Entry level micromilling machines have a substantially reduced capital cost, and lower operating costs associated with them, compared to the state of the art micromilling machines. This paper presents the decision making process and complexity of comparing these two technologies given part requirements, time constraints and part features. Some decisions are trivial, while others require an in-depth understanding of the economics and technical aspects of the technology and the product. Insights gained from research and manufacturing of Micromilled parts are discussed as well as aspects that could impact a techno-economic model. The model aspects are then related to various product sectors each with an estimated market size. One of the outputs of the paper is a business decision framework to guide investors.
