Computational Workflow for Three-Dimension Printing in Construction: Digital Tools and Methodological Limitations

Three-dimensional printing in construction (3DPiC) is known as a trending technology in the construction industry. While scholars and practitioners seek to learn more about the applications of 3DPiC, there are no efficient workflows and open data sets available for further investigations. This paper intends to present the data produced in a laboratory for creating new models. The paper first presents the experimentation data collected from 60 models, and selected thermal digital images can be used for further sustainability analysis. The recorded data includes the time of crafting each layer of the model, the total time of creating a model and thermal measures. Based on the 60 experimentations and an intensive literature review, the paper presents a proposed computational workflow, including the use of Revit, Dynamo, Fusion 360, Navisworks and a selected 3D printer, which can be utilised for further data collection and analysis in the field. This model will assist in automating the cost estimation as an upgrade for 3DPiC. This paper is helpful for scholars and practitioners since it shows how laboratory data can be helpful for construction operation design.
