A method for building a three-dimensional object containing an identification-tag insert, the method comprising performing a build operation to form layers of the three-dimensional object using a layer-based additive technique, placing the identification-tag insert on at least a portion of the layers during the build operation, and reading information from the identification-tag insert.

Method for building and using three-dimensional objects containing embedded identification-tag inserts

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.

Support cleaning system

A spool assembly comprising a housing structure, a spool rotatably retained in an interior region of the housing structure, and a sealed sheath encasing the housing structure to define a barrier for the encased housing structure and the rotatably retained spool. The spool assembly further comprises a locking arm disposed outside of the sealed sheath and configured to operably engage the spool through the sealed sheath and through the housing structure in a manner that does not penetrate the sealed sheath, where the locking arm prevents the spool from rotating relative to the housing mechanism when operably engaged with the spool. The locking arm may disengage from the spool in a hands-free manner when the spool assembly is loaded into a bay of an additive manufacturing system.

Spool assembly with locking mechanism for additive manufacturing system, and methods of use thereof

A spool assembly for use in an additive manufacturing system, comprising a spool rotatably retained in a sealed sheath in a hub-less manner, and a locking mechanism configured to operably engage with the spool to prevent the spool from rotating.

Spool assembly for additive manufacturing system, and methods of manufacture and use thereof

A liquefier assembly for use in an additive manufacturing system, the liquefier assembly comprising a liquefier tube, a rigid sleeve secured to an inlet end of the liquefier tube, an extrusion tip secured to an outlet end of the liquefier tube, and a hollow liner disposed at least partially within the rigid sleeve such that inner surfaces of the liquefier tube and the hollow liner are substantially flush, and where the inner surface of the hollow liner has a low surface energy.

Liquefier assembly having inlet liner for use in additive manufacturing system

A system for building a three-dimensional object with a layer-based additive technique, the system comprising a controller configured to receive build sequence data for the three-dimensional object, a head assembly in signal communication with the controller and configured to form a plurality of layers of the three-dimensional object based on the build sequence data, and an insert placement apparatus in signal communication with the controller and configured to place at least one insert in the plurality of formed layers based on the build sequence data.

System for building three-dimensional objects containing embedded inserts, and method of use thereof

A method for generating build sequence data for a computer-aided design model of a three-dimensional object, the method comprising identifying a location of an insert data representation in the computer-aided design model, slicing the computer-aided design model into a plurality of sliced layers, generating a plurality of support layers for at least a portion of the plurality of sliced layers, and generating an unfilled region in the computer-aided design model at the identified location of the insert data representation.
