TLDR
In this paper, a comparison between two different technologies for metal part fabrication, the traditional high-pressure die-casting and the direct metal laser sintering additive technique, is done with consideration of both the geometric possibilities of AM and the economic point of view.Abstract:
Additive manufacturing (AM) of metal parts combined with part redesign has a positive repercussion on cost saving. In fact, a remarkable cost reduction can be obtained if the component shape is modified to exploit AM potentialities. This paper deals with the evaluation of the production volume for which AM techniques result competitive with respect to conventional processes for the production of end-usable metal parts. For this purpose, a comparison between two different technologies for metal part fabrication, the traditional high-pressure die-casting and the direct metal laser sintering additive technique, is done with consideration of both the geometric possibilities of AM and the economic point of view. A design for additive manufacturing approach is adopted. Costs models of both processes are identified and then applied to an aeronautical component selected as case study. This research evidences that currently additive techniques can be economically convenient and competitive to traditional processes for small to medium batch production of metal parts.read more

A Game Theoretic Approach to assessing Additive Manufacturing as a Strategic Choice
TL;DR: The conventional wisdom of choosing between flexible manufacturing technology and dedicated tool-based technology holds in the case of AM given there is no demand uncertainty, but once the demand uncertainty is taken into account, a game-theoretical analysis is essential to examine the profitability of switching manufacturing technologies to AM.

Rapid Manufacturing of Metal Components by Laser Forming
TL;DR: In this article, the main driving force of rapid prototyping or layer manufacturing techniques changed from fabrication of prototypes to rapid tooling (RT) and rapid manufacturing (RM), and nowadays, the direct fabrication of functional or structural end-use products made by layer manufacturing methods, i.e. RM, is the main trend.
