The product at the center of the controversy is the Qidi Tech Plus 4, a CoreXY 3D printer. A key feature of the Plus 4 is its large, fully enclosed build volume with an actively heated build chamber capable of reaching temperatures up to 65°C. This feature is critical for printing with engineering-grade materials like ABS and Nylon, which are prone to warping without a consistently hot environment.<ref name="TomsHardware">{{Cite web |last=Bertacchi |first=Denise |date=18 Apr 2025 |title=QIDI Plus4 Review: Bigger is Better |url=https://www.tomshardware.com/3d-printing/qidi-plus4-review |access-date=5 Aug 2025 |website=Tom's Hardware}}</ref> The high-power electrical system required to heat the chamber became the focal point of the subsequent safety concerns.
