Abstract

Systems and methods for additive manufacturing of vehicles are provided. An additive manufacturing apparatus can include a printer that additively manufactures structures for a vehicle, and multiple analysis components. Each analysis component can receive information based on a design model of the vehicle and analyze the information based on an analysis factor. Each analysis component analyzes the information based on a different analysis factor. An integrator can receives the analyzed information from the analysis components, update the design model based on the analyzed information, and determine whether the updated design model satisfies criteria. If the updated design model satisfies the criteria, the integrator determines printing instructions for the printer to print one or more structures of the vehicle based on the updated design model, and if the updated design model does not satisfy the criteria, the integrator sends information based on the updated design model to the analysis components.

First claim

What is claimed is:

1. An additive manufacturing apparatus, comprising:
(i) a printer that additively manufactures structures for a vehicle;
(ii) a plurality of analysis components, each analysis component being configured to receive information based on a design model of the vehicle and to analyze the information based on an analysis factor, wherein each analysis component analyzes the information based on a different analysis factor than the other analysis components; and
(iii) an integrator that receives the analyzed information from the analysis components, updates the design model based on the analyzed information, and determines whether the updated design model satisfies criteria,
(iv) wherein, if the updated design model satisfies the criteria, the integrator determines printing instructions for the printer to print the one or more structures of the vehicle based on the updated design model and wherein the printer receives the printing instructions from the integrator and prints the one or more structures using the received printing instructions;
(v) and if the updated design model does not satisfy the criteria,
(a) the integrator sends information based on the updated design model to the analysis components,
(b) the analysis components analyze the information based on the updated design model,
(c) the integrator receives the analyzed information, updates the design model based on the analyzed information, and determines whether the updated design model satisfies criteria,
(d) wherein steps (a)-(c) are performed one or more times until the updated design model satisfies the criteria,
(e) when the updated design model satisfies the criteria, the integrator determines other printing instructions and sends the other printing instructions to the printer and the printer prints the one or more structures using the other printing instructions.

2. The apparatus of claim 1 , wherein one or more of the analysis components includes a computer aided engineering (CAE) component.
