This chamber-temperature module has already been validated on the P1 and has now been ported to the Ailaku model, where it is secured using high-temperature-resistant 3M double-sided tape. The results are outstanding: temperature is uniformly distributed throughout the chamber, and there is no risk of overheated airflows damaging the printer.
It takes only 10 minutes to raise the temperature from 15°C to 55°C, with uniform heating across the entire chamber and no hotspots or thermal buildup.

This project is intended solely for exchange and learning purposes; commercial use is strictly prohibited, and operation without professional electrical expertise is forbidden!!!

When printing with PETG, the temperature setting must never exceed 55°C!!

When using ABS, the temperature must never exceed 65°C!
