The Laserdyne® 795 is a machine equipped with Laser Metal Deposition technology, developed by Prima Additive and customised, considering the needs of the energy production sector, in cooperation with Enel, the main energy producer and supplier in Italy. Enel’s choice of a direct energy deposition machine has been determined by the flexibility of this solution, both in terms of production and repair. This type of application allows to reduce warehouse time, reduce downtime of a plant or parts of it, and to save money, allowing to repair and reuse the same component.
Before the purchase, Enel evaluated many case studies related to the role of the efficiency of components and spare parts on efficiency and availability of power plants, in addition to number, average stock, economic value, and types of damage of the parts.
This innovative solution, together with expertise in the metallurgical and testing available in the Santa Barbara plant, as well as the experience in the field of design, simulation and operation, and plants maintenance, will constitute a new and concrete opportunity for Enel Produzione’s activity both in Italy and in the rest of the world, as well as for the other Group companies, contributing to excellence in terms of innovation and technology.
The main reasons that led Enel to choose a solution developed by Prima Additive were the size of the work volume, the 7 degrees of freedom that could facilitate the repairability of some items, and the possibility to execute complex shapes (original or re-engineered). Other important features are the adjustable power of the laser source, the open scan parameters, the customised cad-cam, and the implementation of two separate powder adduction lines which, together with dust engineering aspects, allow a considerable development of the mechanical properties of the parts produced or repaired.
