摘要: An extruder or other similar tool head of a three-dimensional printer is slidably mounted along a feedpath of build material so that the extruder can move into and out of contact with a build surface according to whether build material is being extruded. The extruder may be spring-biased against the forward feedpath so that the extruder remains above the build surface in the absence of applied forces, and then moves downward into a position for extrusion when build material is fed into the extruder. In another aspect, modular tool heads are disclosed that can be automatically coupled to and removed from the three-dimensional printer by a suitable robotics system. A tool crib may be provided to store multiple tool heads while not in use.
摘要翻译: 三维打印机的挤出机或其他类似工具头沿构建材料的馈送路径可滑动地安装,使得挤出机可根据构建材料是否被挤出而移动到构建表面和不与构建表面接触。 挤压机可以相对于前进路径弹簧偏置,使得挤压机在没有施加力的情况下保持在建造表面上方,然后当建造材料被供给到挤压机中时向下移动到用于挤压的位置。 在另一方面,公开了可通过合适的机器人系统自动耦合到三维打印机并从中移除的模块化工具头。 可以提供工具箱以在不使用时存储多个工具头。
