Development of a Design-to-Print Philosophy Focused on Economical Efficiency

Language: ENG

STELIA Aerospace designs and produces aerostructures, pilot seats, business as well as first class passenger seats. These activities can benefit from additive manufacturing with appropriate design.

Nowadays, AM is often associated with strong optimization to find the top mass performance ratio through organic designs. Economically speaking, this can lead to nonsense as it overlooks manufacturing aspects.

In this work, implementation of production goal is achieved to define the most economically efficient design of a Pilot seat armrest: From an initial assembly of multiple parts from different processes and materials, powder bed fusion offers the opportunity of a single part design. A focus is set on part functionalization, topological optimization considering printing steps, and finally, parts orientation, printing parameters and nesting optimization of the batch to improve productivity. Then, this engineering philosophy has been validated with In this work, the implementation of the production goal is achieved to define the most economically efficient design of a pilot seat armrest. From an initial assembly of multiple parts from different processes and materials, powder bed fusion offers the opportunity of a single part design. A focus is set on part functionalization, topological optimization considering printing steps, and finally, parts orientation, printing parameters, and nesting optimization of the batch to improve productivity. Then, this engineering philosophy has been validated with printing tests of full batches of parts. Abuse loads tests on the armrests have permitted to check material and performances.

As a conclusion, the result of all these steps is the development of a specific design-to-print philosophy in accordance with AM industrial performance. Weight savings are confirmed by these new designs and process, and reaching the target costs could lead to potential production.
