December 10, 2025 – A critical safety alert has been raised regarding the ELEGOO Centauri Carbon 3D printer, specifically concerning its main power/data cable. An incident report details significant electrical and safety flaws, including cable overheating, strain relief failure, and insulation damage, which could lead to severe hazards such as electric shock or fire.
Product Details
Incident Overview
The ELEGOO Centauri Carbon 3D printer has been identified with a serious design flaw in its main power/data cable. According to an incident report dated October 11, 2025, the cable, which carries up to 60 watts of power, is operating beyond the safe capacity of its internal wiring and strain relief mechanisms.
The core issue stems from the printer’s use of a proprietary connector that combines data and high-current power lines, despite resembling a standard USB-C Power Delivery (PD) setup. This design is reportedly non-compliant with USB-C PD standards. Users, including the individual who filed the report, have observed that the cable frequently overheats, and the strain relief component detaches or fails, leading to insulation fraying or separating near the connector after even light use. These failures result in intermittent power loss, unstable communication between the printer and its power source, and critically, pose a risk of short circuits, electrical arcing, or even electrical fires.
Multiple independent user reports across various platforms corroborate these identical failure modes, indicating a widespread design flaw rather than isolated incidents. The problem appears to be systemic, arising because the cable attempts to push near-maximum current through conductors that are undersized for the load. Additionally, it lacks adequate strain relief and sufficiently temperature-rated insulation. Normal bending or flexing of the cable during operation concentrates heat and stress at the connector, inevitably leading to premature failure.
The printer’s documentation and marketing materials do not disclose that the cable is proprietary and non-compliant with USB-C standards, potentially misleading consumers about its safety and robustness.
Safety Concerns
The identified defects in the ELEGOO Centauri Carbon 3D printer’s power/data cable present several severe safety risks:
- Electric Shock and Fire Risk: Exposed or damaged insulation due to fraying wires can lead to direct contact with live electrical conductors, posing a significant risk of electric shock to users. Furthermore, short circuits from damaged wiring can generate excessive heat, potentially igniting nearby flammable materials and causing an electrical fire.
- Overheating and Material Damage: The cable’s tendency to overheat can melt its own insulation or deform adjacent plastic components of the printer or surrounding surfaces, compromising the printer’s structural integrity and potentially leading to further electrical hazards.
- Electrical Arcing and Power Instability: Frayed wires or broken conductors within the cable can cause electrical arcing, which is a high-temperature electrical discharge that can melt metal, ignite fires, and damage the printer’s internal electronics. Intermittent power loss also disrupts printer operation and can damage ongoing prints.
- Misleading Standards Compliance: The cable’s appearance, which mimics a USB-C PD connector without adhering to its safety standards, can mislead users into believing it is as safe and robust as a certified USB-C PD cable. This false sense of security may lead users to handle the cable without the necessary caution, exacerbating the risks.
- Widespread Impact: Given that multiple independent reports document identical failures, this issue is likely a systemic defect affecting all units, not just a few. This increases the potential number of consumers at risk.
What Consumers Should Do
Given the serious nature of these electrical hazards, consumers who own an ELEGOO Centauri Carbon 3D printer should take immediate action:
- Stop Using Immediately: If you own an ELEGOO Centauri Carbon 3D printer, discontinue use of the product at once, especially if you observe any signs of cable damage, overheating, or intermittent power. Unplug the printer from the power outlet.
- Inspect Your Cable: Carefully inspect the main power/data cable, particularly near the connectors, for any signs of damage. Look for frayed insulation, exposed wires, melted plastic, or signs of overheating (discoloration, warping). Check if the strain relief has detached or failed.
- Do Not Attempt Repairs: Do not attempt to repair the cable yourself, as this could worsen the problem or expose you to further hazards.
- Report the Incident: If you have experienced similar issues, report the incident to the U.S. Consumer Product Safety Commission (CPSC) at SaferProducts.gov. This helps the CPSC gather more data and investigate the scope of the problem.
