SNCF Reseau investigates metal Additive Manufacturing (AM) with the ambition to leverage its potential in the rail network sector to benefit from a supply chain perspective as well as from an asset manager point of view. Laser powder bed fusion (LBPF) opportunities are quite uncommon in the rail network industry, particularly due to its current high cost. The design freedom of LBPF can nevertheless be very effective for specific consolidation or performance needs. This potential opportunity was identified during the development of a new product designed for the motorization of signal levers. Work has therefore been done with the startup Pint Innovative on the redesign of the part to maximize its performance and minimize its manufacturing cost. The generative design method was used for this purpose. We provide in this article an overview of this project focused on the design work.

摘要

SNCF Reseau investigates metal Additive Manufacturing (AM) with the ambition to leverage its potential in the rail network sector to benefit from a supply chain perspective as well as from an asset manager point of view. Laser powder bed fusion (LBPF) opportunities are quite uncommon in the rail network industry, particularly due to its current high cost. The design freedom of LBPF can nevertheless be very effective for specific consolidation or performance needs. This potential opportunity was identified during the development of a new product designed for the motorization of signal levers. Work has therefore been done with the startup Pint Innovative on the redesign of the part to maximize its performance and minimize its manufacturing cost. The generative design method was used for this purpose. We provide in this article an overview of this project focused on the design work.
