TESTING AND MEASURING Additive Manufacturing of Rubber Parts based on liquid Rubber Polymers - Part 2: Development of low-viscosity Compound Formulations for use in additive Manufacturing

This publication shows the investigation of formulations and the production of sulfur-crosslinked compounds based on liquid rubbers for processing by means of additive manufacturing in the „Direct-Ink-Writing” process. This work follows on from the system engineering setup explained in Part 1 [1].

Additive manufacturing of rubber-based parts is a steadily growing branch of research. Depending on the dosage form of the rubber compound (e.g. as granules, as filaments or, as in this case, as a low-viscosity paste), there are different options for designing the processing-relevant hardware and developing rubber based compound formulations that can be processed with the respective machine setup.
