Design optimization of a 3D printed aerospace smart table

What is it about?

Topology optimization design tools and 3D printing technology can be used together to produce complex, light weight designs that are ideal for the aerospace industry. Multi-material topology optimization improves design freedom by selecting between candidate materials in different areas of a structure based on criteria such as stiffness, weight, and cost. In this research, 3D printed aluminum and plastic are explored as structural materials.

Why is it important?

This work uses a multi-material design tool to determine an optimized 3D printed internal structure for a smart table in a business jet aircraft. A conceptual design study compares a series of designs with varying ratios of materials. We conclude that metal 3D printing is ideal for the supporting the major structural loads, while plastic 3D printing can be used to provide general stiffness and to interface with electronic components.
