Weak Interlayer Bonding in PEEK 3D Printing
문제 현상
【Problem Phenomenon】FFF printed PEEK parts have low interlayer peel strength, and Z-direction performance is far worse than XY-direction
원인 분석
PEEK printing requires a nozzle of about 400℃, a bed temperature of about 100℃, and an enclosed chamber for heat preservation; when the interlayer temperature gradient is too large, fusion and diffusion are insufficient, and interlayer bonding is inherently weaker than '2079851475616104452
해결 방법
Use an enclosed constant-temperature chamber printer and keep the bed temperature around 100℃; nozzle at 400℃ ensures interlayer fusion; optimize printing parameters by weighing interlayer strength against precision
핵심 요약
PEEK printing interlayer strength relies on chamber thermal management; open printers can hardly qualify; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
