Abstract: The paper mainly discusses the simulation and modeling of traditional loom – grass cloth loom by using 3D printing technology. The structure of the grass cloth loom, the 3D modeling process and the 3D printing process are digitalized, so that the data can be stored for a long time and widely exchanged, thus providing a digitalized and viable solution for the reservation and inheritance of intangible cultural heritage.

Key words: 3D printing; grass cloth loom; simulation technology; modeling
