ply, and 20 W and above cuts thicker timber in fewer passes.
Safety is not optional
Laser light can permanently damage eyes, even from reflections, and burning material makes smoke and fumes. Every home laser setup needs the following.
- Eye protection rated for your laser's wavelength. Most diodes are around 445–455 nm, and goggles must be rated for it. The tinted lids that come with cheap lasers are often not enough.
- Ventilation or fume extraction to the outdoors.
- A fire extinguisher within reach, and never leave a laser running unattended.
- Never laser PVC or vinyl, because it releases chlorine gas that harms you and corrodes the machine.
