Abstract: A scanning 3-D printing system comprises a printing platform movable in a printing direction and in an indexing direction, the printing platform comprising a printing head configured for dispensing building material while the printing platform is moving in a printing direction one pass at a time, and layer by layer, a roller configured for leveling the dispensed building material one pass at a time, wherein the roller is rotatably mounted on a roller axle, and wherein the roller axle extends over all passes of the printing system and is stationary in the indexing direction, a scraper configured for scraping excess building material off the roller, and a trough configured for collecting the building material scraped off the roller.

Abstract translation: 一种扫描3-D打印系统，包括可在打印方向和分度方向上移动的打印平台，所述打印平台包括打印头，所述打印头构造成用于在打印平台一次一次地沿打印方向移动时分配建筑材料， 并且逐层地设置用于一次一次地对所分配的建筑材料进行平整的辊，其中所述辊可旋转地安装在辊轴上，并且其中所述辊轴在所述打印系统的所有通道上延伸并且在所述索引中是静止的 方向，用于刮擦多余的建筑材料的刮板被构造成用于收集从辊子刮出的建筑材料的槽。
