ABSTRACT
3D printing, which covers from biotechnology to traditional handicraft, is developing rather fast. It has a history of 30 years in the development of interior decoration in China. It is based on mature technology and material. In general, interior decoration is secondary processing based on a house’s original structure. It must match the subjective demand of the customer and the objective demand of the society. Many new subjects have been developed in the past. As a new production tool, 3D printing has instant production capacity, which others do not have. However, the interior decoration industry has entered the bottleneck. The development of productivity will surely promote leaping development in this industry.
