Abstract

In recent years the field of additive manufacturing has evolved rapidly and the amount of available manufacturing methods and variations thereof are increasing at a rapid pace [1]. The characterization of new evolving additive technologies is an important tool when quantify the developments and the direction being pursued, both on an industrial application as well as technological research level. Continuous Liquid Interface Production (CLIP) additive manufacturing is a method developed as an evolution of the Digital Light Processing (DLP) principle by J. R. Tumbleston [2]. By utilizing an oxygen-permeable window below a ultraviolet image projection plane, the step-wise motion of the common DLP printer can be avoided by maintaining a persistent liquid interface, a so called "dead-zone", thus allowing for continuous growth of a printed specimen. This research investigates the capabilities of CLIP by manufacturing of specimens replicating existing metrological transfer standards, an optomechanical hole plate with 25 equidistantly place holes designed for coordinate measurement machine (CMM) characterization [3] and a ball plate with 25 equidistantly placed ceramic spheres. Using tactile coordinate machine measurements, the quality assessment of the manufactured parts is done investigating measurands including dimensions of 1D, 2D and 3D geometrical features as well as form errors.
