In the context of sustainability, the development of optical fiber sensing technology and 3D printing technology brings new sustainable manufacturing solutions for the furniture industry. Based on the current status and development situation of the application of optical fiber sensing technology and 3D-printed furniture, this paper proposes the concept of applying embedded optical fiber sensing technology to traditional furniture manufacturing as the intersection of traditional furniture design and 3D printing technology. This design method is applied in furniture design cases, the stability of the 3D-printed structure after the optical fiber is embedded in the structure is verified through experiments, and the integration of the embedded optical fiber light-inducing and monitoring technology is used to assess the intelligence of furniture. It is found that by applying optical fiber sensors to furniture intelligence, the real-time monitoring of the environment, temperature, humidity, and other parameters during the use of furniture can be achieved, thus improving the energy efficiency and comfort of furniture. This innovative design idea and method provides a new direction for the sustainable development of furniture products and encourages the furniture industry to move forward in a more environmentally friendly and intelligent direction.

This study discussed the application of optical fibers in addressing the problem of insufficient light harvesting and sensing health monitoring in ancient buildings. Based on three-dimensional (3D) printing technology to fix the light-harvesting lens and conducting optical fiber, develop the replacement parts that can be buried into the optical fiber of ancient buildings. By introducing the experimental application to improve the experimental quality of research and teaching. Firstly, it highlights the advantage that the optical fiber plus lens structure design can make the natural light introduced for a long time; secondly, it points out that the buried optical fiber structure design does not affect the warmth and sound insulation of the building; finally, the health monitoring of the building is realized through the proposed method of buried optical fiber sensing. The design scheme adopts a fiber optic light transmission and sensing system, which can realize the whole system’s corrosion resistance, after laying buried and low-cost operation.
