PT. Adyawinsa Stamping Industries is a company that runs business processes as a provider of automotive components. Components are manufactured using a stamping process from a material material in the form of sheet metal. But with the development of technology and the concept of Industry 4.0, a new method in producing a metal component by adding the material instead of reducing the proportion of raw material material. The method is known as Additive Manufacturing (AM), so it raises a question of how effective the use of the AM method is rather than the existing production method, Substractive Manufacturing (SM). <br /> <br /> <br /> Both methods will be compared against each other by using cost parameter and production time indicator. The parameters are used to identify the economic lot point of each method, so that the AM method can be known how big its potential is compared with the SM method. <br /> <br /> <br /> In calculating the AM production time, an estimate is used with the model developed by Li. The production time is then used to calculate the total cost required during the production process. The cost model used also refers to the Li model with some changes with the intention of equating the cost components used in the SM method. <br /> <br /> <br /> The results of the cost comparison of the two methods performed, indicating that the AM method is considered more efficient at low quantity production, with an amount of no more than 185 units. If the time parameter used, then the AM method is considered more effective if the quantity of production does not exceed 5760 units. <br />
