摘要： An improved apparatus and method are provided to remove powder from a web, for example, in a 3D printing apparatus. A flexible blade is provided to contact and move across a first portion of the web located between adjacent portions of the web to scrape powder from the first portion without removing powder deposited on the adjacent portions. A pair of edge vacuum nozzles and a central vacuum nozzle are also provided to move with the flexible blade to remove powder from both edges of the first portion and a central region of the first portion.
