Will 3D printing subvert traditional industrial production? This is one of the problems that I thought of in the early days of design. As the most common printing method for 3D printing, FDM has its unique advantages and disadvantages. Therefore, I have carried out a series of explorations based on the characteristics of FDM. The finished product surrounds the integrally-formed chair back and the seat, and allows the computer to try a richer three-dimensional texture. Finally, the existing simple profile is used as the leg support to complete the combination of the integrated seat surface and the profile. Technically, it is also a detailed exploration and inspection of FDM.
