TY - JOUR TI - Dimensionless analysis for the 3-D printing process AU - Zuo Yu-Ting AU - Li Xiao-Xia JN - Thermal Science PY - 2025 VL - 29 IS - 3 SP - 1701 EP - 1704 PT - Article AB - The dimensionless analysis is a highly effective mathematical tool for the physical comprehension of intricate phenomena. This paper employs the aforementioned mathematical tool to study the 3-D printing process. A number of criteria for a precise printing process have been identified, which can be used to optimize the printing process and offer a new strategy to improve its printing accuracy.
