I purchased a Creality K1 Max 3D printer from Domirobot through Hepsiburada.com on July 17, 2024. On December 21, 2025—before the expiration of the legally mandated two-year warranty—the device experienced a serious technical failure during a routine automatic calibration process.
Due to a sensor malfunction, the nozzle did not stop as it should have and forcefully crashed into the print bed, causing deep physical damage. Later, while replacing the nozzle and inspecting the unit, I discovered that the impact had caused cracking in the hot-end assembly, which led to filament leakage. These damages are not consistent with normal wear and tear. Rather, they are structural failures caused by a malfunction in the printer’s automatic software and sensor system.
When I contacted Domirobot, they initially persuaded me to delete my first complaint by promising a resolution. However, afterward, they stalled the process by claiming that the device had exceeded 1.5 years of use and that the affected parts were consumables. My printer is 19 months old and still well within the 24-month legal warranty period. The fact that more than 1.5 years have passed does not eliminate the seller’s or manufacturer’s responsibility for a technical defect of this nature.
Because the malfunction occurred during a fully automated software and sensor-controlled process—without any user intervention—I believe this constitutes a hidden defect. The damage to the print bed and hot-end assembly resulted from a system failure, not from user error or ordinary wear.
I am requesting that Domirobot repair this warranty-covered defect and replace the damaged print bed and hot-end assembly at no cost to me. Otherwise, due to the hardship I have experienced before the expiration of my legal warranty period, I will file a formal complaint with the Consumer Arbitration Committee under Turkey’s Consumer Protection Law No. 6502.
