When printing large or high-strength engineering materials (e.g., ABS), uneven cooling causes internal thermal stress, leading to warping, delamination, or cracking.

In low-temperature environments, excessive temperature differences between molten and solidified layers weaken adhesion. A controlled heated chamber maintains optimal layer temperature, enhancing molecular diffusion for stronger interlayer bonding.

The heated chamber reduces ambient humidity’s effect on hygroscopic materials (e.g., nylon), preventing bubbles or strength loss caused by moisture absorption during printing.

For industrial production, chamber temperature stability is critical for part-to-part uniformity. Active temperature control eliminates environmental variability, guaranteeing reliable repeatability.
