Masters Theses

Abstract

"This thesis presents an effective cost model for the Selective Laser Sintering (SLS) process used in additive manufacturing practices. The various factors that influence the total cost of a build on both small and large frame machines are discussed. These attributes, which include labor and overhead rates, material costs, and process times, combine to generate the driving force behind a manufacturer's decision to use the small or large SLS machine for mass production. By developing and evaluating a current state value stream map for the small SLS machine, a financial analysis of the SLS process can be performed. By assigning a cost or rate to each of the steps in the SLS process, a total cost is calculated. Additionally, this thesis presents a functional Microsoft Excel tool that determines the total cost of a particular build in the small or large SLS machine when the user inputs the necessary information. This thesis uses information from published documents on SLS, papers and books written about effective cost modeling, value stream mapping, activity-based costing, and build time data recorded on-site in order to produce the tool that calculates the total cost of a build"--Abstract, page iii.
