A Cost Model to Evaluate the Economic Performance of Contour Crafting

A Cost Model for Additive Manufacturing in Construction

“…The workflow is shown in Figure 1. The analysis of the articles related to the cost of 3D printing in construction has shown that the majority of these studies have applied a methodology to calculate the cost of the construction of a reinforced concrete wall [18], [19], [20], [21]. These studies show that the productivity and cost benefits of AM increase with the complexity of the shape of the wall.…”

“…These studies show that the productivity and cost benefits of AM increase with the complexity of the shape of the wall. The study of Zhang et al [18] is the only aimed specifically at defining a cost model for 3D printing in construction, proposing an activity-based cost model, i.e., based on the activities involved in the Contour Crafting process. Krimi et al [20] focused on confirming that the high production rate of 3D printing lowers overall construction costs.…”

“…Although these works focus on the economic feasibility of using AM as a construction method, [18] is the only study that introduces a cost model specific to the construction sector; however, it does not consider some important cost components, such as overheads and post processing, highlighted by the cost models specific for the manufacturing sector analysed hereafter.…”
