"What exactly you think are hazards in 3D printing? And low-voltage electronics?"
Fire and fumes. Even low voltage can start fire or create some toxic fumes if it melts the wrong stuff and when you have a cold and smell little, you might inhale enough to poison yourself, before you notice.
And I am rather afraid of electricity, than the chainsaw. Because when the chainsaw is running, it is obvious it is dangerous. But a broken electronic component with an open circuit can be hard to spot.
