Laser cutters can be dangerous for kids (and even for adults) if they are low quality. Luckily there are a few home laser systems that were created for educational purposes. With kids in mind. one of them is MakeBlock laserBox that features a 40W CO2 laser, a rotary option (to engrave on cylinder-shaped items such as mugs). It has robust safety features in place, such as if you open the lid, the machine pauses the job, and it has an advanced Early Warning System in place to detect unsafe situations and make you aware. Other safe-for-kids devices are the Flux laser series and the Gweike cloud, a fantastic laser cutter for rock bottom pricing.
