According to court documents from San Fransisco, the parents of Calvin Yu, who died in a fire caused by a 3D printer in 2020, are suing both the 3D printer manufacturer, Tronxy 3D, and Alibaba. The fire occurred when a Tronxy X5SA 24V 3D printer overheated and caused a fire when it ignited the couch. This caused fatal injuries in Calvin Yu. Now his parents are seeking damages from the two companies under a number of complaints including negligence and product liabilities concerning printer defects and failure to warn.
You have probably at least heard already of Alibaba, the multinational technology company specializes in e-commerce, retail, internet and technology, among other things. Most importantly in the case of this lawsuit, the company also own AliExpress, an online retail service based in China, similar to Amazon and popular for its worldwide free shipping and low prices. Meanwhile, Tronxy 3D is a popular Chinese manufacturer of 3D printers including DIY options. They focus primarily on FDM, LCD and ceramic printers. In this case, the fire was caused by a Tronxy X5SA 3D printer, one of the more popular models which is available from only $280.00 and which was bought from AliExpress.

The Yus’ Case for Damages Against Tronxy and Alibaba
In the court documents, it was noted that the San Fransisco Fire Department did find that the direct cause of the fire was the 3D printer which was plugged into an outlet when it overheated. They also concluded that Calvin Yu’s death was a result of thermal injuries caused by the supposedly defective 3D printer. Hoi Kwong Yu and Janice Yu are now seeking damages as they claim that 3D printer was being used as intended and thus was defective and malfunctioned. They also place the blame on Alibaba and Tronxy for not sufficiently warning them of potential dangers or properly checking the machine. The documents note that, “[The] Defendants…had a duty to warn Decedent Calvin Yu about the defects in, and the dangers associated with, use of the Tronxy X5SA 24V 3D printer of which they were aware, or in the exercise of ordinary care, should have been aware, at the time the printer left the Defendants’ control.”
