CFK CNC-Fertigungstechnik Kriftel GmbH, a Germany-based company, has secured a contract with Deutsche Bahn to produce additively manufactured braille handrail signs for German rail systems. Collaborating with Schilderwerk Beutha, this initiative aims to enhance navigation for visually impaired individuals in train stations.
Using Laser Beam Powder Bed Fusion (PBF-LB) technology, CFK can create tailored handrail signs with diverse messages, inclusive of braille. These signs can vary in length, all within a single manufacturing cycle. A pivotal element in this process is the aluminum alloy Aheadd CP1 from Constellium, facilitating swift manufacturing while upholding quality standards. This approach offers both a decline in additive manufacturing part costs and elevated product efficacy.
Arvid Eirich of Deutsche Bahn emphasizes the need for industry specialists to craft bespoke 3D printing solutions, ensuring users have faith in additive manufacturing outputs. This could potentially hasten the shift to digital fabrication.
Since 2021, CFK’s Additive Manufacturing division has been experimenting with the Aheadd CP1 alloy, particularly in scenarios where traditional materials fall short in performance. CFK’s CEO, Christoph Over, believes that the introduction of this alloy enhances their product’s performance across various aluminum applications, potentially benefiting other transport entities seeking solutions for disabled individuals.
