Abstract
In this work, an original way of shaping chalcogenide optical components has been investigated. Thorough evaluation of the properties of chalcogenide glasses before and after 3D printing has been carried out in order to determine the impact of the 3D additive manufacturing process on the material. In order to evaluate the potential of such additive glass manufacturing, several preliminary results obtained with various chalcogenide objects and components, such as cylinders, beads, drawing preforms and sensors, are described and discussed. This innovative 3D printing method opens the way for many applications involving chalcogenide fiber elaboration, but also many other chalcogenide glass optical devices.
Highlights
In recent years, a growing interest has been developed for optical materials and fibers for the mid-infrared region, especially for chalcogenide glasses [1,2]
We have investigated an alternative approach based on a 3D printing process for fabricating mid-IR optical components such as preforms, optical fibers, sensors and beads
The comparison and energy polished before spectroscopy being analyzed toThe compare physical properties of the initial glass with the initial composition the glass indicates that there is no change in the chemical to those of the printed glass.ofThe composition of the pellet was determined by energy composition during the printing process
Summary
A growing interest has been developed for optical materials and fibers for the mid-infrared (mid-IR) region, especially for chalcogenide glasses [1,2]. Such interest originates from societal needs for health and environment for instance, and from the demand for military applications [3,4]. Compared to oxide-based glasses, vitreous materials containing chalcogen elements, i.e., S, Se and Te, show large transparency windows in the infrared Depending on their chemical composition, chalcogenide glasses can be transparent from the visible up to 12–18 μm [7,8,9]. We have investigated an alternative approach based on a 3D printing process for fabricating mid-IR optical components such as preforms, optical fibers, sensors and beads
