Water contact angles and dimensional precision of simple liquid crystal display 3D printed models and 3D printed channels

In this article we evaluate a range of commercially available vat polymerization resins in liquid crystal display (LCD) 3D printing for properties that make them useful for microfluidic applications. We report data for the water contact angle measured on different surfaces of a 3D printed cube, water contact angle anisotropy and the dimensional precision of simple 3D printed objects and 3D printed channels. We also include LCD 3D print settings, such as exposure time and layer height alongside scanning electron microscopy images for the different 3D printed surfaces. We hope the data will benefit other users and avoid some of the difficulties we first encountered when utilizing LCD 3D printer resins to design microfluidic devices.
