The qidi max4 build plate is a precision-engineered dual-sided PEI upgrade, designed exclusively for the qidi max4 3d printer. Measuring 390x390mm, it provides a perfect fit for the printer's large build volume, aligning flawlessly with the qidi max4 nozzle movement path – no trimming or adjustment required. This qidi max4 3d printer build plate features a premium matte PEI coating on both sides, allowing you to flip the plate for extended use. It delivers excellent first-layer adhesion for a wide range of filaments, including PLA, PETG, ABS, and TPU. When paired with the qidi max4 combo, the plate works seamlessly, ensuring consistent print quality across multiple materials. Print removal is simple: once the bed cools, parts self-release, or you can flex the spring steel base to pop prints off without tools or damage. The PEI surface is highly durable, lasting hundreds of prints with proper care. Avoid abrasive filaments (e.g., carbon fiber) on the bare PEI, and clean with isopropyl alcohol for best results. Unlike single-sided or glass plates, this dual-sided qidi max4 build plate gives you twice the lifespan, while the matte finish hides bottom layer lines and reduces warping. While the size may fit other large-format printers, we recommend using this plate exclusively with the qidi max4 for optimal magnetic adhesion and thermal uniformity. Whether you own a standalone Max4 or the qidi max4 combo, this build plate is the ideal replacement or upgrade. Enjoy hassle-free print removal, zero adhesive residue, and consistent performance – a must-have for every qidi max4 3d printer owner
