The general purpose of these designs are described in “3D Printed UV-vis Cuvette Adapter for Low Cost and Versatile Spectroscopic Experiments”, which is published in the open access journal ACS Omega. Link to publication:

This particular part is meant to mimic traditional quartz and glass UV-Vis Spectrometer cuvettes. In this design, we have a path length of 7 mm. This cuvette can be used in most standard UV-vis spectrometers. We recommend printing this design with a black filament to reduce the amount of light scattering.

An instructional video to assemble the spectrometer is shown below with the materials used listed. Either quartz or glass windows can be used depending on the spectral range needed of the cuvette.

Doesn't Matter




We recommend using supports that "touch build plate only" rather than having supports everywhere. Additionally, while we typically use a 100% infill to ensure water tightness, prints at infill levels as low as 10% were found to be watertight for over 2 weeks. For this print we used black polylactic acid (PLA) filament made and sold by MatterHackers. We highly recommend using black filament to minimize light scattering in the spectrometer.

3D printed objects were designed with SketchUp Make 2017 available free from Google (http://www.sketchup.com/). Designs were sliced using Cura for Lulzbot (https://www.lulzbot.com/cura), a free software that is based off of the more universal Cura software from Ultimaker (https://ultimaker.com/en/products/cura-software).
