3D printers contain heaters and can be a fire risk, particularily on the cheaper end.
Some manufacturers (such as Creality and Anet) also turn off software safety features such as thermal runaway protection (which recognizes when a heater is behaving erratically and turns it off). This is considered a CRUCIAL safety feature and Oliof has put together an incredible resource explaining it here.
Known recurring issues with creality machines include:
- Thermal runnaway protection disabled by default
- Dodgy volt converter
- Poor stress relief on cables causing wear and subsequent fires
- Cheap, crimped fake XT60 connectors (these connectors are designed to be soldered so they release if heated. This is now more of a legacy issue (after overwhelming community outrage Creality fixed this one issue), but there is still old stock being sold).
Some examples of these issues:
- Sparks at USB port
- Fire at volt converter
- Board sparked
- CR6: lots of smoke coming from power supply, appears to be due to a loose screw rattling around inside
- CR6: switch smoking
- Video of one catching fire
- Motherboard with tinned leads, info on why this is an issue
- Cables caught fire
- More cables caught fire
- Ender 3: fake, crimped XT60
- Ender 3: more fake, crimped XT60
- Ender 3: even more fake, crimped XT60
- Ender 3: control box smoking
- Ender 3: nearly burned house down
- CR10s MOSFET fire
- Ender 3: electro-shocks user when touching any metal
The Anet A8 is notorious for having started several major housefires, several examples and discussion.
- Tronxy D01: No Thermal Runnaway Protection
- Anycubic i3 Mega: Burned Connector
