Abstract:

An additive manufacturing deposition tool and cartridge system and method that allows for a preassembled cartridge to be dropped into a deposition tool, pressurized once, locked into place using a combination of a locating feature and tapered valve catch, where the deposition tool can deposit pressurized material by opening and closing a valve. The deposition tool can move up and down to avoid obstacles on the work surface, with the accuracy of the tool head height governed by physical hard stop devices, which allow an inexpensive motor to exert a force against a stop to precisely locate the tool head using inexpensive, low-precision motors.
