Glass transition temperatures, melting temperatures, water contact angles and dimensional precision of simple fused deposition model 3D prints and 3D printed channels constructed from a range of commercially available filaments

Here we evaluate the properties of a range of commercially available 3D printer filaments that make them useful in fluid handling applications. Data relating to the glass transition temperatures, melting temperatures and melting enthalpies of the unprinted filaments are reported. In the printed state we report water contact angles and the dimensional precision of simple 3D printed objects and 3D printed channels. We also report the print settings, such as extruder temperature and build platform temperature, which enabled us to obtain the basic 3D printed objects used for testing. By making these data available we hope that other users may benefit and avoid some of the difficulties we first encountered when using novel filaments in our 3D prints, particularly when trying to construct watertight devices.
