QIDI Chamber Heater for Max4 Series - 200W PTC Forced Convection Heating Module for X-Max 4 & X-Plus 4

3D printer chamber heater delivering 200W of forced-convection warmth to bring enclosed build volumes up to 65°C quickly and evenly. The QIDI Chamber Heater for the Max4 Series is the single most effective upgrade for reducing warping and improving layer adhesion when printing ABS, ASA, PC, Nylon, PEEK, or PEI on your QIDI X-Max 4 or X-Plus 4.

Advantages

By maintaining a stable, elevated ambient temperature inside the printer enclosure, this heater minimises thermal stress during cooling. Parts stay flat on the build plate, corners remain sharp, and large models print without delamination. The integrated high-efficiency centrifugal fan distributes heat uniformly, eliminating cold spots that cause inconsistent mechanical properties. Because the ceramic PTC element self-regulates, the system is inherently safe and energy-efficient, drawing only the power needed to hold the target temperature.

Suitable for

• QIDI TECH X-Max 4 and X-Plus 4 3D printers
• Engineers and advanced makers printing with ABS, ASA, polycarbonate, nylon, PEEK, or PEI
• Large-format models prone to warping or layer separation
• Users who demand repeatable, production-grade results from temperature-sensitive filaments

Recommendations

For best results, preheat the chamber for 10–15 minutes before starting a print and keep the door closed during operation. Use with an enclosure thermometer to verify stable temperatures. This heater is a direct replacement for the original QIDI chamber heater and requires no firmware changes.
