11565358 · 2023-01-31 · ·

Methods involving adding a removable fixating material to a partially manufactured workpiece to stabilize a plurality of partially formed objects therein for subsequent manufacturing. In one example, a workpiece of interconnected structures is manufactured comprising precursors to the discrete objects as a function of a workpiece computer model. Manufacturing the workpiece further includes forming valleys between adjacent partially formed objects so that interconnecting portions remain to interconnect the partially formed objects. Further, the methods include removing the interconnecting portions so as to liberate the plurality of objects from one another. In some embodiments, a temporary frame is formed from the workpiece along with the plurality of objects during manufacturing.

System and method for planning support removal in hybrid manufacturing with the aid of a digital computer

Parameters of a set of tools are stored on a storage device. The tools are part of a manufacturing assembly usable for removing one or more support structures from a part. The support structures are formed with the part to facilitate additive manufacturing of the part. A near-net shape is modeled which includes the part combined with the support structures. A process plan is developed that includes subtractive manufacturing operations by the manufacturing assembly that remove the support structures. The process plan repeatedly updates the near-net shape as each one of the support structures is incrementally removed.

Support structures for additive manufacturing of solid models

Systems and methods for support structures for additive manufacturing of solid models. A method includes receiving a solid model, for a physical object to be manufactured, that includes a plurality of boundary representation surfaces. The method includes analyzing the b-rep surfaces to generate point samples for potential support locations. The method includes clustering points on the solid model, corresponding to at least some of the point samples, to create support locations. The method includes generating column supports in the solid model that connect to the original solid model at the support locations.

Optimizing support structures for additive manufacturing

An industrial asset item definition data store may contain at least one electronic record defining the industrial asset item. An automated support structure creation platform may include a support structure optimization computer processor. The automated support structure optimization computer processor may be adapted to automatically create support structure geometry data associated with an additive printing process for the industrial asset item. The creation may be performed via an iterative loop between a build process simulation engine and a topology optimization engine.
