Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional fabrication methods, including additive manufacturing, face inefficiencies due to the need for skilled labor and high overhead costs associated with configuring manufacturing settings and part orientation, especially when printing multiple copies of parts on a build plate.
Innovation Solution
An automated layout process where a factory server generates a 2D footprint for each part instance and uses a two-dimensional packing algorithm to arrange them on a build plate, optimizing the layout and reducing the need for manual intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a 3D packing process is used to place different part instances on the build plate, then the layout can be automated, but the process becomes relatively computationally intensive
Solution Approach 1:
The patent transforms the 3D packing problem into a 2D packing problem by projecting part instances onto the build plate plane. This dimensionality reduction maintains the essential layout optimization functionality while dramatically reducing computational complexity, allowing automated layout generation without excessive computational resource requirements
2Ease of operation
If a factory operator manually manipulates part instances to create the layout, then flexibility and control are maintained, but the process becomes time-consuming and inefficient
Solution Approach 1:
The system enables automated self-service layout generation where the factory server automatically performs footprint generation and 2D packing operations without requiring manual operator intervention. This eliminates time-consuming manual manipulation while maintaining operational control through programmable algorithms that optimize part placement automatically
3Manufacturing precision
If traditional forming methods with template components are used, then parts can be manufactured with consistent quality, but overhead costs increase due to expensive template components
Solution Approach 1:
The patent extracts and removes the template component from the manufacturing process by using additive manufacturing to directly fabricate parts without requiring reusable molds or templates. This eliminates the overhead costs associated with template components while maintaining manufacturing precision through digital modeling and controlled deposition processes

AI summary
A method for generating a quote for fabrication of a part to be fabricated is disclosed. The method includes receiving, from a customer device associated with a customer, a design request for a part to be fabricated by a fabrication process. The design request includes a three-dimensional (3D) model file representing the part to be fabricated. The method further includes generating a feature vector for the part based on the model file and determining a total height of the part to be fabricated. Further, the method includes identifying one or more candidate orientations for the part to be fabricated and generating, as a function of a geometry of the part and a candidate orientation of the one or more candidate orientations, fabrication parameters for the part to be fabricated, wherein the fabrication parameters include a cost to fabricate the part and estimated completion date.
