Cost calculation process of offsite C3DP. First, Fig. 1 tells us cost composition of offsite C3DP as industrial product in the printing stage of C3DP components. In this stage, printing cost of offsite C3DP components consist of steel bar cost, concrete cost, pre-embedded piece cost, additives of printing material cost, and so on. The C3DP components cost include management cost, manufacturing cost, printing costs, transport cost, and value added tax in printing stage. Second, Fig. 1 also shows us cost composition of offsite C3DP as construction product in the assembly stage of C3DP components. In this stage, construction and installation expenses of offsite C3DP components consist of sub-engineering expense, cost of taking measures, other project cost, pollution discharge cost, and so on. The C3DP components cost include C3DP components price, procurement expense of equipment, construction and installation expense, and other expenses for engineering construction in assembly stage. The C3DP components price is the sum of all cost composition in assembly stage plus components profit. To summarize, cost of offsite C3DP is the sum of C3DP components profit, printing stage cost, and assembly stage cost
