Various resin materials are used as materials for 3D printers, but rubber materials for 3D printers are still under development. Last time we reported curing reaction observation and reaction analysis of ultraviolet ray irradiation of rubber material for 3D printer with UV curable rubber base as base material. In-situ observation and reaction analysis of the curing reaction of the liquid rubber and the crosslinking agent which are base materials in the rubber material by rapid measurement of Fourier Transform Infrared Spectroscopy and analyzed the detailed curing reaction process and the results are announced .
