Manufacturing three-dimensional (3D) objects with methods adapted from conventional digital printing have propelled the development of additive manufacturing. In this process, the printing devices directly deposit or fuse materials to form 3D solid objects in a layer-by-layer fashion, thereby creating the additive approach of fabrication.
As additive manufacturing (AM) has been increasingly adopted for rapid prototyping and part manufacturing, the need to determine the part quality which results from the processes becomes crucial (Monzón, Ortega, Martínez, & Ortega, 2015). There is a lack of quantifiable measurement systems to define a printer’s ability to resolve systematic and geometric features and dimensionalities (Moylan, Slotwinski, Cooke, Jurrens, & Donmez, 2012).
The purpose of this thesis is to develop a measurement system to determine a 3D printer’s capability to produce line features. The thesis will consist of (1) the development of a non-intersecting straight line target and (2) the method of measurement of the test target cross-sectional profile in three dimensions (i.e., x, y and z-axes) using a combination of optical microscope, a standard operating procedure for the measurement, the matrices to define line profile and a measurement systems analysis to determine the accuracy and precision of the measurement.
