REPAIR

Optimizing Wear Resistance in Mold and Tool Restoration Using Wire Laser Additive Manufacturing (WLAM)

REPAIR is developing a wire laser additive manufacturing (WLAM) repair methodology to restore damaged molds and tooling, improve their wear resistance, and reduce the costs, lead times, and environmental impact of industrial maintenance.

Overview

The REPAIR project aims to optimize the restoration of molds and tooling damaged by wire laser additive manufacturing (WLAM).

It will study bimetallic repairs combining the tool material with a filler material possessing suitable properties.

A multi-scale experimental and numerical approach will link manufacturing parameters to microstructural, mechanical, and metallurgical characteristics, and subsequently to wear behavior.

Multiphysics models will simulate the thermal, metallurgical, and mechanical phenomena during deposition to predict the geometry, residual stresses, properties, and service life of the repaired area.

An industrial demonstrator will validate the methodology.

The project will help reduce the costs, lead times, raw material consumption, and environmental footprint of maintenance.
