Abstract

The main objective of the CORERAM project is to understand to what extent appropriately validated virtual simulation environments (“digital twins”) can support the efficient development of innovative additive manufacturing processes for the production of structurally efficient sandwich panel cores, made of eco-sustainable materials. These structural solutions are made of thermoplastic polymers of natural origin and related composites and produced using flexible Robotic Additive Manufacturing (RAM) processes. The activities focus on the development and validation of “digital twins” capable of simulating the additive manufacturing process and predicting the structural response of the produced components, enabling the future development of eco-sustainable processes and components according to the “First Time Right” principle.

The project involves the development and validation of the following virtual environments:

  • simulation of the extrusion process of thermoplastic polymers and related composites (WP2), using computational fluid dynamics (CFD) techniques, in order to identify the optimal extrusion parameters;
  • simulation of the robotic deposition process, using Off-Line Programming (OLP) techniques (WP3) in order to identify the optimal deposition modes;
  • simulation of the structural response of components with the main purpose of designing efficient solutions for sandwich panel cores (WP4).

The partnership consists of:

  • Signo Motus srl: Innovative SME with R&D core business in robotics, ICT, advanced materials and AM;
  • ABR srl: SME with consolidated experience in mechanical construction, machine manufacturing and AM;
  • UniversitĂ  degli Studi di Roma Tor Vergata: Public research institution with consolidated experience in the realization of multi-physics computational models.
