Project co-financed under Tuscany POR FESR 2014-2020

Innovative Additive Manufacturing of fiber-reinforced composites for industrial and medical applications

MANIFOLD project proposes to innovate 3D printing technology, developing a new anthropomorphic printing robot for shoe making industry, for the production of shoe lasts in reinforced composite materials.

Shoe lasts have been presently manufacturing in thermoplastic materials by subtractive manufacturing with numeric control machines, and further reinforced locally with metallic inserts to guarantee the necessary stiffness to withstand solicitation during shoes manufacturing. Such shoe lasts are designed and machined to be coupled with the systems for handling and movement by robotized lines.

The shoe last manufacturing process have some limitations as low productivity, high last weight, limited geometric precision and the production of scraps due to mechanical machining.

 

INNOVATION

MANIFOLD project proposes the development of a very innovative process by using additive manufacturing technology with composite materials applied with an anthropomorphic printing robot arm, for the production of lightened hollow lasts and in the presence of undercuts. The use of fiber-reinforced composite materials allows obtaining lighter products with higher mechanical performances, compared with the state of art represented by 3D printed thermoplastics.

Such new process, proposing a revolutionary solution for making shoe lasts, allows reducing manufacturing times of 50% and last weight of 40%. Furthermore, in consideration of a wider use of CAD tools in the future by the stylists for shoes design, the proposed solution is expected to be particularly relevant for increasing shoe industry productivity.

The new additive manufacturing line of shoe lasts will be also equipped with sensors interfaced to IoT systems for the monitoring of energetic and technological performances, with the goal of developing a predictive maintenance system based on diagnostic algorithms generated by the big data analysis generated.
