QIDI Tech Q1 Pro

SaferProducts.gov consumer incident report 20250904-52F7C-2147328085. Severity: Injury, No First Aid or Medical Attention Received. Product: QIDI Tech Q1 Pro (Qidi Q1 Pro 3D printer). Incident: On September 1, 2025, my QIDI Q1 Pro 3D printer (purchased via Amazon, order #[REDACTED], less than 9 months old with light use) experienced a catastrophic overheating failure during a routine print. The printer displayed an error: Heater extruder not heating at expected rate, indicating potential thermal runaway. The silicone boot on the hotend solidified and crumbled to dust, the plastic shroud and sensor mount turned brown from extreme heat, and the printers base burned my hand 20 minutes after being unplugged, posing a severe fire hazard. I was home, preventing a potential fire, but the incident caused a burn injury to my hand. Photos of the damage are available at: initial photos and follow-up. QIDI Tech support has denied any fire risk, offering only a hotend and adapter board replacement, which does not address potential damage to the power supply or wiring. This aligns with reported Q1 Pro overheating and chamber heater issues in user communities (e.g., [REDACTED], [REDACTED], 2024-2025). The printer remains unsafe to operate, and Im pursuing an Amazon A-to-z Guarantee claim due to the sellers inadequate response.
