Additive 3-dimensional (3d) core design

A system comprising:

• a 3-dimensional (3D) core design engine configured to;
• determine, in a computer-aided design (CAD) model, an under-core ply of a composite part and a core footprint on the under-core ply specified for an additive 3-dimensional (3D) core to be manufactured via additive manufacturing for insertion into the composite part;
• compute a bottom core surface of the additive 3D core from the under-core ply and core footprint;
• access core design parameters for the additive 3D core, the core design parameters comprising core thickness parameters and core shape parameters that define the additive 3D core;
• and
• construct an additive 3D core design in the CAD model based on the computed bottom core surface and the core shape parameters;
• and
• a 3D core printing engine configured to store the additive 3D core design to support subsequent manufacture of the additive 3D core via additive manufacturing.

A non-transitory machine-readable medium comprising instructions that, when executed by a processor, cause a computing system to:

• determine, in a computer-aided design (CAD) model, an under-core ply of a composite part and a core footprint on the under-core ply, the under-core ply and core footprint specified for an additive 3-dimensional (3D) core to be manufactured via additive manufacturing and to be inserted into the composite part;
• compute a bottom core surface of the additive 3D core from the under-core ply and core footprint;
• access core design parameters for the additive 3D core, the core design parameters comprising core thickness parameters and core shape parameters that define the additive 3D core;
• construct an additive 3D core design in the CAD model for the additive 3D core based on the computed bottom core surface and the core shape parameters;
• and
• store the additive 3D core design to support subsequent manufacture of the additive 3D core via additive manufacturing.
