Three-dimensional printer tool systems |
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. |

1. A method for operating a tool crib holding a number of tools in cooperation with a three-dimensional printer, the method comprising:
receiving a first tool from the three-dimensional printer, the first tool including an extruder received by the tool crib after being used in a three-dimensional printing process, the tool crib disposed in an operating envelope of an x-y-z positioning system within a build chamber of the three-dimensional printer; cleaning the first tool with a first active element within the tool crib; receiving a request from the three-dimensional printer for a second tool; and preheating the second tool with a second active element including a heating element for use in an extrusion process. |
