Paragraph starter
The research by Tronvoll (2023) demonstrates that additive manufacturing offers a viable and cost-effective solution for creating customized tooling in processes like rotary drawing bending. By fabricating mandrel dies using FFF, the cost barrier for low-volume production and prototyping of bent tube components is significantly reduced, with comparable quality to conventional metal tooling.
