3D printed gratings made from commercial acrylic resins were tested for the polarization control of IR-THz beams. Acrylic gratings showed spectral regions where the dichroic ratio Dr >1 and < 1 implying importance of molecular and/or stress induced anisotropy. Metal-coated 3D-printed THz optical elements can find a range of applications in intensity and polarization control of IR-THz beams. Bragg (thick) gratings can be printed by control of the exposed length of the grating beams during 3D printing allowing for an arbitrary thickness.
