A probe for an additive manufacturing system includes a probe body having a first air port therethrough between an inlet and an outlet, and a location sensing probe extending from the probe body. The location sensing probe includes a probe end and a probe bar, the probe bar coupled between the probe body and the probe end, and a channel surrounding the probe bar, the channel having an inner tube having an inlet proximate the probe body and an outlet proximate the probe end. A method of determining a position of an item being printed in an additive manufacturing system, includes probing the position with a location sensing probe having a resolution finer than a print resolution of the print head.

Method of using a support structure as a fiducial for measuring position

In-situ part position measurement

An automated support cleaning system comprising a tank disposed within a housing and configured to circulate an aqueous cleaning solution to remove a support structure from a three-dimensional model.

A modeling apparatus includes a platform and a substrate, which are adapted to be releasably locked together to provide a surface for building up models in an additive-process three-dimensional modeling machine. The substrate comprises a substantially rigid, non-dusting tray providing a modeling surface. Male connectors extending from the tray are seated in female connectors in the platform, to engage the substrate to the platform. The engaged substrate is locked to the platform, maintaining accurate positioning of the substrate while a model is built. After modeling is complete, the substrate is released from the platform, the model is removed, and the substrate may be reused.
