Recently, development of the large-scale 3D products has attracted people’s attention. When printing the large-scale 3D products by using the FDM printer, the main problem is the distortion of the final products during printing. The distortion is caused by the thermal contraction of thermoplastic filaments. With the purpose of preventing distortion of the final 3D products, some FDM printers include the heating plate or glues, but these methods, in some cases, may not be enough to solve the distortion problem.
