Measuring Haze, Transmittance and Colour of Clear 3D Printed Stereolithography Resins

The purpose of this report is to describe the development process of a test method that accurately quantifies 3D printed polymers for haze, transmittance and colour. The need for the development of this test method is at the forefront of the evolution of standards and practices in the additive manufacturing industry. Standardizing of a method developed for haze, transmittance and colour is critical for quantitative assessment of printed resins. The resulting method is particularly applicable for development and formulation of stereolithography (SLA) resins denoted as aesthetically clear or near clear and low in colour.
