Terahertz (THz) Optical Parameters of Three-Dimensional (3-D) Printing Materials

Abstract

With the development of Three-Dimensional (3-D) printing as a rapid prototyping and low production rate manufacturing technology, the internal composition and structural quality of prints need to be known and quantitatively measurable. Submillimeter wave or terahertz (THz) radiation is a valid candidate to see through these visibly opaque structures and can be used to reveal a 3-D model as part of the nondestructive test and evaluation process (that is, quality control). This report discusses the terahertz spectral optical characteristics of bulk printing materials commonly used in 3-D printing.
