Abstract

In the context of Industry 4.0, the integration of digital technologies in manufacturing process chains is in progress in several industrial sectors. In this study, additive manufactured polymer extrusion dies were fabricated by continuous liquid interface production and tested in an extrusion production line. The possibility to integrate direct soft tooling manufacturing along with a digital twin environment in the process chain was conceived with great potential time and production cost reductions compared to the conventional process. The dies successfully withstood the demanding process conditions, yielding up to 1000 m of products with process conditions comparable to the conventional process.
