Inkjet printing of graphene and 2D material thin films will play an important role in printed electronics. In this chapter, the present status and challenges in the relevant research fields are reviewed. The key processing steps for the thin film printing are systematically introduced, including ink formulation, jetting and patterning, ink drying, and posttreatments. In each step, the recent strategies and implementations for the improvement of the printed thin film quality are overviewed. Several promising applications based on printed 2D material thin films are discussed and the trends in the research fields are forecast.
